Mobile kitchen unit for operational catering and vehicle unit with a

such kitchen unit

The innovation relates to a mobile kitchen unit according to the generic term of claim 1 and to a vehicle unit according to the generic term of claim 24.

In the sense of the new definition, "operational catering" is understood to mean the provision of food for a larger number of people who are on mobile duty, i.e., for example, the provision of food for police, security and/or auxiliary personnel on mobile duty at a site of operation. In the sense of the new definition, a mobile kitchen unit is understood to mean a mobile kitchen that at least enables the preparation and distribution of operational catering (cook + chili) prepared or pre-cooked in a spatially distant stationary kitchen at the site of operation.

The aim of the innovation is to demonstrate a kitchen unit and a vehicle unit that can be used to provide mobile catering in an optimal manner and that also takes all hygienic requirements into account. To solve this problem, a mobile kitchen unit in accordance with claim 1 and a vehicle unit in accordance with claim 24 are designed.

The new vehicle unit for operational catering consists of the motor vehicle, which is preferably a conventional truck designed as a refrigerated vehicle with a closed body, and the trailer, which with its body forms the completely self-sufficient kitchen unit.

During an operation, the trailer is moved to the site with the motor vehicle, parked there and leveled permanently using a leveling device, for example using spindle winches. The motor vehicle is then used to deliver the prepared and cooled food or meals that are to be

have a shelf life of around three days when refrigerated and are used to return empty containers, in particular the shelf trolleys used to deliver food to the operational staff, crockery, etc. to a stationary, remote kitchen.

Further developments of the innovation are the subject of the subclaims. The innovation is explained in more detail below using the figures for an exemplary embodiment. They show:

Fig. 1 and 2 a truck or motor vehicle designed as a refrigerated vehicle in

side view, top view and section; Fig. 3 and 4 in side view, longitudinal section and plan view of a mobile

Kitchen designed trailer according to the innovation; Fig. 5 a representation of the ventilation and exhaust ceiling of the trailer; Fig. 6 a representation of the lower frame of the trailer to explain the

The two-axle truck 1 in the embodiment shown is designed as a refrigerated vehicle and has a closed body 5 on a vehicle frame 3 behind the driver's cab 4, the interior of which in the embodiment shown is divided into three chambers 6 extending over the entire longitudinal direction of the body 5, each of which is thermally insulated from one another and from the outside. The chambers 6, which are each accessible via their own doors or flaps 7 on the rear of the truck 1, namely via a lifting platform 8 there common to all chambers 6, can be individually cooled, namely via their own evaporator 9. To increase safety, two evaporators 9 of two independent cooling units are provided for each chamber 6. In total, six evaporators are provided, which can be controlled individually, and two independent cooling units, each of which interacts with three evaporators, of which one cooling unit is provided on the front of the body 5 above the driver's cab and one cooling unit is provided as an underfloor unit under the frame or body.

The chambers 6 are dimensioned such that each chamber 6 can accommodate a plurality of shelf trolleys 10 which are connected to one another in the longitudinal direction of the vehicle in this chamber and which are designed with several levels for receiving Gastronorm containers loaded with food.

By dividing the structure 5 into several chambers 6, it is possible to use this chamber differently during each journey, for example one chamber 6 or two chambers 6 for transporting fresh food and two chambers 6 or one chamber 6 for returning dirty shelf trolleys 10, dirty dishes, etc. from the place of use to a stationary commercial kitchen.

With the cooling, the individual chambers can be individually controlled in terms of temperature, for example for the transport of fresh food to a temperature between 0 and 3°C, while for the return transport of shelf trolleys

10, dirty dishes, etc. the cooling of the chamber 6 used for this purpose is switched off.

In addition, it is possible, for example, to transport the clean food in two chambers 6 at a temperature of 0 - 3°C and, for example, to transport other packaged food or drinks in the unclean area at a temperature of approx. 8 - 10 ⁰ C in one chamber 6.

By separating the individual chambers, the separation between clean and unclean, which is essential for hygiene, is guaranteed despite the different uses of these chambers.

The trailer 2, which is also two-axle and can be coupled to the truck 1 by means of a trailer drawbar (not shown), has a structure 12 on its trailer frame 11 in which a completely self-sufficient preparation and reheating kitchen is accommodated, again in such a way that a consistent separation between clean and unclean areas is maintained.

