Guest editor Dr Simon Penson, Campden BRI

heat is no stranger to scientific research and technical development. As one of the world’s great staple foods it has been the object of testing and experimentation for centuries. Each stage of its production, from cultivation to milling to processing, requires care and attention in order to yield satisfactory results.

And as world consumption of the grain has increased over the past three to four decades, activity dedicated

Science, technology and collaboration: A recipe for success to helping enhance the consistency of end products has become increasingly sophisticated. A well-known example of the transfer of scientific findings to technical advancement is the C-Cell system, an instrumental method to objectively assess baking quality. Campden BRI developed the imaging technology behind this product that enhances millers’ blending and formulation of grists. It is also widely used by bakers to assess product quality and process performance, and seed breeders benefit from the technology in their assessment of new varieties. Yet, despite many such instances of innovation and development, there are still areas where wheat eludes us and significant knowledge gaps exist that need to be addressed. For instance, typical quality tests conducted on the grain by growers and suppliers are accurate most of the time. However, every miller can describe cases where, despite passing existing quality intake tests, a truck-load of wheat simply did not perform in process. That equates to many tonnes of wheat being certified as up to standard but not performing adequately once milled and processed as flour. This presents major problems, and wastage, up the supply chain.

Testing times ahead Current challenges and trends – at a global and local level – are compounding and expanding issues like this that face the wheat supply chain. Growers, millers, bakers and retailers alike have testing times ahead. The actions of the next five to 10 years will be pivotal in securing the long-term future of the industry and ensuring consumers continue to receive high quality, good value baked produce. Naturally, scientific research – and its translation into

technical developments – will play a fundamental role in the industry’s ability to address these challenges successfully. But collaboration between different sections of the industry, at all stages of the supply chain, is also vital. By forming a stronger, united front the industry will be able to deal with existing and emergent problems more thoroughly and more quickly. The genetics of baking and milling quality A good example of strategic, collaborative research has been cross-industry efforts to better understand the genetics of baking and milling quality. UK-based millers, plant breeders and bakers, together with technical experts from Campden BRI and academics from Rothamsted Research Dr Simon Penson, Head of Cereals and the John Innes and Milling, Campden BRI Centre, developed United Kingdom the genetic resources to enable fine examination of how different combinations of genes control baking and milling quality. The project has provided tools to plant breeders which benefit the whole supply chain. The project was managed by Campden BRI and funded by UK government and industrial partners. When devising research and development strategies to help future-proof the industry, an important first step is expert-led horizon scanning. It is only when the full scope and scale of future threats and opportunities is understood that focused plans can be developed. This is an area where a partnership approach between business leaders throughout the industry could prove hugely beneficial. One of the most significant wide-scale concerns confronting all food producers, not just the wheat supply chain, is the matter of food security in the face of climate change. This adds further pressures to existing challenges, such as management of production and maintaining quality of the grain and flour.

Exploiting nitrogen uptake Quality determination of wheat has traditionally focused on protein levels, with the nominal threshold

level of 13 percent commonly held as the ideal. Much Reducing energy use when milling attention has been paid to the use of nitrogen fertilizers Production cost concerns are a further common theme to maximise the protein potential of wheat crops. Yet throughout the wheat production process, and this is despite growers’ investment in nitrogen input, there is another area where research programmes can bring added no guarantee that the harvested grain will meet the 13 value to the milling industry. percent threshold.

ne of the world’s best known brand names in pelleting machines returns to the market. Sizer Limited, which is now part of the Newburgh group of companies, is offering its own bespoke Orbit pelleting machines under the famous Sizer brand, as well as providing spares and refurbishment services for many other types of pelleting machine. Nick Finch, technical director at Sizer, who has been involved with the pelleting industry for over 30 years, says, “All over the world, the Sizer name is known for producing high quality pelleting machines, which are renowned throughout the feed industry. “It is fantastic to be able to build on this heritage, which goes back 4 | May - June 2010

over 100 years, and strengthen the support for our existing animal feed customers while launching into exciting new markets with a tried and trusted brand. “We offer the capability to produce bespoke machines to suit specific materials and have the expertise in-house to carry out trials of any material to assess its viability for pellet production. This is a great opportunity for customers to benefit from our knowledge and expertise to develop their own pelleting solution.” The original Richard Sizer company, which was founded in Hull, UK in 1899, played an important role in the design and manufacture of the very first pelleting machines back in the 1920s, under the world famous

Orbit brand. Since then, Orbit has become synonymous with high quality pellet production, as it still is today. As well as supplying new Orbit machines, Sizer will also supply component parts for many other pelleting press types, as Nick Finch explains, “We’re not just producing spares for the Orbit machines, but have the expertise to be able to refurbish, service, and provide spares for a number of other manufacturers’ pelleting equipment. “We provide a turnkey service, in roller assembly refurbishment for example, which is designed to reduce the lead time and therefore minimize downtime and maximize operational efficiency.” Roger Pearson, managing director of Sizer adds, “We have

a range of machines to suit every purpose and situation. “It is the technical expertise that counts and we have extensive knowledge within our team of providing pelleting solutions to suit customer needs in the animal feed industry. All this, plus we have the backing of parent company Newburgh, giving us direct links to the very best in high precision engineering.”

On-site refurbishment Sizer Ltd offers a full range of component for pellet machines, which includes providing an on-site refurbishment service and buying old machines for repair and resale. The company has an extensive stock of component parts, which means customers

Silo storage expanded at Camgrain APC

he new Camgrain APC site in the UK, which is in additional to the 150,000 tonne plant at Linton just a few miles away is now supplying wheat destined for bread making exclusively for Sainsburys. Having previously supplied 12 5000-tonne storage silos on this new site, Brice Baker had last year supplied four 12-metre diameter wet grain hopper silos, with aeration, to give a combined total capacity of around 4200 tonnes of pre-drying storage. Brice Baker also supplied the 40-metre conveyor bridge over the driers to feed the new silos, designed to carry four 300-tonnesper-hour conveyors. An additional 30,000 tonnes of flat bunker storage was added with under floor discharge systems. Brice Baker also supplied conveyors, screw conveyors and elevators totalling around 1.6 km of either 300 or 600-tonnes-perhour conveying equipment. Predictions over the next

decade of population increase and changes in diet, have highlighted the likely world-wide shortage of foodstuffs and cereal crops. Brice Baker has reacted to this development positively plans to invest in new equipment for the manufacture of silos using the latest corrugating plant and the purchase of steel in coil form. “The present factory is no longer suitable and this investment has also enabled us to seek for new premises to allow the plant to work efficiently,” says the company. Alongside this investment, new designs are being investigated so that Brice Baker silos will be easier to manufacture and erect using standard components. Deliveries across the world will also be made simpler by introducing such changes.

On-board weighing can add value to grain-handling operations

ver at the forefront of developing on-board weighing technology for use on agricultural loaders, RDS Technology Ltd in the UK offers a number of systems focussing on telehandler weighing applications and product handling and mixing requirements. As telehandler hydraulic systems are often more complex and integrated than those on other types of loader, RDS has developed a series of sensors and interfaces that compensate for the external influences on hydraulic pressure

increasingly found on modern machines. These innovative enhancements significantly reduce the effect of external factors on the weighing process such as uneven ground, vehicle bounce and speed of lif t , improving dynamic weighing on telescopics and also meaning obstacles such as pivot position on the boom arm, tilt pressure lock-ups and variable return pressures are no longer a factor. For some makes and models of telehandler, there is the option of installing a strain gauge. This measures boom

deflection, from which the instrument calculates loaded weight. These advances in telehandler-specific weighing result in increased accuracy and repeatability. For product mixing applications, the Weighlog 200 System measures, displays and records the net weight lifted based on the lift system hydraulic pressure. This makes it ideal for vehicle and machine loading and check-weighing operations. The Weighlog System offers up to five different weighing channels and a ‘grand total’ channel, which can then be printed for record keeping purposes. The selected channel displays the

current load in the bucket and upon confirmation, adds it to both the channel sub-total and to the grand total channel giving an overall summary of loading activity. The use of these channels enables the mixing and blending of a number of different products for differing requirements. These developments in the RDS telehandler weighing range now allow the end-user to take full advantage of the telehandler and use weighing data for a multitude of purposes including stock control and blending purposes.

