a liquid fermentation tank

Abstract

The invention provides a liquid fermentation tank which comprises a tank body and a stirring device. The stirring device comprises a ring-shaped hollow guide rail which is fixed to the inner wall of the tank body, a second air inlet pipe which hermetically passes through the tank wall and then is communicated with the guide rail, and a support ring which is coaxially arranged in the guide rail; an opening is formed in the inner side of the guide rail, and a sterilizing filter and a first check valve are arranged on the second air inlet pipe one by one in the air inlet direction; the support ring can rotate about the axis of the support ring, and the inner side of the support ring is in contact with the inner wall on the side, provided with the opening , of the guide rail; a plurality of connecting pipes passing through the opening are uniformly arranged on the inner side of the support ring in the circumferential direction, a mixing blade is arranged at the end, located outside the guide rail, of each connecting pipe which is communicated with the guide rail, and an air jet hole is formed in each connecting pipe. The liquid fermentation tank eliminates the need for a motor, a reducer and a mixer shaft which are required for the traditional mechanical stirring, enables the weight of the whole fermentation tank to be lower, and is low in cost.

Description

technical field [0001] The invention relates to a liquid fermentation tank. Background technique [0002] In the process of liquid fermentation, mechanical stirring is required to evenly distribute the bacteria in the fermentation broth. The traditional mechanical stirring method is that the motor and the reducer drive the stirring shaft to stir, which has the problems of heavy weight and high cost. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a liquid fermenter, while providing sterile air in the fermenter, utilize the eruption of sterile air to push the stirring blades to rotate, thereby eliminating the need for traditional mechanical stirring. The motor, reducer and stirring shaft make the entire fermenter lighter in weight and lower in cost. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a liquid fermenter, comprising a tank body and ...
