[0034] Example 1:

[0035] The main structure of this embodiment is as follows: Figures 1-3 As shown, it includes:

[0036] A frame 1 is provided, on which a fermentation tank 2 is provided, and the fermentation tank 2 is provided with a storage cavity with an arc-shaped bottom;

[0037] The main shaft 6 is rotatably mounted inside the fermentation tank 2. The main shaft 6 is coaxial with the arc-shaped section of the storage cavity. Two first spiral plates 7 are arranged on opposite sides of the main shaft 6, and a turntable 8 is coaxially mounted at each end of the main shaft 6 and rotatably connected to the inner wall of the storage cavity. A scraper 13 is provided on the turntable 8 and slides in contact with the arc surface of the storage cavity.

[0038] A hollow shaft 9 is located between and rotatably connected to two turntables 8 on both sides, and two second spiral plates 10 are symmetrically arranged on the hollow shaft 9.

[0039] Drive assembly 15, which is mounted on frame 1 and drives spindle 6 and turntable 8 to rotate;

[0040] A transmission assembly is provided, which drives the main shaft 6 and the hollow shaft 9. When the main shaft 6 is rotating, the first spiral plate 7 and the second spiral plate 10 rotate in opposite directions.

[0041] A discharge mechanism is provided at the bottom of the fermentation tank 2;

[0042] The first air guide pipe 18 has its two ends connected to the fermentation tank 2 and the exhaust end of the hollow shaft 9, respectively.

[0043] The unit also includes a temperature control component, which is mounted on the frame 1. The input end of the temperature control component is connected to the interior of the fermenter 2, and the output end of the temperature control component is connected to the air inlet of the hollow shaft 9.

[0044] The specific operation process is as follows: Raw materials are added into fermentation tank 2, then the second motor is started. The first motor drives the first pulley to rotate, which in turn drives the main shaft 6 to rotate through the transmission of the toothed belt and the second pulley. The rotation of the main shaft 6 pushes the raw materials from both sides towards the center through the first spiral plates 7 on both sides. The rotation of the main shaft 6 also drives the turntable 8 to rotate, which causes the hollow shaft 9 to both rotate on its own axis and revolve around the main shaft 6 under the transmission of the first gear 11 and the second gear 12. This causes the second spiral plates 10 on both sides to disperse the raw materials in the middle to both sides while rotating, thereby achieving rapid mixing of the raw materials. The temperature inside fermentation tank 2 is adjusted by a temperature control component.

[0045] The scraper 13 consists of multiple scrapers arranged in a circular array around the axis of the main shaft 6, with several sets of stirring paddles 14 positioned between the scrapers 13. The stirring paddles 14 stir the raw materials while rotating with the scrapers 13, further improving the mixing efficiency of the raw materials.

The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0050] Example 4:

[0051] This embodiment further defines the structure of the temperature control component based on the above embodiments, such as... Figure 5As shown, the temperature control assembly includes a fan 19, a temperature control box 21, a thermoelectric cooler 24, and a controller.

During the fermentation process, it is necessary to ensure that the temperature inside the fermenter is suitable for bacterial growth. If the temperature inside the fermenter is too high, the semiconductor cooler 24 is activated to cool the fermenter, the temperature of the heat-conducting plate 23 decreases, and the fan 19 is activated. The fan 19 draws air from above the raw materials in the fermenter 2, and the air enters the temperature control box 21 along the air guide pipe B25. The flowing air exchanges heat with the low-temperature heat-conducting plate 23 and cools down. Then, the low-temperature air is sent into the hollow shaft 9 by the fan 19. The low-temperature air exchanges heat with the hollow shaft 9, and the temperature of the hollow shaft 9 decreases. The hollow shaft 9 then exchanges heat with the high-temperature raw materials, cooling the raw materials. Subsequently, the air in the hollow shaft 9 flows back into the fermenter 2 through the air guide pipe A18 and re-enters the temperature control box 21.