In a separate chamber 13 of the body 12, which is located at the front of the trailer 2, a diesel generator 14 is housed, which essentially consists of a diesel engine and a three-phase generator driven by it with an output of, for example, 115 KVA, for operating the electrical devices, in particular the cooking devices, and the lighting with the usual mains voltage of 230 V. Below the diesel generator 14, in the chamber 13, there is also a tank 15 for the fuel for operating the diesel engine. Above the generator 14, in the chamber 13, there is a cooler 16, which is cooled with outside air via a fan (not shown).

An air inlet 17 is provided for this cooling air on one of the long sides of the trailer or the body 12. In the embodiment shown, this air inlet 17 is located on the left side of the trailer in the forward direction of travel, i.e. at the

Representation of Figure 4 below. A corresponding air outlet 18 is provided on the opposite long side of the body. The chamber 13, which is also soundproofed from the rest of the interior of the body 12 and from the outside, is only accessible from the outside of the trailer via corresponding flaps or doors.

Adjoining the chamber 13, a kitchen area is formed in the interior of the structure 12. On the wall that separates the chamber 13 from the kitchen area 19, a sink unit 20 with a tap for cold and hot water and a shower is provided. This sink unit 20 extends from the lower outer wall in Figure 4, on which the air inlet 17 is also provided, in the direction of the opposite outer wall and ends at the boundary wall 21' of a chamber 21 in which a hot water preparation system in the form of a continuous flow heater is housed, which is operated electrically, for example, and/or via the waste heat of the diesel engine of the unit 14. The chamber 21 is also closed off from the kitchen area 19 and is only accessible from the outside of the trailer 2.

The sink unit 20 is connected along the lower long side of the trailer in Figure 4 by a hand wash basin 23 with a touch-free faucet and sink, and then by a work table 24 with various drawers and wall cabinets 25 mounted above the work table. This work table and wall cabinet combination is followed by a storage space 26 in which several conveyor or shelf trolleys 10 can be parked.

Along the opposite long side of the trailer, following the chamber 21 or the partition wall 21', two pressure cookers 27 and 28 are provided, and following these, an electrically operated stove 28 with a ceramic hob or Ceran hob. The sink 20, the hand wash basin 23 or the base cabinet containing this hand wash basin, the base cabinet 24 forming the worktop, the pressure cookers 27 and the stove 28 are made of hygienic materials.

reasons, arranged flush on a closed base 29, at a level slightly above the level of the rest of the floor of the kitchen area 19. This base 29, in which supply and disposal lines, i.e. in particular the electrical lines for the electrically operated devices, the lines for the supply of hot and cold water and soft water as well as the waste water lines of the sink 20 and the hand wash basin 21 are laid, enables reliable and hygienic cleaning of the kitchen area 19 in the area of the floor 30, which is designed to be non-slip. Opposite the storage space 26 and following the stove 28, two hot air steamers 31 are provided, into each of which a shelf trolley 10 can be pushed in order to heat the food held by this trolley.

Adjoining the kitchen area 19 at the rear of the trailer is a room 32 which is separated from the kitchen area 19 by a door, for example an automatically opening door 33, and in which a circulating air refrigerator 34 is provided on the upper long side of the trailer in Figure 4 and a built-in cupboard 35 is provided immediately adjacent to the rear of the trailer. On the opposite side, the anteroom 32 is separated by a wall from a chamber 36 which is used to hold waste containers or Gastronorm containers for food waste and which is only accessible from the outside of the structure for hygienic reasons.

A lifting platform 37 is provided on the rear of the trailer 2, which forms a horizontal platform when unfolded, which can be reached via a fold-out staircase 38 and through which the anteroom 32 can be reached through a door 39. The lifting platform is provided with a roll-off protection 37', which prevents shelf trolleys 10 from rolling over the rear edge of the lifting platform or the horizontal platform. A weather protection tarpaulin 37" is also provided for the lifting platform 37. The staircase 38 is provided with plug-in railings and can be folded onto the inside of the lifting platform for transport.

In the ceiling of the anteroom 32 there are two electrically operated insect killers 40. A ventilation ceiling is provided for the ventilation of the kitchen area 19 (Fig. 5), which has a supply air fan 41 with a silencer and an electrical device for heating the air. The air outlet 42 of this ventilation ceiling, equipped with appropriate filters, runs along the lower long side of the structure 12 in Fig. 4 in the embodiment shown. The air inlet 43 of the ventilation ceiling is also located on this long side. On the other long side, in the ceiling of the kitchen area 19 above the pressure cooker 27, the stove 28 and the two hot air steamers 31, the exhaust air area 44 of the ventilation ceiling is provided, which conveys the exhaust air via an exhaust air fan 45 with silencer to an exhaust air outlet 46, which is provided on the upper long side of the structure in Figure 4, namely where the outlet 18 of the engine cooling is also provided. The air inlet 43 and the air outlet 46 can be opened and closed by motor, for example using an electrically operated flap.

