Description

(1) Technical field

[0001] The invention relates to a disinfection and sterilization technology, in particular to a new method for disinfection and sterilization of fermenters in use. (2) Technical background

[0002] In the traditional fermentation process, such as glutamic acid, glutamine, lysine and other fermentation products, in order to ensure the smooth progress of the fermentation process and eliminate the contamination and economic losses caused by equipment, the continuous disinfection and sterilization method of fermentation broth is required The fermenter is cleaned with lye before feeding each batch, and then sterilized by steam and high pressure. This sterilization method not only consumes a lot of steam, but also has more non-production time of the equipment, and the utilization rate of the equipment is low. (3) Contents of the invention

[0003] The technical task of the present invention is to provide a fermentation tank disinfection and sterilization meth...
