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. The food carts can be initially connected to mating plenum chambers in the food preparation area, then removed and sent to designated areas of the hospital, for instance, where they are positioned into plenum chambers having a control unit at which area a computer control unit takes over and initiates the cooking of those foods to be served hot.
