ABSTRACT:
A mixing apparatus has a chamber, a shaft extending into the chamber, a motor drivingly interconnected to the shaft, a nozzle support affixed to the shaft and extending outwardly therefrom within the chamber, and a nozzle having an interior passageway affixed to the nozzle support such that the nozzle moves in the chamber as the motor drivingly rotates the shaft. The chamber has a multi-phase fluid therein. A flow restrictor is affixed to an inner wall of said chamber so as to extend inwardly therefor. The flow restrictor is a plurality of flat panels arranged in spaced relation around the interior of the chamber and within a liquid phase of the multi-phase fluid.
