Motor/Diesel Engine Type Fish Feed Extruder Machine Floating Pellet Fish Feed Mill

As a key equipment, fish feed extruder machine plays an important role in the aquaculture industry.

Working principle and process:

The fish feed extruder machine adopts advanced puffing technology, which processes feed under high temperature and pressure to puff, sterilize, and digest, making it easier for fish to absorb. It mainly consists of screws, feeding systems, expansion chambers, and cutting devices.

During the working process, the feed enters the extruder through the feeding system, and is subject to the high-speed rotation of the screw and the high temperature and pressure environment. After being exposed to high temperature for a short time, the starch in the feed is gel, the protein is denatured, and the cellulose becomes more digestible. Next, after passing through the expansion chamber, the feed is rapidly expanded and forms granular feed under the action of the cutting device. Finally, through the cooling device, the feed is solidified, cooled, and the required product is obtained.

Application and Advantages:

1. Improving feed solubility: During the puffing process, the structure of starch and protein in the feed changes, making it easier to hydrolyze and absorb. This not only improves the feed digestibility of fish, but also reduces waste and improves the efficiency of fish in utilizing nutrients.

2. Sterilization and pest control: The high-temperature and high-pressure environment has a bactericidal and pest control effect on bacteria and parasites in feed, effectively preventing the spread and occurrence of diseases.

3. Promoting fish growth: The puffed feed has a softer texture, making it easier for fish to chew and swallow, which is beneficial for increasing their food intake and growth and development.

4. Reduce feed costs: Expanded feed has high feed value and nutritional value, and has a high absorption and utilization rate for fish, which can reduce feed usage and reduce breeding costs.

Technical Parameters:

The fish feed extruder machine has motor and diesel engine driven two types, we can offer different driven according to the customer’s requirements.
