Research & Product Development



              Where food extrusion ideas become reality.


The Wenger Technical Center is a complete agrifood laboratory with pilot and production scale extrusion cooking and drying systems for researching and testing ideas, developing new products, and learning production techniques. Wenger Technical Center professionals have the knowledge and skill to help you develop, test, analyze, and produce new product prototypes and develop processes that enable new product manufacturing at full scale.

​In most cases, Wenger can help you navigate your way through the development process faster than you could do it alone - allowing you to get your concept to the market ahead of your competition.
