Abstract

The present invention comprises a pair of agitator blades which have a plurality of annular members connected to each other and which are provided in parallel in a cylindrical vessel body, the agitator blades being held so that the edges of one of the agitator blades enter the rotational region of the other agitator blade and pass therethrough. Consequently, the invention prevents liquid to be treated from adhering to and rotating together with rotational shafts and the agitator blades and deterioration in product quality due to scaling so as to enable the continuous treatment of a highly viscous material.
