Improved oxygen supply device for fermentation tank

Abstract

The invention relates to an improved oxygen supply device for a fermentation tank. The device comprising an oxygen supplement mixing tank body, a gas mixing tube, a pyramidal separator plate, an air pressure gauge, a compressed air inlet tube, a pure oxygen inlet tube, a supplied oxygen outlet tube, a gas flow regulating type flow meter and a condensate water outlet, the oxygen supplement mixing tank body has a closed hollow shape, the air pressure gauge and the supplied oxygen outlet tube are arranged at the top of the oxygen supplement mixing tank body at intervals, and the gas mixing tube is arranged in the hollow part of the oxygen supplement mixing tank body below the supplied oxygen outlet tube. The device adopts closed oxygen supplement mixing tank body oxygenation in order to increase the oxygen dissolution rate, so the device achieves efficient oxygenation and a high oxygenation efficiency, meets use demands, and brings convenience for use; and the arrangement of the gas flowregulating type flow meter makes a user perform real-time adjustment according to the oxygen concentration size required during strain fermentation, meets the oxygen demand of strain fermentation propagation period culture and high-density fermentation, and enlarges the application range of the device.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, in particular to an improved oxygen supplement device for a fermentation tank. Background technique [0002] At present, microbial fermentation is mostly carried out in fermenters. Microorganisms have certain requirements for oxygen concentration when fermenting in fermenters. Only when the concentration of oxygen and other gases meets the requirements can the quality of microbial fermentation be guaranteed. However, when the current fermenter is in use, the dissolution rate of oxygen inside it is relatively low, which sometimes cannot meet the fermentation requirements of microorganisms, affects the fermentation quality of microorganisms, and brings inconvenience to use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an improved oxygen supplement device for fermentation tanks. The device has a ...
