Floating fish feed procesing machine
This is a floating fish feed making machine, its working principle is that the fish feed raw material enters the screw extrusion cavity, Under the action of extrusion, friction and shearing between the rod and screw sleeves, the internal pressure and temperature are continuously increased, and the starch in the fish feed raw material will be gelatinized. When the fish feed raw material comes out of the discharge port, its pressure is suddenly released in an instant, the water also evaporates a lot, the temperature also drops instantly, the fish feed raw material expands and condenses immediately, and there are many micropores in the condensed colloidal material, forming an extruded feed. The continuously extruded columnar or sheet puffed products also need to be cut by a rotary cutter and then cooled, and sometimes post-processing procedures such as drying and spraying additives (such as oils, vitamins, etc.) are required.
