With the rapid expansion of large-scale livestock and poultry farming, the accumulation and difficult disposal of chicken manure have become wides pread industry challenges. Simultaneously, the agricultural sector faces issues such as soil compaction, chemical fertilizer residues, and declining soil fertility. The chicken manure organic fertilizer production line seamlessly bridges the gap between livestock waste management and ecological farming. By utilizing specialized equipment to process chicken manure—rendering it harmless and converting it into a valuable resource—this system transforms farming waste into high-quality organic fertilizer and establishes a circular "crop-livestock" industry chain. It serves as a core facility for the industry's transition toward sustainable, green agriculture.
The production line employs an integrated, closed-loop process driven by a suite of specialized, coordinated equipment. It comprises six key stages: pre-treatment, high-temperature fermentation, crushing and screening, mixing and granulation, and drying and packaging, ensuring standardized production and consistent efficiency. Fresh chicken manure typically has high moisture content and contains impurities like feathers; therefore, it first undergoes pre-treatment via a solid-liquid separator to purify the material and adjust moisture levels to meet fermentation standards. Next, a fully automated mixer blends the manure with additives such as straw and sawdust to balance the carbon-to-nitrogen (C/N) ratio and incorporates fermentation microbial agents, preparing the mixture for decomposition.
Fermentation is the critical stage of organic fertilizer production, relying primarily on trough-type compost turners or enclosed fermentation tanks to facilitate aerobic, high-temperature decomposition. Continuous turning and aeration allow the material to decompose thoroughly at temperatures between 55°C and 70°C. This process eliminates residual pathogens, insect eggs, and weed seeds within one to two weeks while simultaneously reducing odor and moisture. Unlike traditional open-air composting, mechanized fermentation is unaffected by weather conditions and ensures more complete decomposition. Furthermore, enclosed equipment effectively treats exhaust gases and prevents odor pollution, significantly enhancing environmental safety.
After decomposition, the material is refined and graded using organic fertilizer crushers and rotary screens to break up clumps, remove impurities, and ensure uniform particle size. Finally, the material is fed into a horizontal ribbon mixer where medium and trace elements are added as needed to optimize the fertilizer's nutrient composition. Qualified materials are processed into uniform granules using a disc granulator or a new type organic fertilizer granulator; the granules are then refined for appearance and hardness via a rotary dryer, cooler, and ball shaping machine; finally, an automatic quantitative packaging machine handles sealing and warehousing, resulting in a finished fertilizer product with stable nutrient content that is convenient to store and transport.
The entire production line features a high degree of automation and fully mechanized, integrated operations, significantly reducing labor requirements and making it suitable for large-scale production at small-to-medium-sized livestock farms and organic fertilizer processing plants. The processed chicken manure organic fertilizer boasts high organic matter content and strong microbial activity; long-term application improves soil structure and enhances soil fertility, thereby boosting crop quality and yields.
Amidst strict environmental regulations and the widespread adoption of green farming practices, this chicken manure organic fertilizer production line transforms waste into a valuable resource. It delivers environmental, economic, and ecological benefits, fosters the green and sustainable development of the crop and livestock industries, and holds promising market prospects.
