How to control the moisture content of feed products in winter

Control the moisture of the corn, extend the cooling time, and raise the leveler, which will not slow down the granulation speed. We use a 1:4 ring mold to make pig stocks with a capacity of 15 tons, but to reduce the water to 13 tons. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

1. Firstly control the moisture of raw materials, especially corn moisture, try not to keep the goods more than 16.0%, which is not conducive to the production process. The moisture control of the semi-finished products is mainly on the raw materials, and the corn can be pulverized to take the corn to measure the moisture, so as to see how high the moisture of the corn in use is. This is also a good way to verify the acceptance of corn. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

2. Then the production link is concerned: nvw China Feed Industry Information Network - based on feed, serving animal husbandry

A. The compression ratio of the ring membrane is as high as possible (do not affect the palatability); nvw China Feed Industry Information Network - based on feed, serving animal husbandry

B. Control the granulation speed, especially the large-aperture capacity, and pay attention to the production speed; nvw China Feed Industry Information Network - based on feed, service animal husbandry

C. The effect of the wind net. The power of the fan, the effect of Shakelong , the insulation of the wind network; nvw China Feed Industry Information Network - based on feed, serving animal husbandry

D. Ambient temperature and temperature difference of the material. The smaller the better, the longer the temperature of the finished product will be reduced. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

3. The working condition of the post-spraying equipment, whether the spray is normal, pay more attention. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

4. Pay attention to the weather produced at night, and the rainy days must strengthen the control. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

5. Materials that are difficult to control moisture are best produced at noon during the day. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

7. If your equipment is not good, then don't make it. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

8, reduce the modulation temperature, the temperature difference between winter and summer leads to the same temperature must be high in the winter. Nvw China Feed Industry Information Network - based on feed, serving animal husbandry

The key to controlling the moisture content of the finished pellets is the process of quenching and cooling. The quenching and tempering process depends to a large extent on the experience of the operator. The amount of steam added and the control of the temperature are generally controlled according to the moisture content of the powder before quenching and tempering, and the control of the quenching and tempering time should be based on the physiological period of the animal. Features to control. The cooling effect of the cooler directly affects the moisture and temperature of the finished material. The cooling time and wind speed should be controlled during the production process based on the moisture content and particle size of the pellets in the cooler.

The most critical thing for us to produce is the cooler. The problem with product moisture is first checked for the combined moisture of the raw materials, followed by the cooling system, then the quality of the steam, and finally the granulation and human factors.

In fact, the raw materials are fixed after the selection. For the producers, the general situation is that the raw materials cannot be controlled. Then the finished product moisture is naturally mainly in granulation and cooling in the production control. The steam can add 2-3% of water, and the cooling can reduce the water by 2-3%, which is almost the same. Refueling and adding water also play a role in assisting moisture in production.

I think that for powder, because there is no quenching and tempering, so as long as the moisture content of the raw materials, the temperature and humidity of the storage environment of the raw materials and finished products can be controlled; nvw China Feed Industry Information Network - based on feed, serving animal husbandry

The moisture content of the pellets should be mainly determined by the temperature, pressure and steam saturation during quenching and tempering. According to previous studies on granulation conditions, it seems that the moisture should be between 15-16.5% when tempering. In fact, it should be determined according to the composition of the raw materials and the room temperature at that time.
