Fish Feed Extruder And Expander For Aquatic Feed Pellet Production
Extrusion processing technology has become of major importance in the aquatic feed pellet production line of modern feeds used in intensive aquaculture. Fish feed extruder is the prominent machine applied in aquafeed production, where the feed is subject to mixing, shearing and heating under high pressure before the extrudate finally is forced through a die. In recent years , there has been a constant growth in the application of extruded diets for aquatic feeding. Aquatic feed by extrusion have superior water stability, better floating property and a higher energy than pelleted diets, which contributes to the increase in fish growth and improvement in feed conversion. Therefore compared with the conventional pelleting process, extrusion technology is the most efficient way to improve the performance of aquatic feed. Extrusion A nd Expansion Process Extrusion, including dry extrusion and wet extrusion, is the process where the raw material is pushed forwa...
