Definitions
- the invention relates to a device for maintaining the temperature of refrigerated food with a food container for holding the food and a be charged with a coolant cooling module.
- thermocontainer system which enables a temperature maintenance of the food using carbon dioxide snow.
- a cooling module is installed in a food container into which liquid carbon dioxide can be introduced.
- carbon dioxide snow is produced, which is created by sublimation of carbon dioxide snow cold gas.
- the cooling module consists of an inner and outer chamber, wherein the outer chamber has perforated layers that allow a transition of cold gas into the food container.
- the cooling module is arranged in the upper region of the food container, so that the cold gas in the food container sinks down and cools the food therein.
- the present invention has for its object, a device of the type mentioned in such a way that the most uniform possible supply of the food container with coolant is achieved in an economical manner.
- This object is achieved in that the cooling module is in communication with a cavity in at least one wall of the food container and the wall on the inside of the food container passage openings from the cavity into the interior of the food container for the escape of coolant into the food container.
- the cooling module is filled with the coolant, in particular liquid carbon dioxide.
- the cooling module is expediently designed so that cold gas produced after the filling operation, in particular carbon dioxide gas generated by sublimation of carbon dioxide snow, is stored.
- the coolant, in particular the cold gas flows into the cavity of the wall of the food container and can be dispensed selectively and metered through the openings in the wall into the interior of the food container.
- the invention can be used in food transport vehicles, which consist of several separate chambers. Usually trays are placed with food in each chamber, which must be kept cold. So far, such tray cars are cooled in a cold air device, the cooling capacity is not always sufficient.
- an economical solution is provided with the invention, can be dispensed with a conventional refrigeration system, which would be expensive to install on the tray car.
- the cooling module which is preferably installed in the food container, acts as a cold reservoir, with a cold transition taking place into the partitions and / or outer walls of the food container.
- the coolant can be dispensed directly and metered from the cavities of the partitions or outer walls via openings directly into the food container.
- the partitions preferably have openings on both sides in order to be able to supply the chambers uniformly with coolant. If the walls have holders for food trays, the openings are preferably provided above the holders. As a result, the introduction of the cold gas above the food, whereby a uniform heat transfer is ensured.
- a coolant supply is expediently connectable to the cooling module, which has a line for liquefied gas, which is in communication with a liquid gas reservoir.
- the liquid gas reservoir is designed as a liquid gas container for carbon dioxide.
- a nozzle / baffle plate system is advantageously provided in the cooling module, flows through the coolant when connected coolant supply, wherein coolant snow and coolant vapor arise.
- the cold gas produced during the filling process can be used as partial flow for pre-cooling the food container.
- the main advantage of the invention is, above all, a uniform distribution of cold in the interior of the food container.
- the invention represents a significant improvement over conventional solutions.
- the use of a device, as described in DE 199 19 934 A1 is problematic in such food containers. Since in the solution proposed there, the cold simply falls from the installed in the upper part of the food container cooling module on the arranged food in the food container, a cooling module would have to be installed in each chamber.
- a single cooling module is sufficient for the cooling of all chambers. Due to the connection between the cooling module and the cavities of the separating and / or outer walls of the food container and the openings in the separating and / or outer walls, a uniform supply of all chambers with a cooling module is possible.
- the separating and / or outer wall surfaces of the food container are cooled moderately, whereby additional convection cold radiation is generated.
- additional convection cold radiation is generated.
- Figure 2 is a schematic diagram for cooling a chamber of a
- the food transport trolley shown in Figure 1 consists of three chambers 1, 2, 3, which are separated by partitions 4, 5 from each other. In each chamber trays not shown in the figure with food can be placed on holders, not shown. The food should be kept cold in the food trolley.
- a cooling module 6 is arranged in the upper region of the food transport vehicle, which can be filled via an adapter 7 for a filling gun with liquid carbon dioxide.
- nozzle / baffle plate system is installed, so that when filling the cooling module 6 CO 2 snow in the cooling module 6 is formed.
- the cooling module 6 can thus also be referred to as a snow box.
- FIG. 2 the principle of cold holding is shown on the basis of a detail from the food transport carriage, which relates to the middle chamber.
- the cooling module 6 (snow box) is supplied via the adapter 7 with liquid carbon dioxide. After filling with sufficient carbon dioxide snow, the filling gun is removed. The carbon dioxide sublimate flows into the cavities of the partitions 4 and 5. About holes in the partitions 4 and 5, the carbon dioxide sublimate in the
- brackets are provided for dining trays. These brackets can be designed for example as beads in the partitions 4 and 5. The holes for the exit of the cold gas are each provided above the brackets 10.
