The operation process of cow manure organic fertilizer production line involves a number of key steps, as follows:

1. Raw material pretreatment: First of all, the cow manure is pre-treated, including screening and crushing steps to ensure the uniformity of the material. Fermentation process: The pre-treated cow manure is mixed with microbial fermentation agent to carry out aerobic fermentation. In this process, it is necessary to reasonably control temperature, humidity and ventilation to accelerate the decomposition of organic matter and eliminate harmful substances.

2. Crushing and screening: The materials after fermentation need to be further crushed and screened to meet the needs of subsequent production. This step directly affects production efficiency and product uniformity.

3. Mixing and granulation: the material after grinding and screening is mixed with inorganic fertilizer and other additives in a certain proportion, and then granulated by organic fertilizer granulator.

4. Drying and cooling: the fertilizer after granulation is removed by the dryer to ensure the storage stability of the fertilizer. The subsequent cooling process ensures the quality and safety of the fertilizer.

5. Packaging: Through automatic organic fertilizer equipment to produce organic fertilizer packaging, improve production efficiency, reduce labor intensity.

6. Fermentation stacking: The fermentation stacking machine is used to turn the fermentation materials to provide oxygen for continuous aerobic fermentation, so that the fermentation materials can be quickly decomposed, sterilized, deodorized and dehydrated.

7. Storage of finished products: Organic fertilizers treated through the above steps are screened and packaged, and qualified products are stored in storage and ready for sale.

Through the above process, the cow manure organic fertilizer production line can convert cow manure into valuable organic fertilizer, realize the recycling of resources, and improve agricultural production efficiency and economic benefits.
