1. Pile turning: The fermentation compost turning machine is mainly used to turn the organic materials in the composting process, so that the materials are more uniform in the fermentation process of the organic fertilizer production line and improve the quality of the compost.

2. Mixing: Organic fertilizer turning machine can mix different materials to make the proportion of materials more reasonable, which is conducive to the fermentation process.

3. Air permeability: In the stacking process, the organic fertilizer stacking machine can improve the air permeability of compost materials, which is conducive to the respiration and growth of microorganisms, and accelerate the decomposition of organic matter.

4. Drainage: The organic fertilizer turnover machine helps to discharge excess water during the turnover process, preventing the compost material from being too wet and affecting the fermentation effect.

5. Control the temperature: By turning the pile, the organic fertilizer turning machine can adjust the temperature during the composting process to keep it in a suitable range, which is conducive to the growth and fermentation of microorganisms.

6. Promote nutrient release: Organic fertilizer turning machine helps to fully release nutrients in organic materials and improve the fertility of compost.

7. Reduce odor: The organic fertilizer turning machine can reduce odor in the composting process and reduce the impact on the environment by turning the pile.

8. Improve the composting speed: The organic fertilizer turning machine can accelerate the decomposition of organic matter, shorten the composting cycle, and improve the composting yield. 
 In short, the organic fertilizer turnover machine plays a key role in the composting process, helping to improve the quality, speed and fertility of the compost, while reducing environmental pollution.
