Shrimp feed plant

First of all, workers need to put the raw materials into the feeding port, where we are equipped with a centralized dust removal device, which can help to improve the operating environment of the factory and reduce the dust generated during the production process. Then, the raw material enters into the batching silo through bucket elevator, in the middle of which the raw material needs to be cleaned by the cleaning equipment first, to reduce the possible stones and impurities in the raw material, so as to avoid damaging the machine and increasing the cost of the equipment. This is of course what we do not want to see, so we have to do a good job of cleaning in advance.

RICHI design to be crushed bin above and below the level device, can be stored in the bin of raw materials to display the storage capacity, showing the bin empty and full state. Below the bin is a dosage scale, which is computerized for accurate dosage. Each batch of mixed raw materials will enter into the mixer through the bucket elevator for mixing, of course, before the material enters into the mixer。

Each batch of mixed materials directly into the water drop pulverizer for a pulverization, pulverizer equipped with frequency feeder, customers can adjust the feeding speed according to their needs, so that the pulverizer to meet the needs of users to maximize the efficiency of the work performance. Crushed material has a negative pressure air system and fall into the settling room, and then transported by the conveyor equipment to the second crushing to be crushed bin.

 The materials need crushing in the pre-crushing bins enter into the crushing section for crushing. The main machine in this section is single-shaft paddle mixer, which adopts double-layer rotor design, and its mixing uniformity can reach up to 97.7% with short mixing time.

As the shrimp itself is relatively small, the stomach is also relatively small, in order to improve the digestibility of shrimp feed, we have to make the raw materials as much as possible to crush the finer the better, the finer the raw materials crushed, the mixing uniformity is also higher, shrimp feed particles are also more easily absorbed by the shrimp digestion.

So in order to meet the shrimp feed on the fineness of raw material crushing, this shrimp feed plant is equipped with two crushing section, two crusher. After the first crushing, the raw materials are crushed again by the water drop type pulverizer.

After the second pulverization, the raw material enters the mixer for the second mixing. The next step is the mixing of fats and oils with the pre-mixed and pulverized raw materials. The customzers can adjust these according to the specific recipe.

When all the raw materials, fats, oils and premixes have been mixed according to the recipe, the most anticipated part of the process is pelletizing! The raw materials enter the prawn feed manufacturing machine through conveyor equipment. The material passes through the feeder and enters into the conditioner. After three layers of conditioner, the starch in the raw material pasturized, and the raw material becomes mature, which is easier to be digested and absorbed by the animals. Inside the pelleting chamber, through the extrusion of the ring die and the press rollers, the material is converted into shrimp feed pellets, which are extruded from the die holes.
The cooked pellets cannot be used for packing immediately, because the temperature and humidity of the pellets are very high at this time, and they need to be cooled to avoid surface breakage. After cooling, if the size of shrimp feed pellets needed is relatively small, shrimp feed pellets can be put into the shrimp feed crumbler for crumbling.

Already here the customzer has made shrimp feed pellets. But in the granulation process will inevitably appear unqualified feed pellets, so after cooling shrimp feed pellets need screening. This time the need to use the equipment is a vibrating screen, which can divide the shrimp feed pellets into three parts, suitable shrimp feed pellets from the middle outflow into the finish goods bin.

The customer can directly pack the qualified shrimp feed pellets into the finished product warehouse. Small pellets and crushed materials enter into the crusher for crushing, and loaded into the prawn feed making machine for secondary pelletizing. At this time, it is necessary to mention the high square screen, which can screen smaller size shrimp feed pellets, that is, the shrimp feed pellets crumbled by the shrimp feed crumbler. Once you have ensured that you have shrimp feed pellets that meet your requirements, you can pack the finished product with a packing machine.
