Microbial fermentation tank for production

Abstract

The invention provides a microbial fermentation tank for production. The microbial fermentation tank for production comprises a tank body, a sealed tank cover, support legs and a controller, a stirring motor is arranged at the middle position of the sealed tank cover, the output shaft of the stirring motor is fixedly connected with a stirring shaft through a shaft coupling, one side of the stirring shaft extends into the tank body, the stirring shaft is fixedly provided with stirring paddles, a water bath constant-temperature room is arranged outside the tank body, one side of the upper end ofthe water bath constant-temperature room is connected with a water conveying tube, is sequentially connected with a water pump, a heater, a circulating water tank and a refrigerator through the waterconveying tube, and is connected to the other side of the upper end of the water bath constant-temperature room through the water conveying tube, one side of the lower end of the tank body is connected with an oxygen generator through a gas conveying tube, and a temperature sensor, a pressure sensor, a dissolved oxygen electrode and a pH electrode are arranged in the tank body. The microbial fermentation tank can effectively control the temperature, the pressure, the pH value and the dissolved oxygen content in the fermentation tank while stirring uniformly, and has a high practicability.

Description

technical field [0001] The invention relates to the field of equipment manufacturing, in particular to a microbial fermenter for production. Background technique [0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation not only depends on the genetic characteristics of the strain itself, but also has a lot to do with the culture conditions. During the fermentation process, temperature, pressure, pH, dissolved oxygen and stirring state need to be controlled. Fermentation tanks are mainly used for cultivation in China, but the volume of the fermentation tanks is large, and there are many materials during mass production, so it is difficult to control the cultivation conditions. [0003] The Chinese invention "A Microbial Fermentation Tank" (authorized publication number CN107177481A) provides...

Problems solved by technology

Although the microbial fermenter provided by this invention can stir evenly, it does not effectively control the temperature, pressure, pH, and itching content required for microbial fermentation, and cannot reach the optimal culture conditions for microbial fermentation.
