ABSTRACT:
An agitator able to mix and disperse a variety of fluids of various fluid volumes with different viscosities ranging from low to high, and having excellent, cleanability and improved cooling efficiency is provided. The agitator comprises a rotating shaft3extending vertically inside an agitating vessel2, and a flat paddle blade4mounted on the rotating shaft3. The flat paddle blade has a bottom flat paddle blade portion4aextending outwards from the bottom of the rotating shaft3and a rectangular upper flat paddle blade portion4bextending upward from an upper part of each side end of the bottom flat paddle blade portion4a. The dimensional ratio (b/a) of the blade diameter (b) of the bottom flat paddle blade portion4ato the inner diameter (a) of the agitating vessel2is from 0.6 to 0.9, and the dimensional ratio (d/c) of the height (d) of an upper flat paddle blade portion4bto the height (c) of the bottom flat paddle blade portion4ais from 1 to 4. A passage12is formed inside the rotating shaft3and flat paddle blade4for passing a coolant medium therethrough.
