ABSTRACT:
A beverage powder mixing drink dispenser has a hopper for containing a supply of powder, a source of water and a controller, all contained within a housing has a mixing assembly, an electrical motor with an annular stator mounted to the housing and an annular rotor mounted to rotate around a motor axis within the annular stator when the stator is energized, a mixing chamber with a hollow body having an interior surface extending between a chamber inlet and a chamber outlet and at least one mixing member extending inwardly from and mounted to the interior surface to rotate with rotation of the hollow body, means for releasably mounting the hollow body of the mixing chamber to the rotor to rotate with the rotor relative to the stator about the motor axis, and means for controlling energizing of the stator, the accumulation of clogging moisture on the powder outlet is reduced by rotating the mixing member at a relatively high mixing speed during mixing to mix the powder with the water in the mixing chamber and rotating the mixing member at another relatively lower vent speed to draw air through the mixing member and away from the powder outlet during times that the mixing member is not being rotated at relatively high mixing speed to mix a drink.
