Background technique

The fermentation tank is an external environment device for microorganisms to grow, reproduce and form products during the fermentation process. The growth of microorganisms requires a large amount of heat. The optimal growth temperature for microorganisms is generally around 20-30 degrees Celsius. Exceeding the temperature will easily cause bacterial growth. death, so during the work process, the temperature needs to be artificially controlled within the permitted range. Therefore, a cooler is often installed in the fermentation tank. At the same time, a stirring shaft needs to be installed in the fermentation tank to improve the cooling effect. Since some fermentation tanks are To meet production needs, the tank body is taller, and the longer mixing shaft has the problem of insufficient support strength. It is easy to be damaged after long-term use. A common solution on the market is to place a gap between the end of the mixing shaft away from the driving mechanism and the inner wall of the tank. A set of supports is provided to support the lower end of the mixing shaft. Compared with the previous form of fixing only one end of the mixing shaft, the service life is indeed improved to a certain extent. However, there are generally stirring blades on the long shaft, and the stirring blades are under stress during the mixing process. state and sometimes the magnitude of the force is different, and the improved structure is fixed at the upper and lower ends and is not fixed in the middle, it is still easy for the suspended part of the mixing shaft between the two fixed ends to bend, eventually leading to damage;

To sum up, it is necessary to improve the internal support structure of the biofermenter to improve its stability.
