Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chitosan oligosaccharide enzymolysis device, specifically to a chitosan oligosaccharide enzymolysis device for chitosan oligosaccharide preparation. BACKGROUND

[0002] The chitosan oligosaccharide enzymolysis device is a device specially used for chitosan oligosaccharide enzymolysis process. Chitosan oligosaccharide, also known as chitosan oligosaccharide or oligochitosan, is a low molecular weight product with good water solubility, large functional effect and high biological activity, which is obtained by special biological enzyme technology. The chitosan oligosaccharide enzymolysis device realizes uniform mixing and efficient enzymolysis of chitosan oligosaccharide raw materials through stirring and heating in multiple processes, avoiding accumulation of raw materials during material falling, and improving the rate of enzymolysis reaction.

[0003] The common chitosan oligosaccharide enzymolysis device can only stir in the enzyme hydrolysis tank during use, and cannot clean the inside of the tank. During the enzymolysis process, some residues or by-products may adhere to the inner wall of the tank. These residues will gradually accumulate, which may reduce the enzymolysis efficiency and even affect the quality of the final product, causing certain adverse effects in the use process. Therefore, we propose a chitosan oligosaccharide enzymolysis device for chitosan oligosaccharide preparation. UTILITY MODEL CONTENT

[0004] The technical problem solved by the utility model is that the chitosan oligosaccharide enzymolysis device provided by the utility model has the advantages of cleaning and ensuring product quality. The stirring and wall scraping telescopic mechanism is provided. The second control motor drives the first bevel gear to drive the second bevel gear to rotate. When the second bevel gear rotates, it can drive the connecting rotating rod and the control telescopic rod to rotate together. The telescopic movable rod is sleeved on the outer wall of the control telescopic rod through the inner connecting thread groove. When the control telescopic rod rotates, it can drive the telescopic movable rod to extend and retract on the outer wall of the control telescopic rod. The limiting block plays a limiting role in the control telescopic rod to prevent slipping. When stirring is needed, the telescopic movable rod can be retracted. The rotating control rod drives the control connecting disc to drive the outer telescopic frame and the telescopic movable rod to rotate for stirring operation in the enzyme hydrolysis tank. The telescopic movable rod can drive the scraper strip to clean the inner wall of the enzyme hydrolysis tank, preventing the accumulation of residues and impurities and avoiding cross contamination, thereby ensuring the quality stability of each batch of products. Regular cleaning can prevent the accumulation and hardening of residues, reduce corrosion and wear of the equipment, thereby prolonging the service life of the equipment and effectively solving the problems in the background technology.
