Description

Die Erfindung betrifft eine Vorrichtung zur Verteilung gekühlter Speisen, insbesondere für Großküchen, mit einem Bandförderer, einer Anzahl von fahrbaren Speiseverteilergeräten und einer Kälteanlage mit einem geschlossenen Kältemittelkreislauf.The invention relates to a device for distributing refrigerated food, especially for commercial kitchens, with a belt conveyor, a number of mobile food distribution equipment and a refrigeration system with a closed refrigerant circuit.

Bandförderer zur Speisenverteilung im Großküchenbereich sind seit langem bekannt. Diese finden ihren Einsatz in Kantinen, Krankenhäusem, Pflegeheimen und dergleichen. An dem Bandförderer stehen fahrbare Speisenverteilgeräte, z. B. Tellerstapler, Speisenausgabewagen, Tablettstapler und dergleichen. Zur Verteilung gekühlter Speisen, beispielsweise Salaten, Dessert, Cook-Chill-Komponenten und dergleichen, wird in der Praxis regelmäßig die gesamte Umgebung durch eine Raumklimatisierung gekühlt.Belt conveyors for food distribution in the commercial kitchen sector have long been known. These are used in canteens, hospitals, nursing homes and the like. On the belt conveyor are mobile food distribution devices, eg. B. Tellerstapler, food distribution car, tray stacker and the like. In order to distribute chilled foods, for example salads, desserts, cook-chill components and the like, in practice the entire environment is regularly cooled by room air conditioning.

Aus DE 100 45 513 A1 ist ein Bandförderer zum Transport gekühlter Speisen bekannt, der ein wärmegedämmtes Gehäuse sowie eine im Innern des Gehäuses angeordnete Kühlvorrichtung aufweist.Out DE 100 45 513 A1 a belt conveyor for transporting refrigerated food is known, which has a thermally insulated housing and a cooling device arranged in the interior of the housing.

Zur Kühlung der Speisen in den Speiseverteilergeräten müssen diese Geräte mit eigenen Kältemaschinen ausgerüstet werden, vorausgesetzt, dass Kältemittel verwendet werden, die einen geschlossenen Kältemittelkreislauf erfordern. Nur dann bleiben die Speiseverteilergeräte fahrbar. Die Ausrüstung der Speiseverteilergeräte mit eigenen Kälteanlagen ist technisch aufwendig und teuer.To cool the food in the food distribution equipment, these appliances must be equipped with their own refrigeration machines, provided that refrigerants are used that require a closed refrigerant circuit. Only then will the food distribution equipment remain mobile. The equipment of the food distribution equipment with its own refrigeration systems is technically complicated and expensive.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Verteilung gekühlter Speisen anzugeben, die eine technisch einfache und wirksame Kühlung der entlang eines Bandförderers stehenden Speiseverteilergeräte ermöglicht.Against this background, the invention has for its object to provide a device for distributing refrigerated food, which allows a technically simple and effective cooling of standing along a belt conveyor food distribution equipment.

Ausgehend von einer Vorrichtung mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass die Kühlleistung der Kälteanlage auf mehrere Kühlstellen aufteilbar ist, die in Längsrichtung eines Bandförderers angeordnet sind und Einrichtungen zum Anschluss eines Speiseverteilergerätes aufweisen. Bei der Kälteanlage kann es sich um eine externe Anlage oder eine in dem Bandförderer integrierte Kälteanlage handeln, die vorzugsweise als Kompressionskälteanlage ausgebildet ist. Erfindungsgemäß werden die entlang des Bandförderers stehenden Speiseverteilergeräte durch eine Kälteunterverteilung mitversorgt. Die Speiseverteilergeräte bleiben fahrbar und benötigen keine eigene Kältemaschine. Es ergeben sich zahlreiche Möglichkeiten der weiteren Ausgestaltung dieser technischen Lehre.Based on a device having the features described above, the object is achieved in that the cooling capacity of the refrigeration system can be divided into a plurality of cooling points, which are arranged in the longitudinal direction of a belt conveyor and have means for connecting a food distribution device. The refrigeration system can be an external system or a refrigeration system integrated in the belt conveyor, which is preferably designed as a compression refrigeration system. According to the present invention along the belt conveyor food distribution devices are mitversorgt by a cold subdistribution. The distribution boards remain mobile and do not require their own chiller. There are numerous possibilities for the further development of this technical teaching.

Eine bevorzugte Ausführungsform sieht vor, dass der Kältemittelkreislauf in Längsrichtung des Bandförderers sich erstreckende Kältemittelleitungen aufweist und dass an den Kältemittelkreislauf mehrere Verdampfer zur Aufteilung der Kühlleistung auf die Kühlstellen angeschlossen sind. Die Verdampfer sind an der Außenseite des Bandförderers zugänglich und beispielsweise als Lamellen- oder Plattenwärmeaustauscher ausgebildet. Die Speiseverteilergeräte werden an den Verdampfer positioniert und weisen mit dem Verdampfer im Wärmeaustausch stehende Flächen oder Einrichtungen auf. Die Verdampfer können ferner auch in Kühlluftkanälen angeordnet sein, die an einen Kühl- oder Mantellraum der Speiseverteilergeräte anschließbar sind. Vorzugsweise sind die den Kühlstellen zugeordneten Verdampfer einzeln zu- und abschaltbar.A preferred embodiment provides that the refrigerant circuit in the longitudinal direction of the belt conveyor has extending refrigerant lines and that several evaporators are connected to the refrigerant circuit to divide the cooling power to the cooling points. The evaporators are accessible on the outside of the belt conveyor and designed for example as a plate or plate heat exchanger. The food distribution devices are positioned on the evaporator and have surfaces or devices that heat exchange with the evaporator. The evaporators can also be arranged in cooling air ducts which can be connected to a cooling or sheath space of the food distribution devices. Preferably, the evaporators associated with the cooling points are individually switched on and off.

Im Rahmen der Erfindung liegt es auch, dass der Bandförderer ein wärmegedämmtes Gehäuse aufweist, in dem mindestens ein Verdampfer der Kälteanlage und mindestens ein Gebläse angeordnet ist und dass das Gehäuse Auslassöffnungen für Kühlluft aufweist, an die die Speiseverteilergeräte ankoppelbar sind.In the context of the invention, it is also the case that the belt conveyor has a thermally insulated housing in which at least one evaporator of the refrigeration system and at least one fan is arranged and in that the housing has outlet openings for cooling air to which the food distribution devices can be coupled.

Die Kühlstellen können mit Stelleinrichtungen ausgerüstet werden, mit der die Kühlleistung an den Kühlstellen individuell einstell- oder steuerbar ist. In weiterer Ausgestaltung ist vorgesehen, dass die Stelleinrichtungen an eine Zentralsteuerung angeschlossen sind. Mit der Zentralsteuerung sind die Kühlzeiten sowie das Temperaturniveau sowohl des Bandförderers als auch der Speiseverteilergeräte steuer- und gegebenenfalls individuell regelbar. Die Zentralsteuerung ist manuell bedienbar oder programmgesteuert.The cooling points can be equipped with adjusting devices with which the cooling capacity at the cooling points can be set or controlled individually. In a further embodiment it is provided that the adjusting devices are connected to a central control. With the central control, the cooling times and the temperature level of both the belt conveyor and the food distribution devices are tax-controlled and optionally individually.
