Structural composition of fermentation tank

Fermentation tanks are widely used in beverage, chemical, food, dairy, seasoning, brewing, pharmaceutical and other industries, and play a role in fermentation. The composition of fermentation tank includes: the tank is mainly used for cultivating and fermenting various thalli, with good sealing (preventing thalli from being polluted), and there is stirring slurry in the tank, which is continuously stirred during fermentation; The bottom-ventilated sprayer is used to introduce air or oxygen needed for bacterial growth. The top plate of the tank is equipped with control sensors, the most commonly used are pH electrodes and DO electrodes, which are used to monitor the changes of pH and DO in the fermentation broth. The controller is used to display and control fermentation conditions. According to the equipment of fermentor, it can be divided into mechanical stirring aeration fermentor and non-mechanical stirring aeration fermentor. According to the needs of microbial growth and metabolism, it can be divided into aerobic fermentation tank and anaerobic fermentation tank.
