Abstract (en)

A mixer apparatus for use with a vessel centered about a longitudinal axis is disclosed. The mixer has a blade body is formed along a central axis. The blade body has a first end, a second end spaced from the first end along the head axis, and passageway extending between the first and second ends. The passageway tapers from the first end to the second end. The outer surface of the blade body defines an inside blade diameter "ID" at the second end and an outside 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 thought 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 x OD 2 /ID 2 x S/T ‰ 550, when OD, ID and S are expressed in inched, and T is expressed in minutes.
