In organic fertilizer production, the quality of compost turning during the fermentation process directly determines fertilizer maturity and nutrient retention. The double screws compost turning machine, with its unique structural design, is a key device for addressing uneven compost turning and slow fermentation. Its dual helical operation ensures sufficient oxygen and uniform heat dissipation within the fermentation tank, significantly improving fermentation efficiency.
The core working components of the double screws compost turning machine are two sets of parallel spiral blades. As the device moves along the fermentation tank track, the blades rotate clockwise, tossing the bottom material upward while simultaneously dispersing it to the sides. This turning method creates a “rolling up and down, mixing left and right” motion pattern for the material.
During the fermentation process, turning the compost not only provides sufficient oxygen for microorganisms but also quickly dissipates heat generated by the fermentation process, preventing nutrient loss due to localized high temperatures. For different raw materials such as livestock and poultry manure, straw, etc., the spiral speed and double screws compost turning machine movement speed can be adjusted to control the turning depth (up to 1.5-3m) and frequency, ensuring that the materials are fully composted within 7-15 days. Compared with manual turning, the efficiency is increased by more than 10 times.
