Abstract
A non-carbonated beverage dispenser having an in-bowl whipper assembly which includes a housing disposed in the bowl and immersed in the beverage, a magnetically driven impeller in the housing, and a discharge passage from the housing connected to the spigot of the dispenser to discharge the whipped beverage from the bowl. The whipper is rotated at 4000 rpm or above, and the height of the impeller blades is made very small (in the order of 1/32 to 1/16 inch) to produce very fine and uniform bubbles in the beverage without uncoupling the magnetic drive.
