A flavor mixing and dispensing device for a frozen confection machine including an upright valve cylinder having a discharge outlet at its lower end and a frozen confection inlet port and a plurality of flavoring inlet ports spaced above its lower end. A rotary mixer is provided in the lower portion of the cylinder and a valve piston is slidable in the valve cylinder. The valve piston is formed with a downwardly opening cavity means for receiving the rotary mixer, and the rotary mixer and valve piston are constructed and arranged so that the mixer telescopes into the cavity means in the valve piston when the piston is moved to its lower position, and the mixer and valve piston substantially fill the mixing chamber in the lower portion of the valve cylinder to displace substantially all material from the valve cylinder at the end of a dispensing operation.

Flavor mixing and dispensing device for frozen confection machines

A method and apparatus for preparing and dispensing a semi-frozen food product containing liquid and gaseous ingredients including a refrigerated freezing chamber and volumetric type gas and liquid pumps operable when driven to pump gas and liquid in preselected proportions and under pressure to the freezing chamber. The gas and liquid pumps are motor driven under the control of a pressure responsive control which starts the pumps when the pressure in the freezing chamber falls below a predetermined super-atmospheric pressure range and stops the pumps when it rises above that predetermined super-atmospheric pressure range. The gas and liquid are supplied to the respective pumps under a pressure that is above atmospheric pressure but below the predetermined super-atmospheric pressure range to be maintained in the freezing chamber, and hold-back valves are provided between the pumps and the freezing chamber to inhibit flow of liquid and gaseous ingredients to the freezing chamber until the pressure at the outlets of the pumps exceeds the pressure at the inlets of the pumps.
