Tank body: Generally made of stainless steel materials such as 304 and 316L, it has good corrosion resistance and hygienic properties and can withstand certain pressure and temperature.
Agitating device: It includes an agitating shaft, agitating paddles and so on. Its function is to fully mix the culture medium and microbial strains, improve the transfer efficiency of nutrients, and promote the growth and metabolism of microorganisms. For liquid fermentation tanks, the agitating device is particularly important. Appropriate forms of agitating paddles and rotational speeds can be selected according to different fermentation requirements.
Heating and cooling devices: In order to meet the temperature requirements for the growth of microorganisms, the microbial culture tank is usually equipped with heating and cooling devices. Common heating methods include steam heating, electric heating, etc., while cooling methods include jacket cooling, coil cooling, etc. By controlling the temperature, the growth of microbial strains in a suitable environment can be ensured.
Aeration system: Aerobic fermentation tanks need an aeration system to provide sterile air, including air filters, air distributors and so on. The air filter is used to remove impurities and microorganisms in the air to ensure that the air entering the tank is sterile; the air distributor evenly distributes the sterile air into the fermentation broth to improve the dissolved oxygen efficiency.
Monitoring and control system: Equipped with temperature sensors, pH sensors, dissolved oxygen sensors, etc., it can monitor and control key parameters in the fermentation process in real time, such as temperature, pH value, dissolved oxygen content, etc., ensuring the stability and controllability of the fermentation process.
Inlet and outlet ports: The inlet port is used for adding the culture medium and microbial strains, while the outlet port is used for discharging the products after fermentation and the residual culture medium.
