Abstract: A frozen dessert mixing machine of the type including an auger and mixing cone which has an open top, wherein the mixing cone moves toward the auger and the auger mixes a frozen desert from material contained in the mixing cone. The mixing machine further comprises means for effectively closing the open top of the mixing cone during the mixing of the desert material so that a liquid material can be included in the mixing cone to be mixed with a frozen material in the mixing cone without the liquid material or resulting mixture being ejected from or otherwise escaping from the mixing cone. A valve mechanism is associated with an opening in the bottom of the mixing cone so that the resulting mixture in the mixing cone can be dispensed from the bottom of the mixing cone when the valve mechanism is opened.