Below the frame 11 there are several tanks which are thermally insulated and thus also protected against frost, namely a dirty water tank 47 for holding dirty water, a fresh water tank 48 for holding fresh water and a soft water tank 49, i.e. a tank for holding decalcified or essentially decalcified water for operating the steam generators of the hot air steamers 31.

For optimal control or distribution of the available electrical energy to the individual devices, the electrical supply of the trailer 2, generally designated 50 in Figure 7, has a measuring circuit 51 which measures the current electrical consumption of all devices or consumers of the trailer and controls a device 52 for power optimization, which controls the individual consumers or devices, designated 54 in the figure, via its connection module 53 or via its outputs according to a predetermined program in such a way that optimal use of the power provided by the unit 14

is possible. The electrical supply also has a changeover switch 55, via which the electrical supply 50 from the unit 14 can be switched to an external supply, provided that such is available at the site of use.

In the figure, 56 designates a device that serves to document the temperature over time and is used to monitor and record temperature target and actual values as well as the cooking time. For this purpose, the device 56 is connected via temperature modules 57 to temperature sensors 58 on the cooking kettles 27 and the combi steamers 31. The temperature measurement data supplied by the temperature sensors 58 or the modules 57 are stored in the device 56 together with the respective cooking or boiling time for documentation purposes, for example over a period of 365 days.

The electrical supply 50 with the measuring device 51, with the device for performance optimization and with the connection module 53, as well as the device 56, are accommodated in the chamber 21, which also serves as an installation room.

In order to secure the rack trolleys or trolleys in the respective chamber 6 of the motor vehicle 1, at least one securing or separating rod 59 is provided for each chamber 6, which can be anchored in the walls 6' in the horizontal direction transverse to the longitudinal extent of the respective chamber 6, as is indicated in a very simplified manner in Figure 8 for one end of the separating rod 59. For this purpose, the separating rod 59 is provided at both ends with a pin 60 which can be inserted into holes 61 of a row of holes 62 and anchored there. On the mutually facing sides of the walls 6' delimiting the respective chamber 6, a row of holes 62 is provided in the horizontal direction. Each row of holes 62 on a wall 6', formed for example by a metal profile embedded in the wall 6', is located with its holes 61 directly opposite the corresponding holes 61 of the row of holes provided on the other wall 6' in the horizontal direction and transversely to the chamber 6.

a20353.doc : :: .'&igr;::

In order to enable the pins 60 to snap into the holes 61, the pin 60 provided at at least one end of the separating rod 59 is spring-loaded in the axial direction by means of a compression spring 61 and can be actuated to release the separating rod 59 via a handle or button 60' projecting radially away from the separating rod 59.

The shelf trolleys 10 arranged in a chamber 6 are connected to one another in this chamber, starting from the front end of the structure 5, with a deflector 65 provided on the underside above the rollers or wheels 64. At the front end of the structure 5 and on the walls 6', ram protection 66 is provided, which forms a system for the deflectors 65 of the shelf trolleys 10. The last shelf trolley 10, which is furthest away from the front end of the structure 5, is fixed by the separating rod 59, so that all the shelf trolleys 10 are secured against unwanted rolling back and forth.

As indicated in Figure 2 with 6", the inner walls or partition walls 6' between the outer chambers 6 and the inner chamber 6 at the rear end of the structure 5 are designed to be pivotable, so that the entry and exit of the control carriages 10 into the two outer chambers 6 is facilitated when the wall sections 6" are pivoted inwards.

In Figure 4, 67 also designates a floor channel covered by a grid, which in the embodiment shown extends in front of the pressure cooker and has drains with odor traps.

By means of a leveling device, the frame 11 and thus also the structure 12 of the trailer 2 parked on the ground can be aligned exactly, so that all horizontal and vertical axes and planes of the trailer are actually oriented horizontally or vertically. In the simplest case, the leveling device is formed by manually operated spindle winches, one of which is indicated at 68 in Figure 4.

The innovation has been described above using an exemplary embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the innovation.
