Abstract:
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.
