A kind of horizontal continuous fermentation system and continuous fermentation method

Abstract

The invention discloses a horizontal continuous fermentation system, comprising: a first fluid, the conveying pressure and interval of the first fluid can be adjusted; a fermentation container; auxiliary equipment, the auxiliary equipment is suspended in the fermentation container, and a plurality of auxiliary equipment They are arranged parallel to each other in the height direction of the fermentation container. The auxiliary equipment includes an auxiliary board, a luminous part fixed to the auxiliary board and bristles. The auxiliary board is made of transparent material, and the bristles are arranged on the surface of the auxiliary board. distance between devices. This fermentation system is suitable for the continuous fermentation of microorganisms. It can realize the self-swaying of the auxiliary equipment in the fermentation container through the first fluid continuously input at intervals, and realize the stirring of the liquid in the fermentation container, reduce the aggregation and precipitation of microorganisms, make it receive light evenly, and promote its reproduce.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to microbial fermentation in food and feed, and in particular to a horizontal continuous fermentation system and a continuous fermentation method. Background technique [0002] Photosynthetic bacteria (Photo Synthetic Bacteria, referred to as PSB) is the earliest prokaryotic organism with a primitive light energy synthesis system on the earth. It is a general term for a large class of bacteria that perform photosynthesis without oxygen release under anaerobic conditions. Paddy fields, lakes, rivers, oceans, activated sludge and soil. At present, the photosynthetic bacteria of Rhodospiraceae are used more, especially the species of Rhodopseudomonas. [0003] Photosynthetic bacteria have a variety of heterotrophic functions: nitrogen fixation, denitrification, carbon fixation, sulfide oxidation, etc., are currently mainly used in aquaculture, are closely related to the...

AI Technical Summary

Problems solved by technology

[0004] However, the growth of photosynthetic bacteria requires a suitable external environment and reasonable nutritional conditions in order to reproduce normally and at a high speed and produce high-quality bacterial liquid. However, the current fermentation equipment and methods of photosynthetic bacteria still have certain defects, such as uneven illumination, Photosynthetic bacteria are easy to agglomerate and adhere to the inner wall of the container, etc. Therefore, it is necessary to propose a further solution to the above problems
