Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, specifically to a microalgae active fermentation device based on multi-mode gas-liquid regulation. Background Technology

[0002] Microalgae are a type of blue-green algae, belonging to the algae family. They are named for their spiral shape. They are a nutrient-rich algae widely used in the production of food, health products, and nutritional supplements. The characteristics of microalgae include high nutritional value: microalgae are rich in protein, with a content as high as 60%-70%, and contain a variety of essential amino acids. In addition, they are also rich in vitamins, minerals, antioxidants, chlorophyll, etc.

[0003] Microalgae are rich in active substances such as proteins, phycocyanin, and polysaccharides. Their nutritional value can be enhanced by co-fermentation with beneficial microorganisms. However, the dissolved oxygen requirements of algae and bacteria vary at different fermentation stages. Existing fermenters usually only use a single gas supply mode, which leads to localized excessive or insufficient dissolved oxygen, thereby affecting metabolic efficiency and the retention of active ingredients.

[0004] Based on this, this invention designs a microalgae active fermentation device based on multi-mode gas-liquid regulation to solve the problem. Utility Model Content

With the cooperation of motor 301 and rotating shaft 302, the rotating shaft 302 can drive the stirring rod 303 and rotating drum 304 to rotate, breaking up the microalgae and forming a vortex inside tank 1. By opening different solenoid valves 403, the oxygen-enriched, micro-oxygen, and nitrogen modes are switched at the beginning, middle, and end of the microalgae fermentation to meet the oxygen supply requirements of microalgae under different fermentation conditions. With the cooperation of connecting plate 501 and air distribution hole 502, the air distribution hole 502 can evenly disperse the gas to ensure uniform oxygen supply to the microalgae. After fermentation is completed, the fermented microalgae can be discharged by activating control valve 105.
