Abstract: A frozen yoghurt or ice cream dispensing system is presented. This system costs a small fraction that of the state of the art dispensing system, yet it is more versatile and puts out a better product, than the state of the art systems. A pre-formed "hard" frozen single serving of the base confection and fresh flavoring additives are loaded into an extrusion cup. At the actuation of a hand crank, or a power drive switch, a rotating cutter/sweeper on a retractable shaft, penetrates the confection charge and chops, softens, and mixes it. After this cutter engages the bottom of said cup, a piston traverses the loading cup bore, and the charge is extruded through a multi-aperture orifice, at the bottom of the extrusion cup. Shearing and additional mixing occurs, during the interaction of the rotating cutter and the multi-aperture orifice. An automatic rinse cycle is also built into the device, to eliminate flavor mixing between various batches of confections, and to save labor.
