Under high-temperature weather conditions, organic fertilizer production lines can control moisture and temperature in the following ways to avoid foul odors:
Moisture control and raw material pretreatment: Before fermentation, the moisture content of raw materials such as livestock and poultry manure should be controlled at 40% to 65%. Moisture can be regulated by adding dry materials such as straw and sawdust.
2. During the fermentation process: Keep the moisture content of the fermentation materials between 50% and 60%, which is the optimal humidity range for microbial activity. The moisture can be regulated by regularly turning the pile and spraying water.
3. Drying process: During the drying stage, ensure that the moisture content of the material is reduced to below 20%.
4. Temperature control: The temperature should be gradually increased and maintained between 50℃ and 65℃. If the temperature rises too quickly, the ventilation volume can be appropriately reduced. When the temperature of the pile exceeds 65℃, it is necessary to turn the pile in time to prevent excessive decomposition of organic matter and the production of foul odors. In the later stage of fermentation, the temperature should be gradually reduced and maintained at around 40℃.
5. Optimize the fermentation process: Adopt aerobic fermentation technology, and ensure oxygen supply through forced ventilation and regular turning of the pile.
6. Add deodorant: During the fermentation process of organic fertilizer fermentation equipment, adding an appropriate amount of deodorant, such as biological deodorant or activated carbon, can effectively reduce the foul smell.
7. Sealed storage: Organic waste should be stored in a sealed manner to prevent the spread of odors.
Through the above measures, the moisture and temperature of the organic fertilizer production line in high-temperature weather can be effectively controlled, the generation of foul odors can be reduced, and production efficiency and product quality can be improved.
