Multistage biological fermentation system

Abstract

The invention discloses a multistage biological fermentation system. One end of a first-stage feeding pipeline extends to the bottom in a first-stage fermentation tank from a feeding hole in the upperpart of the first-stage fermentation tank; one end of a second-stage feeding pipeline is communicated with a discharging hole in the bottom of the first-stage fermentation tank; the other end of thesecond-stage feeding pipeline penetrates through a feeding hole in the upper part of the second-stage fermentation tank and extends to the bottom in the second-stage fermentation tank; one end of a third-stage feeding pipeline is communicated with a discharging hole in the bottom of the second-stage fermentation tank; the other end of the third-stage feeding pipeline penetrates through a feeding hole in the upper part of the third-stage fermentation tank and extends to the inner bottom of the third-stage fermentation tank; a return pipeline and a discharge pipeline are respectively arranged ata discharging hole in the bottom of the third-stage fermentation tank; and the other end of the return pipeline is communicated with a feeding hole in the upper part of the second-stage fermentationtank. According to the system, multi-stage automatic continuous culture is realized, the production efficiency is improved, and each stage of fermentation tank is designed according to the fermentation conditions of each stage of fermentation stage, so that each stage of fermentation effect reaches the optimal state.

Description

technical field [0001] The invention relates to the technical field of biological fermentation equipment, in particular to a multi-stage biological fermentation system. Background technique [0002] Fermentation tank refers to the device used in industry for microbial fermentation. It replaces the traditional fermentation container. Compared with the traditional container, it has more obvious advantages: it can carry out strict sterilization in all directions before use, Air, to ensure sufficient dissolved oxygen, maintain a constant pressure, temperature and PH value to provide a good fermentation environment for microorganisms, and also implement stirring and other measures to promote the growth of microorganisms. [0003] However, in the large-scale continuous production process of microorganisms, microorganisms usually need to go through at least three different fermentation stages, and the fermentation process parameters in each fermentation stage are different. In the...

Problems solved by technology

In the prior art, it is usually necessary to manually replace the fermenter according to the degree of fermentation in the fermenter, which takes a long time and has low production efficiency, which seriously restricts its large-scale production, and the function of each stage of fermenter is relatively single, and only the setting is simple. The stirring device is not designed according to the characteristics of microbial fermentation in each stage, and the fermentation effect in the fermentation tanks at all levels is limited, which affects the final fermentation effect and fermentation efficiency