ProPhorce AC 299: ®

A new acidifier that improves dEB

erstorp Waspik BV of The Netherlands has introduced ProPhorce® AC 299, a new highly cost-effective acidifier that improves the dietary electrolyte balance in addition to the benefits of acidifying feed. ProPhorce ® AC 299 is a dry, non-corrosive acidifier. It improves daily live weight gain, feed conversion and inhibits the

growth of pathogenic bacteria in the gastro-intestinal tract. The main benefit of the product, in addition to the benefits gained by applying an acidifier, is the ability to optimise the dietary electrolyte balance (dEB ) . In growing animals - such as swine and

broilers - optimising the dietary electrolyte balance enhances animal performance. A positive electrolyte balance has scientifically shown to enhance the growth rate of farm animals. ProPhorce ® AC 299 has consistently shown to enhance animal performance in piglet growth experiments (see Figure 1). It combines the advantages of an acidifier with the ability to manage the electrolyte balance and the antibacterial properties of the formic acid anion. Including ProPhorce ® AC 299 in the feed can give a signif ic ant reduction of the variable feed cost accompanied with an improved animal performance.

Product highlights • I m p r o v e s d i e t a r y electrolyte balance (dEB) • Improves daily live weight gain and feed conversion

• R e d u c e s l e g problems in growing animals • Inhibits growth of p at hoge nic bacteria in the gastro-intestinal tract • Dry and non-corrosive, can be used in premixes

On-line moisture control in animal feed Continuous

measurement of moisture and automatic water content control improves performance

fter having searched for over 20 years for reliable means of measuring moisture, temperature and density of products, Chris IÁnson, chairman of IÁnsons Bros Ltd in Iceland, now concludes that Intelscan has the right solution for feed manufacturers. “Combined with our control system from DSL we now have an instant and continuous display of the quality of the finished product and the Intelscan unit is now an integral part of our quality system,” explains Mr IÁnson. The Intelscan on-line microwave moisture sensor is usually installed at petfood, fishfeed and wood pellet factories

before and after the dryer and inside the cooler. This allows improved control of moisture content in real time. Working closely with clients in animal feed production, Intelscan is now introducing a new and improved way to continually measure moisture content in feed and automatically control the water dosing. “We have seen big increase in value, both in terms of savings in energy and less mechanical wear and tear but also in much higher product yields,” explains Olafur H Jonsson, managing director at Intelscan. Too wet products (above target moisture level) have higher risk of mould, shorter storage and cause customer dissatisfaction.

On the other hand, too dry products (below target moisture level ) me ans unnecessary energy consumption, increased die wear and wasted dry substance. The feed is continually measured for moisture as it exits the mixer. The Intelsc an w ater dosing software automatically calculates the required amount of water to be added to the mix, if needed, to maintain the required moisture level. The software also controls the water valves to ensure that the correct amount of water is added.

AgMark expedites operations at grain terminal with reliable control system by Kasa Industrial Controls

ormed by four US cooperatives in 1999, AgMark LLC provides warehousing and marketing services for North Central Kansas grain producers. At their grain terminal in Concordia, Kansas, AgMark receives crops from nearly 30 elevators throughout the region.

“Farmers send their grain via truck to our terminal for shipment,” said Derek Sandmann, operations manager at AgMark. “We pull orders from this pool of grain and we use shuttle trains to ship it out to buyers. It’s more efficient for grain producers to bring their bushels to a single location. Plus, it allows us to secure better prices for the grain.” Only a select variety of buyers can accept grain bushels via shuttle train. Those who can, however, prove to be a valuable asset for AgMark 10 | May - June 2010

and regional farmers alike. Their large selection of product ensures AgMark can easily fulfill large orders and those requiring specific ingredient blends. The shuttle train delivers grain at an expedited rate and AgMark receives benefits from railroad associations for using this shipping method. The company then redistributes the profits to the grain producers through the three cooperatives that own AgMark LLC. Along with experiencing increased business in recent years, AgMark now handles soybeans and corn in addition to traditional wheat and milo. Each truck must be efficiently unloaded and segregated based upon crop type. To keep pace with busy operations, in 2006 AgMark decided to expand their facility by adding two steel storage bins and a third receiving pit. This expansion also included an equipment upgrade to better automate their operations. Now, the company’s automated operations are handled by a new control system designed by Kasa Industrial Controls, based in Salina, Kansas. “The control system we created had to handle each of these individual incoming and outgoing areas. It also would be in charge

of aeration and conveyors for relocating and storing grain,” said Heath Roker, sales engineering at Kasa Industrial Controls. “This new system improved the facilities automated processes. It also ensured their operations could be efficiently and safely controlled and shut down, if needed.” Kasa’s control system allows AgMark to run the facility with a limited number of personnel. It also accommodates multiple processes at once. Personnel can load a railcar in one location and unload grain at a truck pit elsewhere simultaneously. “We selected user-friendly, yet powerful equipment that allows AgMark to maintain and control their system optimally,” Roker said. “We can’t afford any downtime - my business doesn’t run if their system doesn’t work,” Sandmann added. “Using Kasa’s control system, we’ve had fewer breakdowns and no downtime, so we can keep trucks moving through at peak times.” Kasa’s system was designed to run independent of other systems in the elevator. With this arrangement, if one piece of equipment must be serviced, the rest can remain in use. Everyday operations were made simpler due to Kasa‘s customised control system.

“This made it easier for new operators to learn the system and suited our operations, tailored to accommodate the parameters we use when we receive trucks or load rail cars,” Sandmann said. Another benefit of this system is the technical support Kasa Industrial Controls provides. Sandmann noted that if equipment must be serviced or parameters must be changed, the company is quick to accommodate. “With our previous automated solution provider, we had trouble with their customer service. They were based in the Northeast United States, so it was difficult to schedule an onsite visit. Phone support also often wasn’t sufficient,” Sandmann explained. “Kasa has been very flexible and versatile, quickly reprogramming the system when our needs change. Most reprogramming can be accomplished via phone or Internet—but if an onsite visit is required, they’re very responsive.” AgMark continues to experience an increase in truck traffic and bushels each year. The reliable solution Kasa Industrial Controls provided ensures the company can keep up with these demands. More information: Website: www.kasacontrols.com. AgMark: www.agmarkllc.com.

Senegal fortifies flour and edible oils

enegal is the latest country to pass regulations for fortifying wheat flour with iron and folic acid. The West African country also adopted standards to add Vitamin A to edible vegetable oils as part of its strategy to use food fortification to address nutrient deficiencies. Now, 59 countries require that at least one kind of flour is fortified with iron or folic acid, and these countries are at various stages of implementation. Senegal has three large wheat flour mills, each with a capacity of more than 20 tonnes a day. Senegal’s population is over 12 million and a 2005 Demographic and Health Survey found 84.4 percent of children aged six to 59 months (and 61.1 percent of women aged 15-49 years) were iron deficient. Iron deficiency causes about half the world’s cases of anaemia. Anaemia decreases physical and mental development in children, reduces work productivity in adults and contributes to maternal mortality. Flour fortification

helps prevent iron deficiency by improving iron status. Folic acid, if taken before conception and in the early stages of pregnancy, greatly reduces the rates of neural tube defects, and prevent related birth defects. Countries with established fortification programs have documented 26 to 40 percent reductions in neural tube defects. Vitamin A deficiency is the leading cause of childhood blindness. The 2005 survey in Senegal found that 61 percent

of the children younger than six years were affected by Vitamin A deficiency. Several FFI par tners have been involved in food for tification effor ts in S e neg al , including He le n Keller International (HKI), the Micronutrient Initiative (MI) and the United Nations Children’s Fund (UNICEF).

Flour mill design

Flour mill design by Jonathan Bradshaw

There can hardly be a more graphic illustration of a mill not being built to match the likely circumstances of an earthquake than the recent events in Haiti where the mill building was reduced to a pile of rubble in literally seconds. I donâ&#x20AC;&#x2122;t blame anyone for this since the building was originally built several years ago and those who designed and built it adopted best practice at the time.

he fact that this earthquake was stronger than anything felt in the region for some time just goes to demonstrate that there will always be situations that we cannot have foreseen.

