Twin screw technology for better extruded feeds

Extrusion processing can be a better alternative to produce high quality-low- polluting shrimp feeds. Extruded pellets with high water stability can be produced by controlling the Specific Mechanical Energy (SME) and without the inclusion of artificial binders. New extruders are equipped with state-of-the art SME controls that permit the adjustment of the SME to the desired range, to produce soft very hydrostable pellets.
