Floating fish feed machine is widely used for producing grains into high-grade aquatic feed pellets for fish, catfish, shrimps, crab etc The feed pellet size can be from 0.9mm to 10mm by changing the moulds. It is suitable for making feed for small fish to big fish. Working Principle: The extruder is provided with a set of screw and screw sleeve, which have the function of mixing and kneading.
After the raw material enters the expanded cavity, the material is squeezed, frictional, shear and other effects between the screw sleeve, and the internal pressure keeps rising, up to 4Mpa, and the temperature keeps rising, up to 140 degrees Celsius.With the sharp increase of temperature and pressure within 3-7s, the material’s tissue structure changes, making starch further gelatinize, protein denaturation, crude fiber destruction, killing salmonella and other harmful bacteria.High temperature and high pressure materials come out from the outlet, the pressure is suddenly released in an instant, and part of the moisture occurs flash evaporation. After cooling, the material presents a loose and porous structure, while after expanding, the material presents a ball shape, flocculent shape or coarse debris shape.
Uses/benefits of Floating Pellet Machine:
Fish feed pellet machine adopting international advanced technology, the pellets are very even.
2. We can get the different size and length of pellet diameter ( diameter from 1mm to 8mm).
3. The electric heating device improve the feed expansion rate.
4. High temperature and high pressure can kill the salmonellosis and bacterial infections.
5. Fish feed machine can get the higher-protein animal feed, and easy to digest
Features of Floating Pellet Machine:
All fish food equipment are made of stainless steel. 2). The fish food whole line fully continuous and automatic. 3). Ding run provide basic fish food formula according to your require. 4). The final fish food shapes and sizes can be various by changing the mould. 5). Supply different size mould free of charge. 6). Packing machine could be supplied to work with the fish feed production line (depending on your require)
