ABSTRACT:
An ice cream product mixer of the type having a housing with an open forward side to receive fragile ice cream product serving cups, a mixing head rotating about a vertical axis and having blades each of which generally incline with respect to the axis. Each blade has a lower end section having an undersurface with a lowermost area which is generally disposed substantially closer to a horizontal plane than is the inclination of the undersurface of parts of each blade which are closer to the axis than the lowermost area, so as to cooperate with low speeds for reducing the danger of rupturing the bottom of a fragile cardboard cup and of ice cream spillage therethrough. With the speed low, the use of high driving power and high blade pitch makes possible the rapid mixing of hard ingredients into stiff ice cream in the cups, the outer surfaces of the blades being blunt to reduce danger of puncturing the sides of the fragile cups.
