A microbial continuous fermentation system and connected fermentation method

Abstract

The invention discloses a microbial continuous fermentation system. The microbial continuous fermentation system includes a first fluid, a fermentation tank and an auxiliary device, wherein the delivery pressure and interval duration of the first fluid can be adjusted, an inlet is formed in the side surface of the fermentation tank, and an outlet is formed in the bottom center of the fermentationtank; the first fluid flows in from the inlet, and flows out from the outlet, the auxiliary device is arranged in the fermentation tank, and the axes of the two coincide; the auxiliary device includesa plurality of auxiliary cylinders with different radii and a plurality of luminous elements and bristles which are fixed to the auxiliary cylinders, the auxiliary cylinders are connected sequentially in a sleeved mode, and first inflow mouths which penetrate the thickness parts of the auxiliary cylinders are formed in the auxiliary cylinders; and at least a part of the auxiliary cylinders can rotate around the axis, and the rotational speeds of every two adjacent auxiliary cylinders are different. The fermentation system is suitable for continuous fermentation of microorganisms, the surfacesof cylinder walls can be cleaned through the bristles on the auxiliary cylinders by means of different rotary speeds of the adjacent auxiliary cylinders, and meanwhile, a liquid in the auxiliary cylinders is stirred, so that aggregation and precipitation of the microorganisms are reduced, and uniform exposure of the microorganisms to light is promoted, and reproduction 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 microbial 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 most widely used photosynthetic bacteria are Rhodospiraceae photosynthetic bacteria. [0003] Photosynthetic bacteria have a variety of heterotrophic functions: nitrogen fixation, denitrification, carbon fixation, sulfide oxidation, etc., are closely related to the cycle of nitrogen, phosphorus, and sulfur in water bodies, and play an important role in the self-purification process of water bodies, as shown in: 1. Purify water quality. Photosynthetic...

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
