The new technology of energy-saving fermenter and the height-diameter ratio of fermenter
The new technology of energy-saving fermenter and the height-diameter ratio of fermenter
With the development of glutamic acid production in energy-saving fermenter, new technology and technology have been adopted. In particular, glutamic acid fermentation using a large amount of species, large air volume, continuous tank fed sugar fermentation process. The traditional fermenter is not enough to meet the requirements of the new fermentation process. It also does not meet the need of energy-saving and consumption-reducing fermentation production. Fermenter height: appropriate fermentation liquid column, so that air in the fermentation liquid has a certain residence time, can improve the dissolved oxygen in the liquid, conducive to fermentation acid. But with the development of fermentation column. The inlet air pressure of fermenter should be improved. And the inlet pressure should be greater than the fermentation liquid column static pressure plus fermenter pressure, so the air compressor outlet pressure also progress, power consumption increases; The power consumption increases relatively, and the tank is not chaotic reduction, easy to shake. The height of the fermentation plant is increased and the cost is higher. In recent years, the volume of newly built fermenters tends to be large, ranging from 100 to 250,660 or even larger. But overall consideration, fermenter straight stab height should not be too high, to not more than 14 m is appropriate.
