The core logic for improving the fermentation efficiency of windrow composting machines is to ensure the material is "oxygen-permeable and temperature-uniform," while matching the optimal activity conditions for microorganisms. This can be achieved through five key dimensions, which are simple, easy to implement, and yield quick results:
1. Strictly control the initial material ratio: The carbon-nitrogen ratio (C/N) should be controlled between 25:1 and 35:1 (e.g., a reasonable combination of straw and livestock manure), and the moisture content should be maintained at 55%-65% (it should clump together when squeezed but crumble easily when dropped). This avoids excessive dryness leading to oxygen deficiency or excessive moisture leading to anaerobic conditions, reducing fermentation stagnation from the source.
2. Optimize turning parameters: The turning depth should be adjusted according to the material layer thickness (generally 30-60cm) to ensure the material is loose and free of clumps after turning. Turn the compost every 1-2 days in the early fermentation stage (heating period), every 2-3 days in the middle stage (high temperature period), and every 3-5 days in the later stage (cooling and maturation period). This ensures oxygen supply without wasting the energy consumption of fertilizer produciotn machine.
3. Assisted Heating and Insulation: In low-temperature seasons (below 15℃), cover the fermentation pile surface with a thin film or insulating cotton to help quickly raise the temperature to 55-65℃ (peak temperature for microbial activity); in high-temperature seasons, appropriately increase the frequency of turning the pile to prevent localized overheating (above 70℃) from killing beneficial bacteria.
4. Proper Fermentation Site Planning: Control the width of the fermentation pile to 4-6m and the height to 1.2-1.8m, with the length adjusted according to production capacity. Ensure the tracked turner operates without dead angles and that the material is turned evenly. The site must have proper drainage to prevent rainwater accumulation that could lead to anaerobic deterioration of the material.
5. Adding Fermentation Aids: Targeted addition of straw composting agents, compound microbial agents, etc., accelerates the decomposition of cellulose and protein, shortens the fermentation cycle (usually reducing it by 3-7 days), and improves compostability, preventing secondary fermentation.
