Improvements are provided in machines for processing frozen comestibles of the type in which a frozen comestible is placed in a mixing cup and the mixing cup is moved toward an auger which mixes the frozen comestible into a smooth, soft material. The improvements comprise at least one orifice in a sidewall of the mixing cone and a system for delivering a cleaning and sanitizing solution through the orifice to spray the solution into the interior of the mixing cone. As the mixing cone is moved up and down, the cleaning and sanitizing solution is sprayed into the mixing cone and impinges on the auger to clean and sanitize the auger and the interior of the mixing cone. The system for delivering the cleaning and sanitizing solution preferably comprises a manifold having a hollow interior, with a plurality of orifices in the sidewall of the mixing cone which communicate with the hollow interior of the manifold. The manifold is positioned adjacent to the exterior surface of the sidewall of the mixing cone. A conduit delivers the cleaning and sanitizing solution under pressure into the hollow interior of the manifold, and the cleaning and sanitizing solution is sprayed through the orifices into the mixing cone.

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.

Improvements are provided in machines for processing frozen comestibles of the type in which a frozen comestible is placed in a mixing cup and the mixing cup is moved toward an auger which mixes the frozen comestible into a smooth, soft material. The improvements comprise a chain driven drive for moving the mixing cup toward the auger. Further improvement include spring biased mounting means for mounting the auger of the machine to the drive shaft of the machine. An additional improvement comprises means for circulating cooled air from a freezer located adjacent to the mixing machine through the housing of the mixing machine to cool the mixing cup and the auger.
