ABSTRACT:
An agitator for providing uniform and rapid material mixing is provided comprising a first sweep blade mechanically coupled to a second sweep blade. The first sweep blade extends from a first sweep blade origin to a first sweep blade terminus along a first substantially helical path defined about a first helical axis. The second sweep blade extends from a second sweep blade origin to a second sweep blade terminus along a second substantially helical path defined about a second helical axis. The respective orientations of the first sweep blade along the first substantially helical path and the second sweep blade along the second substantially helical path define a first flow direction extending from the first sweep blade origin to the second sweep blade terminus. An agitator assembly is provided comprising a first agitator, a second agitator, a mixing bowl enclosing the first and second agitators, and a driving assembly coupled to the first and second agitators. The second agitator is oriented substantially parallel to the first agitator. The first agitator defines a first flow direction extending from the first sweep blade origin to the second sweep blade terminus. The second agitator defines a return flow direction extending from the third sweep blade origin to the fourth sweep blade terminus. The return flow direction is opposite the first flow direction.
