Product introduction

DGP dry type extruder mill is used to process various kinds of grains into high-grade aquatic feed pellets for fish, crab, catfish, shrimps, etc. This dry type fish feed pellet extruder mill has gained popularity in fish farmers. This dry type fish farm feed pellet extruder is suitable for small and medium aquaculture farm or feed pellets processing plant. Compared with buying fish feed, making your own fish feed pellets by the fish farm feed pellet extruder is really cost effective.

This dry type fish feed extruder mill can also be widely used to produce pet foods for dogs, cats, fish, shrimp, fox, etc, which includes various configurations to satisfy different output requirements. Dry type fish feed extruder is able to produce popular pet foods with novelty shape, unique taste, great nutritive value and exquisite character to satisfy different taste of pets. The fish feed extruder machine is used to make the pellet from the grain,the soybean,the cereal,or other materials.The pellet floats on the water at least about 12 hours.Especially for aquaculture industry such as the fish,the shrimptortoise,and other aquatic product.


Product advantages

1.Feed pellets produced by this dry type fish feed extruder are of puffing type, thus making it more easily to digest for fishes.

2.Final processed fish feed pellets from dry type fish feed extruder have unique taste and high nutritious.

3.The dry type fish feed extruder has high wear resistant degree and long service time.

4.This dry type fish feed extruder has advantage of low energy cost, high capacity, easy to maintain.

5.The dry type fish feed extruder novel design, high output and stable performance.

6.This dry type fish feed extruder is suitable for small fish feed pellet plant and professional farmers.

7.Main parts of dry type fish feed extruder are made of special alloy material after heat treatment.

8.Diameters and shapes of fish pellets can be adjusted by choosing different molds.

9.Salmonellas and bacterial infections can be killed by high temperature and high pressure process.

Working Principle

There is no need to heat outside the dry type machine, through the screw extruding of the raw material, heat is produced and gathered during the rotary working process in the airtight environment, and during the high temperature ripening process, the starch and fiber of the raw material become swell. Then under the pressure-tight condition, material will be formed into pellets by shaping mould. At the end, through the high pressure produced by the regular rotating of the screw, after being cut by the forepart cutter which rotates regularly and high-speedily, the finished products will be shrunk and become small average puffed balls in room temperature and pressure.

Puffing Process

The puffing process includes the following steps:

♦ The mixed feed materials are fed into the fish feed extruder;

♦ The screw presses the material;

♦ Turning screw in the barrel causes a thermal energy (temperature is 110-130 °C);

♦ Finally, we have cooked and well treated fish feed pellets.

Benefits of Puffed Fish Feed Pellets

1. From the fish feed extruder, feed pellets are in 'popcorn' state, not only physical state has been changed, but also shape and internal structure of organic molecules has been changed, which make feed pellets easier to digest and absorb for fish.

2. After treatment of puffing, fragrance and palatability of the feed has been improved to stimulate appetite of animal.

3. High temperature and high pressure process can kill the salmonellosis and bacterial infections and makes the pellets Hygeian for fish.

4. The puffed fish feed pellets can float on the water surface without dissolution for over 12 hours, reduce feed waste and keep the water quality.


  1. Make high-grade aquatic feed pellets for fish, catfish, shrimps, crab etc.
  2. Ideal for making pet food for dogs, cats, etc.
  3. First choice of fish feed pellets manufacturers.
  4. If you have fish ponds and aquatic farms, this machine is really cost-effective compared with buying expensive pellets.
