ABSTRACT:
A food holding cabinet having a closed loop air circulating system to control both heat and humidity, the system including a blower having an air inlet at the front-top-center of the interior of the cabinet, the outlet of the blower being connected to an elongated heating tube the discharge end of which directs heated air over a water reservoir containing a plurality of upwardly projecting removable heat transfer plates. The quantity of moisture introduced into the flowing air is controlled by varying the number of heat transfer plates. The heated and humidified air flows downwardly through a duct at the rear of the cabinet, the duct having rows of perforations aligned with the undersides of product containing trays or baskets in the cabinet, the air being drawn through the cabinet for return to the blower inlet. Heat is controlled by a temperature controller having a probe mounted in the inlet to the blower.
