At this time, the first cutting knife 11 performs the first crushing of the material through the shearing effect with the fixed cutting knife 10, and the crushed material enters the upper inner tank body 2. At this time, the adjusting stirring knife 9 stirs the material after the first crushing during the rotation process, and sends the screened material into the upper inner tank body 2. At this stage, according to the requirements of composting fermentation, straw, wheat bran and other carbon source-rich auxiliary materials are added to the material in proportion to adjust the humidity of the material to the ideal range of 60%-70%, and optimize the C / N ratio to meet the needs of microorganisms for efficient decomposition of organic matter.

The lower inner tank body 3 is also equipped with a heat exchange system to export the heat generated by the fermentation to provide a heat source for the combustion equipment.

[0077] S10, drying and dehydration; after the secondary fermentation is completed, the fermentation product is finely crushed by a cutting system composed of a fixed cutter 10, a first cutter 11, a second cutter 12 and a third cutter 13, so that the subsequent drying step can more effectively remove excess water.

[0082] The adjusting dial 7 located inside the fixed plate 17 passes through one end of the stirring shaft 4 and is fixedly connected to a switch lever 22 . The surface of the switch lever 22 perpendicular to the axis of the stirring shaft 4 is close to one end of the movable plate 18 and abuts against the movable plate 18 .

[0083] The outer ends of the upper inner tank body 2 and the lower inner tank body 3 are fixedly connected to the upper outer tank body 23 and the lower outer tank body 24 respectively, and an upper heat exchange chamber 25 and a lower heat exchange chamber 26 are respectively opened between the upper inner tank body 2 and the upper outer tank body 23 and between the lower inner tank body 3 and the lower outer tank body 24, and a feed hopper 27 is fixedly connected to the top of the upper inner tank body 2.

[0084] A plurality of external pipes 28 are fixedly connected to the outer ends of the upper inner tank body 2 and the lower inner tank body 3. The ends of the plurality of external pipes 28 at the outer end of the upper inner tank body 2 that are away from each other all penetrate the upper outer tank body 23 and extend to the outside of the upper outer tank body 23. The ends of the plurality of external pipes 28 at the outer end of the lower inner tank body 3 that are away from each other all penetrate the lower outer tank body 24 and extend to the outside of the lower outer tank body 24. The plurality of external pipes 28 can be selectively connected to external equipment according to the configuration. Each of the upper inner tank body 2 and the lower inner tank body 3 has an external pipe 28 connected to external high-pressure oxygen equipment.
