Chitosan micromolecular degradation turbulent flow reaction tank

Abstract

The invention discloses a chitosan micromolecular degradation turbulent flow reaction tank. The chitosan micromolecular degradation turbulent flow tank comprises a tank body; a vertically arranged stirring shaft is rotationally mounted on the tank body; a stirring impeller is arranged on the stirring shaft; a plurality of radial turbulent flow plates are arranged on the inner wall of the tank bodyin the circumferential direction; a plurality of turbulent flow through holes are formed in the radial turbulent flow plates; rotational flows generates turbulent flows through the turbulent flow plates, so that catalytic degradation of the chitosan is promoted; the turbulent flow plate at the bottom of the tank enables the bottom of the tank to generate turbulent flows, so that the chitosan settled at the bottom of the tank is lifted and catalytic degradation of the chitosan is further improved; and a turbulent flow riser is additionally provided, so that rotational flows in the vertical direction are increased while rotational flows are generated in the horizontal direction, catalytic degradation of the chitosan is promoted and the degradation rate of the chitosan is increased.

Description

technical field [0001] The invention relates to the technical field of reaction tanks, in particular to a chitosan small molecule degradation turbulence reaction tank. Background technique [0002] Chitosan, also known as chitosan, chitosamine, hexanoyl chitin, chitosan, is the product of deacetylation of chitin after concentrated alkali treatment, and is the second largest natural product with annual output after cellulose. Polymer is also the only natural alkaline polysaccharide found so far. However, because of its ordered macromolecular structure, chitosan can only be dissolved in a few dilute acids, but not in water and general organic solvents, which limits its application to a large extent. The small molecular chitosan obtained by degradation, especially the small molecular chitosan with a relative molecular mass below 10000, is not only soluble in water, but also has unique physiological activities and physicochemical properties, such as controlling cholesterol, inh...

AI Technical Summary

Problems solved by technology

Most of the existing stirring reaction tanks adopt the method that the stirring blade on the stirring shaft directly drives the solution to swirl. The chitosan part rotates synchronously with the solution, and the mixing with the solution is not sufficient, and the other part will sink to the bottom of the tank, and cannot be fully mixed. Degradation, so the degradation rate of chitosan is not high
