[0027] like Figures 1-3 The diagram shows a probiotic liquid fermentation culture tank. During fermentation, when the amount of gas in the probiotic liquid within the tank body 1 is low, the position of the vent hole 502 on the vent piston rod 5 is lower than the position of the vent horizontal hole 122 (e.g., ...). Figure 3When the gas produced in the fermentation in the fermentation tank main body 1 continuously increases, the gas in the fermentation tank main body 1 continuously strengthens, and the gas in the fermentation tank main body 1 flows into the exhaust casing 3 through the exhaust port 201 on the tank cover 2, then flows into the exhaust recess 501 on the exhaust piston rod 5 through the exhaust channel 401, and the gas flow promotes the upward lifting of the exhaust piston rod 5 and the piston 4 through the exhaust recess 501 under the action of the continuously strengthened gas pressure, and the upward movement of the exhaust piston rod 5 will press the second reset spring 11 and drive the end block 6 to move upward and stretch the first reset spring 7; when the exhaust piston rod 5 continuously lifts upward under the continuously strengthened gas pressure, the position of the exhaust hole 502 on the exhaust piston rod 5 will move to the position of the exhaust transverse hole 122, so that the gas in the exhaust casing 3 will be sequentially discharged to the outside through the exhaust channel 401, the exhaust recess 501, the exhaust hole 502 and the exhaust transverse hole 122.
