Abstract
A mixing device which has a pressurizable chamber for aerating and mixing pumpable products is characterized in that the chamber has its mixing rotor shaft oriented vertically during operation of the mixing device in order to improve efficiency of mixing, reduce vibrations, and to reduce maintenance costs associated with prior art mixing apparatus.
Claims6
A mixing device which aerates and mixes pumpable semi-liquid products comprising:
- a frame;
- a cylindrically-shaped mixing chamber means, having a circumference wall surface with no inlets or outlets, a bottom surface having an inlet, and atop surface having an outlet, said chamber means capable of being pressurized above atmospheric pressure so that products which are input to said chamber means through said inlet at a pressure which exceeds atmospheric pressure exit said chamber means through said outlet, said chamber means supported by said frame so that the axis of the cylinder shape is positioned substantially vertically when said mixing device is in operation, said mixing chamber means having fixed pins attached to an inner surface of said circumference wall of said mixing chamber means so as to extend radially toward the center axis of said chamber means;
- a rotor axially arranged in said mixing chamber means and provided with radial pins which move between said fixed pins when said rotor is rotated, thereby, mixing said products introduced into the mixing chamber.
