The wet-process fish feed extruder can be used to produce both floating fish feed and sinking fish feed. It is necessary to adjust the formula of fish feed for production. The output of the wet fish feed extruder is higher, and the wet fish feed extruder is equipped with a boiler, which can continuously supply hot steam to the screw during the fish feed production process, and the produced feed has higher maturity, smoother particles, and product quality. It is also better, and it is the first choice for large and medium-sized feed processing plants and farms. Wet fish feed extruders are also widely used in fish feed production lines.

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.

Fish Feed Machines and Floating Feed Production Line

If the given food is too big or too small, fish will not eat it. Fish feed pellets production process. On density (specific weight) depends if pellet will float on surface of water or will sink. Floating pellets have the specific weight about 450-550 g/dm3, and sinking pellets – 550-650 g/dm3.
