In the operation of cow manure organic fertilizer production line, you need to pay attention to the following skills:

1. Raw material treatment: The cow manure is preliminarily treated, including particle crushing, impurity removal and water content adjustment. Ensure the uniformity of raw materials and appropriate moisture content, which is conducive to subsequent fermentation treatment.

2. Fermentation and composting: Pile the processed cow manure into the fermentation and composting equipment, pay attention to control the height and ventilation of the composting, and avoid the situation of hypoxia or uneven heating during the fermentation process.

3. Fermentation management: Regularly turn over and ventilate the fermentation pile to promote oxygen supply and heat release in the fermentation process, and accelerate the degradation and maturation of organic materials.

4. Adjust the ratio: According to the nutrient content of cow manure and the needs of crops, reasonably adjust the ratio and formula of organic fertilizer to improve the nutritional value and fertilization effect of organic fertilizer.

5. Drying treatment: the fermentation of mature organic fertilizer is dried to reduce the moisture content and improve the quality and shelf life of organic fertilizer.

6. Packaging and storage: Package and store dried organic fertilizers, pay attention to moisture and sun protection, and ensure the quality and long-term preservation of organic fertilizers.

7. Equipment maintenance: clean and maintain the organic fertilizer equipment regularly to maintain the normal operation of the equipment and extend the service life of the equipment. The above are some of the skills that need to be paid attention to when operating cow manure organic fertilizer production line. Comprehensive consideration of raw material treatment, fermentation management, drying treatment and equipment maintenance can improve the production efficiency and quality of organic fertilizer.
