A mobile cart for the heating or rethermalization of comestible items at two separate temperatures. A plurality of trays are disposed on a corresponding plurality of shelves within the cart. As each tray is slid onto the shelf, a thermal barrier bifurcates the space above the tray into portions. Each tray is also coupled to a socket disposed within the cart which supplies power to at least two filaments inside the tray, one filament comprising means for obtaining a higher temperature than the remaining filaments. The filaments heat one portion of each tray while the other portion, partitioned by the thermal barrier, is disposed within a portion of the cart which is maintained at or around 0°C by a conventional refrigerator. Comestible items may then be disposed on either portion of the tray according to temperature preference, the tray and cart maintaining and rethermalizing the comestible items at the chosen temperature for an extended period of time. |
