Do you know about microbial fermentation tanks?
Microbial fermentation tanks are suitable for microbial culture tanks. Dissolved oxygen value is a key parameter in microbial culture. The dissolved oxygen level will affect the growth of microorganisms, the rate of intracellular chemical reactions, and the synthesis of intracellular compounds.

Too low dissolved oxygen level will lead to the accumulation of a large number of by-products and affect normal fermentation. Too high dissolved oxygen level will generate active oxygen, which will cause irreversible damage to the growth of microorganisms and the synthesis of intracellular compounds.

Different microorganisms have different requirements for dissolved oxygen. According to the oxygen requirements of microorganisms, the appropriate level of dissolved oxygen can be controlled to achieve high-density fermentation of microorganisms. Therefore, it is urgent to design a system that can meet the oxygen requirements of different microorganisms and the dissolved oxygen value can be Adjusted fermentation tank device.

Microbial fermentation tanks are indispensable in the industrial application of modern society. Fermentation tanks have replaced traditional fermentation vessels; culture bottles, sauce tanks and wine cellars, and fermentation tanks can be produced on a large scale, using raw materials to a large extent and increasing the rate. And yield.

As a kind of microbial culture reactor, the fermentor can mix the materials uniformly, make the gas well dispersed in the liquid phase, make the solid particles uniformly suspend in the liquid, and make the other non-uniform liquid phase uniformly suspended or fully emulsified. Strengthen the mass and heat transfer between materials.

The fermentation tank is mainly composed of a tank body, a stirring device, a heat transfer device, and a shaft sealing device. Other accessories can be added according to the needs of production. 

If you need to repair the internal parts, feed and discharge, various pipes will be installed, and you need to control and watch the temperature and pressure of the material. You can install thermometers, pressure gauges, sight glasses and other devices.

The body of the fermenter is composed of a cylinder and a head, which provides a certain space for the reaction of materials. The stirring device is composed of a transmission device, a stirring shaft and a stirrer. It is used to uniformly mix various materials participating in the reaction, which can speed up the reaction of the materials and make the reaction more fully.

The heat transfer device is to set a serpentine tube inside the kettle body and a jacket outside the kettle body to keep the material temperature within the required range for the material reaction. The shaft sealing device is the seal between the stirring tank and the stirring shaft to prevent the overflow of reaction materials and the infiltration of other impurities.

The fermentation tank needs to keep the tank clean and hygienic when it is working. In order to make the fermentation bacteria ferment well during the reaction process, it is necessary to maintain a constant temperature; the agitator stirs the materials to make the materials mixed evenly. Speed up the reaction speed and shorten the fermentation cycle.

Microbial fermentation tanks generally need to meet these basic requirements: suitable diameter-to-height ratio, can withstand a certain pressure, break bubbles and mix well, good circulating cooling and heating system, inner wall polishing, not easy to have dead ends, tight shaft seal, and transmission High efficiency and low energy consumption are required.
