[0021] From the above description, it can be seen that the utility model has the following beneficial effects: by setting the mixing paddle 17 and the spiral stirring paddle 18, during the operation of the device, the mixing paddle 17 rotates under the drive of the rotating shaft 15, thereby stirring the fermented material inside the device to mix it, and at the same time the spiral stirring paddle 18 can drive the fermented material below to surge upward, and then be stirred and mixed by the mixing paddle 17, so that the mixing can be made more uniform, so that the fermentation degree of the fermented material in various places inside the device can be more uniform.

[0022] For further information, see Figure 4 A coil 23 is wound around the outside of the tank body 1, and the outside of the coil 23 is covered with a protective shell 9, a drain pipe 10 is plugged into the outer wall of one side of the protective shell 9, and a water inlet pipe 11 is plugged into the outer wall of the other side of the protective shell 9, and the drain pipe 10 and the water inlet pipe 11 are respectively connected to the two ends of the coil 23. A temperature and humidity sensor 5, an air pressure valve 6 and a control valve 7 are threadedly connected on the top outer wall of the tank body 1. The temperature and humidity sensor 5 is used to monitor the temperature and humidity inside the tank body 1, and the air pressure valve 6 is used to connect an external pipeline to balance the air pressure inside the tank body 1, and a sampling tube 8 is threadedly connected to one end of the control valve 7, and the sampling tube 8 is convenient for the operator to take samples.

[0023] Example 2: Please refer to Figures 1 to 4As shown, on the basis of the first embodiment, the utility model provides a technical solution: a mounting frame 20 is fixedly installed on the bottom inner wall of the tank body 1 by bolts, and a planetary gear transmission 21 is fixedly installed on the top outer wall of the mounting frame 20 by bolts, which is used to adjust the rotation speed of the impeller 22 so that its rotation speed is higher than the rotation speed of the rotating shaft 15, the bottom end of the rotating shaft 15 is keyed to the inside of the input end of the planetary gear transmission 21, and the output end of the planetary gear transmission 21 is keyed to the impeller 22, and an air intake pipe 19 is inserted on the outer wall of one side of the tank body 1, and one end of the air intake pipe 19 passes through the bottom of the impeller 22.

[0024] By adopting the above technical solution, an air intake pipe 19 and an impeller 22 are set. When the device is running, the rotating shaft 15 can drive the impeller 22 to rotate through the planetary gear transmission 21. At the same time, the air intake pipe 19 sends external air into the interior of the device. Since one end of the air intake pipe 19 is located below the impeller 22, the exhausted air can be broken up by the fast-moving impeller 22 to form smaller bubbles, so as to increase the contact area between the bubbles and the fermentation material and improve the utilization rate of oxygen in the air.

[0025] For further information, see Figure 1 The outer wall of the side of the tank body 1 is welded with support frames 13 distributed at equal distances, and the inside of the support frames 13 is welded with lifting ears 14 to facilitate the lifting of the tank body 1.

[0026] The working principle and use process of the utility model are as follows: during installation, the operator lifts the device through the lifting lug 14, and then fixes the device in a suitable position through the support frame 13, and then connects the external water pipe to the drain pipe 10 and the water inlet pipe 11 respectively, and then connects the air pressure valve 6 to the external balanced air pressure air pipe, and finally connects the external air pipe to the air inlet pipe 19; during use, the operator first puts the material to be fermented into the tank body 1 through the feed port 4, and then the operator starts the device, and the motor 3 drives the rotating shaft 15 through the reducer 2 The rotating shaft 15 drives the mixing paddle 17 and the spiral stirring paddle 18 to rotate, thereby stirring the fermentation material inside the device and mixing it. At the same time, the external air is sent into the interior of the tank body 1 through the air inlet pipe 19, and the sent gas is dispersed in the fermentation material by the impeller 22 to provide oxygen for aerobic bacteria. When the temperature inside the tank body is too high, cooling water can be sent into the interior of the coil 23 through the water inlet pipe 11 to cool the tank body 1. After the fermentation is completed, the operator closes the device and then discharges the fermentation material through the discharge pipe 12.
