diesel engine fish feed machine electric start diesel fish feed extruder
For making fish pellets, most of people will pick floating fish feed pellet mill. As the fish feed pellets floating on 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.
Diesel engine fish feed extruder is driven by a diesel engine and operates on this basis.Our factory provides a variety of die plates with 0.9-15mm aperture, which can extrude more than 30 kinds of common feed pellets. The capacity is from 30 kg/h to two tons per hour. In addition, we also provide the best compression ratio of the die plate, so that each of the particles you made is smooth, uniform and glossy. The structural design of this diesel engine fish feed extruder machine is scientific and reasonable, with small floor area and low noise, high output and low energy consumption. The molding rate of the particles is high and the surface is bright and clean, which is good for storage and transportation. The operation and maintenance of this equipment is simple, safe and reliable.and it is widely preferred by small or medium fish farms and fish feed production plants. It is used to process various grain materials into high-grade aquatic pellet feed for fishes, dogs, tortoise, frogs, shrimps and crabs, etc. The fish feed extruder machine has different die moulds, and so the pellet size is adjustable according to your production needs. We also supply the diesel engine fish feed machine that fits well large-scale fish farming and fish feed production.
Working Principle of diesel engine fish feed machine
1. Tempering: After entering the extruder, the material should be tempered first. It is similar to the tempering process of the diesel engine fish feed machine, 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.
advantages of diesel engine fish feed machine
1.It solves the problem of electricity shortage and electricity not stable, and the three-phase power is not used, but the output is required.
2.A variety of die plates with 0.3-15mm aperture, which can extrude more than 30 kinds of common feed pellets.
3. Advance the frequency control system, with this system, it can produce different sizes pellets by changing the speed.
4. There are 4 kinds of molds that meet all sizes requirements. They are easily taken out and changed.
5.The regulator is connected with the boiler, the materials can be pre-steamed totally, so the quality and efficiency of the pellets are obviously improved.
6. Stable functions, it can work continuously.
