For making fish pellets, most of people will pick floating fish feed pellet extruder. As the fish feed pellets floating above the water is effortless to be ate via the fishes. Meanwhile, it can limit the air pollution of the fish feed. The floating fish feed pellets is puffed in the forming mildew below excessive temperature, so it is cured and handy to be digest through the fishes. Even although we call this kind pellet mill as fish feed pellet extruder, however, the pellets made by way of if can additionally be used for feeding pet and different planktons. The diameter of the remaining pellets can be 0.9-10mm as you want. It can be floating kind or sinking type. If the ratio of starch in the uncooked substances is much less than 35%, then the pellets will be sinking in the water.
Normally, the floating fish feed pellet extruder is driven by electrical motor. However, as the lackness of electric power in some place, we design the diesel engine floating fish feed extruder for our clients. It can be used in the field and without the limit of the electric.
Application of Diesel Engine Fish Feed Extruder
diesel engine floating fish feed pellet mill making machine produces of floating fish feed, sinking fish feed, floating shrimp feed, sinking shrimp feed, crab feed and pet feed. The produced feed is suitable for cat, dog, pig, bird, fish, shrimp, and other aquatic animals.
And the diesel fish feed machine is suitable for small, medium family production, and large professional feed processing plant.
1. Tempering: After entering the extruder, the material should be tempered first. It is similar to the tempering process of the feed pellet mill, which is both humidified and heated to the material. The purpose of the quenching and tempering is to increase the heat and humidity of the material so as to facilitate the rapid ripening of the material during the subsequent extrusion.
2. Extruding: After tempering, material get into the screw conveyor extrusion cavity, the shape of the extrusion chamber is gradually smaller along the direction of the material. The pressure of the material is increasing during the movement, while the material in the screw conveyor extrusion cavity accompanied by strong shear, kneading and friction, the temperature of the material increased sharply.
3. Swelling: When the material reaches the outlet of the screw conveyor extrusion cavity, the pressure is the largest. After squeezing out the extrusion chamber, the pressure suddenly disappears, and at the same time, the heat and moisture lose quickly, which makes the volume of the material increase rapidly and expand.
4. Cutting: The extruded material is cut into required size when it is accumulated to a certain length.
