The cow manure organic fertilizer production line refers to a series of processes that convert fresh or dry cow manure into high-quality organic fertilizers. This process involves multiple steps aimed at fully utilizing the nutrients in cow manure while removing potential harmful substances, as shown below:
1. Preliminary preparation
Collection and storage: Firstly, collect cow manure, usually fresh or dried cow manure after solid-liquid separation.
Mixed raw materials: If necessary, other organic waste such as straw, sawdust, chicken manure, etc. can be added to adjust the carbon nitrogen ratio for subsequent fermentation.
2. Fermentation pretreatment
Composting fermentation: This is the most critical step, where the mixture is stacked in strips or flipped for fermentation, promoting microbial activity, high-temperature sterilization and disinfection, decomposing organic matter, and generating heat. The temperature can reach 50 ° C to 70 ° C.
Pile flipping ventilation: Regularly flip the pile to ensure sufficient oxygen, accelerate the fermentation process, and avoid adverse reactions under anaerobic conditions.
3. Drying and screening
Drying: The fermented material is dried by air drying or mechanical drying to reduce its moisture content to an appropriate level for storage and granulation.
Screening: Remove large impurities to ensure uniform and consistent particle size in the finished product.
4. Add auxiliary materials and mix well
Microbial agents, mineral elements, or other additives can be added and mixed in specific proportions to enrich the nutritional value of fertilizers.
5. Granulation molding
By squeezing, rotating, and pressing the mixture into particles, it is easy to package and sell.
6. Cooling and packaging
The particles are cooled to prevent excessive moisture and maintain stability.
Finally, use a packaging machine to seal the bags, label them, and prepare for shipment.
7. Quality inspection
Strict quality inspection procedures are implemented throughout the entire process of processing fertilizers on the organic fertilizer production line to ensure that the products meet industry standards and meet customer needs.
The specific process and equipment configuration for each step may vary depending on the production scale, raw material characteristics, and expected output. Modern organic fertilizer production lines typically integrate automated control systems, which improve efficiency, reduce labor costs, and ensure consistent product quality.
