The outer surface of the blade body defines an inside blade diameter “ID” at the second end and an outside blade diameter “OD” at the first end. The blade body is positioned within and coaxial to the vessel. A scotch yoke, operatively connected to the blade body by a shaft, effects reciprocating longitudinal movement of the blade body through a stroke “S”, with a duration “T” for each stroke. Enhanced mixing efficiencies are achieved when the mixer is operated within a set of operational parameters defined by the equation: 80≦0.36×OD2/ID2×S/T≦550, when OD, ID and S are expressed in inches, and T is expressed in minutes. | ||||||
