The organic fertilizer production line that converts cow manure into fertilizer typically follows a standardized process aimed at ensuring safe and efficient conversion of cow manure into high-quality organic fertilizer. The following is a typical production process flow:
1. Raw material collection and pretreatment
Collect cow manure: Collect fresh or dry cow manure from cowsheds or pastures.
Solid liquid separation: If it is wet cow manure, perform solid-liquid separation first to reduce the liquid portion and facilitate subsequent processing.
2. Composting fermentation
Mix cow manure with appropriate amounts of organic materials such as straw, rice straw, sawdust, etc., adjust the carbon to nitrogen ratio (C/N ratio) to a suitable fermentation ratio (approximately 25:1-30:1) to promote microbial activity.
Form a compost pile and use an organic fertilizer turning machine to regularly turn it to ensure air circulation, accelerate fermentation speed, and control internal temperature to achieve the purpose of sterilization and deodorization.
3. Screening and crushing
After fermentation is complete, use a screening machine to remove non decomposable large particles or foreign objects. If necessary, use a grinder to grind the material to a finer state for subsequent granulation.
4. Adding auxiliary materials and mixing
Microbial agents, minerals, trace elements, etc. can be added at this stage to enhance fertilizer effectiveness, and the formula can be adjusted according to the needs of different crops.
5. Granulation
Using an organic fertilizer granulator to press the mixed raw materials into granules, common granulation methods include extrusion granulation, rotary disc granulation, extrusion crushing method, etc.
6. Drying and Cooling
The particles need to undergo a drying process to reduce the moisture content to an appropriate level to prevent decay or bacterial growth; After cooling to room temperature, prepare to proceed to the next step.
7. Packaging and Storage
Finally, weigh, package, and label the cooled organic fertilizer particles, store them in a cool and dry place, and wait for distribution.
Advanced technology application
Modern organic fertilizer production lines may also integrate automatic control systems, such as temperature and humidity monitoring and regulation, as well as clean production technologies, such as exhaust gas purification, wastewater treatment, etc., to ensure that the entire process is both efficient and environmentally friendly.
This entire process aims to maximize the utilization of nutrients in cow manure while eliminating potential pathogens and other harmful substances through scientific methods, ensuring that the produced organic fertilizer is both safe and effective.
