In the production of chicken manure organic fertilizer, the fermentation process is the core of achieving harmlessness and resource utilization, and the compost turning machine is the "key equipment" in this process. It ensures aerobic fermentation by turning the material, controlling the pile temperature, and directly affecting fermentation efficiency, product quality, and environmental protection. Choosing the right turning machine requires considering production scale, site conditions, and environmental requirements. Currently, mainstream models each have their suitable scenarios, and precise selection can maximize benefits.
For small-scale production scenarios such as family farms or small-scale breeding farms, windrow compost turning machines are the preferred choice. Their biggest advantage is their flexible mobility, eliminating the need for fixed fermentation tanks and allowing for easy adjustment of the work area, saving significant construction costs. This model is suitable for processing 1-5 tons of chicken manure per day, with a turning width of 3-5 meters. Turning the pile once a day is sufficient to ensure adequate oxygen content, with a fermentation cycle of 15-20 days. It is easy to operate and has low maintenance costs, easily meeting the harmlessness requirements of small-scale production.
For medium-sized production enterprises (processing 5-20 tons per day), trough-type compost turning machines are a cost-effective option. They operate along fixed tracks, ensuring stable operation and uniform turning, effectively avoiding fermentation dead zones and guaranteeing consistent product quality. A configuration with a fermentation tank width of 3-5 meters and a depth of 1.5-2 meters can meet medium-capacity needs, and the equipment cost and energy consumption are relatively controllable. Coupled with simple deodorization equipment, it can meet environmental requirements and is a mainstream choice for small and medium-sized organic fertilizer plants.
For large-scale production (processing more than 20 tons per day), large- wheel compost turning machines are more suitable. Thanks to their extra-large diameter wheel design, the turning width can reach 6-8 meters and the depth 2-3 meters, with a single turning capacity far exceeding that of ordinary models, efficiently handling large-scale pile fermentation needs. It uses a powerful stirring and turning structure, allowing for more uniform mixing of chicken manure and auxiliary materials, ensuring consistent overall fermentation results and effectively shortening the fermentation cycle to 8-12 days. At the same time, the large wheel compost turning machine supports continuous operation, with a maximum hourly output of up to 60 tons, and can be combined with multiple sets of wheels for collaborative work, adapting to the assembly line operation mode of large-scale organic fertilizer production bases. Although the initial equipment investment is high, it can significantly improve the efficiency of large-scale production, reduce labor costs per unit of output, and, when combined with enclosed operating hoods and exhaust gas treatment systems, can meet strict environmental emission requirements and comply with industrial-scale production standards.
In summary, the key to selecting a compost turning machine for chicken manure organic fertilizer production is "matching the scale and adapting to local conditions." Small-scale operations should choose flexible crawler-type machines, medium-sized operations should choose stable trough-type machines, and large-scale operations should choose high-efficiency, high-output large-wheel composting machines. Only then can the process of transforming chicken manure into valuable resources be efficient and compliant, truly achieving a win-win situation for both environmental protection and profitability.
