With the increasing demand for aquaculture industry in modern society, the development of fish feed processing machines is also becoming more and more mature. Fish feed processing machine refers to the process of mechanically crushing, mixing, granulating, drying, seasoning and other processes of different feed raw materials, ultimately producing feed suitable for different types of fish.
1, Granular feed machines include single screw extruders and twin-screw extruders
The pellet feed machine is mainly suitable for producing cylindrical pellet feed with a diameter between 1-12 millimeters. The production process is roughly divided into several steps, including crushing, mixing, granulation, cooling, seasoning, screening, etc. During the production process, indicators such as feed taste, calories, and texture can be adjusted according to the characteristics and needs of different fish species. The pellet fish feed machine is mainly suitable for feeding carnivorous fish and freshwater fish, such as carp, grass carp, crucian carp, catfish, salmon, etc.
2, Crushed feed machine
The feed pulverizer is mainly suitable for pulverizing different feed materials, which can pulverize weeds, corn, soybean meal, bones, etc. into powder form, facilitating subsequent mixing and processing. The shredder is suitable for feeding herbivorous fish and small carnivorous fish, such as grass carp, salmon, sardine, etc.
3, Mixed feed machine
The mixed feed machine is mainly suitable for mixing different feed materials after crushing. The operation process is roughly as follows: crushing raw materials → weighing → stirring and mixing → adjusting with water → steaming and boiling, ultimately producing feed with different flavors and balanced nutrition. The mixed feed machine is suitable for feeding carnivorous fish and freshwater fish, such as tiger fish, carp, catfish, etc.
4, Granulator
Granulators are mainly suitable for producing feed pellets of various shapes and sizes, mainly through processes such as extrusion, grinding, and screening. The feed particles produced by the granulator have high stability and controllability in terms of size, taste, and calorific value, which are suitable for the characteristics and needs of different fish species. The granulator is suitable for feeding various carnivorous fish, herbivorous fish, and small fish, such as snapper, trout, crucian carp, carp, yellow croaker, etc.
5, Egg beater
Egg beater is a device dedicated to making fish egg feed. The general operation process is as follows: make fish paste → add seasonings such as starch, salt, monosodium glutamate, spices, etc. → stir evenly → make fish eggs into spherical or other shapes according to their size → steam and cool. Egg beaters are mainly suitable for feeding carnivorous fish and freshwater fish, such as eels, tilapia, blackfish, etc.
In summary, different types of fish feed processing machines have their own production characteristics and advantages for different fish and feed materials. Professional fish feed manufacturers often choose twin-screw fish feed extruders to produce fish feed, considering various factors such as physics, chemistry, and nutrition that need to be considered in the feed production process. Choosing a suitable fish feed processing machine is the key to improving production efficiency, quality, and economic benefits.