Having said this there are many other factors to take into account when designing mill buildings. First, we must consider what materials we shall use to construct the building with. What are our criteria, how fast do we want to be in operation, what are the ground conditions, what are the local laws? For example, imagine we want to build a mill as a new entrant into the industry in somewhere like West Africa. As a new entrant we obviously need to have dock side facilities for offloading wheat and if we cannot acquire sufficient land within a port we may wish to consider a separate facility for wheat intake and storage and then take into account the need to transfer wheat to the mill at a later date when the vessel has left port. We also need to take a good hard look at the available draft within the port and approaches to it to make sure there is suf12 | May - June 2010

ficient depth of water to accommodate our chosen size of vessel. It may be that dredging is an economical answer or possible using dolphins far enough from the shore line where the water is deeper.

Concrete or steel? When it comes to the mill building itself then we really have just two options, concrete or steel. Concrete is invariably the favoured option since raw materials are almost always available locally and with reasonable supervision local labour can be used to build such a mill building. However, there may well be circumstances where steel has distinct advantage, particularly when the site is of poor structure. Steel is lighter than concrete and can be fabricated and erected much quicker. Overall build time to full commissioning can be reduced significantly by using a steel building, and it is easy to modify to accommodate changes as it is being fabricated and erected. Frequently, piles are used to strengthen the foundation of a building where it is weak and piling often pays for itself in the long run because the building steelwork can also be reduced in profile.

As an aside it is often common practice in concrete buildings to erect the wheat and flour silos from Concrete as well although there is no reason why steel silos cannot be used for wheat. Students of the old correspondence course will know, however, of the advantage and disadvantages of using steel silos for flour in comparison to concrete. Temperature changes for one thing are not transferred as quickly into the finished flour when concrete is used as compared to steel which allows such temperature change to be almost instantly reflected in product temperature. Obviously, whatever the circumstances and whichever is used then adequate ventilation is a must. Similarly, mill buildings made of steel require adequate ventilation, not only to keep the employees and operatives cool â&#x20AC;&#x201C; and hopefully productive - but also so the process is not adversely affected by swings in temperature and humidity.

Forward planning Once the building is erected and the installation of machinery is commenced it is to be hoped that forward planning has been satisfactory and there are sufficient

holes in the floors, in the right places to accommodate spouting and pneumatics and other pieces of plant that require access through the floors. It is easier to accommodate changes in steel buildings than in concrete but it is also easier to inadvertently weaken the building structure by making too many structural changes in a steel building after the building has been erected. A simple layout of a milling facility would be to have the intake and wheat silos at one end, close to the water and the supply vessels followed by the main mill building housing the wheat cleaning plant and then the mill. Flour and bran will normally be blown into finished product silos at the opposite end of the mill building to the wheat silos and these will, likely as not feed through packing machines into the main storage warehouses. All this arrangement will ideally be in a straight line to avoid using unnecessary power transferring products from one point to another when gravity can do the job far cheaper.

Other items, such as offices, maintenance workshops, staff welfare facilities and laboratories will need to be allowed for and apart from them being near to the mill there is nothing to be gained by having them in any particular places, suffice to say that the wheat laboratory may well be close to the intake point and the flour laboratory close to the packers. I am obviously referring to a mill where bagged flour is the prime product but I realize that there are more and more mills being built with bulk facilities and several are also being built in certain developing countries with plant bakeries very close by, if they are not built as an integral part of the whole facility. Certainly this is the case within pasta plants and semolina mills invariably being built side by side to obtain the greatest economies overall. Economies on maintenance, quality control, staff welfare and general administration can all be maximized by incorporating as many operations as is feasible and practical on the one site.

Grain cooling

Traffic flow and layout Several sites I have worked on over the years have adopted traffic flow as the main criteria for their premises layout. With one incoming weighbridge and one outgoing weighbridge, a circular route for vehicles around the perimeter of the site often proves to be an economical layout with minimum supervision of vehicles. Cameras and traffic notice boards serve to control traffic very well and also provide a good record of vehicle turn round time and precise data as to when vehicles arrived and departed. The mill building itself is usually designed by the milling engineers and is then checked over by local structural engineers who may or may not be retained until the building is complete and machinery is installed. Use of contract managers is invaluable if you have nobody on staff who has carried out major works before, either civil or mechanical.

Attention to detail Electrical controls are usually supplied by milling engineers as well but transformers,

very few remote places in North America there are strict guideline on emissions and constant monitoring is now the norm with equipment being calibrated annually with the local authority being present at the time. Noise levels are also closely monitored and it may prove beneficial to house certain items of plant which generate high noise levels separately. This is certainly becoming the norm and most blower rooms are positioned on the side of the mill furthest away from housing and almost always these blower rooms are well insulated. It is easier and more economical to house such items separately when they are to be insulated since this greatly reduces the quantity of expensive acoustic insulation that is required.

Maintaining water volumes and quality generators, field wiring within the mill and laying of high tension cables may be subcontracted with good efficiencies being achieved. Invariably whoever carries out the electrical installation is the person who will subsequently maintain the plant and to be in at “the ground floor” will help in their understanding of the electrical wiring and the protocols which have been adopted. Most new mills are highly sophisticated in their electrical controls and so attention to detail is important. With auto roll gap adjustments, extraction monitoring and power recording as the norm, along with possibly on line testing of flour and automatic adjustment of additive feeders and wheat blends it requires people with advanced knowledge and skill to design, install and maintain the electrical control system in the mills of today. Fortunately most engineers have access to electrical contractors with the necessary capabilities and some even have a separate facility with suitably skilled staff within their own umbrella organization. Having said this there are some countries where the client wants the simplest mill he can obtain with no degree of automation whatsoever. In my opinion there is little sense in taking this approach since even in places where all the operatives are illiterate it still pays to carry out tasks automatically rather then rely on individuals to remember when various tasks are to be carried out.

Noise pollution and dust emissions Some other items which we need to consider are noise pollution and dust emissions to the atmosphere. In most places except the 14 | May - June 2010

All mills require water for damping of wheat and whilst we do not have the problems nowadays of disposing of the contaminated water from washers and whizzers we do still have the problems of maintaining water quality and holding sufficient water in storage to provide adequate pressure for operations. Invariably we see the water tanks being placed on the top floor of the mill close to tempering devices and with separate feeds down through the mill to provide adequate pressure and supply to offices, laboratories, canteens, workshops, toilets and showers. Sprinkler systems usually have their own supply of water which only need topping up whenever sprinkler tests are carried out. In some instances it is however illegal to store water because it is such a scarce commodity. In such circumstances it is usual to sink a bore hole to provide an adequate supply of potable water although I have seen some rather shallow bore holes which left a lot to be desired in terms of water quality, often only rectified by sinking the bore deeper.

Security Security is another consideration, particularly where there is a history of forced entry into premises in the area or where fraudulent practices are deemed acceptable. Depending on the country arrangements for security may range from a van coming by the mill premises a few times each night through to armed patrols being on site at all times with locked gates, machine gun platforms and observation points being the norm. It very much depends upon the culture of the country as to what level of security is required. The choice is yours.

Feature

And finally may I say that there are two ways to design a mill, or a site, the first being to obtain a good layout from a practical point of view and the second one being to start with the customers specification for flour and then work backwards through the flow sheet requirements and then building criteria to house such a mill. I generally favour the latter but the former can often work well particularly when local bakers and traders are the customers and the mill is producing general all purpose bakers’ flour as its main product. In both cases however the plant must be laid out with plenty of access room to individual machines because if operatives cannot work on a piece of equipment easily without getting knuckles cracked and knees rapped they simply will leave it alone, with all the knock on effects that has on flour quality. Getting involved from day one of conceiving of the mill design and layout will proves extremely beneficial and as I always advocate regular walk rounds of the mill that is in operation I can strongly advocate twice daily tours of the site whilst under construction. If work is being done to the upper floors and for one reason or another your presence is not welcomed then take a pair of binoculars with you and take a good look from ground level. Always hold regular site meetings to monitor progress and deal with other design issues that may crop up periodically. Always make sure contractors know where they stand on an issue, be clear with you instructions and listen to the counsel of those wiser and more experienced than you are. You will find that the ‘Old Hands’ take great pride in their work and will help you along well so long as you look after them in return.

Grain storage The Canadian way by Harry Harms, P Eng Manager, International and Commercial Sales, Westeel, Canada

or years Canada has been known for its quality grain, revered for its milling and processing quality. Although there is no doubt that this starts from good seed and crop management, the reason Canadian farmers can deliver quality grain around the world is because of its grain handling system and post harvest technologies.

