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.

1. A self-service food display comprising:a support structure having a base, a back and a top; a food tray having a front end, a back end and opposed side ends and supported by said support structure so as to be exposed to ambient on said front and said opposed side ends; a ductwork extending beneath said food tray, up said back and across said top and having air curtain ports arranged therein for the formation of a front air curtain and at least one side air curtain; means for circulating a cool air stream through said ductwork and to form said front air curtain and said at least one side air curtain; and an array of ports disposed at a location in said ductwork to provide a uniform distribution of air flow in a path that is incident to an upper surface of said food tray at an acute angle and to provide higher volumes of said air flow to said opposed ends to minimize heat transfer to ambient.
