Floating fish feed extruder machine is a kind of fish feed pellet machinery ,it is suitable for small and medium feed process factory and aquaculture farm. It can produce high-grade feed pellets which is suitable variety aquatic ,such as fish, catfish, crab, shrimps,cat,dog etc.Single screw extruder is much cheaper price and easy operation than twin screw extruder.
During the extrusion process, raw materials would be processed via high temperature, high moisture and high pressure, so at the moment that feed pellets are extruded from die hole, the stress drops sharply and the water content in feed emits from liquid state to gas state, resulting in extruded fish feed.Fish feed production requires higher degree of gelatinization and water stability, starch gelatinization can kill salmonella and other various harmful bacteria,also strengthen adhesive property of feed pellets under high temperature , which ensure that pellets with smooth and clean appearance are not easy to be eroded by water.It’s not only promotes the water stability of fish feed but also improves the palatability and digestibility of feed. Moreover, the usage of floating fish feed extruder machine can make sure fish and shrimp have longer ingestion time, and prevent water pollution caused by feed pellets.
