Fermentation system and method

Abstract

A fermentation system comprises a plurality of seed tanks with different capacities, seed transferring pipes, a plurality of fermentation tanks and discharging pipes, wherein the seed transferring pipes are connected with the seed tanks, that is, the seed tanks are sequentially connected through the seed transferring pipes, the seed tanks are sequentially arranged from small to large according to capacities of the seed tanks, the discharging pipes are connected with the fermentation tanks, fermentation broth can be transported between the fermentation tanks through the discharging pipes, and the seed transferring pipe is also connected with one fermentation tank, that is, the seed tank with the maximum capacity is connected with one fermentation tank through the seed transferring pipe, so that mature seeds are conveyed into the fermentation tank from the seed tank. The fermentation system reduces empty disinfection of seed tanks, actual disinfection times after culture medium is added and sterilization times of seed transferring pipes, effectively reduces pollution of cultivation operation, saves energy consumption such as steam, electricity and water, and correspondingly reduces primary and secondary seed culture medium, thereby reducing production cost. The invention also provides a fermentation method.

Description

technical field [0001] The invention relates to the technical field of lactic acid fermentation, in particular to a fermentation system and method. Background technique [0002] Fermentation refers to the process of preparing the microbial cell itself, or direct metabolites or secondary metabolites by means of the life activities of microorganisms under aerobic or anaerobic conditions. [0003] In the prior art, the cultivation and fermentation of seeds are completed through seed tanks and fermenters, please refer to figure 2 , wherein several seed tanks are connected sequentially, and finally a fermenter is connected, that is, several seed tanks correspond to one fermenter. The seeds are transplanted into the fermenter for fermentation, and the seed tank and fermenter must be emptied and sterilized before seed cultivation and fermentation; [0004] In the actual production process, in order to meet the production requirements, multiple sets of seed tanks and fermentation ...

AI Technical Summary

Problems solved by technology

[0004] In the actual production process, in order to meet the production requirements, multiple sets of seed tanks and fermentation tanks are needed to cultivate and ferment the seeds to improve production efficiency. The increase in the number of seed tanks and fermentation tanks not only increases the number of sterilizations, but also increases the configuration. The use of raw and auxiliary materials leads to an increase in production costs, and the increase in seed tanks is likely to cause
