Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a fermentation tank for culturing photosynthetic bacteria. Background Art

[0002] Fermentation tank refers to the device used for microbial fermentation in industry. Its main body is generally a cylindrical cylinder made of stainless steel plate. The fermentation tank adopts a sterile system to avoid and prevent the contamination of microorganisms in the air, greatly extending the shelf life and purity of the product. Fermentation tanks are widely used in dairy products, beverages, bioengineering, pharmaceuticals, fine chemicals and other industries. Photosynthetic culture fermentation tanks are mainly used for fermentation and cultivation of photosynthetic bacteria. Photosynthetic bacteria can photosynthesize in an environment with light and lack of oxygen, using light energy to photosynthesize and assimilate carbon dioxide or other organic matter. Unlike green plants, their photosynthesis does not produce oxygen. In the process of their own assimilation and metabolism, photosynthetic bacteria complete three extremely important chemical processes in the material cycle of nature: hydrogen production, nitrogen fixation, and decomposition of organic matter.

[0003] During the use of existing photosynthetic bacteria fermentation tanks, due to uneven heat from external light sources and insufficient light, internal light sources have become the mainstream in the current market. Since photosynthetic bacteria are phototactic, a large number of bacteria will adhere to the internal light source during the fermentation process, resulting in the lack of light for the remaining photosynthetic bacteria, thereby extending the fermentation cycle and reducing the fermentation efficiency of the fermentation tank. Photosynthetic bacteria will produce gas during fermentation. Existing photosynthetic bacteria fermentation tanks are generally manually vented when in use. If the venting is not timely, the pressure in the fermentation tank may be too high, causing the fermentation tank to explode, affecting the safety of the staff.

[0004] Therefore, we proposed a fermentation tank for culturing photosynthetic bacteria in order to solve the problems raised above. Utility Model Content
