The structure characteristics and development trend of the application field of strain fermenter

The tank body of the structure is provided with interlayer, thermal insulation layer, which can be heated, cooled and insulated. The tank body and upper and lower filling head (or prototype) are processed by spinning R Angle, the inner wall of the tank is polished by mirror, and there is no sanitary dead Angle.

The structure adopts the above fully closed design to ensure that the material is always in a non-polluting state of mixing and fermentation. The equipment is equipped with air breathing hole, CIP cleaning nozzle, manhole, inlet and outlet and other devices.

In recent years, with the continuous progress of science and technology, the fermentation industry, which is related to the national economy and people's livelihood, has made rapid development, and the fermentation equipment has also been updated from tradition to modernization.

In China, it can be divided into mechanical stirred and ventilated fermentation tanks and non-mechanical stirred and ventilated fermentation tanks. According to the growth and metabolism needs of microorganisms, it can be divided into good gas fermentation tanks and anaerobic fermentation tanks. We often refer to the strain fermenter is a stirred and ventilated fermentation equipment.

The structure of strain fermenter used for anaerobic fermentation (such as producing alcohol and solvent) can be simpler. The requirements for the fermenter of this kind of strain are: it can be closed; Able to work under pressure; There is cooling equipment; Reduce the device in the tank as much as possible, eliminate dead corner, easy to clean and sterilize. Alcohol and beer are both anaerobic fermentation products, and their strain fermenters do not need to be filled with expensive sterile air, so they are much simpler to enlarge, manufacture and operate than aerobic fermentation equipment.

For aerobic fermentation (such as antibiotics, amino acids, organic acids, vitamins, etc.) of the strains fermentation tank to tank for continuous access to a large number of sterile air, and to consider going into the air utilization ratio and so on bacteria fermentation tank structure is relatively complex, the commonly used mechanical agitator strains fermentation tank, fermentation tank and air bubble type strains type strains fermentation tank.

Installation requirements

The fermentation equipment has been fixed with a bracket, as long as the bracket is placed on the flat cement floor. The agitator motor is powered by 380V three-phase power and requires professional installation. Use the appropriate cable from the motor terminal to the designated terminal of the electric control box, and finally connect the main power supply to the designated terminal of the electric control box.

Precautions for Use

1. Firstly, check whether the power supply is connected and whether there is leakage of electricity. During operation, wipe the hands dry, do not bring water to prevent electric shock.

2. After use, the power should be cut off first, and tap water should be added to the tank immediately, so as to extend the service life of the fermentation tank.

3. When cleaning the equipment, do not use the steel tool to scratch, so as not to scratch the tank body.

4, like all stainless steel containers, the tank should be stored basically without chlorine ion liquid materials, in addition is strictly prohibited to have obvious chloride ion storage environment.
