Product Description

Precautions
1) Before sterilizing the vessel, be sure to check the liquid level; all electrodes must be fully submerged below the liquid surface.
2) Before turning on the fermenter’s power, be sure to verify that the cooling water is activated and that the temperature probe is properly inserted into the vessel; otherwise, the heating circuit may be damaged.
3) During the fermentation process, it is essential to maintain a clean workbench; promptly clean up used culture flasks and other materials, and immediately wipe up any acid or alkali solutions or water that may have been spilled.
4) During installation, disassembly, and sterilization of the vessel, exercise extreme caution with the pH electrode and other fragile, costly components of the vessel.

Structural Composition
Fermentation tanks are widely used in industries such as beverages, chemicals, food, dairy, seasonings, brewing, and pharmaceuticals to facilitate fermentation. The main components of a fermentation tank include: the vessel, which is primarily used to cultivate various microbial strains and must maintain excellent sealing to prevent contamination; an agitator impeller inside the vessel, which continuously stirs the culture during fermentation; an air‑sparging device at the bottom, supplying the air or oxygen required for microbial growth; and control sensors mounted on the top head—most commonly pH and dissolved‑oxygen (DO) electrodes—to monitor changes in the fermentation broth’s pH and DO levels. A controller is employed to display and regulate fermentation conditions. Based on their design, fermentation tanks are classified into mechanically stirred, aerated types and non‑mechanically stirred, aerated types; and according to the metabolic requirements of the microorganisms, they are further divided into aerobic and anaerobic fermentation tanks.
