Fermentation tank definition:
Fermentation tank refers to an industrial device used for microbial fermentation.
Its main body is usually a main cylinder made of stainless steel plate, with a volume ranging from 1m3 to several hundred m3.
Attention should be paid to the tight and reasonable structure in design and processing.
It can withstand steam sterilization, has certain operational flexibility, minimizes internal accessories (avoiding dead corners), has strong material and energy transfer performance, and can be adjusted for easy cleaning and pollution reduction. It is suitable for the production of various products and reduces energy consumption.

The purpose of the dry white hair fermentation jar is:
The structure of the fermentation tank used for anaerobic fermentation (such as producing alcohol and solvents) can be relatively simple.
Fermentation tanks used for aerobic fermentation (such as the production of antibiotics, amino acids, organic acids, vitamins, etc.) require continuous introduction of a large amount of sterile air into the tank, and to consider the utilization rate of the introduced air, the structure of the fermentation tank is relatively complex. Commonly used fermentation tanks include mechanical stirring fermentation tanks, bubble fermentation tanks, and gas lift fermentation tanks.
The fermentation process of dairy products and alcoholic beverages is a sterile and pollution-free process. The fermentation tank adopts a sterile system to avoid and prevent microbial contamination in the air, greatly extending the shelf life and purity of the product. The tank is specially designed and installed with sterile breathing holes or a sterile positive pressure fermentation system.
The tank is equipped with a Milo plate or a labyrinth jacket, which can be heated or cooled by circulating a heating or cooling medium.
The capacity of fermentation tanks varies from 300-15000L in different specifications.
Fermentation tanks can be divided into laboratory dry white fermentation tanks, pilot production fermentation tanks, large-scale fermentation tanks, etc. according to their usage scope.
Fermentation tanks are widely used in industries such as dairy products, beverages, biotechnology, pharmaceuticals, and fine chemicals. The tank body is equipped with a sandwich layer, insulation layer, and can be heated, cooled, and insulated.
The tank body and upper and lower filling heads (or conical shapes) are both processed by spinning R angles, and the inner wall of the tank is polished with a mirror finish to ensure no hygiene dead corners. The fully enclosed design ensures that the materials are always mixed and fermented in a pollution-free state. The equipment is equipped with air breathing holes, CIP cleaning nozzles, manholes, and other devices.
Classification of fermentation tanks: According to the equipment of the fermentation tank, it is divided into mechanical stirring and ventilation fermentation tanks and non mechanical stirring and ventilation fermentation tanks; According to the growth and metabolic needs of microorganisms, they are divided into aerobic fermentation tanks and anaerobic fermentation tanks.
A fermentation tank is a device that mechanically stirs and ferments materials.
This device adopts an internal circulation method, using a stirring blade to disperse and crush bubbles. It has a high dissolved oxygen rate and good mixing effect.
The tank body is made of imported stainless steel SUS304 or 316L, and is equipped with an automatic spray cleaning machine head to ensure that the production process meets GMP requirements.

The structural characteristics of the dry white hair fermentation tank:
1. It can be cleaned online with CIP and sterilized with SIP (121 ° C/0.1MPa).
2. Designed according to hygiene requirements, the structural design is humanized and easy to operate. Smooth transmission and low noise.
3. Suitable diameter to height ratio design, customized mixing device according to needs, energy-saving, good mixing and fermentation effects.
4. Mirror polishing treatment on the surface of the inner tank body (roughness Ra ≤ 0.4 μ m); m) The process openings such as inlet and outlet pipes, sight glasses, manholes, etc., and the welding points of the inner tank body are all made of stretch flanging process arc transitions, which are smooth and easy to clean without dead corners, ensuring the reliability and stability of the production process and meeting the requirements of "cGMP" and other specifications.

The main components of the dry white hair fermentation tank are:
Tank body: mainly used for cultivating and fermenting various bacterial cells, with good sealing (to prevent bacterial contamination)
There is a stirring slurry in the tank, which is used for continuous stirring during the fermentation process
Sparger with bottom ventilation, used to introduce air or oxygen required for bacterial growth
There are control sensors on the top plate of the tank, commonly used including pH electricity and DO electricity, used to monitor the changes in pH and DO of the fermentation broth during the fermentation process. The controller is used to display and control the fermentation conditions, and so on.

Instructions for using a dry white hair fermentation jar:
1) Correct pH and dissolved oxygen electricity.
2) Sterilization of tanks. Add the culture medium into the tank as needed, seal it as required, and place the 5L dry white fermentation tank in a large sterilization pot for sterilization (115 ℃, 30 minutes); Large fermentation tanks (10L and above) are sterilized with steam (121 ℃, 30min).
3) 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、 Mixing speed, etc., and calibrating the slope of dissolved oxygen electricity at a determined speed and ventilation rate, with a value of
4) After the temperature stabilizes and all parameters are correct, connect the pre shaken seeds, start fermentation timing, and start recording various parameters.
5) After fermentation is complete, clean the tank and the electricity. Insert the pH electricity into a triangular flask containing 3M potassium chloride for later use. Cover the probe for dissolved oxygen electricity with a protective sleeve and store it for later use.
