With the rapid development of the aquaculture industry, traditional breeding methods have not adapted to the needs of new economic development. The aquaculture technology is constantly updated, especially the rapid rise of flowing water fish culture, net cage fish culture, and special aquaculture. It is eagerly hoped that there will be a kind of aquatic bait that can float in the water for a long time to meet the needs of a new model of aquaculture. Aquatic feed extruder machine is gradually developed under this situation.

Whether you want to process floating fish feed or sinking fish feed, whether it is 1mm fish feed or 3mm fish feed or other sizes, our fish feed extruder euqipment or fish feed pelletizer can meet your needs.
In recent years, the aquaculture industry has developed rapidly, and the key to aquaculture is to provide various forms of feed that can meet the nutritional feeding habits of aquatic animals. Here are three types of sinking (middle and lower fish) and sinking (river crabs, shrimps), and they can be kept in the water for a certain period of time so that the animals have enough time to eat.
Using the extrusion technology of fish food extruder , various types of subsidence can be produced, which is difficult to achieve with other fish feed manufacturing technologies. Therefore, the emergence of fish feed extruder machine solves this problem well.
Currently, the main fish feed machine applied in aquatic feed production is single screw fish feed extruder which is also divided into dry type fish feed extruder and wet type fish feed extruder machine. With different parameters and feed formulation, fish farmers and fish feed mills can make floating, sinking and slow-sinking feed with high quality and nutrition so as to adapt for diverse ingestion requirements of various aquatic animals. Adopting alloy steel as material。
1.Biaxial machine differential conditioning: effects of aging particularly good tone quality, increase water vapor in the process of completely soaked and set the raw materials powder uniform ripening, the same time added to fish oil, lecithin ,fish soluble ,etc.
2.The basic function of fish feed produced through fish feed machine extrusion process is to kill the germ, mycete and fungus in feed ingredients, improve the hygienic quality and provide safe fodder for fish and other aquatic animals.
3.High digestive utilization ratio: in the extruding process of fish feed extruder machine, the heat, steam, pressure and other mechanical actions can promote the degree of starch pasting, break and soften the cell wall part of fiber structure and release some digestible materials, which is in favor of the digestion and absorption for aquatic livestock.
4.Slight pollution to environment: with good stability in water, extruded fish feed made by floating fish feed extruder machine makes it possible to decrease the dissolution and sediment of feed nutrition and then reduce loss and waste, alleviating water pollution.
5.Convenient feeding management: extruded fish feed made by the fish feed production machine can float on water for a long time, which makes it easier to observe fish ingestion so as to adjust feeding quantity timely and master fish growth and health state.
According to whether to add steam or water, the fish feed extruder machine can be divided into two types: dry type fish feed extruder and wet type; according to the extrusion method, the floating fish feed extruder machine can be divided into two types: single screw fish feed extruder machine for fish and double shaft floating fish feed extruder machine.
The wet fish food extruder is an additional steam regulator on the basis of the dry extruder machine for fish feed. The material is subjected to steam pretreatment before expansion. This processing method increases the fish food extruder machine cost, but also increases the productivity and prolongs the damage. The service life of the parts helps to volatilize and remove the peculiar smell of the feed.
In the process of extruding, the DSP fish extruder machine adopts the heat from friction for warming materials, forces materials to pass through die hole and gets certain pressure simultaneously under the action of screw extrusion. After extruding out of die hole, materials pressure will decrease sharply and moisture will evaporate so as to achieve the goal of extrusion.

After starch is puffed, its physical structure undergoes gelatinization and decomposition changes. Gelatinization can improve the digestibility of starch. The digestibility of immature corn (mainly starch material), channel catfish and Nile tilapia can only reach 26% and 45%, respectively, but it can be used for matured corn, reached 58% and 72% respectively.
Puffed products made by fish feed extruder machine are loose and porous, with controllable density. This feature is most suitable for the requirements of aquatic feed, and its density can be adjusted to adapt to the requirements of a variety of feeding objects and different feeding environments.
Extruded floating feed made by fish feed extruder machine has good stability in water and can generally be maintained in water for 2 hours without collapsing, so it can reduce the dissolution, loss and precipitation of nutrients in the feed. The use of extruded floating feed can generally save 5%-10% compared to powder or pellet feed, and reduce water pollution.
During the extrusion process of fish feed extruder, the maximum temperature of the material can reach 130-160℃, and the time is about 5-10$eC. High temperature can kill pathogenic bacteria, improve sanitation indicators, and inactivate various harmful factors and enzymes, so that some unconventional protein resources and a large amount of agricultural and sideline products leftovers are turned into treasures, which broadens the use of feed materials.
The range of choices improves the quality of feed. In addition, most eel and turtle feeds currently use a large amount of monostarch to make the feed have a certain cohesiveness. The fish feed extruder machine puffing can make ordinary corn and flour starch, which can reduce costs and provide a part of energy for fish.
The traditional feeding method for carnivorous fish is to feed bait fish. When fresh fish cannot be caught in typhoons, body fishing, etc., the fish feed becomes a big problem. The fish feed extruder machine puffing process can make fish meal content up to 60%. The above feed is used to replace chilled fish and shrimp, which can not only meet the nutritional needs of fish, but also reduce the pressure on live bait and is not affected by the weather. It can be supplied all year round.
