Abstract
The present invention relates to an apparatus and method for mixing fluids in a manner that ranges from maintaining the integrity of fragile molecular and biological materials in the mixing vessel to homogenizing heavy aggregate material by supplying large amounts of energy. The variety in mixing manner is accomplished using an electronic controller to generate signals to a motor driver in order to control the frequency and the amplitude of the motor, which drives an agitator assembly. The motor may be a stepper motor, a linear motor or a DC continuous motor. By placing a sensor in the mixing vessel to provide feedback control to the mixing motor, the characteristics of agitation in the fluid can be adjusted to optimize the degree of mixing and produce the highest quality mixant, with consistent results.