The grain handling system starts at the farm as the grain is harvested. In Canada, unlike most other countries in the world, the vast majority of the grain is stored on the farm as it comes off the combine. Fifty years ago this was in small segregated storage of maybe 50 tonnes. It was not uncommon for a farm to have five, 10 or even 20 such small storage

16 | May - June 2010

bins. Each bin had a designated crop. It could be for high protein wheat or maybe feed wheat or barley or oats. But the crop was immediately segregated in order to preserve the quality. The best quality grain is never mixed with lesser quality. Today, bins have become larger as farms have consolidated, fields have gotten larger and productivity has increased. But the basic idea of segregation at harvest has been maintained.

On farm storage also becomes the first step in the grain conditioning and management cycle. With segregated storage grain is easily monitored and conditioned. Aeration systems which are used to cool the grain can also be used to control moisture content of the grain and suppress insect infestations and activity. And if a problem does occur then it becomes much easier to deal with and much quicker to resolve. From the farm grain, is moved to gathering facilities commonly called grain elevators. In Canada these are strategically located on rail lines so that grain can further be moved to ports for export. Because the grain is segregated and conditioned on the farm, the grain elevator can gather the quantity and quality of grain from the surrounding area that is required for the market. If high quality grain is required, it is moved to the elevator by truck and combined with other grain of the same grade and quality. The grain is checked for infestations, moisture, and cleanliness as well as grade. If it needs to be dried, fumigated or

The basic premise of a grain elevator however is not grain storage but rather throughput.

Storage is handled at the farm. The grain elevator is for gathering and moving the grain to market. Because of this Canadian elevators are rather small by world standards. Commonly only 20- 30,000 tonnes storage capacity, they move 15 to 20 times their volume or upwards of 500,000 tonnes annually. However because of their small size and high throughput, they are very efficient and much lower in cost than a facility with 500,000 tonnes capacity. Receiving systems take the grain at rates that are matched to the volume of grain at which trucks bring the grain to the elevator, typically at rates of 300 tonnes per hour. But for loading railcars, they are designed to move grain at much higher rates so that upwards of 100 railcars can be loaded in 24 hours. At the port facilities grain is received from the railcars and checked again for grade and

Figure 1

logy o n h c e t g in ix m in e t a The ultim

Horizontal twin-shaft paddle mixers by Kees Rodenburg, Market Support Manager, Forberg International, Norway

efore Forberg introduced its twin-shaft paddle mixing technology, a coefficient of variation (CV) of 10 was acceptable. Today, a CV of five or less is the standard.

What led to this dramatic improvement in mixing accuracy? The answer is that the Forberg horizontal twin-shaft paddle mixer brought about a revolution in mixing. Imagine a chessboard as the image of a perfect mixture. How can practical mixing results get as close as possible to this ideal? In the twin-shaft paddle mixer, the specific speed of the rotor shafts combined with the specific positioning and angles of the paddle blades provide excellent transport of particles (see Figure 1 and 2). All particles in the mixture need air surrounding them to be able to move freely. 20 | May - June 2010

The filling level in the twin-shaft mixer is not more that 40 percent above the shafts. Thus, there is surplus space in the mixer to provide air around the particles so they can move freely. The twin-shaft paddles lift the particles up in the middle of the mixer in the fluidized zone, where mixing takes place in a weightless state. In this way, the particles are moved back and forth, up and down and across in all directions â&#x20AC;&#x201C; this is the freedom of movement that is essential if particles are to be mixed as randomly as possible (see Figure 3). All powder-

type products with all shapes and densities can be mixed in the ForbergÂŽ twin-shaft paddle mixer. In some conventional mixers, the transport of particles is simplified and unidirectional, which results in poor-quality mix and long mixing time. For some materials this can even be negative as the particles can be Figure 2

crushed, worn down or can start forming lumps. Because the product is fluidized, the twin-shaft paddle mixer is very gentle with the product. Extra force must be added, for example with choppers, in case any lumps in the mixture must be crushed. High speed rotating knives will create the force needed to crush soft lumps in the mixture.

Features of the twin-shaft paddle mixer Mixing takes place in a very short time. An average mixing cycle for dry mixing can be as follows: filling 20-30 seconds, mixing 40-60 seconds and discharging 10-20 seconds. This gives a total cycle time of 1.5–2 minutes. A relatively small twin-shaft paddle mixer will provide a large output – thus giving savings both in investment costs and space requirements.

This is can be done by means of quick connection nozzles (single component flat spray nozzles are most commonly used) for adding oil, fat, water, flavours, etc. Spraying of liquids requires approximately one minute ensuring the best possible distribution of the liquids in the powdered material. In this case, total cycle time, including spraying of liquids, will be as low as 2.5–3.5 minutes. Liquid should be sprayed at a specific angle and at a specific distance to obtain the best possible distribution. The particles rotate around their own axes in the fluidized zone, exposing the total particle surface to the liquid during rotation. The liquid will hit the particles and be distributed in the mixture. High melting point liquids, such as fats, can be sprayed in free flowing liquid state with special nozzle arrangements. Homogeneous mixing is achieved in the space of a few seconds thanks to the fluidizing of the material. All particles can be mixed (small, large, light, heavy, round, etc.) without segregation, since the forces of mixing are stronger than the forces of segregation during the mixing action in these mixers. Segregation only takes place when the

Various mixer designs The twin-shaft paddle batch mixer has been developed over several years. Today, continuous twin-shaft paddle mixers are available, notably Forberg's latest development, the rotating twin-shaft paddle batch mixer. Continuous twin-shaft paddle mixer The continuous twin-shaft paddle mixer has many of the same advantages as the twinshaft batch mixer. It is very gentle with the products, has low energy consumption, high capacity, little space requirement and flexible filling. Throughput is very significant as the average retention time is approximately one minute (see Figure 4). For obtaining good mixing quality in a continuous mixer, an accurate feeding of the ingredients is demanded. Continuous mixers are suitable for mixing a limited number of components, which have similar properties. One or two different liquids can be sprayed onto the product mixtures.

product is handled after mixing, so it is recommended to minimize the distance between the mixer and the packaging point to avoid segregation. The benefits of the mechanical fluidizing zone are gentle mixing, no segregation and very short mixing time. This gives savings in terms of minimal wear and tear and low energy consumption. Maintenance costs are also very low. The mixer's low energy consumption is an important consideration in reducing production costs.

Advantages of the rotating twin-shaft mixer: • Completely closed mixing chamber • Only one valve for charging and discharging • Reduced cleaning surfaces with integrated hopper • CIP (cleaning in place) is easy to realise. Washing water can easily be discharged through the washing-docking station • High production capacity due to short cycle times • Mixing under vacuum (as an option) enables the design of new production processes. Oxygen sensitive products can be mixed under an inert atmosphere • Less product damage due to missing edges of discharge doors • Smaller tolerance (minimised gap) between mixing paddles and mixer housing can be achieved • In comparison with stationary batch mixers, the new and innovative F-RM machines combine high mixing quality and short mixing time with the discharge behaviour and convenience of a cone bin The well-known rotating vacuum coater, F-RVC, has the same design as the F-RM but is reinforced and equipped with vacuum equipment. This machine gives the optimum result for deep core vacuum coating as used widely in high fat applications and medication lines (see Figure 7). tion. This results in a whole list of practical, operational benefits. The rotating mixer (called the F-RM) has one inlet valve in the top where the product is introduced into the mixer. The valve closes and the mixing cycle is started. After the mixing cycle has finished, the entire machine is rotated upside down and the product is discharged through the same opening as for filling. The machine is then rotated back 180° and is ready for a new charge. A feature for the F-RM is the automatic washing and drying of the mixer (see Figure 6). The F-RM is designed for the feed, food, chemical and pharmaceutical industries where airtight processes are a must and cleaning is critical. It is also possible to mix under vacuum, or under an inert atmosphere to avoid oxidation of highly sensitive products. Application of steam or liquid nitrogen for sterilisation or coating is another interesting option. 22 | May - June 2010

Research and Development Mixing and processing - Mixing processes will always be one of the core processes in feed and food manufacturing. The twin-

