ABSTRACT:
A food serving system for delivering prepared meals to locations remote from the point of preparation, such as to patients in hospitals and nursing homes, which includes a mobile cart having its own low voltage rechargeable power pack that may be utilized to make the cart self powered. The cart has a tier of racks for carrying removable, generally flat, individual, food serving trays. The trays may be disposable or reusable. Each tray is provided with one or more thermally isolated heat transfer devices which may be energized when the tray is placed on a rack in the cart. The trays are constructed to carry conventionally styled, removable dishes, bowls, cups, etc., that may be either disposable or reusable, and the dishes and bowls containing foods to be maintained at a reduced or elevated temperature are placed on the heat transfer devices. The heat transfer devices are intended to maintain the food in the dishes and bowls at the desired serving temperature for extended periods without affecting the temperature of the foods and beverages in other dishes, bowls and cups on the trays, so that when the cart is moved about the hospital they remain at their desired temperatures and the individual trays may be brought to the patients with the different foods and beverages at their separate selected temperatures.
