The tank type of nickel tank fermentation equipment can be divided into two categories: one is the cone type of anaerobic fermentation (such as alcohol fermentation), the other is the tank type of anaerobic fermentation (such as standard type, Wu type, self-priming type, etc.). This kind of equipment is most commonly used in the standard tank type. The drawings and data of fermentation tank series belong to standard tank type. In the design of various specifications of fermentation equipment, the design structure shall be tight, with sufficient strength and service life, and the internal accessories of the equipment shall be few and the surface shall be smooth. It is noted that good gas contact and gas stab solid mixing performance shall be provided, so as to effectively carry out material transfer and gas exchange. There is enough heat exchange area to ensure that the fermentation can be carried out at the most appropriate temperature. Pay attention to the sealing performance of the equipment to ensure the sterilization operation.
