[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0033] Please refer to Figures 1-5, a constant-temperature fermentation tank, comprising a base 1. Inside the base 1 is a fermentation tank body 101. At the upper and lower ends of the fermentation tank body 101 are respectively a feed pipe 102 and a discharge pipe 103, which facilitate feeding and discharging. Inside both the feed pipe 102 and the discharge pipe 103 are valves 104. On the inner wall of the fermentation tank body 101 is a heating plate 105, which can heat the raw materials to maintain the temperature inside the fermentation tank body 101. At the upper end of the base 1 is a support plate 106. At the upper end of the fermentation tank body 101 is a pressure relief cylinder 2, which is used for pressure relief. On both the left and right sides inside the fermentation tank body 101 are rotatably connected to a rotating shaft 3. There are two rotating shafts 3. At the upper end of the rotating shaft 3 is a transmission disc 301. A belt 302 is sleeved between the two transmission discs 301. The belt 302 can drive the two rotating shafts 3 to rotate simultaneously. On the surface of the rotating shaft 3 are a number of stirring blades 303 distributed at equal intervals. At the upper end of the fermentation tank body 101 is a first motor 304. The bottom end of the first motor 304 is fixedly connected to the rotating shaft 3. The first motor 304 can drive the two rotating shafts 3 to rotate simultaneously through the belt 302, thereby causing the stirring blades 303 to stir the raw materials. At the upper end of the base 1 is a stirring assembly 4, which can stir the raw materials vertically.

[0034] Specifically, the stirring assembly 4 includes a second motor 407. The second motor 407 is fixedly connected to the base 1. The rear end of the second motor 407 is connected to a vertical plate 408. At the rear end of the vertical plate 408 is a sliding column 409. The second motor 407 can drive the sliding column 409 to perform a circular motion through the vertical plate 408. On the surface of the sliding column 409 is an elliptical ring 406. The sliding column 409 is slidably connected to the elliptical ring 406. When the sliding column 409 moves, it can squeeze the elliptical ring 406 to move reciprocally in the horizontal direction. At the left end of the elliptical ring 406 is a transmission plate 404. At the upper end of the transmission plate 404 is a rack 405. The rack 405 meshes with a gear 403. When the rack 405 moves, it can drive the gear 403 to rotate, thereby causing the roller shaft 401 to rotate. At the upper end of the base 1 is a support plate 106. The transmission plate 404 is slidably connected to the support plate 106. The support plate 106 can keep the transmission plate 404 stable.

[0035] Through the above technical solution, the second motor 407 can drive the sliding column 409 to perform a circular motion through the vertical plate 408, thereby squeezing the elliptical ring 406 to move in the horizontal direction. The elliptical ring 406 pushes the transmission plate 404 to move left and right, thereby causing the gear 403 to rotate reciprocally, driving the stirring plate 402 to stir the raw materials.

[0036] Specifically, there are several evenly distributed exhaust holes 201 on the surface of the air release cylinder 2. Inside the air release cylinder 2, there is a sliding shaft 202. The upper end of the sliding shaft 202 is fixedly connected to the air release cylinder 2. A retaining disk 203 is sleeved on the surface of the sliding shaft 202. The retaining disk 203 is in contact with the inner wall of the air release cylinder 2. There is a limit ring 204 at the bottom end of the sliding shaft 202, which can prevent the retaining disk 203 from detaching from the sliding shaft 202. A spring 205 is sleeved on the surface of the sliding shaft 202. The spring 205 is located above the retaining disk 203, and the spring 205 can push the retaining disk 203 downward by its elastic force.

[0037] Through the above technical solution, when the air pressure inside the fermentation tank is too high, the air pressure will lift the retaining disk 203 and make it slide upward. At this time, the gas will be discharged from the exhaust holes 201, realizing automatic pressure relief.

[0038] During use, the raw materials are added into the fermentation tank through the feed pipe 102. Subsequently, the electric hot plate is started to heat the inside of the fermentation tank. Then, the first motor 304 drives the two rotating shafts 3 to rotate simultaneously through the belt 302, so as to stir the raw materials by the stirring blades 303. At the same time, the second motor 407 can drive the sliding column 409 to do circular motion through the vertical plate 408, thereby squeezing the oval ring 406 to move horizontally. The oval ring 406 pushes the transmission plate 404 to move left and right, thereby making the gear 403 rotate reciprocally and driving the stirring plate 402 to stir the raw materials, greatly improving the mixing rate of the raw materials. When the air pressure inside the fermentation tank is too high, the air pressure will lift the retaining disk 203 and make it slide upward. At this time, the gas will be discharged from the exhaust holes 201, realizing automatic pressure relief.
