(1) The outstanding difference between fermentation tank and other industrial equipment is the high requirements for pure culture, which almost reaches a very demanding level. Therefore, the tightness of fermentation tanks and the high reliability of operation are the significant characteristics of the fermentation industry.
(2) In order to obtain greater economic benefits, the modern fermentation industry has become more large-scale and automated. In terms of automation of fermentation tanks, the online detection of parameters such as pH electrode, dissolved oxygen electrode, dissolved CO2 electrode, etc. has been quite mature abroad. The fermentation detection parameters are also limited to some of the most conventional parameters, such as temperature, pressure, air flow, etc.
