[0028] Fermenter 1 is installed with a total pipe one 7 and a total pipe two 10, the total pipe one 7 is fixedly installed with at least three branch pipes one 8 communicated, each branch pipe one 8 is installed with electromagnetic valve one 9, and the inner end of the branch pipe one 8 away from the total pipe one 7 is fixedly installed on the fermenter 1 and communicated with the inside of the fermenter 1, and the total pipe two 10 is fixedly installed with at least three branch pipes two 11 communicated, each branch pipe two 11 is installed with electromagnetic valve two 12, and the inner end of the branch pipe two 11 away from the total pipe two 10 is fixedly installed on the fermenter 1 and communicated with the inside of the fermenter 1;

[0029] Fermenter 1 is installed with a diaphragm pump 13, and the pipe orifice of the total pipe one 7 and the total pipe two 10 is fixed with the inlet and outlet of the diaphragm pump 13 respectively, three branch pipes one 8 are arranged at the middle, bottom and top positions of the fermenter 1 respectively, and the height of each branch pipe two 11 is at least fifteen centimeters lower than that of each corresponding branch pipe one 8, for example, the height of the branch pipe one 8 at the middle position from the tank bottom is 1m, and the height of the corresponding branch pipe two 11 at the middle from the tank bottom is 85cm.

[0030] When using, culture solution and fermentation bacteria are input into the fermenter 1 through the feed pipe 21, and then fermentation is started with the passage of time, when stirring is needed during fermentation, electromagnetic valve one 9 on any one of the three branch pipes one 8 can be opened, electromagnetic valve two 12 on any one of the three branch pipes two 11 is also opened, and then the diaphragm pump 13 is started, the diaphragm pump 13 works to suck the fermentation liquid in the fermenter 1 through the total pipe one 7 and the opened branch pipe one 8, and then re-inputs the fermentation liquid into the fermenter 1 through the total pipe two 10 and the branch pipe two 11, the fermentation liquid is taken out and returned in the fermenter, the taken-out and returned fermentation liquid is firstly flowed, secondly, when taken out, the fermentation liquid above the branch pipe one 8 converges to the branch pipe one 8, and when returned, the fermentation liquid enters the fermenter 1 from the position of the branch pipe two 11, the taken-out and returned fermentation liquid further drives the surrounding fermentation liquid to move, thereby stirring the fermentation liquid in the fermenter, especially mixing the fermentation liquid between different regions and layers, thereby realizing the stirring effect;

The diaphragm pump 13 and the pipeline will not shear and damage the microorganisms during fermentation. Compared with the existing mechanical stirring, the height position of the stirring blade is fixed, and only the inclination can be used to stir a larger range of fermentation liquid.

[0035] ‌The optimal temperature for GABA fermentation is mainly 33℃, so heating is required. When heating, the electric heating coil 15 is powered through the conductive slip ring 17 to generate heat, and the heat is transferred to the fermentation liquid through the heat conduction cover 16. At the same time of heating, the stirring is started, and the real-time temperature is monitored from the temperature indicator 24 position, so that effective and reliable temperature control can be realized.

[0036] In some embodiments, a heat preservation shell 18 is fixedly installed on the outer side of the fermentation tank 1 to cover the fermentation tank 1, a heat dissipation door 19 is hingedly installed on the heat preservation shell 18 at a position different from the main pipe 7 and the main pipe 10, and an extension rod 20 is hingedly installed between the heat dissipation door 19 and the tank cover 2.