Feature

shaft paddle mixer is a versatile machine, in which many processes beyond mixing can be performed. Forberg focuses on further development of industrial processes, in close cooperation with customers and research institutions. In the field of poultry feed for layers conditioning of mash feed has been a new development. Steam heat treatment of mash feed - For many reasons, today’s most common poultry feed is pelletized, crumbled feed. There are several possible reasons for using this kind of feed. For instance, broilers do need as high as possible energy input in short possible time. Pelletized feed is cooked and sanitized. This gives efficient and secure nourishment for the birds. Finally, food regulations and the industry are based on established technology. Mash feed is now getting more widely used, mainly for layers. For layers, mash feed has several advantages. They are gained by using more time to eat. Structure feed is more natural feed and gives better development of the gut. Though the use of mash feed is mainly restricted to layers, mash feed is more natural feed than pelleted feed. The system technology offers the possibility to heat treat big amounts of mash feed without taking the detour through a pellets press and milling the pellets down later on. The process is more economical. Cooling of pellets is less efficient due to poor heat transfer rate (surface). The steam heat treatment system is designed as a batch system. It makes it possible do dose exactly and to achieve the correct recipe, hence controlling the nutritional value of the mash feed. In addiFigure 7

tion, it gives full control of the process and guarantee that the product will be uniformly treated. The main achievements of the process are: • Destruction of salmonellae. The product is a pathogen free feed by reduction of other bacteria spores in the mash • Production of feed with course structure. The use of a roller mill gives good results with mash feed • Feed with nutritional value that ideally meets requirements of the layers • Preservation of thermo-sensitive components during production process • In production of feed with coarse structure, the use of a roller mill gives good results with mash feed. Generation of fines is also minimal. • Steam heat treatment of mash feed leaves the natural structure of the feed unchanged. No fibers are destroyed during the treatment due to the gentle mixing in the twin shaft mixer. The end product has improved flow properties compared to traditional mash

feed because of gelatinization and micro agglomeration. The danger of de-mixing is hereby reduced, and can be reduced further by spraying of oil. For feed with optimum nutritional value mixing is a basic process. The steam heat treatment system also serves as a complete mixing plant. The feed is always perfectly mixed. Additional pre- and post-steam heat treatment mixing installations are not necessary. A modern mixer with mixing quality CV <5 makes over-dosing of ‘minor ingredients’ unnecessary. There is no danger for quality degradation of ingredients. The steam heat treatment system is a very flexible production method where addition of vitamins and other thermo-sensitive products can take place. More oil or fat can be added to the mash feed compared to pelleted feed. Spraying of acid in order to prevent further bacterial growth is also possible. The ‘gentle’ steam heat treatment of the feed ensures preservation of thermo-sensi-

tive components. There is no high-pressure treatment like in a pellets press. Vitamins and other thermo-sensitive materials like enzymes can be added after heat treatment. There is no need for encapsulated vitamins. There is no need for overdosing. The thermo-sensitive components can be dosed in the exactly needed amount after heat treatment of the product.

Peripheral machines

The use of

peripheral machines in flour mills of today by Jonathan Bradshaw

hilst there can be no disputing the fact that the rollermills and the sifters are the main, key machines within a flour mill, there are a host of other machines scattered around the mill, wheat cleaning, bulk storage and packing areas that have significant roles to play in maintaining or enhancing operational efficiency on a site and it is these machines I intend to look at in this article. Let us start at the beginning in the wheat silos where we see an intake separator, often

I don’t class the intake separator as a peripheral machine but I do class the magnet in the silo as being peripheral to the process. Magnets, wherever they may be, in the intake house, the wheat cleaning plant, scattered around the mill or in the bulk flour silo should have the material they collect examined regularly and for me that means at least once every eight hours unless there is a large quantity of product passing over them in which case twice a shift would be more acceptable. Looking at what has been collected on a magnet can often give warning of a disaster about to happen elsewhere. If a large quantity of sifter bolts starts to appear then further examination is required at the sifter since one or more is clearly about to fall apart.

“It pays to know your mill and screenroom but we must not forget the ancillary machines, they all have a role to play” much maligned and rarely maintained since it is such a simple piece of equipment which rarely breaks down or goes wrong. 24 | May - June 2010

New items appearing

In the wheat cleaning house the principal machine are all familiar to us but there are some new items appearing which need our attention. Colour sorters are common place now and often can be seen replacing cylinders and disc separators in the older, more established mills. In the new mills they are now the accepted norm and often just

a separator and a colour sorter is all that is required to provide a clean wheat stream to first break. However, colour sorters come under my heading of peripheral devices and they do require regular servicing, bulb changes and nozzle checks. The compressor which supplies air to these machines is definitely on my list of peripheral machines and needs good servicing if it is to work efficiently. We have a great dependence on clean dry air for many functions in our mills and I see many mills where the compressor is stretched to its limit due to the air supply having ever increasing demands placed upon it as additional machines are added. In my strongly advocated daily walk round the mill I recommend turning on the compressed air supply when the mill is not running. It is much easier to hear air leaks and track them down when plant is stopped and you would be surprised just how many traps and water separators jam open, costing you money when it is unnecessary. The principle of colour sorting is to use the diffused light to make the wheat grains “disappear” into the background which then allows impurities to be much more easily identified. If bulbs are not maintained then the wheat remains visible and the colour sorter will reject it. A good maintenance contract will pay dividends … literally.

The importance of calibration Damping systems are important and when operating accurately can improve the

condition of wheat to first break to such an extent as to allow the mill operative to set his mill up properly and optimize extraction rates. Calibration is required regularly and records of â&#x20AC;&#x153;as foundâ&#x20AC;? conditions should be kept to identify seasonal trends. For example if the local vegetable processing factory uses high levels of water in the season then you will need to make adjustments to allow for that. As we move on into the mill I would class the scales as peripheral machines, since they do not change the nature of the product as it passes through. Scales do however play an enormously important part in the running of the mill since all our information about mill efficiency, extraction rates, throughput rates etc comes from the scales, more often than not these days linked to a central processor that gives a continuous read out of the scale readings and the calculations which we would otherwise do long hand at the end of each shift. It goes really without saying that proper calibration is required on all scales and their proximity to blowing lies should be checked for any adverse effects on scale operations. The use of flake disruptors on the head reductions, detachers on the lower reductions and other similar devices, either positioned in the basement, on the top floor or mounted directly in the pneumatic lift all have an impact on extraction and ash. Keeping rotors in good order is of paramount importance and I believe it pays to change pins once a year ideally just prior to harvest. The number of rollermills in a mill has now drastically reduced since the mid-

&feed milling technology

Grain

1950s when mills often had two roller floors. The fact that if a roll was set to grind too hard then flakes were produced which were scalped off and lost down the coarse reduction side of the mill was apparent to most millers and engineers and hence the flake disrupter was introduced so that hard grinds could be achieved and any flakes could be broken down before they reached the scalping covers. Similar maintenance tasks should be carried out periodically on disruptors and blades should be kept sharp by running an angle grinder over them to maintain the leading edge. I also class sieve cleaners, throughs tray cleaners and other devices on purifiers and in sifters as peripheral devices and I believe that regular inspection of these and replacement of worn ones will give you a handsome return for very little expenditure.

Recognizing odours Regular strip down of sifters will reveal the tell tale signs of bug urine which has a

Bran Finisher very pungent and unique odour. So unique is the smell that many operatives do not recognize it and it goes unattended to. It pays to train all staff correctly to recognize this odour and also in the accepted practices for dealing with insects. Pheromone traps can help identify insects on the wing and also give warning that a fumigation should be performed. Pheromone traps should be logged and should not be placed anywhere where they are likely to be dislodged or fall off into the process. If you are not careful you could cause yourself more of a problem than you bargained for. Several sifter sections are prone to

sweating if not exhausted properly and careful attention should be paid to establish which sections are prone to this since when sweating or condensation does occur the sifter cannot perform properly and flour covers will simply blind over gradually. Spouts should be checked regularly under sifters that sweat to ensure moth frasse and webbing does not build up. If it does then spouts should be cleaned by “dragging”. Fortunately such evidence of insect activity is rarely seen these days. Definitely classed as a peripheral machine in my book but with a very important role to play is the bran finisher. Now fully recognized by most engineers, Satake in particular, this machine not only removes the last remnants of flour from bran but is also marshalls coarse stocks into a recognizable stream. Given the use of inclination in the new Satake machine the bran finisher can be used to great effect, especially as far as extraction levels are concerned.

