Fermentation tank is suitable for pharmaceutical, biological, beverage, food, chemical and other industries. It is a device specially used for microbial fermentation in industrial places. Its appearance has brought a lot of help to our life. The structure and design of the whole machine have been professionally designed, so there is no need to worry about cleaning and maintenance during use, and it can be carried out very simply. Let’s talk about the basic structure of the fermentation tank:
- Dissolved oxygen control system:
(1) Air flow meter: manually adjust the dissolved oxygen level in the fermentation broth by adjusting the air flow;
(2) Stirring motor and stirring linkage: The stirring motor of the fermentation tank provides the power to rotate, Drive the stirring linkage to rotate; the latter blade stirs the fermentation liquid, disperses the bubbles, increases the contact interface of the gas and liquid, and thus increases the dissolved oxygen level.
2. Tank body: The volume of the fermenter used in the laboratory is generally several liters and tens of liters, and the tank body is usually composed of glass.
3. Detection device: The detection device of a typical fermentation tank is:
(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, Changes in pH in the fermentation broth were monitored.4. Temperature control system: including the cooling water pipe at 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 in to maintain a constant temperature.
5. Acid-base balance device: The acid or alkaline solution can be pumped into the fermentation broth through the peristaltic pump to adjust its pH value.
(1) Inoculation port: insert the seed liquid into the fermenter through the inoculation port, and supplement nutrients during the fermentation process at the same time;
(2) Sampling port: through the sampling port, a certain amount can be taken out of the fermenter fermentation broth for various detection and analysis.
