(1) The difference between the fermentation tank and other industrial equipment is that the requirement of purebred culture is high, and the degree is almost very harsh. Therefore, the rigor of the fermentation tank and the high reliability of the operation are the notable characteristics of the fermentation industry.
(2) Modern fermentation industry in order to obtain greater economic benefits, the fermentation tank more tend to large-scale and automatic development. In the automation of fermentation tank, on-line detection of the eyes such as ph electrode, dissolved oxygen electrode, dissolved CO2 electrode and so on are quite mature abroad. Fermentation testing parameters are also limited to temperature, pressure, air flow, and some of the most conventional parameters.
