Introduction of Dry Type Fish Feed Pellet Mill
Food for fishes always contains rich crude protein, but the crude protein in the food is hard to digest for the fish. After being processed by the fish feed pellet mill the feed can be easy to digest. Similar with wet type fish feed pellet machine, dry type also uses alloy steel. Dry type fish fish feed pellet machine is suitable for small- or medium-scale fish farms and fish feed industry, for processing shrimp feed, prawn feed, floating fish feed, sinking fish feed pellets and pet feed pellet.
Working Principle of Dry Type Fish Feed Pellet Mill
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.
Advantages of Dry Type Fish Feed Pellet Mill
1. This fish feed pellet mill is widely used for producing floating feed pellets of all kinds of aquatic animal.
2. Advanced technology and humanized design ensures easy operation and reliable performance.
3. this fish feed pellet mill has high efficiency, low power consumption
4. Screw sleeve of this small fish food extruder adopts enchase alloy steel strip structure, which guarantees long service life.
5. Different moulds can be chosen to make pellets with different diameters and shapes.
6. final pellets produced by this fish feed pellet machine dia. Is 0.9-15mm.
The Differences between Dry Type Extruder and Wet Type Pellet Mill
1. Dry type fish feed pellet mill does not need the steam boiler, so dry type fish feed pellet machine is cheaper and easier to use and operate.
2. The feed pellet made by wet type fish feed pellet machine is more smooth and with better quality because the material is ripen and mixed enough in the conditioner compared with the dry type extruder.
3. The capacity of the dry type fish feed pellet machine is lower than the wet type fish feed pellet machine, so usually the dry type fish feed pellet machine is better and economic for the small and medium size user or factory.
Raw Material for Making Nutritional Fish Feed
☆ Rice Dust: contain about 10-14% of protein and also contain vitamin B1, B2, B6 and small quantity of enzyme.
☆ Mustard Cake: Mix maximum 40% of cake in the fish feed. But don’t use dry cake more than 20%. Mustard cake contain 30-32% protein. It also contain a high rate of fat.
☆ Wheat Chaff: contain fiber, control many types of fish diseases.
☆ Maize: contain protein, carbohydrate, fat, vitamin A and E.
☆ Cotton Seeds: contain about 54% protein. It is a better ingredients for supplementary fish feed.
☆ Fish Powder: easily digestible to fish. Fishmeal contain about 55-60% protein.
☆ Bone Powder: very necessary for building fish-bone. The ratio of calcium and magnesium in the bone dust is 2 : 1.
☆ Innards : very suitable and ideal feed for catfish. It contain 52% protein.
