[0065] and a power module for driving the plurality of rotating shafts 15 to rotate, wherein the rotating box 11 has a cavity for accommodating the power module;

[0066] The power module comprises:

[0067] The second rotating shaft 19 is rotatably mounted on the rotating box 11, and the two ends of the second rotating shaft 19 are respectively fixedly mounted with a driving pulley 32 and a gear 18;

[0068] An inner gear ring 12 meshing with a gear 18, wherein the inner gear ring 12 is fixedly installed in the fermentation tank 1;

[0071] In this embodiment, in the initial state, the multi-group diverter plate 14 forms a large arc structure. The driving component can make the control block 25 and the rotating box 11 rotate synchronously by driving the rotating tube 10 and the rotating shaft 3 33 to rotate synchronously, so that the diverter plate 14 rotates with the rotating tube 10 as the axis, so that the materials are dispersed to both sides.

When the rotating shaft 15 moves following the moving block 17, the elastic telescopic rod 30 will push the tensioning wheel 31 to further press the transmission belt 28, so that the transmission belt 28 can always achieve power transmission between the driven pulley 29 and the active pulley 32, which is convenient for driving the rotating shaft 15 to rotate.

[0072] In one embodiment of the present invention, see Figure 1-Figure 8 , the auxiliary components include:

[0073] A second stirring plate 21, wherein the second stirring plate 21 is fixedly mounted on a third rotating shaft 33;

[0074] And a scraper rod 13 fixedly installed at the bottom of the rotating shaft 33, the end of the scraper rod 13 is fixedly connected to the rotating box 11, and the scraper rod 13 is an L-shaped structure, and the scraper rod 13 is in sliding contact with the inner wall of the fermentation tank 1.

During the fermentation process, the oxygen content in the fermentation tank 1 can be increased, and the solubility of oxygen can be increased, thereby improving the fermentation effect. At the same time, by increasing the volume, it can also have a certain defoaming effect to prevent excessive foam formed by stirring. During the stirring process, the expansion tank 3 can drive the material to move back and forth by moving up and down, so that the contact state between the material and the mixing mechanism changes, thereby improving the stirring effect, so that the materials and the materials and the oxygen can be fully mixed; the expansion tank 3 can reduce the volume during stirring, and expand the volume according to demand during fermentation, which is more practical.
