Abstract

The invention discloses a center exhaust device of a stirring shaft of a fermentation tank and relates to the technical field of fermentation equipment. The center exhaust device comprises a fermentation tank and a stirring device, wherein a connector for connecting the stirring device is arranged at the upper end of the fermentation tank; a three-way pipe is arranged in the connector; the three-way pipe is T-shaped and comprises a first interface, a second interface and a third interface which are mutually communicated; the first interface and the second interface are positioned on the same vertical line; the first interface is communicated with the upper end of the connector; the second interface penetrates through the lower end of the connector and is communicated with the inner wall ofthe fermentation tank; the third interface extends from the side wall of the connector to the outside of the connector; the third interface is an exhaust interface; and the stirring shaft of the stirring device penetrates through the first interface and the second interface and extends into the fermentation tank. The exhaust interface which is originally formed in the fermentation tank is transferred to the connector of the fermentation tank and the stirring shaft, thereby effectively reducing the probability of contamination of the fermentation tank.

Description

technical field

[0001] The invention relates to the technical field of fermentation equipment, in particular to a central exhaust device for a stirring shaft of a fermentation tank. Background technique

[0002] At present, in the fermentation industry, the exhaust device of the fermentation tank is set on the side of the head to discharge the fermentation tail gas. Because the shaft seal of the stirring shaft is easy to form a sterilization dead angle, or the shaft seal is broken, resulting in the inhalation of bacteria outside the tank. In the tank, resulting in a certain probability of contamination. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a central exhaust device for the stirring shaft of the fermenter.

[0004] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0005] A central exhaust devic...
