In the fermentation process of organic fertilizer, the compost turning machine should be used to turn and toss regularly to supply enough air to ensure oxygen consumption fermentation. https://www.thefertilizermachine.com/fermentation-compost-turning-series/chain-compost-turning-machine.html
The height of trough compost is high, and it is difficult for oxygen to enter. Therefore, external force is required to force aeration into the pile body. Use organic fertilizer turning equipment to process materials, with high ventilation rate and full automatic control. The fermented materials are then processed into organic compound fertilizer using a fertilizer granulator (https://www.thefertilizermachine.com/fertilizer-granulator-machine-series/new-type-organic-fertilizer-granulator.html) or other granulation equipment.
