Second hand 200 liter biological fermentation tanks are widely used in industries such as food, medicine, and chemical engineering, such as in the food industry for producing alcoholic beverages, yogurt, etc; Used in the pharmaceutical industry for the production of antibiotics, vitamins, etc; Used in the chemical industry for the production of amino acids, enzyme preparations, etc.
A biological fermentation tank is an industrial device used for microbial fermentation. The following is a detailed introduction about it:
Classification based on microbial growth and metabolic requirementsIt can be divided into aerobic fermentation tanks and anaerobic fermentation tanks. Aerobic fermentation tanks are used for fermentation processes that require oxygen participation, such as antibiotic and amino acid production; Anaerobic fermentation tanks are used for fermentation in anaerobic or low oxygen environments, such as alcohol and biogas production.
Classified by the state of the culture mediumIncluding solid fermentation tanks and liquid fermentation tanks. Solid fermentation tanks are used for solid-state medium fermentation, such as shallow tray fermentation tanks and rotary drum fermentation tanks; Liquid fermentation tanks are widely used for liquid medium fermentation, such as mechanical stirring fermentation tanks, bubble fermentation tanks, etc.
Classified by device structureThere are vertical fermentation tanks, horizontal fermentation tanks, tubular fermentation tanks, and tower fermentation tanks. The vertical fermentation tank has a high height and a small footprint; Horizontal fermentation tank has a low center of gravity and good stability; The tubular fermentation tank is composed of pipes and has a large specific surface area; Tower fermentation tanks have a multi-layer structure and are suitable for co cultivation of various microorganisms.
Classified by mixing formIt can be divided into mechanical stirring fermentation tanks, bubble fermentation tanks, and liquid circulation fermentation tanks. Mechanical stirring fermentation tanks are stirred by agitators, such as ventilated and self-priming fermentation tanks; The bubble fermentation tank is stirred with the help of air blowing; Liquid circulation fermentation tanks, such as air lift fermentation tanks, use air to rise and circulate the fermentation broth.
Mechanical stirring fermentation tankMainly composed of tank body, agitator, baffle, shaft seal, air distributor, transmission device, cooling device, defoaming device, etc. The tank body is cylindrical, the agitator is usually turbine or propeller type, the baffle is used to enhance the stirring effect, and the shaft seal prevents leakage and impurities from entering.
Airlift fermentation tankIt mainly consists of a tank body, an ascending pipe, a descending pipe, an air distributor, a guide tube, etc. The riser and downcomer are the core components that form a fermentation liquid circulation through air action, and the flow direction of the fermentation liquid is guided by a guide tube.
Tower fermentation tankGenerally cylindrical in shape, with a higher height and a relatively smaller diameter. Multiple layers of sieve plates or fillers are installed inside the tank, and the air distributor is located at the bottom of the tank. There are exhaust outlets and condensers at the top of the tower.
Mechanical stirring fermentation tankBy rotating the mixer, the fermentation broth is thoroughly mixed to ensure even distribution of nutrients and oxygen. At the same time, the shear force of the mixer breaks the bubbles, improving the efficiency of oxygen transfer. Air enters the tank through the air distributor.
Airlift fermentation tankUtilize the rising effect of air to create a circulating flow of fermentation broth in the ascending and descending pipes. Air enters the riser and mixes with the fermentation broth. The density of the gas-liquid mixture decreases and flows upwards. After separation at the top, the fermentation broth enters the downcomer and flows downwards under the action of gravity, achieving mixing and oxygen transfer.
Tower fermentation tankBy using air to rise, the fermentation broth forms a liquid film on the sieve plate or packing, which fully contacts with the air to achieve oxygen transfer and carbon dioxide discharge. The fermentation broth flows from the upper layer to the lower layer under the action of gravity, while air enters from the bottom and comes into counter current contact with the fermentation broth.
Efficient mixing and mass transferEquipped with a stirring system or utilizing air circulation to evenly distribute nutrients and oxygen, improving fermentation efficiency.
Precise control of temperature and pHHigh precision sensors are used to monitor temperature and pH values in real-time, equipped with efficient heating and cooling devices that can respond quickly and adjust accurately.
Good sealing and sterile operationAdopting high-quality sealing materials and structural design to prevent gas leakage and microbial invasion, with a complete sterilization system and sterile operation interface.
High degree of automation control: It can set and adjust parameters through computer programs, record and analyze data in real time, and has automatic alarm and fault diagnosis functions.
Diversified tank designThere are fermentation tanks for small laboratories and large industrial production, and the tank material can be selected from stainless steel, glass, etc.
Easy to maintain and cleanReasonable structural design, easy to disassemble, install, and replace internal components, smooth surface, and easy to clean and disinfect.
Widely used in industries such as food, medicine, and chemical, such as in the food industry for producing alcoholic beverages, yogurt, etc; Used in the pharmaceutical industry for the production of antibiotics, vitamins, etc; Used in the chemical industry for the production of amino acids, enzyme preparations, etc.
