ABSTRACT:
Efficient mixing is promoted in a turbulent stirring unit by providing an agitator with flexible finger-like appendages and by varying the rate of rotation of a rotating magnetic field such that the fingers execute an undulatory motion, disrupting laminar flow and tending to collapse the liquid vortex. Motor control for controlling the fluctuation of the rotating magnetic field may provided by simple and economical electronic or electromechanical means. The control unit may be separately configured to control a number of other pieces of equipment, either in common or independently. The controller also may be integrated into stirrers, vortexers or shaker tables or externally provided to control existing units.
