stability greater than 2 hours. However, the starch used to hold pellets together has no real nutritional value for shrimp. Therefore a process that allows for starches to be replaced by protein can further support the goal of optimized feed conversion ratio. Nevertheless, there are quite a few additional factors to consider when determining the best process solution for your shrimp feed manufacturing facility. Shrimp feed can be produced either by pelleting or extrusion and each of these processing technique has its pros and cons. Here we make a side by side comparison to help processors determine the best course of action for their individual facility and circumstances:

Extrusion Intensive pre-conditioning is a decisive stage of the extrusion process. To prevent expansion of pellets out of extruder the meal ingredients must be kept at a precise temperature. Additionally, because of all the excess moisture added during both preconditioning and extrusion, drying is also mandatory so moisture stability can be maintained in the finished pellets. However, post conditioning can be eliminated from the extrusion process all together. Several benefits of extrusion include precise control over pellet Pelleting

The company has targets to grow this revenue stream to €20m over the next four years. Having sold over 30 machines to market in the past 5 years, CFE has increased CPM’s footprint and market share year on year, replacing belt motor machines in the main with direct drive, high capacity pellet mills. CEO, Con Lynch, plans to increase this number by a further 30 machines over the next four years. CPM’s Direct Drive Conditioners with T Shaped Paddles boast a high fill rate, steam injection at the rear of tube and an emphasis on mixing rather than transportation. These are the features which make CPM Conditioners the machines of choice in this neglected part of the pellet manufacturing process. Targeted as growth area, CPM’s heat treatment hygienic equipment is becoming the benchmark for poultry and pig, with signature installations across Ireland and the UK.

DSL Systems’ AutoPilot4Feed feed and grain mill control system is proven to provide the following benefits for pelleting and extruding systems: • Improve throughput and quality • Reduce energy • Minimise down-time and mistakes • Simple and intuitive operation • Comprehensive reporting and KPIs The system can control all aspects of a pellet press or extruder line; including BOAs, HFCs, long term conditioners, coolers, fats coaters and finished product bin routing. The pellet press and extruder control has been developed over many years and includes facilities to minimise (and sometimes eliminate) change-over times, self-learning temperature control, optimised start-ups, die life recording and advanced blockage detection. The system may be installed to control pellet press lines only or could be extended to control the entire mill including intake, blending, outloading and packing. Additional options include Plan4Feed which is a visual production planning tool that can help plan more efficient pellet press runs and

Condex (UK) Ltd

Our La Meccanica pellet mills carry a 5 year, no major service guarantee. This means that as long as the machines are maintained and greased in accordance with the manufacturers guidelines there will be no servicing costs for the first five years; no seals, no bearings and most importantly no down-time. With the roller design having the optimum angle of nip and the main rotor having a high inertia, the La Meccanica pellet mills are one of the most efficient machines on the market, outperforming larger machines as a result of the design and main motor being utilised to its full potential. No gearbox so no oil leaks around the pellet mill or into the feed. Condex also supply an extensive range of grinding, conditioning and ancillary equipment, ensuring our clients are able to meet the high demands of the industry with equipment designed and manufactured to the same high standards as our pellet mills. Our in-house design and installation services means we are able to tailor equipment and process lines bespoke to a client’s requirements.

This means our clients have the confidence of knowing all aspects of the process are taken into consideration whether this is upgrading a single machine or a complete production line.

TekPro Ltd Introducing the Holmen Range of Pellet Durability Testers exclusively British manufactured by TekPro Ltd. TekPro recently introduced the new Holmen NHP200 Series 2, the latest development of their popular benchmark setting pellet durability tester, used worldwide for quickly and easily calculating, and recording the Pellet Durability Index (PDI) of feed pellets by simulating the pellet transportation environment from mill to animal. Once a sample of pellets is loaded into the NHP200, it automatically removes any fines, weighs the sample, tests the pellets by agitating them with air, weighs the remaining sample, and calculates and displays the PDI on a colour LCD screen. This autonomous solution removes the risk of human error, creating an accurate and reliable test methodology. The reduction in human input also allows other tasks to be completed by the operator, while the test is carried out. On average, tests last around 4 minutes, with the duration automatically set by the pellet diameter selected. Suitable for pellets 3mm-12mm diameter. Features include:

Optimizing feed safety and minimizing spoilage The Hot Start Steam Mixer helps to optimize the feed safety while minimizing spoilage. Safe feed forms the basis for safe food. The Hot Start Steam Mixer helps to optimize the production of safe feed by preventing contamination of further processes by untreated product. As all product exiting the Hot Start Steam Mixer has reached the required temperature, wastage at batch start-up is prevented. Saving not only money. Also from a sustainable perspective it has become ever more important to make sure spoilage of raw materials is minimized.
