Fermentation Cycle and Capacity Improvement Techniques for Trench Fertilizer Turners

As a core piece of equipment for standardized organic fertilizer fermentation, the fermentation efficiency of trough fertilizer turners directly determines the overall production line capacity. Properly utilizing the turning rhythm and controlling temperature and humidity changes can effectively shorten the fermentation cycle and improve the yield and quality of the finished product. When using trough fertilizer turners for aerobic fermentation, the turning interval needs to be adjusted according to the material type: livestock and poultry manure can be turned once a day during the heating stage; the interval should be lengthened during the high-temperature constant-temperature stage; and the turning frequency should be reduced during the cooling and composting stage. This ensures sufficient oxygen while minimizing heat loss.

The material pile height in the fermentation trough should be controlled between 1.0 and 1.5 meters. Too high a height can lead to internal anaerobic conditions, while too low a height can cause heat loss. The trough fertilizer turner's built-in frequency conversion speed control function adjusts the walking and turning speed according to the material's dryness, wetness, and viscosity, avoiding problems such as incomplete turning and material clumping. Simultaneously, the equipment's automated control system enables timed and temperature-controlled automatic turning, eliminating the need for manual intervention and precisely controlling temperature changes in the three stages of fermentation. With proper and standardized operation, trough-type fertilizer turners can shorten the conventional 15-day fermentation cycle to about 10 days, resulting in more thorough material decomposition, a higher rate of pathogen and insect egg elimination, and stable organic matter content in the finished organic fertilizer. Scientific management of the turning process and material stacking standards can both increase daily processing capacity and reduce labor and time costs, making it a key method for large-scale organic fertilizer plants to improve quality and efficiency.
