The process of fermenting sheep manure into organic fertilizer by organic fertilizer equipment mainly includes the following key steps:
Raw material pretreatment:
Raw material collection: Collect fresh sheep manure to ensure no pollution and avoid impurities such as plastic and metal.
Raw material crushing: Use a crusher to crush sheep manure to increase its surface area and promote microbial decomposition.
Preparation before fermentation:
Adjusting moisture: Based on the initial moisture content of sheep manure, add water appropriately to achieve a level suitable for microbial activity, usually maintaining a moisture content of 50% -60%.
Adjusting the carbon to nitrogen ratio: By adding carbon source substances such as straw and sawdust, the carbon to nitrogen ratio of sheep manure can be adjusted. The recommended carbon to nitrogen ratio is generally 25:1 to 30:1.
Microbial inoculation (optional): To accelerate the fermentation process, specific microbial agents can be added, which can promote the decomposition and transformation of organic matter..jpg)
Fermentation process:
Composting production: The processed sheep manure is piled up in piles, and the size of the compost can be adjusted according to the actual situation, but sufficient space should be ensured for flipping.
Temperature control: Keep the temperature of compost at 50-70 ℃, which is the temperature range for vigorous microbial activity.
Regular flipping: Regularly (usually every 2-3 days) flipping is carried out to maintain the oxygen supply inside the compost and promote the uniform distribution of microorganisms.
Monitoring the fermentation process: Observing the color, odor, and temperature changes of compost are important indicators for judging the fermentation process.
After ripening and screening:
Post ripening: When the temperature of the compost begins to decrease and remains below 50 ℃, it indicates that the fermentation process is nearing its end.
Screening: Use a screening machine to remove incompletely decomposed large blocks of material and impurities, and obtain relatively pure organic fertilizer.
Packaging and storage:
Packaging: Use an organic fertilizer packaging machine to package the screened organic fertilizer, using breathable packaging materials such as woven bags.
Storage: Store in a cool and dry place, avoiding direct sunlight and soaking in rainwater to maintain its quality.
quality testing:
Conduct quality inspections on finished organic fertilizers, including nutrient content, pH value, heavy metal content, etc., to ensure they meet agricultural usage standards.
The organic fertilizer equipment achieves efficient conversion of sheep manure into organic fertilizer through automated control and precise process flow, not only improving production efficiency but also ensuring the stability of product quality. In practical operation, appropriate adjustments and optimizations should be made based on the specific characteristics of raw materials, environmental conditions, and production needs.
