Abstract: A dispensing system for a tank for mixing and freezing ice cream includes a valve selectively pivotable between a first position, a second position and a third position. Pivoting the valve between the first position, the second position and the third position valve meters the flow of the ice cream from the tank. A method of dispensing ice cream includes pivoting a handle to an off position, thereby obstructing with a valve an aperture between the tank and the container. The method also includes pivoting the handle to an on position, thereby aligning the aperture with an aperture of the valve. The method also includes pivoting the handle to an intermediate position between the off position and the on position. Pivoting between the on position and the off position pivots the valve to regulate the flow of the ice cream from the tank to the storage unit.

Abstract: An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator having a cylindrical cooling tank and an auxiliary tank. The auxiliary tank ensures that the cylindrical cooling tank is flooded with liquid refrigerant during normal operation. The flooding of the cylindrical cooling tank provides more efficient and even cooling in an interior cooling chamber. The more efficient cooling allows the ice cream machine to utilize a smaller compressor, thereby reducing the cost and energy consumption of the ice cream machine. The auxiliary tank can be a coil of tubing or a cylindrical container positioned above the cylindrical cooling tank.

Abstract: An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator system with a secondary evaporator. The evaporator system includes a cooling chamber having an ice cream input and an ice cream output. A valve can be placed at the ice cream input to achieve dry freeze operation. The valve can prevent the cooling chamber from being completely filled.
