Definitions

  • the invention relates to a method and a device for the ready-to-transport preparation of meals in individual portions according to claims 1 and 7 and a heat shielding part used in accordance with claim 19.
  • the invention is therefore based on the object of providing a method for the ready-to-transport preparation of meals in individual portioning or an apparatus for carrying out the method and a heat shielding part used thereby, with which it is possible to economically prepare meals in to bring the temperature to the consumer in good condition even after prolonged transport.
  • a targeted thermal treatment of selected compartments of the container is preferably carried out after the container has been filled with the food, ie regularly shortly before the container is closed.
  • an additional amount of heat is supplied with the food and the interior concerned, which only has to be large enough to cover the amount of heat otherwise given off to the container parts and to the environment.
  • This additional amount of heat introduced is effectively captured by the subsequent closing of the container in the selected areas. As a result, it is possible to transport adjacent foodstuffs with very different temperatures even over longer distances and to keep their temperature at an optimal value.
  • a heat shielding part is provided so that the ambient heat does not ultimately heat up all areas of the base part filled with food, into which the base part part is inserted.
  • this heat shielding part contains selected sections which allow the heat to be supplied to the selected sections of the base part. With this measure it is achieved that the heat flow can be controlled in an advantageous manner and can be directed towards those departments of the base part in which the hot dishes are located. Furthermore, it is achieved with the heat shielding part that neighboring departments, which may have been filled with cool or chilled food, are separated from the general ambient heat. This mutual shielding of the container sections to be kept at different temperature levels is improved by the heat shielding part.
  • the heat loss of the heat supplied via the heat shielding part which is only slight according to the invention, can be reduced if, according to claim 2, the areas of the cover part are specifically heated before closing. In this way, the lid part of the food does not remove any significant heat.
  • the heat shielding part is cooled via a cooling device between the heat cycles. This means that the controlled supply of heat can be controlled more easily.
  • the heat balance between the warm food and the preheated selected section of the base part is less than would be the case if warm dishes were filled in a cold base part. So that food to be transported cool is not heated, a cooling unit can be inserted in the designated sections of the base section before filling the cool food in the designated or unselected sections of the base section. In this way it is further guaranteed that on the one hand the required heat supply for the food to be kept warm is low, but on the other hand that cool food is not heated by the preheated sections of the base part.
  • a particularly simple device for carrying out the method is the subject of claim 7.
  • a device which has a receiving device for receiving a bottom part of a container, the bottom part with filling, ie by individual portioning in the different departments , Filled food for heating selected sections of the base part is held by a heating unit.
  • the thermal energy is brought as loss-free as possible to those locations that are important for the targeted thermal treatment of the container sections of the base part.
  • the receiving device of the device according to the invention is formed by a heat shielding part and a heat shielding part holder, the advantage results that different conditions can be dealt with in a simple manner.
  • the heat shielding part contains selected sections, the heat supply or the heat conduction can be adjusted in a targeted manner.
  • the selected sections according to claim 10 are formed by a heat-permeable layer, whereas according to claim 11, the selected sections can also be formed only as openings. The latter measure ensures that the radiant heat can also be directed directly onto the base part.
  • the receiving device is coupled to a transport device, then the selected sections or the hot dishes can be heated in cycles in a simple manner, the receiving devices or heat-shielding parts also heating up each time until the next most of the heating process cool down independently. If the heat shielding part itself is kept cool, the heat shielding part would first have to be heated in order to heat the entire base part.
  • the cool heat shielding part ensures that the heat quantity is preferably supplied through the selected sections of the heat shielding part.
  • the transport device can be rotated in a simple manner and, according to claim 14, can be designed as a revolving conveyor belt, in which the revolving heat shielding parts can cool off independently in the interim period between the heating processes. If the number of cycles of heating increases, then according to claim 15 a cooling device can be provided which is cooled before each heating of the selected departments or the dishes, so that the heat transfer only through the opening or the heat-permeable layer and does not take place in any other way from the possibly heated-up heat shielding part to the bottom part.
  • the device is developed according to claim 16, there is an additional focusing of the thermal energy and thus an even lower energy requirement or a higher efficiency of the device. This applies in particular if, according to claim 17, the heating sections of the heating unit come to lie opposite the sections of the base part to be heated.
  • the control of the amount of heat to be transferred from a heating element to a container can be carried out specifically if, according to the invention, a heat shielding part is used which has receiving areas into which separate compartments of the container can be accommodated.
