A fish feed machine is specialized equipment used to produce feed pellets for fish in aquaculture. It ensures consistent quality and nutritional balance by combining raw materials like corn, rice bran, soybean meal, fish meal, and vitamins into uniform pellets. There are two main types of fish feed machines: dry type and wet type. The dry type does not require a steam boiler, making it more suitable for small to medium-scale operations, while the wet type uses steam and is ideal for large-scale production due to its higher capacity and efficiency.
The process involves grinding raw materials, mixing them uniformly, and then extruding them into pellets using high pressure and temperature. The extruder shapes the pellets and allows for customization of size and buoyancy, depending on whether floating or sinking feed is needed. The final pellets are cooled, dried, and packaged.
Fish feed machines can be powered by electricity or diesel and come in various capacities, typically ranging from 50 kg/h to over 2 tons/h. These machines improve feed conversion ratios, reduce feed wastage, and help ensure healthy fish growth, making them essential in modern aquaculture operations.
