Abstract
A self-service food display in which a food tray that is supported by a support structure is cooled by an air stream that passes over and under the tray. The tray has opposed end sections and one or more intermediate sections. The air stream is uniformly distributed over the intermediate sections to substantially maintain the same temperature in the vicinity thereof. The air stream is distributed to the opposed end sections in higher volumes to minimize heat transfer with ambient. The air stream also forms an air curtain that extends above three sides of the food tray. Additionally, the air stream is distributed at an angle to an upper surface of the food tray in a manner that provides higher volumes to the opposed end sections to minimize heat transfer.
