Definitions

  • the invention relates to a catering method and a device for its implementation according to the general terms of the independent claims.
  • catering is used in various areas of life: when catering for passengers in means of transport such as airplanes, ships or trains, when catering for the elderly or the elderly, for festive occasions outside of restaurants etc. What is characteristic of catering is that food recipients come from a central kitchen from being supplied with foodstuffs The foodstuffs are delivered in a high-quality form that no longer requires time-consuming preparation, ie the foods are at least partially prepared, pre-cooked or ready to eat. This is usually done in two ways: with warming containers or with microwave ovens.
  • warming containers For a full hot meal, multiple warming containers need to be set up be transported directly to the recipient of the food, e.g. into his home, in order to put the ready-to-eat food from the warming containers directly on the plate.
  • the warming containers are bulky and heavy, which makes the distribution complex. Even in warming containers, the food does not stay hot for an indefinite period of time, so that it has to be distributed in a limited time. The food recipient must consume the food immediately upon receipt, otherwise it will cool down on the plate.
  • Some of the above-mentioned disadvantages of catering processes with warming containers can be avoided by using microwave ovens for the food recipients.
  • the pre-cooked food is delivered in portions in handier, microwave-safe dishes.
  • the food recipient can then determine at which point in time he wants to heat up or finish cook the food in his microwave oven.
  • the disadvantage of this type of catering process is that the quality of the meals often leaves something to be desired.
  • the operation of a microwave oven, especially for the elderly or disabled, can be complicated.
  • the at least partially prepared foods are transported to at least one food recipient and then regenerated by converting electromagnetically induced energy into Joule heat.
  • "regeneration” is understood to mean processes or actions for food preparation which require heat energy, such as thawing, warming up, heating up, boiling, ready cooking, cooking, boiling, braising, roasting, searing, etc.; each of these terms would be too narrow and therefore incorrect for the invention.
  • the food can be transported and regenerated by converting electromagnetically induced energy into Joule heat.
  • the device consists of at least one stationary part and at least one transportable part.
  • the at least one stationary part is located at the at least one food recipient and is an inductive regeneration device with active induction means, typically at least one primary coil.
  • the transportable part contains at least one crockery or at least one container in which at least one crockery can be inserted, as well as reactive induction means.
  • the food is transported in the at least partially prepared state, preferably cooled to, for example, 6 ° C., to the food recipient in the transportable part and regenerated inductively on the stationary part. This regeneration is brought about by the fact that the active and the reactive induction means interact by inducing electromagnetic energy in the reactive induction means from the active induction means and converting them into Joule heat.
  • the at least one transportable part can be designed, for example, as tableware, which receives the food to be transported and regenerated.
  • a harness is typically designed in such a way that it forms the reactive induction means, so that electromagnetic energy can be induced in it by the active induction means in the stationary part and converted into Joule heat. It is preferably closable so that the food can be transported without loss. To facilitate transportation, it can be provided with suspension and / or fastening means. It can be thermally insulating, so that the temperature of the food transported in it stays below the ambient temperature for a long time.
  • the harness can be transported alone or in containers.
  • the at least one transportable part can thus be designed as a container in which at least one tableware can be inserted.
  • a container can hold one dish or several dishes. It enables convenient transportation of several harnesses and protects the harnesses from mechanical and other external influences during transport.
  • the container can be thermally insulated so that the temperature of the transported food remains lower than the ambient temperature for a long time. It can be provided with carrying and / or fastening means to facilitate transportation.
  • a container is preferably designed in such a way that it can be placed on the regeneration device so that the dishes contained therein interact with the regeneration device in order to regenerate the foods in the dishes without the dishes having to be removed from the container.
  • Figure 1 shows a first embodiment of an inventive device for performing the catering process.
  • a stationary part 1 is an inductive regeneration device.
  • a transportable part 2 is a tableware 3, which is intended to hold food (not shown).
  • the stationary part 1, i.e. the inductive regeneration device includes a housing 4 and active induction means, for example at least one primary coil 5.
  • the regeneration device 1 naturally also contains further electrical and electronic parts, which are known per se and need not be explained and illustrated here. These include, for example, means for setting and / or regulating the regeneration output and / or the regeneration time or a sequence of regeneration outputs and / or regeneration times.
  • the transportable part 2 has reactive induction means which cooperate with the active induction means of the stationary part 1 by inducing electromagnetic energy in the reactive induction means from the active induction means and converting it into Joule heat in order to regenerate the food.
  • the reactive induction means are formed by the dishes 3 themselves.
  • the dishes 3 are designed here in such a way that electromagnetic energy in the form of eddy currents can be induced therein by the primary coil 5 in the regeneration device 1 and can be converted into Joule heat; it is typically made of metal.
  • the dishes 3 can be reactive Have induction means in the form of a secondary coil, in which electromagnetic energy can be induced.
  • the dishes 3 In order to be able to transport the food without loss, it is advantageous to make the dishes 3 lockable, that is to say to provide them with a base part 6 and a cover part 7.
  • harnesses 3 that have only one bottom part 6 can also be used in the device according to the invention.
  • the dishes 3 In order to facilitate transport, the dishes 3 can be provided with a carrying and / or fastening means 8, indicated in Fig. 1 with a semicircular handle. Means (not shown here) can also be provided in order to hold the base part 6 and the cover part 7 together.
  • FIG. 2 shows a second embodiment of a device according to the invention for executing the catering process.
  • the stationary part 1 is in turn an inductive regeneration device, in this embodiment with two primary coils 5.1, 5.2.
  • the transportable part 2 is a container 9 in which, for example, two dishes 3.1, 3.2 can be inserted.
  • the container 9 enables a convenient transportation of several harnesses 3.1, 3.2 and protects the harnesses 3.1, 3.2 during transportation from mechanical and other external influences. It can be thermally insulating so that the temperature of the transported food remains lower than the ambient temperature for a long time.
  • the container 9 consists of a lower part 10 and an upper part 11, whereby means (not shown in FIG. 2) can also be provided for fastening the upper part 11 on the lower part 10.
  • the container 9 can be provided with carrying and / or fastening means 8, for example with a handle, in order to facilitate transportation.
  • the dishes can each be provided with a base part 6.1, 6.2 and a cover part 7.1, 7.2 and can be closed. However, they can optionally also have only one bottom part 6.1, 6.2 and be open.
  • the container 9 is preferably designed in such a way that it can be placed on the regeneration device 1, so that the reactive induction means interact with the active induction means 5.1, 5.2 in order to regenerate food (not shown here) in the dishes 3.1, 3.2.
  • the foods in the dishes 3.1, 3.2 can thus be regenerated without the dishes 3.1, 3.2 having to be removed from the container 9.
  • the reactive induction means can be formed by the harnesses 3.1, 3.2 themselves.
  • the reactive induction means for example in the form of secondary coils, can be contained in the container 9.
  • the catering method in the catering method according to the invention, at least partially prepared food is transported to at least one food recipient and regenerated after the transport by converting electromagnetically induced energy into Joule heat.
  • the device according to the invention for carrying out the catering process contains at least one stationary part 1 and at least one transportable part 2 for receiving food.
  • the stationary part 1 has active induction means 5, 5.1, 5.2
  • the transportable part 2 has reactive induction means 3, 3.1, 3.2, so that the reactive induction means 3, 3.1, 3.2 can be influenced by the active induction means 5, 5.1, 5.2 and the foods can be regenerated by converting electromagnetic energy induced in the reactive induction means 3, 3.1, 3.2 into Joule heat.
