The fermentation tank structure used for anaerobic fermentation (such as producing alcohol and solvents) can be relatively simple. The fermentation tank used for aerobic fermentation (such as the production of antibiotics, amino acids, organic acids, vitamins, etc.) is complex in structure due to the need to continuously introduce a large amount of sterile air into the tank and to consider the utilization rate of the air. Commonly used types include mechanical stirring fermentation tanks, bubble fermentation tanks, and airlift fermentation tanks.

The fermentation process of dairy products and alcoholic beverages is a sterile and pollution-free process. The fermentation tank adopts a sterile system to avoid and prevent microbial contamination in the air, greatly extending the shelf life and product quality. The tank body is specially designed and installed with sterile breathing holes or a sterile positive pressure fermentation system. The tank body is equipped with a Milo plate or maze type jacket, which can be fed with heating or cooling media for cyclic heating or cooling. The capacity of the fermentation tank varies from 300-15000L to various specifications. Fermentation tanks can be divided into laboratory small fermentation tanks, pilot production fermentation tanks, large fermentation tanks, etc. according to their scope of use.

Fermentation tanks are widely used in industries such as dairy products, beverages, bioengineering, pharmaceuticals, and fine chemicals. The tank body is equipped with a interlayer, insulation layer, and can be heated, cooled, and insulated. The tank body and the upper and lower filler heads (or cones) are processed by spinning the R angle. The inner wall of the tank is Bull polishing without sanitary dead corners. The fully enclosed design ensures that the materials are always mixed and fermented in a pollution-free state. The equipment is equipped with air breathing holes, CIP cleaning nozzles, manholes and other devices.

Classification of fermentation tanks: According to the equipment of fermentation tanks, they are divided into mechanical stirring ventilation fermentation tanks and non mechanical stirring ventilation fermentation tanks;

According to the growth and metabolism needs of microorganisms, they are divided into aerobic fermentation tanks and anaerobic fermentation tanks.

A fermentation tank is a device for mechanically stirring and fermenting materials. This equipment adopts an internal circulation method, using a stirring paddle to disperse and crush bubbles. It has a high oxygen dissolution rate and good mixing effect. The tank body is made of SUS304 or 316L imported stainless steel, and the tank is equipped with an automatic spray cleaning machine head to ensure that the production process meets GMP requirements.