The last ‘policeman’ Redress sifters are all important since they are the last ‘policeman’ in the mill. I am seeing more mills using level probes under redress sifters to tell the mill operative when the bag is full of excess overtails, indicative of a burst cover back up the mill somewhere. Drawing samples will quickly identify where the burst cover lies. As well as sieve cleaners being important then so too are roll brushes and other roll cleaners, criterion cleaners and similar These, when working correctly will enable the miller to set a good grind but if they are damaged or ill fitting the miller 26 | May - June 2010

will struggle all day trying to set a good grind. Screw conveyors collecting flour and being used to mix in additives should have the additives feeders positioned as far away from the discharge point as possible in order to attain a good mix. Additive feeders should be equipped with level alarms so that flour cannot be produced without the correct additives. It varies from country to country as to whether the miller or the baker adds the bakery improvers but it is becoming the norm for the miller to do it, hence it is vitally important for there to be good indication of low levels in all the feeders. In the case of mills who have an automated mill control system the mill will be sent into suspend mode whenever low levels of additives are reached rather than produce any flour that is not acceptable to the baker. Health and safety has precluded the use of gas to bleach flour but several mills still maintain agitators through which dif-

ferent flour streams may pass. Whilst this is somewhat over the top for most operations, I see no reason not to maintain agitators to assist with blending of flour additives. In the bulk flour silos and through to the packing plant there is usually a liberal use of magnets. My earlier notes about magnets applies just as much here as earlier in the flow.

Making a large investment Packing houses have changed beyond all recognition since the mid 20th Century. High speed packing using carousels has led to direct loading onto vehicles, occa-

sionally with very few, if any operatives at all. Such highly efficient items of equipment obviously require a sizeable investment and a large volume is needed to justify the expense. Well worth it however in the larger mills around the world. In these larger mills it is quite common to pellet the bran produced and in mills where there is a low demand for bran it is common to place the bran in the wheat silos as they are emptied and then transship the bran back to the origin of the wheat on the next available grain vessel. Occasionally larger mills will have their own feed mill and will use the bran as part of the diet for local livestock. In such cases they may bring in mixed cargoes of commodities such as wheat, maize, soy, etc to make up a balanced diet often using local ingredients such a guinea corn where available. And, finally, I include in peripheral machinery such items as generators, laboratories and vehicles used for transporting finished products locally. All of these need to be maintained, particularly generator sets. Where they are installed to supply power as an alternative to the main supply company it is done for reasons of continuity of supply and to maintain a constant voltage, not often achievable from the local power company. Using fuel from the incoming grain vessel to power the generators can show some economies, but there is little need to justify the expense of a generator set when the alternative is invariably no power supply at all. As a last comment, it is attention to detail that keeps all these peripheral and ancillary machines performing satisfactorily and daily walks around the mill and other processes will pay handsome returns come the days of reckoning. A simple check list of functions that should be examined daily is well worth keeping especially of the operations that are being monitored. It pays to know your mill and screenroom but we must not forget the ancillary machines, they all have a role to play.

GLOBAL GRAIN & FEED MARKETS Every issue GFMT’s market analyst John Buckley reviews world trading conditions which are impacting the full range of commodities used in food and feed production. His observations will influence your decision-making.

At the moment, oilseed/protein markets still have to see what the weather brings for Northern Hemisphere oilseed crops – and what South American farmers will actually sow later this year. However, if these projections

Big crops on the way

eather for northern hemisphere wintersown wheat and barley crops has remained mostly favourable in recent weeks and harvests prospects currently look promising. As expected, world wheat area has not dropped much in response to low prices and current estimates suggest output within 10m tonnes or so of last year’s bumper 680m tonnes. EU wheat production is actually expected to increase by 5m or 6m tonnes, creating a larger surplus over domestic and export demand – even with an extra 2m tonnes going to the new outlets in ethanol fuel plants. The spring planting season for maize, soyabeans and quality milling wheats has meanwhile got off to a record fast start in the USA where larger sown areas should also translate into higher production – a probable new record for maize if the rest of the growing season runs normally. Big South American maize and huge soya crops

are also keeping downward pressure on prices across the feed raw material sector. Sowing progress and crop development has been slower for spring wheat in Canada, parts of Europe, the former Soviet Union and Far East Asia after a long hard winter, followed by too little rain in some areas and too much in others. However, with no major weather problems yet, adequate crops are still being built into most analysts forecasts for these regions too. Global supplies will also be supplemented by huge wheat and ample maize stocks being carried in from last season. World barley production will be down for a second year running and below consumption but that will not require much stock drawdown. In Europe itself barley output should still exceed demand, keeping carryover stocks at the high level of the past two years. World sorghum, oats and rye supplies are also fairly well balanced. All this is promising for consumers’ costs in the year ahead. On the demand side of the market, world import trade appears to be starting to respond to cheaper grain and feed prices. US feed demand,

which - like Europe’ flattened in the past season, has shown signs of picking up. Stronger maize import buying has also been seen from some of the big Asian importers like South Korea and Japan.

so far, there are no windfalls for exporters like last year’s, when Iran turned around world wheat trade, emerging as the largest single importer when it took 9m tonnes. In fact, this year’s, Iranian crops may have recovered enough to allow it to export to its Arab neighbours. India is also exporting surpluses. Even so, forward markets for both wheat and maize continue to point ‘North’ with higher prices. This is especially true of wheat which this month displayed a hefty 17% premium on the Chicago futures markets for spring 2011 deliveries. The forward strength is mainly driven by ‘outside’ investors buying into distant futures markets on the assumption that grains are ‘undervalued’ versus other commodities and assets, that global economic recovery will ultimately

exchange rate which has spurred more EU export trade and raising the intrinsic value of grains in euros. The price rise was also exaggerated by a previous long standoff between farmers and consumers with their opposing views on the value of grain. When exporters and domestic users eventually started to run out of stock to cover their commitments, farmers and merchants had a strong hand to play and milling wheat prices leapt to three-month highs. Protein markets have been dominated by the conflict between tight US old crop and record global new crop supplies. Latin American soya output has met our most optimistic trade forecasts but slow marketing caused by weather, currency differentials, expensive Latin American freight costs and fears of Argentine farmer/port strikes has

cost of this will halt EU growth have seen the euro plummet to four-year lows versus the dollar as we go to press. With some financial analysts questioned the long term survival of the euro itself, it seems likely that the currency will stay under pressure for some time yet, keeping EU cereals more expensive than expected – at least until the next crop is seen to be on its way and farmers have to clear more bin space. Last but not least, world financial / commodity markets are also watching US and European government moves to curb the influence of speculative money in grain futures markets with their huge influence over the cost of grain in physical markets. Given the key role the ‘outside’ forces played in the record grain price boom of the previous season, such curbs will doubtless be welcomed by grain and feed consumers.

Commodity highlights -

expand demand at a faster rate and/or that something major might eventually go awry with crop weather. However, until there is any evidence to support that view – and with supply/demand fundamentals as slack as they are right now - it remains very hard to see how higher forward prices can be justified. Consumption of wheat, outside of shifts in feed demand (mainly caused by fluctuations in maize supply), is still growing only slowly over the long term and will not expand by enough in 2010/11 even to match this year’s forecast production. That means wheat surpluses are likely to keep growing in 2010/11, providing an ample security stock in the run-up to next year’s harvest. Ironically, the adequately supplied European wheat market has recently ignored this global/domestic picture of plenty to rise strongly over the past month. Most of this trend is down to the plunging euro/dollar

30 | May - June 2010

forced top soya importer China and other buyers to keep mopping up remaining US old crop supplies. Some analysts see this buying (at a time when the world is facing a potential new crop glut of soyabeans) as evidence of a bigger problem with China’s own oilseed crop and perhaps a pointer to much greater feedstuff demand from this buyer down the road. Grain markets are also continuing to struggle with volatile ‘outside’ influences – the macro-economic markets like equities, gold, crude oil and currencies. Most of the news has centred on the problems in the eurozone and the interminable efforts made by German, French and other leaders to assure markets that Greece’s economic problems can be contained and will not be repeated across south Europe. But even a trillion-dollar rescue package put together in May has struggled to convince sceptics that the EU is back in control. Fears that the

