Supergravity reactor for intensifying modification of polysaccharide high polymer

The invention discloses a supergravity reactor for intensifying the modification of a polysaccharide high polymer. An outer cylinder body is in a horizontal type structure, the outer cylinder body is internally provided with a reaction inner cylinder, a speed reducer I is connected with a stirring shaft through a coupler, the stirring shaft penetrates through a through hole positioned on an end cover of the outer cylinder body to be inserted into the reaction inner cylinder, and the stirring shaft is fixed on two ends of the outer cylinder body through bearing seats positioned on two ends of the stirring shaft; the outer side of the reaction inner cylinder is provided with a jacket, a main inlet and outlet is arranged on the outer cylinder body, the main inlet and outlet is communicated with the reaction inner cylinder, the stirring shaft is provided with an inner spiral band and an outer spiral band, and the inner spiral band and the outer spiral band are reversely arranged along an axial direction; and the radius of the inner spiral band is smaller than the radius of the outer spiral band. According to the supergravity reactor, the inner spiral band and the outer spiral band move at high speed back and forth to generate strong centrifugal force and shearing force so as to enhance mass transfer and micromixing effect, so that the reaction is intensified, and the reaction time is effectively shortened; in addition, the outer spiral band is capable of scraping to remove a wall-adhering material in time, so that the product quality is enhanced.
