Product Description

What raw materials are needed for the extruded feed machine?
Due to the physiology and eating habits of aquatic animals such as fish, shrimp, and crabs, aquatic feed must have good water resistance, low powdering rate, fine raw material fineness, and neat feed cuts. According to these requirements, the raw materials for processing aquatic puffed feed mainly include: corn, wheat bran, sub-meal, fish meal, and cakes after oil extraction from various oil crop seeds (such as soybean meal, rapeseed meal, etc.). All food processing by-products can be used as feed.
Material sample as follows:

Application of fish feed extruder machine:
Extruded feed is a kind of feed processed by an extruder. After being expanded by high temperature and high pressure, it has a certain degree of expansion and a higher taste, which can make animals better digest and absorb. Extruded feed can not only improve the nutritional value of the feed, but also improve the appetite and taste of animals.

Advantages of extruded feed:
1. Improve the nutritional value of feed
After the extruded feed is extruded under high temperature and pressure, its nutrients such as starch and protein have been decomposed and changed its structure, making it easier for animals to digest and absorb, thereby improving the nutritional value of the feed.
2. Increase the appetite of animals
The extruded feed has a good texture and aroma, making the animals more appetizing. By increasing an animal's appetite, its nutrient intake can be increased, thereby increasing production efficiency.
3. Reduce feed costs
Compared with traditional feed, extruded feed can not only improve the nutritional value of feed, but also reduce feed cost. This is why more and more farmers are beginning to use extruded feed.

Working principle of puffing machine:
The extruder has a screw and a screw sleeve, which have the functions of mixing and kneading. After the raw materials enter the expansion chamber, they are squeezed, rubbed, sheared, etc. between the screw sleeves. The internal pressure continues to rise, up to 4Mpa, and the temperature continues to rise, up to 140 degrees Celsius. Within 3-7 seconds, the temperature and pressure increase sharply, and the organizational structure of the material changes, further gelatinizing the starch, denaturing the protein, destroying the crude fiber, and killing harmful bacteria such as salmonella. When high-temperature and high-pressure materials come out of the discharge port, the pressure is suddenly released in an instant, and the water is partially flashed. After cooling, the material takes on a loose and porous structure, and the expanded material takes on the shape of lumps, flocs or coarse chips.

Structure of puffed fish feed machine:
  1. The feeder is to ensure uniform and stable feeding, and the feeding amount is adjusted according to the rated current value of the extrusion motor. --Generally, an electromagnetic speed regulating motor or frequency converter is used to adjust the speed to change the feeding amount of the feeder. The outlet of the feed hopper is usually fed by a spiral auger to the extrusion and puffing section.
2. The expansion chamber is composed of screw, screw sleeve, template, clamping bone, etc. The screw and screw sleeve are combined in sections. The compression degree can be adjusted according to the type and requirements of the puffed feed, and the puffing degree of the puffed feed can be changed.
3. The expansion mechanism is divided into 3 sections according to its function and position in terms of collapse degree: Feeding section: This section has a larger screw pitch and mainly transports and compresses the material so that the material fills the spiral groove. Compression section: The screw groove in this section changes from deep to shallow along the direction of material movement to compress the material. Extrusion section: The screw groove is shallower, the pitch gradually becomes smaller, the extrusion force can reach 3.0-10Mpa, and the temperature can reach 120-150 degrees Celsius. This section has high pressure and high temperature, so the screw and sleeve are also easy to wear. The outlet of the extrusion section is a template. The shape of the template is designed with different die holes according to the needs of different feeds. The material is extruded from the die holes of the template and enters the atmosphere. The pressure and temperature drop sharply, causing its volume to expand rapidly, and the moisture content Rapid evaporation, dehydration and solidification become puffed material.
