Versatile twin screw extruder ideal for aquafeed

The aquafeed manufacturing industry is widely recognised as one of the fastest expanding agricultural industries in the world. Fish meal is the main protein source in aquafeed, but supply is limited, which means that alternative sources need to be used. From a processing point of view extrusion is the most efficient way of turning plant protein into fish feed. Twin screw extruders have a definite advantage in this. In this article we have a closer look at corotating twin screw extruders.
