A freeze wheel is provided with an outer skin on which a food or other type product is placed to be frozen. A chamber is formed adjacent the outer skin and a plurality of nozzles project into the chamber for directing a refrigerant onto the inner surface of the skin. The refrigerant flow is controlled to provide a uniform flow pattern along the inner surface to strip away a boundary layer of fluid and maximize heat transfer across the outer skin. The nozzles are arranged in a series of concentric rings with the nozzles in alternate rows lying in common radial planes. An interior portion of the wheel is closed off by one or more doors which may be opened to allow cleaning of the wheel.