  • the receiving areas in turn are subdivided into selected sections, each of which in turn allows a quantity of heat to be supplied to selected sections of the base part.
  • a channeling of the heat flow is provided, which can thereby be aimed at preselected sections of the container and an inadvertent heating of the cool dishes, which are also filled by individual portioning, cannot take place.
  • FIG. 1 shows an exploded view of a base part filled with food, which is inserted into a heat shielding part provided for this purpose, which is then held via a heating unit required for heating in accordance with an embodiment of the present invention
  • FIG. 2 shows a perspective view of the device according to the invention for the ready-to-transport preparation of dishes
  • FIG. 3 shows a cross-sectional view of the device for the ready-to-transport preparation of dishes according to a further embodiment.
  • a bottom part IB filled with dishes and containing dishes to be kept at different temperatures is inserted into a receiving area 19A, 19B, 19C having heat shielding part 3 inserted, which are then held by a heating unit 5.
  • the bottom part of a transport container shown in FIG. 1 can preferably have the configuration as disclosed in the applicant's earlier patent applications P4325205, P19506394, P4410945 and P19526719.2, the disclosure content of which is hereby expressly included in the disclosure content of the present application.
  • the heating unit 5 is designed in such a way that the heating sections 5A, 5B, 5C each come to lie opposite the areas of the base part IB to be heated.
  • the heating sections 5A, 5B, 5C can moreover have contours which are configured in the same way as the assigned departments of the base part IB.
  • the individual heating sections 5A, 5B, 5C are connected to a control unit 17, which brings the individual heating sections 5A, 5B, 5C separately and optionally with different temperatures (adapted to the respective dishes) to heating. If, for example - as shown in FIG. 1 - the bottom part IB is partly filled with hot dishes and partly with cold dishes (such as salad), the heating sections 5A, 5B are heated according to the invention , so that only the warm dishes experience a further supply of heat.
  • the control function and the heating behavior of the heating unit 5 can thus be varied from time to time.
  • Letters A and B denote the selected sections of the heat shielding part which allow heat to be supplied to the base part.
  • the device shows an embodiment of the device according to the invention for the ready-to-transport preparation of meals in individual portions.
  • the device has receiving devices 9, which are formed from a heat shielding part 3 and a heat shielding part holder 11.
  • the bottom part IB filled with food is inserted into this heat shield part 3 and held by the heating unit 5, which is provided with a control unit 17.
  • the device shown in FIG. 2 and which can be defined by four, preferably five phases (phases I, II, III, IV or V) is designed to be rotatable (see arrow).
  • phase I the base part filled with food is inserted into the heat shielding part 3 and held by the heating unit 5 by the rotary movement. In this position, the selected sections of the bottom part IB are heated (phase II).
  • the heating time can vary depending on the desired heating output and the selected dishes.
  • reheating to, for example, 87 ° C. can take place in a few seconds ( ⁇ 10 seconds).
  • the base part IB is removed from the heat shielding part 3 (phase III) and possibly closed with a cover part IA matched to the base part IB. It is quite conceivable that the container can also be closed during phases II and III.
  • the heat shield part 3 is continued by the rotary movement and possibly shortly before it is equipped with a further base part IB containing food, cooled at V by means of a cooling unit (not shown), so that heat transfer between the possibly also heated heat shielding part 3 and the newly inserted bottom part IB do not take place.
  • the rotating device can also be formed with a circular plate into which a heat-shielding part 3 is preferably each equally spaced in the circumferential direction. This ensures that the ambient air warmed up by the heating unit 5 is also kept away from the base part IB at an elevated temperature.
  • FIG. 3 also shows a device according to a further embodiment, the transport device 13 being designed as a conveyor belt.
  • a heat shielding part 3 was embedded on this conveyor belt at equal intervals.
  • This embodiment of the device also contains phases I to V that are comparable to those in FIG. 2.
  • the method according to the invention or the device according to the invention and the shielding part according to the invention can not only be used to transfer heat specifically to a container, but can also transmit cold in the reverse case.
  • additional cold is specifically introduced into at least those departments of the base part which are filled with cold dishes before being closed, the base part being inserted into a heat shielding part which contains selected sections which provide the cold supply to the selected departments of the base part.
  • a device is provided with a receiving device for receiving a base part, which holds a base part equipped with food for cooling selected portions of the base part via a cooling unit or device.
  • a shielding part is provided, which contains receiving areas which are received in separate compartments of a container, the receiving areas being subdivided into selected sections which allow cold supply to selected departments of the base part.
