This well attended Wenger Aquafeed Seminar took place April 25-27, with attendees from world over in the renovated Wenger Technical Center in Sabetha, Ks. was complete with lectures in a state-of-the-art presentation room coupled with demonstrations on the available extrusion, drying equipment and ancillary gear.
This 3-day seminar started with introductions followed presentations and demonstrations on all of the three days. The host of the event was Jesse Mitchell and the lecturers included Dr Anders Haubjerg who covered many topics as well as Ed de Souza, Robert Sunderland, Keith Erdley, Andrew McClaskey and Will Eisenbise.
Topics discussed in detail included Ingredients and how they related to aquafeed extrusion, Principles of Aquafeed Production, Preconditioning, Extrusion of various styles, singles twins, conical co-rotating extruders and other possibilities. Dies designs with comparisons, Salmon and Mediterranean feed production, Drying and Cooling of all types of aquafeeds, Coating, Control processes as well as Energy usages advancements and RAS feed production.
The demonstrations included making a stable sinking shrimp feed, salmon feed and floating aquatic feed with control changes making the feed sink. Having been around the block a few times what impressed me was the cleanliness of the demonstrations. The feed transportation system to the extruders, the conveying system the lack of steam escaping let alone no fines in site were a testimony to the advancements in the details needed in a major industry, the petfood industry. This has been seen many times over the years, how advancements in extrusion mingle among industries. The computer control system with its uncanny abilities allows for the precision to make such a sanitary demonstration. I do believe this is the future of what an aquatic feed plant should look like in a pilot plant form. It was clean and tidy but the point is there was nothing escaping to dirty the place up and the products were perfect.
Congratulations to the Wenger team for a fantastic Seminar on Aquafeed Production and sharing the advancements made in this arena.
