Tray-like device for providing and serving

of food

The invention relates to a tray-like device for preparing and serving food. Such devices are particularly used in air traffic, wherein a plurality of similar trays on Eilander, eta / renartig in compartments of a corresponding frame or service cart ^on; are eordnet. In the known devices of this type, the trays are always kept at one and the same constant temperature, warm or cold, over their entire area. So one and the same tray can only serve food at the same temperature, but not food that is to be consumed at different temperatures »j.

The invention is based on the object of eliminating this disadvantage, that is to say a tray or a tray device

to create this way, by means of which different dishes are stored and served at different temperatures can become; n. A warm main course should be kept at its normal temperature without getting cold,

! while at the same time cold food to be enjoyed at normal room temperature or frozen food _; So dessert or ice cream or the like. can be stored and served.

To solve this problem, the invention consists in that! in one and the same plate several recesses for recording the food are provided thermally insulated from each other, at least one recess with an electrical Heating device is provided.

The tray therefore preferably has a plate made of insulating material, in one of the upper sides of which there are recesses Receipt of cold food is provided, while a larger recess is provided, at the bottom of which an electrical one Heating device is arranged on which a plate for receiving the warm main course is provided. Preferably a device for storing the heat is provided, so that the food is in the manner of a warming plate remains warm after removal of the electrical power supply. A container for oil or the like is preferably used. before-

I seen in which the electrical heating coil is arranged.

The wall, preferably the upper wall, consists of aluminum, in any case of good heat-conducting material.

The plates with the - recesses that are thermally insulated from one another for the food - along with the heating device preferably in a box-shaped housing with a surrounding edge and base. Preferably there is a corresponding one Cover provided, also with a surrounding edge. The recess for the hot dish can be of one be surrounded raised edge, which engages in a corresponding groove on the Üeckelplatte, for the purpose of thermal insulation.

y
The device according to the invention corresponds in its outer contours to known serving trays and, like these, can be used in a known frame or serving trolley.

An exemplary embodiment of the invention is described below with reference to the schematic drawing.

Figure i) shows a vertical cross section.

Figure 2) shows a detail on a larger scale.

Figure 3) shows the device in plan view - with the cover part removed *

Figure 4) shows a large number of tablet devices according to the invention, pushed into the floors of a serving trolley,

According to Figures 1, 2 is a plate 1 made of heat-insulating » Material is provided, in one top of which recesses 2, 3, 4, 5 and a particularly large recess 7 are sunk

309844/0419

are. At least this larger recess 7 must be thermally from the other recesses must be insulated as they are used for keeping warm; a dish is used, while the other recesses are cold ι food to be consumed. The plate 1 is seated

ΐ in a part of the box with a base and a surrounding edge 6.

The top of the recess 7 has a protruding, circumferential one Edge 8 which engages in a corresponding groove 9 which is incorporated in a cover part 10 (Fig. 2). This is the recess 7 for the warm food on its top is also thermally insulated.

The cover part 10 has a flange-like edge 12 to which a Another cylindri divorce 13 is set, the down / down protrudes so that trays stacked on top of each other are supported on the side.

Said larger recess 7 contains a heating resistor J4 taken from an oil tank 15 or other heat storage is. The plug contacts of the heating resistor 14 are denoted by 16, 17, the other contacts (socket) by 18, 19. This heating device 14, 15 is at least on their Top made of thermally conductive material. A plate or plate 20, which is also thermally conductive, is placed or can be placed on it. The hot dish 20 is thus kept warm, while the food entered in the other recesses 2, 3 »4, 5 stay cool.

The serving plates according to the invention are placed in the compartments 22, 23 »24 of a serving trolley 21 in layers. The contact devices 16, 17 on the serving plates arranged one above the other correspond to the penkontacts 28, / St 30 on the serving trolley 21.

Thanks to the invention, the food to be consumed warm is kept warm - while cold on the same platter food to be consumed remains cold; Thanks to the heat accumulator, the wana dishes are also left off after removing the plates electrical power supply kept warm. The cover 10, which is only removed at the last moment, forms a thermal barrier between the cold and the warm food and also protects against the ingress of foreign bodies. You can also use the lid covered plates on top of each other outside of the serving scale stacked while maintaining the temperature.

The cabinet or trolley or the like storage rack to accommodate the Plates on top of each other can also be done with a cooling device be provided while at the same time the hot feed is kept warm by means of a heating device.
