AGITATOR HAVING GROOVE FORMED ON THE INSIDE SURFACE OF AGITATED VESSEL

摘要

The present invention relates to an agitator, which has a container on which grooves are formed to increase a mixing degree. The agitator includes: a plurality of protrusions formed on an inner side of a container of the agitator; and a plurality of the grooves formed between the protrusions. Cross sections of the protrusions are independently in the shapes of a semicircle, a semi-ellipse, and a polygon. The protrusions are independently inclined with respect to a perpendicular side of the container. An angle formed by the protrusion and the perpendicular side of the container is 10-70 degrees.
