Geelen Counterflow develops a new generation of counterflow coolers Geelen Counterflow has developed a new generation of counterflow coolers that improves product quality, operational cost and efficiency. Counterflow Cooler Plus™ allows an improved product distribution, easy inspection and optional evaporation control. The new counterflow cooler uses Evaporation Control™ to select the ideal air volume and cooling time to maximize or minimize evaporation in the cooler when feed producers are keen to avoid insufficient or excessive product moisture after cooling due to fluctuations in raw materials or ambient circumstances. Multiple sensors for air and product temperature help to control the process. Even a 0,5% improvement in the average moisture content of product can have a very significant effect on the processor’s bottom line. The company said that the new Topdrive product distributor has its gear motor mounted outside of the cooler, lowering the risk of pollution and overheating. Inspection of all moving parts of the product distributor is possible from the
outside. The short vertical drive shaft in solid stainless steel minimizes the need for horizontal surfaces inside of the cooler, keeping the process as clean as possible. The drive of the product distributor is controlled by a frequency converter to allow the corners of the cooler to be reached, leading to a very even product distribution. The new stainless steel +10% Hood design has a 10% bigger air exhaust opening which reduces airspeed to avoid product being sucked into the air exhaust system. The round flange avoids the need for a transition piece from rectangular to round and the diagonal exhaust orientation keeps dust from accumulating on any horizontal surface. The company also said that the big access doors in the side walls
and collecting hopper enable good access for inspection and cleaning. The side walls in stainless steel contain multiple product sensors to allow automatic selection of bed depth, depending on product and ambient conditions. The discharger of the cooler is a versatile swivel valve discharger, available in mild steel or stainless steel, that can handle any size, shape and condition of food, pet food, aquafeed and feed. Its hydraulic drive with angle encoder enables your control system to automatically set product specific open and close positions.
Le Gouessant Aquaculture and Innovafeed succeed in 100% fishmeal substitution with insect in rainbow trout feed Following the authorization in July 2017 to integrate insect meal in the diet of fish and shellfish, Le Gouessant, one of the major player in aquaculture nutrition in France and InnovaFeed, a French biotech company that produces a new source of protein from insect rearing for animal feed, decided to launch a
joint trial in experimental conditions on rainbow trout (Oncorhynchus mykiss). While there is an increasing number of trials using insect meal, this was the first time that 100% of the fishmeal has been substituted by high quality insect protein derived from black soldier fly larvae (Hermetia illucens).