Chinese maize demand offsets record US sowing pace Market-leading US maize futures prices have firmed up in recent weeks as big US crop hopes have been subdued by ideas that China might continue to raid world supplies to fill its growing deficit in this grain. China used to be a major maize exporter itself, overtaking Argentina as the second largest supplier earlier this decade on the back of annual rises in its domestic production. In recent years, however, China’s own crop expansion has slowed amid competition for dwindling agricultural land resources, droughts and other weather problems. At the same time, its domestic demand continues to reach new record levels, mostly driven by its expanding feed industry. As the price of corn on Chinese markets has begun to soar, the government has begun to make big inroads into its strategic reserve stocks, auctioning them off to feed users in an attempt to control the market. China is actually the largest maize stockholder by far outside of the USA with an estimated 53m tonnes at the close of this season (end of August( equal to about a third of its annual use (compared with the US which seems to be quite relaxed about hold less than 16% of its consumption in stocks).

year’s maize harvest was closer to 140/145m tonnes than the 155m accepted by USDA and others. Consumption on the other hand, is already at 155m and expected to get close to 160m this season. Some analysts think China will absorb the lion’s share of its maize production deficit by taking its stocks much lower and that it is only importing

completed at a record fast pace, taking advantage of some fine early season weather to pile in the seed with most of the crop already in the ground in mid-May. Last year, crops performed well despite the late start, delivering record yields for many farmers. This year’s flying start, an excellent moisture base and some warm

US maize now because it is much cheaper than domestic corn. They expect import purchases to slow markedly once China’s crop is seen to be up and running. Others are not so sure, questioning the accuracy of Chinese stock estimates and pointing to a late cold spring delaying Chinese maize sowing this year as possibly pointers to a greater deficit and perhaps 2m to 4m tonnes of imports this year (versus about 600,000 bought to date). However, even if that were the outcome, the world maize market should have no difficulty meeting this demand without causing a big jump in prices. The US, which exports about 50m tonnes a year (about 57% of world maize trade) is hardly short of supplies and expects to see its carryover stocks of this grain increase in the coming season. About 38m tonnes of maize exports should also be available from other suppliers, led by Brazil, Argentina, the Ukraine, other eastern European nations, India and South Africa. The world maize balance meanwhile looks reasonably healthy with production expected to grow by about 26m tonnes in the coming season as consumption increases by just 19m – so some stock accumulation on the way. The US maize crop picture could hardly be much different from that of the past two years when incessant rains delayed sowings well beyond what the prime sowing window for good yields. This year, sowing is being

weather in the near term forecast gives early promise of yields at least as large (though the USDA currently has them a little lower than last year’s). As always there is still time for a mid-season drought, a heatwave to spoil pollination or a wet harvest but unless conditions do turn unfavourable the crop outlook is very promising. Some sources also suggest US farmers might sow more than the officially forecast 88.8m acres, perhaps as much as 90m or more. That could push production from the world’s largest maize supplier up by 15m or even 20m tonnes from last year’s record 333.5m tonnes. Analysts are currently looking for a rise of no more than 10m tonnes in US domestic demand, mainly down to higher ethanol use (+7.5m) with animal feed up by perhaps another 1.5m. That would still leave the US able to export 5m tonnes more than in 2009/10, without eating into the comfortable carryover stocks carried in from last season. US stocks are larger than expected a few months ago after official surveys found less had been used than expected - despite ideas that lower quality from the wet 2009 crop might mean more grain having to be fed per head of livestock (see earlier GFMTs). Nothing in the US picture at present is remotely bullish for maize either in terms of prompt or forward delivery prices. Yet some of banks and investment houses have still been trying to talk the market up on the basis that this market is heading for an

32 | May - June 2010

ever tightening balance because supply isn’t growing fast enough over the long term to meet demand. In fact, world demand for maize, outside of the US and China and, to a lesser extent, Brazil, is only increasing slowly. While the US accounts for about 40% of world maize output, supplies are also growing overseas. South American crops now being harvested have turned out much bigger than expected and about 8.5m tonnes above last year’s rather poor results. Plantings in the former Soviet Union are also seen higher this spring. Ukraine this season managed to export 5m tonnes for the second year running – more than double its normal level and plans a 10% increase for 2010. Good crops in South Africa and parts of Asia have also been contributing more to world supply. The EU’s production is also seen rebounding this season to 57m from last year’s 55.6m tonnes, more or less in line with consumption (58m). Feedgrain costs generally will always be heavily influenced by maize which accounts for 45% of total world grain supply.

EU wheat prices up EU wheat markets staged a remarkable recovery last month as many consumers came in to cover long-delayed needs only to find farmers digging in their heels for higher prices. Primarily, the move reflected the weak euro stimulating more export demand for EU grain. However, it was also fed by bouts of strength in the US market, largely caused by speculators needing to cover some of their large short (sold) position in Chicago futures. However, while the US soft winter wheat crop, as traded on Chicago, is expected to be considerably smaller this year, stocks from last year are high and demand for this grade poor, especially on export markets where much cheaper European and ‘Black Sea’ (former Soviet Union) soft wheat has dominated most of the non-routine business for months. Higher up the wheat quality scale there is no lack of competition for business either. A lot of higher protein Canadian wheat has been available recently while quality wheat supplies are also said to have been piling up in Australia which failed to export as much as it needed to in the first quarter of this year from a bumper harvest. As a result, hard quality wheats have generally tended to come down in price in recent weeks. During May,

COMMODITIES US Dark Northern spring wheat for shipment out of the Gulf fell from $294 to $270/tonne compared with $325 this time last year. Hard Red Winter Wheat also slipped from $199 to $184 versus $243 a year ago. Unusually the lower grade Soft Red Winter wheat has been trading at a premium of up to $6/tonne over HRW compared with its normal discount of around $50/tonne. Along with the soaring dollar, this has shut the US out of most soft

rising sharply from Argentina (if the crop there recovers as expected) and moderately for Europe too, based on crop expansion, weak currency and smaller crops from key competitors in the former Soviet Union (currently expecting a 5m tonne drop in production). Canada will also have a smaller crop but Australia should have another large one and with countries like India and Iran also joining the export fray, keen competition

wheat import tenders as buyers paid up to $25/30 less for EU/Black Sea grain. Even US hard spring wheat is struggling to find enough buyers amid the competition from similar Canadian grades. World wheat production in 2010/11 is currently forecast by the IGC at 660m tonnes versus last year’s 675m due to slightly lower sown area and ideas that yields will probably slip from the past two years’ above-normal levels. The USDA is more optimistic, pitching output at 672m tonnes (680m) but has consumption at 667m (up 15.8m) versus the IGC’s forecast 654m (+9m). The biggest increases are seen in EU ethanol and feed demand (+3.2m in total) and former Soviet countries (mainly in feeds, +3.8m tonnes). Demand is also expected to rise in India and in aggregate in a number of smaller countries. The bottom line is that both the USDA and the IGC see world wheat stocks increasing next season - by 4.7m and 6m tonnes respectively. At 198m tonnes, USDA’s stock forecast for July 2011 would be over 73m more than the 2007/08 total and a nineyear high. USDA also sees world wheat exports next season staying fairly flat at around 129m tonnes with no notable swings in importing country trade. Plentiful supplies should keep competition for sales brisk with exports

for import customs should continue for some time yet. This should help keep the price of wheat down on international and EU markets.

Oilmeals/proteins Soya-meal costs had a brief run-up in April as top importer China continued to buy heavily from the US at the tail – end of the latter’s season. Latterly, however, prices of beans and meal have been working lower again amid confirmation of record crops in South American and an excellent start to the US planting and growing season. Latest estimates suggest China will import 49m tonnes of soyabeans in 2010/11 (starting September 1) – accounting for 57% of world trade. It was also consume about a quarter of all the world’s soya meal production (40m tonnes), putting it well ahead of the EU’s 32m and the USA’s 27.6m tonnes. In recent months it has surprised the markets by buying up the USA’s rapidly dwindling old crop stocks, partly because it is still cheaper to ship beans of the Northwest American coast than from Latin America and partly because of concerns that strikes in Argentina, port congestion in Brazil and slow selling by producers will result in delays in shipments from the Latin American origins.

