The following six basic structures of a fermentation tank are indispensable

Fermentation tank is suitable for pharmaceutical, biological, beverage, food, chemical and other industries. It is a device used for microbial fermentation in industrial places. Its appearance has brought a lot of help to our lives. The structure and design of the whole machine are professionally and specially designed. It is easy to carry out without worrying about cleaning and maintenance. Let’s talk about the basic structure of the fermentation tank:

1. Dissolved oxygen control system:
(1) Air flow meter: manually adjust the dissolved oxygen level in the fermentation broth by adjusting the amount of air flow;
(2) Stirring motor and stirring linkage device: The stirring motor of the fermentation tank provides rotating power, which drives the stirring linkage device to rotate; the blades of the latter stir the fermentation broth, break up the air bubbles, increase the contact interface between gas and liquid, and thereby increase the dissolved oxygen level.

2. Tank body: The volume of laboratory fermentation tanks is generally several liters to tens of liters. The tank body is usually composed of glass.

3. Detectors: Detectors of typical fermentation tanks are available.
(1) Temperature probe: monitor the temperature change during the cultivation process;
(2) Dissolved oxygen electrode: directly immersed in the fermentation broth to monitor the change of dissolved oxygen in the fermentation broth;
(3) pH electrode: directly immersed in the fermentation broth to monitor the pH change in the fermentation broth.

4. Temperature control system: Including the cooling water pipe on the bottom of the fermentation tank and the cooling water pipe on the condenser at the air outlet. Since heat is usually generated during the fermentation process, cooling water can be passed to maintain a constant temperature.

5. Acid-base balance device: The acid or alkaline solution can be pumped into the fermentation broth through a peristaltic pump to adjust its pH value.

6. Other devices:
(1) Inoculation port: the seed liquid is inserted into the fermentation tank through the inoculation port, and nutrition can also be added during the fermentation process;
(2) Sampling port: Through the sampling port, a certain amount of fermentation liquid can be taken out of the fermentation tank for various detection and analysis.
