Description

Technical Field

[0001] The utility model relates to the technical field of glucosamine decomposition reaction kettles, in particular to a decomposition reaction kettle for glucosamine production. Background Technique

[0002] Glucosamine is a compound obtained by substituting the hydroxyl group at the 2-position of glucose with an amino group. It is an important functional monosaccharide widely present in organisms. Glucosamine and its derivatives are widely used in medicine, food, cosmetics and other aspects, and have a broad market. Glucosamine is generally mainly obtained by acid hydrolysis or enzymatic hydrolysis of chitin. Using engineered bacteria to ferment glucose is currently a green and safe method for producing glucosamine. However, the fermentation product is N-acetylglucosamine, and an additional enzymatic hydrolysis or acid hydrolysis process is required to convert N-acetylglucosamine into glucosamine.

[0003] However, in actual decomposition fermentation production, the movement direction of the stirring rod or stirring blade in the stirring mechanism of the glucosamine reaction kettle is fixed, resulting in regular diffusion molecules of substances in the solution and unable to be quickly and fully mixed. This will cause insufficient material ratio during the enzymatic hydrolysis or acid hydrolysis of glucosamine, and decompose harmful substances that pollute the environment. Therefore, a decomposition reaction kettle for glucosamine production is proposed. Content of the Utility Model
