  • Patent number: 5472278
    Abstract: A stirring apparatus includes a container with a rotary stirring shaft therein. On the opposite sides of the rotary stirring shaft are mounted an upper vertical flat blade and first inclined flat blades opposite to each other. A first vertical flat blade has a sweptback blade associated therewith, and is mounted to the stirring shaft at a position under the first inclined flat blades, and a second inclined flat blade or blades and a second vertical flat blade having an associated sweptback blade are mounted to the stirring shaft at a position under the upper vertical flat blade. When the stirring shaft rotates, ascending flows of liquid to be processed along the inner wall within a vessel are generated by the upper vertical flat blade and the first and second vertical flat blades that are each associated with a sweptback blade. Descending flows of the liquid to be processed are generated by the inclined flat blades, thereby enhancing the mixing performance.
