The working principle of the feed extruder is to puff, expand and rupture the feed raw materials in an instant through high temperature, high pressure and violent extrusion, thus changing its physical and chemical properties. The puffing process can change the structure and composition of the feed, increase the solubility of starch in the feed, make the protein easier to digest and absorb, and reduce the content of anti-nutritional factors, thus improving the nutritional value of the feed.

This is a newly designed processing technology for improving the dog food, floating fish balls market, successfully developed with our many years of research experience in machinery. This dog food making machine gives pet food novel shapes, unique flavors and colors. It can meet other needs of the modern market through many superior features, such as scientific nutritional formula and easy assimilation. This kind of food making machine can also make pet food with core fillings, which will be more popular with modern pets.

Feed extruder usually consists of the following parts

Feeding system: used to transport feed ingredients into the extruder, usually using a screw conveyor or vibrating feeder.

Puffing chamber: The puffing chamber is the core part of the puffing machine and consists of a spirally arranged extrusion roller and a cavity. The feed raw materials are puffed and expanded by high temperature, high pressure and screw extrusion in the expansion chamber.

Heating system: In order to realize the expansion process, the feed extruder is equipped with a heating system, which usually uses steam or electric heating to increase the temperature in the expansion chamber so that the feed raw materials can be fully heated.

Discharging system: After the expansion process is completed, the expanded feed is discharged through the discharging system, usually through a vibrating discharge machine or conveyor belt.

Feed extruder plays an important role in the feed processing industry, and is especially suitable for processing animal feed such as livestock and poultry. Through the puffing process, the taste and nutritional value of the feed are significantly improved, which can improve the growth rate of animals and the utilization rate of feed, while reducing the waste of feed, and has good economic benefits.

Fish feed extruder

The fish feed extruder is a newly designed processing equipment based on our many years of food machinery research experience to improve the dog food and floating fish ball markets. This extruder can also produce pet food with novel shapes, unique tastes and bright colors. It also has many superior properties such as scientific nutritional formula and easy digestion and absorption, and can meet other needs of the modern market. Moreover, this dog food extruder can also make cored fillings for pet food, which will be more conducive to pet absorption.

Machine features

1) The spiral sleeve uses 40 Cr as material, which has high hardness and good durability.

2) The sleeve consists of two layers: an inner sleeve and an outer sleeve. If wear occurs, customers only need to replace the inner sleeve, saving maintenance costs.

3) Both the raw material feeding motor and the feed pelletizing motor are adjustable speed motors, and customers can adjust the feeding speed and final pellet shape as needed.

4) The machine is equipped with a temperature controller that can control the temperature of the machine. Temperature control is the main factor in making fish food pellets.

5) This machine is equipped with a large hopper, which can load feed well.

6) The machine is equipped with an electric control cabinet, so customers can control the machine conveniently.

Application of fish feed pellet machine

1. We can provide various shapes of high-end pellet feed for fish, shrimp, etc. according to different requirements.

2. The finished particles can remain floating for 12 hours without polluting the water quality.

3. The floating time can be controlled by adjusting the puffing degree

4. The floating feed extruder for pet feed can extrude particles with a diameter of 1mm-12mm by simply changing the mold.

5. The use of electric heating device can improve the feed expansion rate and particle floating time.

6. The high-temperature and high-pressure cooking process kills salmonella and bacterial infections and makes the particles easy to digest.

7. The cutting device can be adjusted to make particles of different lengths.

8. Wet machines require a boiler to create steam and conduct the steam to the regulator to mature the raw materials in advance.

Final product features

1) Pellets can float on the water for at least 12 hours.

2) The diameter of feed particles is 0.9-8mm, and the length is adjustable.

3) The particles are smooth and nutritious.
