The invention concerns a chamber (1) divided into two zones (11, 12) for preservation at different temperature, separated by a vertical mobile thermal barrier (10), capable of sliding horizontally and enabling said zones (11, 12) to exhibit modifiable dimensions as required. The meal trays (4) comprise, on opposite edges, notches (7) adapted to receive a removable insulating partition (8, 9) separating the meals (13) to be served hot from those to be served cold and whereof the position can be modified to correspond with that of the thermal barrier (10). Vertical sheaths (21) enable, by means of turbines, to circulate warm or cool air, through orifices (22). A valve (23) prevents the air in sheaths (21) from passing through the evaporator (18). Electric resistors (16) with fins are arranged opposite or beneath the meal trays (4). A refrigerating compressor (20, 20'), provided in a lower casing (2) or an upper casing (3), for cool air diffusion and circulation, feed the evaporator (18).

1. A device for the preservation and reheating of tray meals with modular hot and cold regions, which comprises a thermally insulated, stationary or movable, chamber comprising a lower box and an upper box separated by a space able to contain several stacked tray meals and having, passing through these tray meals, two independent circuits, namely a cooling circuit and a reheating or cooling/reheating circuit, wherein the chamber is divided into two regions separated by a vertical movable thermal barrier which can slide horizontally and allows said regions to be at different temperatures and to have dimensions that can be modified according to requirements, the tray meals having, on two opposed edges, notches capable of housing a removable insulating partition separating dishes to be served hot from those to be served cold and a position of said insulating partition may be modified to correspond with that of the thermal barrier. 2. The device as claimed in claim 1, wherein the chamber includes vertical ducts or compression columns making it possible, by means of turbines, to compress hot air or cold air via openings in the regions, this air passing through the tray meals via orifices. 3. The device as claimed in claim 1, wherein cold air is produced by means of a refrigerating compressor placed in the upper box or in the lower box, said compressor supplying at least one evaporator which is located in the upper box and includes a cold accumulator. 4. The device as claimed in claim 1, wherein the reheating circuit includes a valve located in the upper box to prevent, when it is closed, air from compression columns passing via an evaporator, finned electrical resistance elements placed facing the tray meals then making it possible to heat the air, which reheats the dishes, and is then extracted and sucked out by a turbine, returns to the compression column and redescends before being recycled. 5. The device as claimed in claim 1, wherein the thermal barrier, has receptacles for the insulating partitions of the tray meals and resistance elements for reheating one of the regions, comprises a removable assembly that can be removed from the chamber, this assembly being held in place by a locking device locked by a pull cord. 6. The device as claimed in claim 1, wherein the chamber is stationary and comprises compression columns, turbines, a refrigerating compressor, an evaporator or evaporators with a cold accumulator, and resistance elements used for reheating one of the regions or directly under the tray meals, the space between the lower box and the upper box being entirely clear and designed to house a trolley carrying the tray meals. 7. The device as claimed in claim 1, wherein slats make it possible, when one of the tray meals is removed, to close off an orifice or slot made in the thermal barrier for slotting in the tray meals, an articulated movable catch causes this slot to open and allows the tray, with the insulating partitions, to be slotted into position. 8. The device as claimed in claim 1, wherein the tray meals are placed in two stacks and can be inserted into the chamber or removed therefrom via doors placed on two opposed sides of said chamber.
