Xj-115 Hot Feed Rubber Extruder
|Place of Origin:|
Fish feed extruder,also called fish feed pellet mill,is widely used for producing variety materials into high-grade aquctic feed pellets for fish,catfish,shrimps,crab etc.The final feed pellets have unique shape and good taste,high nutrition and smooth textures.For feeds of fish and shrimp,the floating time no water surface can be adjusted by the extrusion degree adjustment when extruding the pellets.Currently,floating fish feed extruder has become an ideal for small and medium fish farm(catfish,tilapia,shrimp etc.)
Pellet mill is mainly composed of three parts : the feeder, the transmission mechanism conditioner and the pelletize system.
The condition system stirs the powder, the molasses and the steam together and then put the powder material to the pellet mill from the feeding conditioner. At this time the powder material has been seed to the clearance between the die and the compression roller and been compressed strongly by the affect of the die . The columned pellet feed has been discharge from the dies and has been cut off by the cutting knife outside the dies.
In order to improve the effect of feed ripening, the pellet mill often installed 2 or 3 conditioner, and three conditioner should be used to produce shrimp feed and fish feed, in order to increase the soaking time (water resistance) of feed particles in water for 2 to 5 hours, so as to facilitate fish and shrimp feeding without wasting feed and not polluting water quality.
