The organic wastes such as livestock manure and other organic wastes are mixed with fermentation agent and auxiliary materials (the moisture content is 50-60%), and they are sent to the front end of the fermentation tank by forklift truck (1 / 8 of the original empty tank front end or 1 / 8 of the pool front end vacated after pile turning).
The thickness of fermentation materials in the tank is 1.5-1.6 M. the forced ventilation of high-pressure fan and the oxygen provided by the material contacting with the air during pile turning are used for continuous aerobic fermentation The fermentation period is 7-8 days.
Under the action of longitudinal and transverse walking mechanism, the scraper of multi tooth plate structure conveyor with an angle of 45 degrees with the bottom of the tank will continuously and gradually pick up the fermentation materials and transport them to the highest point along the bottom of the tank, and then throw them down to make them pile up again and produce certain displacement.
After turning twice a day, the whole process of continuous aerobic fermentation was completed. The daily fermented materials (1 / 8 of the daily treatment capacity) are transported away from the end of the fermentation tank with a forklift truck.
The space vacated at the front end of the fermentation tank is supplemented with new fermentation materials, thus forming a continuous fermentation process. The materials out of the pool are piled into material piles and stored, and the secondary fermentation (10-15 days) is carried out to further decompose and remove some moisture.
