How to control the moisture content of feed products in winter
2. Production process:
A. The compression ratio of ring die should be as high as possible (Do not affect palatability).
B. Control the pelleting speed, especially the material with large aperture and large production capacity.
C. The effect of air network. The power of fan, the effect of conveyer, and the insulation of air network.
D. Temperature difference between environment and material, the smaller the better, the time of temperature dropping of finished product should be prolonged.
3. Pay attention to the spraying equipment and check if the spraying is normal.
4. Pay attention to the weather during the night production, strengthen the control during bad weather.
5. We had better produce feed with uncontrollable moisture at noon.
6.Use a modified formula if the above operation is ineffective.
7.But poor-quality equipment will seriously affect the production effect.
8. Reduce the conditioning temperature. Due to the temperature difference between winter and summer, if we want to reach the same temperature, we need higher steam volume in winter.
Conditioning and cooling are the key to control the moisture of pellet products. Conditioning depends largely on the operator's experience. The amount of steam and temperature are generally controlled according to the moisture content of powder before conditioning, while the conditioning time should be controlled according to the characteristics of the physiological period of animal. The cooling effect of cooler directly affects the moisture and temperature of finished product. In the production process, the cooling time and wind speed should be controlled according to the moisture content and particle size of the pellet feed in cooler.
As a matter of fact, raw materials are determined in advance, so the source of raw materials cannot be controlled by producers. Then the moisture content of product in the production control naturally mainly lies in pelleting and cooling. We can increase 2-3% moisture of steam, reduce 2-3% moisture of cooling to achieve a proper value. Oil and water adding also play a role in assisting moisture in production.
For powder feed, we only need to control the moisture content of raw materials, storage environment temperature and humidity of raw materials and products because there is no conditioning.
