The process of producing organic fertilizer from chicken manure involves a series of delicate and systematic technological steps, from the initial collection of chicken manure to the packaging and delivery of the final organic fertilizer product, the entire process is called the organic fertilizer production line. The following are the main steps in producing organic fertilizer from chicken manure:
Chicken manure collection and initial treatment:
Collection: Collect fresh or dry chicken manure from the farm in a timely manner to avoid long-term accumulation that can cause odor and bacterial growth.
Preliminary screening: Remove non organic impurities such as plastics, stones, or other foreign objects from chicken manure to protect subsequent processing equipment from damage.
Solid liquid separation (suitable for chicken manure with high water content):
Using equipment such as spiral extruders or centrifugal dehydrators, the liquid and solid in chicken manure are separated to obtain dry chicken manure cake as raw material for subsequent processing.
Chicken manure crushing:
After drying, chicken manure is crushed by equipment such as chain crushers, hammer crushers, or cage crushers to turn it into small particles or powders for further fermentation and mixing.
Fermentation:
Mix the crushed chicken manure with other auxiliary materials (such as rice husk, straw powder, etc.) in proportion, add microbial fermentation agents, conduct high-temperature composting fermentation, decompose harmful substances, kill pathogens and parasite eggs, and generate beneficial microbial communities to improve fertilizer quality.
Flipping:
During the fermentation process, equipment such as trough type flippers or track type flippers are used to regularly flip materials to ensure oxygen supply, maintain appropriate temperature and humidity, promote microbial activity, and accelerate the fermentation process.
Screening:
After fermentation is completed, use vibrating screens and other equipment to screen the materials, remove large particles or incompletely decomposed residues, and ensure the uniformity and quality of the finished fertilizer.
Secondary crushing and mixing:
Grind the screened fertilizer again to achieve finer particle size; Then mix it thoroughly with appropriate additives (such as trace elements, humic acid, etc.) to adjust the proportion of nutrients and meet the specific needs of crops.
Granulation:
Use equipment such as drum granulators and extrusion granulators to make the mixed fertilizer powder into spherical or cylindrical particles, improving the convenience and aesthetics of fertilization.
Drying and cooling:
Freshly produced fertilizer granules are dried to remove excess moisture, and then cooled down using a cooling machine to prevent mold and spoilage during storage.
Grading and packaging:
Classify according to particle size, and return non-conforming products to the previous stage for reprocessing; Qualified products will be automatically measured, bagged, sealed and packaged for sale.
Quality inspection and storage:
The finished organic fertilizer needs to undergo strict quality inspection to ensure compliance with national standards; By implementing reasonable warehouse management, we can prevent secondary pollution and ensure the freshness and activity of our products.
Through this rigorous and orderly production process, chicken manure can be transformed into high-quality organic fertilizer, which not only realizes waste resource utilization, but also provides a green and healthy source of fertilizer for agricultural production, promoting the development of ecological agriculture.
