Chicken manure is a high-quality organic raw material rich in nutrients and comprehensive in fertilizing properties; however, in its fresh state, it contains pathogens and parasite eggs and poses a high risk of "burning" plant roots. Consequently, it requires professional processing to be transformed into safe, compliant commercial organic fertilizer.The production process for chicken manure organic fertilizer is mature and standardized, comprising four key stages—raw material blending, high-temperature fermentation, crushing and granulation, and screening and packaging—thereby achieving the harmless treatment and resource utilization of manure waste.
Raw material blending and pretreatment constitute the initial step. Fresh chicken manure has high moisture content and viscosity, as well as an unbalanced carbon-to-nitrogen (C/N) ratio, making direct fermentation impossible. During production, auxiliary materials such as straw, sawdust, and rice husks are mixed in specific proportions to adjust the moisture content and C/N ratio. Simultaneously, impurities like stones, plastic, and debris are rigorously sorted and removed to ensure material purity and uniformity, which effectively accelerates subsequent fermentation and enhances the quality of the finished fertilizer.
High-temperature aerobic fermentation (composting) is the core stage of organic fertilizer production. The blended chicken manure mixture is transported to fermentation tanks, where specialized decomposing microbial agents are evenly sprayed. A compost turner periodically turns and aerates the material to promote rapid temperature rise and fermentation. Temperatures are maintained between 55°C and 70°C; this sustained high heat thoroughly eliminates parasite eggs, pathogens, and weed seeds, while also removing odors and degrading harmful substances. After approximately 20 days of full decomposition, the chicken manure becomes stable and completely broken down, completing the harmless treatment process.
Following decomposition, the material undergoes crushing and granulation. The fermented manure is loose yet uneven and contains clumps, so it must be finely crushed to meet standard particle size requirements. For granular organic fertilizer, the crushed material is fed into a granulator to form and round the granules, followed by drying and cooling to harden them. This results in granules with moderate hardness and uniform shape, effectively solving issues associated with powdered fertilizers, such as dust generation, nutrient loss, and application inconvenience.
Finally, the product undergoes screening and packaging before being warehoused, completing the entire production process. A drum screener is used to separate granules that meet specifications, while substandard material is recirculated for reprocessing; qualified finished products are then quantitatively sealed and labeled by an automated packaging machine before being sent to storage. Produced through a standardized process, this organic chicken manure fertilizer is eco-friendly and pollution-free; it effectively loosens the soil, enhances soil fertility, and improves crop quality, making it an excellent choice for ecological agriculture.
