fermentation tank

It is usually considered a bioreactor, which is a special biological reaction process that provides a good and satisfactory environment for the operation of fermentation. In some manufacturing processes, the sterilization fermentation tank is a closed container equipped with a precision control system; Fermentation tanks are important equipment in fermentation production and are used in industries such as chemical and food. Generally speaking, fermentation mainly refers to industrial fermentation, which generally refers to the process of using biological cells to produce a certain product or purify the environment. The production process includes anaerobic cultivation of alcohol, acetone, butanol, lactic acid, as well as aeration (aerobic) cultivation of antibiotics, amino acids, enzyme preparations, etc. This product not only contains cellular metabolites, but also includes bacterial cells, enzymes, etc. Therefore, fermentation tanks are the site of biological fermentation reactions.

There are various types of sterilization fermentation tanks, such as (1) mechanical stirring fermentation tank, (2) bubble fermentation tank, (3) liquid circulation fermentation tank, etc.

Today, the editor will take you to learn about mechanical stirring fermentation tanks.

Mechanical stirring fermentation tanks can be divided into ventilated fermentation tanks, self-priming fermentation tanks, etc. Mechanical stirring ventilated fermentation tanks are commonly used in fermentation equipment. Mechanical agitation and ventilation fermentation tank is a sealed pressure equipment, whose main components include tank body, shaft seal, defoamer, agitator, coupling, intermediate bearing, baffle, air supply pipe, heat exchanger, wellbore, pipeline, etc.

1. Ventilated fermentation tank: Ventilated fermentation tank, also known as universal fermentation tank, is a commonly used microbial reactor in industry. Its advantage is that the pH value and temperature of the fermentation broth are easy to control, making it suitable for continuous cultivation. The disadvantage is that cells are easily damaged during the cultivation of filamentous bacteria.

2. The self-priming fermentation machine does not require an air compressor to supply compressed air. The self-priming fermentation machine uses negative pressure generated by a stirrer to suck in air. Its advantage is that both stirring and air supply are completed by a mechanical stirrer. The disadvantage is that the suction range is not high, and fermentation with high sterile requirements is not suitable because air enters the fermenter during stirring, which is not suitable for anaerobic fermentation.
