Dry Type Fish Feed Extruder

Working Principle of Dry Type Fish Feed Extruder
Under the action of the frictional force of the principal axis and flat die, the compression roller spins. The high temperature between the roller and die ripens the starch of the materials, and the protein becomes congealed. Then the fish feed is extruded from the holes of the die. Fish feed pellets are conveyed out of the extruder. Additionally, we can choose the length of the feed by regulating the angle of the cutting knife.

Features of Dry Type Fish Feed Pellet Extruder
1. Simple structure, widely used, small flooring space, low noise.
2. We can use dry powder materials to make feed pellets without adding extra water to the dry-type fish feed extruder. The dry pellet feed is convenient to store.
3. The dry pellet feed is well processed which is easy for the animals to digest. During the process, the pathogenic microorganisms and parasites are eliminated.
4. These fish feed pellet extruders are also applied to make pellet feed for rabbits, ducks, and the like. What’s more, the pellet feed is more economical than the compound mash feed.
5. There are many different press molds you can choose according to the size of the pellet that you

need.
6. The raw materials that can be used in producing pellet feed are various.

Running-in of Floating Fish Feed Extruder
1. Blend 5 or 10-kilogram mash feed with edible oil of 5% or 10% together. If the mash feed becomes caking, we should disperse them to keep the feed in powder condition.
2. Put the feed into the extruder before we turn on the machine. Then we should regulate the bolt of the press roller until the feed can be extruded normally.
3. We should do test runs with the oily mash feed 3 to 5 times before adding dry powder into the machine. And the pellet which is made of oily mash feed should not be used in feeding rabbits.
4. If you want to regulate the length of the pellet, we can adjust the angle of the cutting knives.
5. Feed pellets are hot when they are just coming out of the machine. We should place them in a ventilated room. After cooling down, the feed pellets can be stored in bags.

Tips of Dry Type Fish Feed Extruder
1. Stay away from the feed inlet when the fish feed extruder works. If you want to add materials to it, you should do so with the help of a stick, not your hand.
2. We should add materials before turning on the machine. Leave some materials in the extruder when you stop the machine in case the express roller and die mold directly touch each other.
3. If the machine gets stuck, we should turn down the machine immediately.
4. We should loosen the bolt of the express roller after finishing work.
5. Check the degree of tightness of the belt to prevent the belt from slipping and decreasing its capacity.
6. Add and replace the lubricating oil regularly.
7. It is normal that the temperature of the engine rises to 70 degrees after long continuous working.
