Abstract: Food is prepared by placing selected food items in pre-determined locations on food trays, placing the trays on shelves of a rack in a food and beverage cabinet with the food and beverage cabinet being inserted in a first environmental control unit which circulates chilled air over the trays and then removing the food and beverage cabinet and placing it at a second environmental control unit which additionally heats selected food items.

Abstract: An apparatus for preparing cooked or heated meals includes a food and beverage cabinet having heater shelves which include spaced heater elements heated by film heater means with silicone rubber comprising the sole means for securing the film heater means to its heater element and with silicone rubber further completely surrounding each heater element and being disposed between its heater element and film heater means to insulate the heater element from and raise it above the top layer of the shelf.

Abstract: The invention relates to a food serving tray for use with apparatus for preparing wholesome meals for patients in hospitals, rest home residents, airline passengers, prisoners and the like. The tray has a plurality of dish size openings extending through the tray. Each dish size opening includes a raised circumferential bead for supporting a dish having a circumferential notch around the lower portion of the dish. The tray has a raised edge along the tray perimeter and tray guiding notches are formed in one side of the raised edge around the tray perimeter for guiding the tray along suitable tracks of a heater shelf rack. The tray can include a series of dish or food supporting indents in the tray surface. Half-size trays are also included in the invention with tray guiding notches in opposing sides of the raised edge around the tray.

Abstract: A portable cart with access doors has serving trays supported on heater shelves which trays support the food items to be served to the patient. Chilled air for the cart is provided by an air chilling device to a plenum chamber which chamber when coupled continuously circulates chilled air from the chilled air device into and through the cart and then back through the plenum chamber to the chilled air device in a continuous closed loop pattern. The circulating air passes through mating vents and inlets of the plenum chamber and the cart which automatically open when the cart is coupled with the plenum chamber. The heating for each food item to be served hot is initiated, time controlled and terminated by a programmed computer which separately controls the operation of the individual heater plates mounted on the heater shelves supporting the trays.

Abstract: A food serving tray and heater shelf arrangement includes a rack having sets of cantilevered supports with a heater element mounted to each pair of supports and with a food serving tray on each heater element straddling its supports.
