 Describe

This kind of fermentation tanks and seeding tanks are made from carbon steel, stainless steel, high nickel-based alloys and so on, and they are mainly used for biochemistry fermentation production, such as the production of monosodium glutamate, citric acid, enzyme preparations, solvents for pharmaceutical, food and other industries. This product is designed according to the petroleum products, chemicals, a machine of the. In addition, as the main parameter for reference, GB150-2011is used to manufacture, inspect and accept this tank.

I. The Basic Conditions for Fermentation Tanks

The mechanical agitation fermentation tank is one of the common types used in the fermentation plant. It uses mechanical agitators to completely mix air and the mash, and make the oxygen dissolved in the mash, which guarantees the enough supply of oxygen for microbial growth, reproduction and fermentation. Several basic requirements needed to make fermentation tanks as followed: 
1.Fermentation tanks should have suitable scale of diameter to height, which is generally about 1.7 to 4, the longer the tanks are, the higher the utilization rate of oxygen will be.
2.Fermentation tanks can bear certain pressure. When fermentation tanks are normally working or being disinfected, there will certain pressure (hydraulic pressure and pneumatic pressure) and temperature in the tanks, so all of their components must have certain strength to bear the pressure.
3.The stirring and ventilating device in fermentation tanks make the gas and the liquid fully mixed to make sure that the fermentation broth must dissolve oxygen.
4.Fermentation tanks should have sufficient cooling area. In the process of microbial growth and metabolism, it will release a lot of heat. So in order to control the temperatures on different stages in the fermentation process, it should be equipped with adequate cooling area.
5.Fermentation tanks must minimize dead corners to avoid accumulation of dirt, so it can be thoroughly sterilized to avoid bacterial contamination.
6.The seal of agitators should be tight to minimize leakage.

II. The Size Scale of Fermentation Tanks
There is a certain scale of the size of each part of the tank. The scale of height to diameter of the tank is about 1.7 to 4.
Fermentation tanks usually are equipped with two sets of agitators. The distance between the two sets of agitators (S) is about three times as the diameter of the agitator. For large-scale fermentation tanks or those that have high liquid depth (HL), they can install three or more sets of agitators. It will be better if the agitator at the bottom is close to the exit of air dust, and the distance to the bottom of the tank (C) equals to the diameter of the agitator (Di), but could not be less than 0.8 times of Di, otherwise it will affect the cycle of liquid.

III、The Structure of Fermentation Tanks
An aerobic mechanical agitation fermentation tank is sealed compression equipment. Its main components include the tank, agitator, seal, a bubbler, couplings, intermediate bearings, air blowing pipe (or air ejector), baffle, cooling device, manhole, pipeline, etc.
