The optimization of the double screws compost turning machine process focuses on four core areas: fermentation efficiency, turning uniformity, equipment stability, energy consumption, and environmental protection, while also considering the actual production needs of organic fertilizer fermentation produciton lines.
Regarding the turning structure, the spiral blade angle, pitch, and rotation direction have been optimized. An opposed double-helix structure is adopted to prevent material imbalance and missed turning, improving the exchange efficiency between upper and lower layers and resulting in more uniform fermentation temperature and humidity. Crushing teeth and anti-winding structures are added to reduce the entanglement and jamming of straw and long-fiber materials, making it suitable for high-moisture and high-viscosity organic materials.
In terms of power and transmission, variable frequency speed regulation and soft-start control are adopted. The spiral speed and travel speed are automatically adjusted according to the material moisture content and fermentation temperature, reducing impact load and wear on bearings, gears, and other vulnerable parts. The transmission sealing structure has been optimized to prevent dust and material infiltration, extending equipment life and reducing the failure rate.
In terms of co-optimization of the fermentation process, it is linked with the temperature and humidity monitoring of the fermentation tank to automatically set the turning frequency and depth, ensuring that the fermentation temperature remains stable at 55-70℃, accelerating aerobic fermentation, and shortening the composting cycle. By rationally controlling the depth and width of turning, oxygen transfer efficiency is improved, odor generation is reduced, and the maturity and quality of organic fertilizer are enhanced.
Simultaneously, environmental protection and operation and maintenance optimization are strengthened. The blades are made of wear-resistant alloy material to improve durability; and simple dust removal and deodorization interfaces are provided for easy connection to environmental protection systems. Through coordinated improvements in structure, control, and process, more uniform turning, more efficient fermentation, lower energy consumption, and more stable operation are achieved, meeting the continuous and stable production needs of large-scale organic fertilizer production lines.
