Fermentation tank refers to the equipment used in industry for magnetic biological fermentation. Its main body is generally a main type face cylinder made of stainless steel plate, with a capacity of 1m3 to several hundred cubic meters. In the design and processing, attention should be paid to tight and reasonable plum formation, which can withstand steam sterilization, have flexible operation, minimize internal accessories (avoid dead corners), have strong material and energy transfer performance, and can be adjusted in one go for cleaning and pollution reduction. It is suitable for the production of various products and reduces energy consumption.

structure
Material: Made of stainless steel, acid resistant, alkali resistant, and corrosion-resistant;
Components: tank body, shaft seal, agitator, defoamer, coupling, intermediate bearing, baffle, gas distributor, heat exchange device, manhole, sight glass, etc;
Transmission device: commonly used as gear reducer and pulley reducer;
Blender forms: wide blade high-efficiency axial flow, disc turbine mixing and other combination gas distributors:
Heat transfer form: Small tanks are generally equipped with integral jackets, while medium-sized fermentation tanks are equipped with several sets of vertical serpentine tubes, inner coil tubes, or outer half tubes; Large fermentation tanks are used in combination with coil and outer half tubes;
working principle
① Correct pH electrode and dissolved oxygen electrode.
② Sterilization of tanks. Add the culture medium into the tank as needed, seal it as required, and place the small fermentation tank (5L) in a large sterilization pot for sterilization (115 ℃, 30 minutes); Large fermentation tanks use steam sterilization
(121 ℃, 30min).
⑧ After the tank has cooled down, place it on the fermentation platform and install it properly; Turn on the cooling water, turn on the power of the air pump, connect the ventilation pipe to start ventilation, adjust the intake knob to adjust the ventilation volume appropriately, and keep the tank pressure at 0.05MPa; Set temperature, pH, stirring speed, etc., and calibrate the slope of the dissolved oxygen electrode at a determined speed and ventilation rate;
characteristic
Suitable aspect ratio can be designed according to the fermentation process
Good mixing characteristics of gas, liquid, and solid can disperse and finely crush bubbles to ensure the dissolution rate of oxygen;
The polishing accuracy of the inner surface is Ra<0.4um, smooth and easy to clean without dead corners, ensuring thorough sterilization;
Has good heat exchange performance to maintain the optimal temperature for biological reactions.
Scope of application
Amino acids lysine and succinic acid
Polysaccharides: Xanthan gum, Gellan gum
Antibiotics, insulin, penicillin in the pharmaceutical industry
Vitamins. Ascorbic acid, vitamin C, vitamin B12
Biofuel: Bioethanol
