ABSTRACT:
A stirring reactor for a viscous material. The reactor comprises a stirring vessel; a revolvable shaft provided in the vessel; a surface layer stirring vane provided on the revolvable shaft in the vicinity of interface of the gas and the liquid to be stirred; a stirring vane having at least a pair of radially directed multiple portion blades which extend radially towards the inner wall, a first of which blade portions is fastened on the revolving shaft below the upper layer stirring vane and the other of which blade portions extends outwardly radially from said first portion to terminate close to the inner wall of the vessel; and baffle plates provided on the inner side wall at positions substantially parallel to the surface layer stirring vane, and at a height between the heights of any stirring vanes having multiple blades.
