Horizontal continuous fermentation system and continuous fermentation method

Abstract

The invention discloses a horizontal continuous fermentation system. The horizontal continuous fermentation system comprises a first fluid, a fermentation container and auxiliary appliances; the conveying pressure and interval time of the first fluid can be adjusted; the auxiliary appliances are suspended in the fermentation container; a plurality of auxiliary appliances are arranged in parallel in the height direction of the fermentation container; each auxiliary appliance comprises an auxiliary plate, luminous pieces fixed with the auxiliary plate, and brush hairs; the auxiliary plates are made of a transparent material; the brush hairs are arranged on the surface of each auxiliary plate; and the length of the brush hairs is greater than the distance between every two adjacent auxiliaryappliance. The fermentation system is suitable for continuous fermentation of microorganisms, self-shaking of the auxiliary appliances in the fermentation container is realized through a first fluid which is continuously input at intervals, then stirring of liquid in the fermentation container is realized, and aggregation and precipitation of microorganisms are reduced, so that the microorganismsto be uniformly exposed to light, and propagation of the microorganisms is promoted.

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 connected 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. 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 nitrogen, phosphorus, and sulfur cycles in water bodies, and play an important role in the self-purification process of water bodi...

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
