[0020] By adopting the above scheme, the utility model starts the blower 20 during fermentation to pump air into the air supply pipe 16. The air in the air supply pipe 16 is heated by the heating mechanism and then enters the gas distributor 17. Thereafter, the air is directly discharged into the liquid culture medium by the gas distributor 17 to ensure the oxygen content in the fermentation tank. The heated air can avoid causing a substantial increase or decrease in the temperature of the liquid culture medium, so as to ensure the stability of the fermentation and achieve a good use effect.
[0021] Specific combination Figure 1 In one embodiment of the utility model, the heating mechanism includes a water tank 22, the air supply pipe 16 passes through the water tank 22, the air supply pipe 16 is distributed in a serpentine shape in the water tank 22, and a water inlet pipe 23 and a water outlet pipe 24 are fixedly penetrated on the water tank 22, and the water inlet pipe 23 and the water outlet pipe 24 are both connected to the oil temperature machine. Specifically, the temperature of the air when it is discharged from the air supply pipe 16 is the same as or close to the temperature of the liquid culture medium in the fermentation tank 1, and the temperature difference between the two should not exceed 1°C.
[0022] By passing the air supply pipe 16 through the water tank 22, the heat exchange medium in the water tank 22 can be used to heat the air supply pipe 16, thereby heating the air in the air supply pipe 16. The air supply pipe 16 distributed in a serpentine shape in the water tank 22 can effectively improve the heat exchange efficiency and has a good use effect.
[0023] Specific combination Figure 1 In one embodiment of the utility model, a duct air filter 21 is installed on the air supply pipe 16, and the duct air filter 21 is located between the blower 20 and the heating mechanism. Through the use of the duct air filter 21, the air entering the fermentation tank 1 can be effectively filtered to prevent external bacteria from entering the fermentation tank 1, so as to ensure the quality of the probiotic product.

[0025] By providing a plurality of air outlet holes 19, the introduced air can be distributed more evenly in the liquid culture medium, and the gas distributor 17 composed of two semi-annular tubes 18 is easy to clean the inside after being split.
[0026] Specific combination Figure 1 In one embodiment of the utility model, the stirring mechanism includes a stirring shaft 7 whose top end is fixedly connected to the output shaft of the motor 6, and a plurality of stirring blades 8 are fixedly connected to the bottom end of the outer wall of the stirring shaft 7 in a circular distribution, and a plurality of through holes 9 are penetrated through the outer wall of the stirring blades 8, and a plurality of baffles 10 are fixedly connected to the interior of the fermentation tank 1 in a circular distribution.