This situation is unlikely to last much longer as the full weight of record Latin American soyabean crops comes to bear on the market. These are up by about 36m tonnes in a season when US output also rose 11m to a new record 91.4m tonnes. The total increase in terms of world soya meal equivalent is over 37m tonnes whereas demand for the latter is only up by about 7m tonnes this season. Soya meal prices have already eased in recent weeks on US and European market and, if the US crop continues to get good weather, the trend is expected to remain downward. Next year, supply may not be quite so loose as USDA expects soya production in South America to slip back by 7m or 8m tonnes. Even so, if the US crop again exceeds 90m, as currently seems likely, new supplies of soyabeans will again outpace growth in world demand, leading to carryover stocks (into 2011/12) rising to a new record 66m tonnes. Moreover, even if soyabean output does slip back a bit in 2010/11, USDA expects that to be offset by increases in supplies of cottonseed, rapeseed and sunflowerseed, leading to a decline in world oilseed production of just 2m tonnes. That will be eclipsed by an expected 75.5m tonnes of various oilseeds carried into the new 2010/11 season this autumn – 11m more than last year. At the moment, oilseed/protein markets still have to see what the weather brings for Northern Hemisphere oilseed crops – and what South American farmers will actually sow later this year. However, if these projections are anywhere near correct, consumers can probably look forward to some declines in oilmeal costs later in 2010.

Mycotoxins

Feature

Simultaneous determination of mycotoxins using immunoaffinity columns in conjunction with HPLC or LC-MS/MS If such testing (as outlined below) is used in conjunction with preventative measures at all stages in the production process, contamination risk to the consumer will be significantly reduced

flatoxin and Ochratoxin A were some of the first mycotoxins of interest and are produced by Aspergillus and Penicillium fungi when foods such as nuts, cereals, dried fruit, herbs, spices and coffee are stored under adverse conditions of temperature and humidity.

Over the years, legislation for mycotoxins in food has increased to incorporate additional matrices and toxins, such as the more commonly occurring Fusarium mycotoxins. This increase has placed pressure on laboratories to perform multiple mycotoxin analysis on an ever-increasing range of commodities. The result of this is an increased demand for faster and less labour intensive tests to allow more analyses “Over the years, legislation for to be performed in a shorter time period. mycotoxins in food has increased to Currently, there are a wide variety of tests available for incorporate additional matrices and the detection of mycotoxins.

Containment

Feature

Dinnissen Process Technology develops a

Hygienic Compact Containment System

innissen Process Technology, of Sevenum in The Netherlands, specialises in the processing of powders, particles and granulates for companies in the feed, food, pharma and chemical sectors.

In particular for environments where it is essential to work hygienically, safely and efficiently because of specific cleanliness requirements, explosion hazard and/or the potential emission of toxic or sensitising substances, Dinnissen has developed the Hygienic Compact Containment System. The concept combines the quick and thorough cleaning of production processes with an extremely effective containment of even the finest particles.

Quick and thorough cleaning The ability to quickly and thoroughly clean production processes is becoming increasingly crucial, as more and more producers choose to invest in a single process line for the production of several products. The quick and thorough cleaning achieved with the Hygienic Compact Containment System is based on its compact design and the fact that all the process equipment is quickly and easily accessible for cleaning purposes. This is also why Dinnissen fits its mixing and grinding installations with oversized inspection hatches and easily removable mixing shafts. As a result, all the interior parts of the machines are optimally accessible. 40 | May - June 2010

Fast cleaning and more batches per hour Dinnissen has succeeded in producing such a compact design via the use of accurate flow meters, dosage components and extremely accurate weighing systems. As a result, the systems supplied by Dinnissen can quickly and accurately dose various ingredients and process a large number of batches per hour. This makes it possible to achieve a high mixing capacity in spite of the compact design of the process equipment. This is possible even at ratios of coarse dosage/fine dosage of 1:500. In practice, Dinnissen’s systems allow coarse dosage rates of 20 tonnes per hour and fine dosage rates of 40kg per hour (11g per second). The compact design of the processing equipment is very important in enabling production processes to be cleaned quickly and thoroughly.

Cleaning the mixing and transport systems Dinnissen Process Technology developed the fully automated ‘dry-cleaning-in-place’ concept, based on compressed air, especially for companies which need to clean their mixing and transport systems quickly, efficiently and hygienically. The ‘dry-cleaningin-place’ technology cleans mixing systems completely automati-

cally using powerful blasts of compressed air and an interval switch. To achieve this, Dinnissen’s system employs tanks of compressed air and special nozzles installed at crucial locations in the mixing system. The equipment is blown clean on a stepby-step basis with the help of an interval switch, which ensures that the cleaning operation proceeds as programmed. The blow-cleaning process starts from the weighing bunker and proceeds, from front to back (or from top to bottom), to clean every component of the mixer and storage bunker with the help of blasts of compressed air. After each compartment has been cleaned, it is automatically sealed off by special valves to prevent any raw material particles from moving backwards to previous parts of the chain. An efficient suction system removes all particles and dirt which have been blown away and transports them to a hermetically sealed section. This new technology blows weighing bunkers, mixers and storage bunkers clean and empty at efficiencies of 99.9 percent. As the entire cleaning process is done

with everything as dry as possible, caking, clumping and the growth of bacteria and moulds are also effectively prevented. After their removal, expensive raw materials remain undamaged and can be reused without any problems. In addition, the system offers significant benefits in terms of labour saving and reduced downtime when switching from one product to the next. For companies which need the very highest level of hygiene, Dinnissen can fit the ‘dry-cleaning-in-place’ system with extra options from its product range such as electrolytically polished surfaces.

Hermetically sealing-off process

in a safe direction, while potentially contaminated air is removed and transported elsewhere.

Developed for production processes Hygienic Compact Containment is particularly appropriate for use in projects which involve product intake, mixing, grinding, sifting and packaging for companies in the food, pharma and chemical sectors. Hygienic Compact Containment offers effective solutions for environments in which raw materials are processed for the production of probiotics, vitamins, baby food, meat products, dried herbs, graphite, toner, additives, nitrates, fine particles, sensitizing substances, substances which are associated with explosion risk and other raw materials for the chemical and pharma sectors.

The entry of fine particles and microorganisms is a threat to the hygienic production of foodstuffs, particularly for companies operating in the food sector. In addition, the emission of toxic and sensitising substances can pose a threat to worker safety, particularly in the chemical and pharmaceutical sectors. Dinnissen’s new Hygienic Compact Containment concept succeeds in hermetically sealing off production processes and preventing particles from coming in or out. The concept is based on a combination of three functionalities. First, Dinnissen establishes a situation of underpressure wherever ingredients are introduced into the system. The resulting pressure exerted from outside the system prevents any hazardous substances from escaping from connections and seams or joints. In addition, Dinnissen uses inflatable seals and air-seals with air pressure throughout the system. The end result is a hermetically sealed system, whereby dirt and microorganisms are not able to enter and hazardous substances are not able to escape. The use of underpressure and inflatable seals makes it possible to limit particle transmission to less than 0.1mg per m3 of air. The Hygienic Compact Containment system is even effective against extremely fine particles (down to More information: 10nm).

International Grains Council

The worldÂ´s top event for animal production Tuesday 8 June Queen Elizabeth II Conference Centre Westminster London

The new decade: towards greater market stability? The past decade has seen enormous expansion in the global grains and oilseeds economy, driven by growth in population and prosperity as well as by steeply rising biofuel and other industrial uses. Rising demand for grains was more than matched by increased production, especially after the price surges of 2007-08. World trade in wheat, coarse grains and rice rose by nearly 20% from 2000 levels; in the oilseeds sector, responding to substantially enhanced demand for both animal feed (especially from China) and biofuels, the total trade volume climbed by as much as 50%. The dramatic price swings and the global economic downturn in the last years of the decade not only presented grain markets with considerable challenges but also threatened the immediate food security of vulnerable populations and dented consumption trends, especially in the feed sector.

Medium-term forecasts suggest that trade in the major grains and oilseeds will see further growth in the next ten years as world demand expands further. While many buyers have significantly improved their ability to manage price risks, the possibility of sudden spikes, not always explained by unforeseen imbalances in grain market fundamentals, remains a concern. Importers, especially those developing countries heavily reliant on external sources of food supply, remain vulnerable to sudden changes in prices and ocean freight costs. While markets remain unpredictable, improvements in transparency and a better appreciation of likely future trends are vital ingredients for a more stable trading environment. The next IGC Grains Conference aims to improve understanding of global grain and oilseed markets by bringing together all sectors of the industry with government policy makers, to exchange views and consider likely scenarios for the new decade.
