a biological fermentation tank

Abstract

The invention relates to a biological fermentation tank which comprises a motor, a speed reducer, a stirring device, an upper cover, a fermentation bucket and a support. The upper cover is arranged at the upper end of the fermentation bucket and provided with a stirring opening, and the stirring device is arranged in the stirring opening and comprises a stirring shaft and stirring blades arranged on the stirring shaft. The stirring blades comprise the first stirring blade and the second stirring blade, the second stirring blade is arranged at the lower end of the stirring shaft, the first stirring blade is a flood dragon rotary blade, and the second stirring blade is a frame type stirring blade. Coatings are arranged on the outer sides of the stirring blades, the fermentation bucket is provided with an inner barrel body, an outer jacket and a shell in sequence from inside to outside, a heat preservation device is arranged between the outer jacket and the shell, a heating device is arranged between the inner barrel body and the outer jacket, and a sensor is arranged in the heat preservation device. The stirring blades are formed by combining the flood dragon rotary blade and the frame type stirring blade, therefore, reactants can be comprehensively stirred and can be effectively prevented from being pasted to the inner wall of the fermentation bucket, and the reaction rate is increased.

Description

technical field

[0001] The invention relates to the field of reaction vessels, in particular to a biological fermentation tank. Background technique

[0002] The biological fermentation tank is an external environment device for microorganisms to produce, reproduce and form products during the fermentation process. Compared with traditional containers, it can strictly sterilize the production process of the fermentation tank, and timely feed the fermented products. Stirring, during the production process, it is necessary to automatically control the temperature, pressure, and air flow and provide a good fermentation environment. Fermentation tanks are widely used in the fermentation of microbial strains. They have the advantages of fast fermentation, cleanliness, and large-scale production. During the production and processing of fermentation tanks, a certain degree of cleanliness must be ensured to avoid exposure of the inoculation port and sampling port of the fermentation...
