The inlet and outlet port 913 is communicated with the annular nozzle 12.

[0039] By adopting the technical scheme, the gas generated by the fermentation of the material is discharged into the communication device 9 through the annular nozzle 12, and then discharged to the outside through the communication device 9, so as to ensure that the internal pressure of the fermentation tank body 1 is always equal to the outside, thereby achieving the protection effect and effectively avoiding the safety hazard caused by the excessive pressure in the fermentation tank body 1 due to fermentation.

[0040] In the embodiment, the exhaust port 911 and the water inlet 915 are communicated with the inlet and outlet port 913 through the inner connecting port 912, the pressurizing port 914 is communicated with the air pump through the pipeline, the water inlet 915 is communicated with the water pump through the pipeline, the first valve rod 92 is slidingly connected in the valve body 91, the bottom of the first valve rod 92 is located in the pressurizing port 914, the first spring 93 is sleeved outside the first valve rod 92, the bottom of the first spring 93 is in contact with the first valve rod 92, and the top of the first spring 93 is in contact with the inner wall of the valve body 91.

[0041] By adopting the technical scheme, when the material in the fermentation tank body 1 is converted into gamma-aminobutyric acid by lactic acid bacteria, the discharge valve at the bottom of the fermentation tank body 1 is opened, the air pump is in running state, the air in the pressurizing port 914 pushes the first valve rod 92 open, the first spring 93 is contracted under stress, the first valve rod 92 blocks the inner connecting port 912, the pressurizing port 914 is in communication with the inlet and outlet port 913, and the air pump pressurizes the inside of the fermentation tank body 1, so as to accelerate the discharge of the material from the inside of the fermentation tank body 1 under the influence of pressure, shorten the discharge time, and effectively improve the preparation efficiency of gamma-aminobutyric acid.

[0042] In this embodiment, the second valve stem 94 is slidably connected inside the valve body 91, the bottom of the second valve stem 94 is located inside the water inlet 915, the second spring 95 is fitted outside the second valve stem 94, the bottom of the second spring 95 is in contact with the second valve stem 94, and the top of the second spring 95 is in contact with the inner wall of the valve body 91.

[0043] Using the above technical solution, after the material inside the fermentation tank 1 is drained, the air pump stops running. The first valve stem 92 is reset under the influence of the first spring 93, sealing the pressurization port 914. The water pump is running, and the water flow at the inlet 915 pushes open the second valve stem 94. The second spring 95 is compressed under force, and the second valve stem 94 seals the exhaust port 911. The inlet 915 is connected to the inlet and outlet ports 913 through the internal connection port 912. The water pump delivers water to the annular spray pipe 12, and the spray hole 121 sprays water out to wash away the material residue remaining on the inner wall of the fermentation tank 1 and the impeller 7, ensuring the cleanliness of the inside of the fermentation tank 1 and effectively preventing the material residue from deteriorating and affecting the quality of the next batch of γ-aminobutyric acid preparation.

[0044] The working principle of this embodiment is as follows: The materials required for the preparation of γ-aminobutyric acid (GABA) are injected into the fermentation tank 1. Lactic acid bacteria ferment the materials, and the gas produced during fermentation is discharged into the communicating vessel 9 through the annular nozzle 12, and then discharged to the outside through the communicating vessel 9, ensuring that the gas pressure inside the fermentation tank 1 is always equal to that outside. Simultaneously with the fermentation, the motor 3 drives the reciprocating screw 4 to rotate, which in turn drives the small gear 6 to rotate. The small gear 6, due to its meshing with the gear ring 11, drives the planetary carrier 5 to rotate, which in turn drives the impeller 7 to rotate synchronously. The impeller 7 thoroughly stirs the materials, ensuring complete fermentation. The reciprocating screw 4, through the reciprocating slider 8, drives the impeller 7 to move up and down, changing the height of the impeller 7 and effectively improving the stirring efficiency. After the materials inside the fermentation tank 1 are converted into GABA by lactic acid bacteria, the discharge valve at the bottom of the fermentation tank 1 is opened, and the air pump is in operation. Air at the pressurization port 914 pushes open the first valve stem 92, causing the first spring 93 to contract under pressure. The first valve stem 92 then seals the inner connection port 912, connecting the pressurization port 914 with the inlet / outlet port 913. The air pump pressurizes the inside of the fermentation tank 1, causing the material to be discharged from the fermentation tank 1 more quickly due to the pressure. After the material inside the fermentation tank 1 is completely discharged, the air pump stops running, and the first valve stem 92 resets under the thrust of the first spring 93. The pressurization port 914 is blocked, the water pump is running, the water flow at the inlet 915 pushes open the second valve stem 94, the second spring 95 is compressed by force, the second valve stem 94 blocks the exhaust port 911, the inlet 915 is connected to the inlet and outlet ports 913 through the internal connection port 912, the water pump delivers the water flow to the annular spray pipe 12, the spray hole 121 sprays the water flow out, and washes the material residue remaining on the inner wall of the fermentation tank 1 and the impeller 7.
