Description

Kühlstab für Speisen und Getränke"Cooling stick for food and drinks "

Die Erfindung betrifft einen Kühistab für Speisen und Getränke, bestehend aus einem Wärmeleitrohr und einem Wärmeaufnehmer.The invention relates to a cooling stick for food and drinks, consisting of from a heat pipe and a heat absorber.

Ein derartiger Kühl stab ist aus der DE-OS 20 27 527 bekannt. Bei diesem bekannten Kiihlstab handelt es sich um eine Wärmeaustauschvorrichtung zur Verwendung in einem Nahrungsmittelbehälter, der in der DE-OS 20 27 527 detailliert beschrieben ist. Diese Wärmeaustauschvorrichtung besteht aus einem länglichen wärmeleitenden Teil aus einem wärmeleitenden Material mit einem ersten und zweiten Ende und mit einem abgeschlossenen hohlen Innenraum. Ein flüssigkeitsgetränkter Docht kleidet die innere Fläche des hohlen Innenraums unter Bildung eines Dampfdurchlasses zwischen dem Docht und dem inneren Teil es abgeschlossenen hohlen Innenraums aus.Such a cooling rod is known from DE-OS 20 27 527. at This known cooling rod is a heat exchange device for Use in a food container, which is detailed in DE-OS 20 27 527 is described. This heat exchange device consists of an elongated thermally conductive Part made of a thermally conductive material with a first and second end and with a closed hollow interior. A wick soaked in liquid dresses the inner surface of the hollow interior to form a vapor passage therebetween the wick and the inner part of it enclosed hollow interior.

Das erste Ende des wärmeleitenden Teils ist mit einem Wärmeaufnehmer verbunden und das zweite Ende ist zugespitzt. Der Wärmeaufnehmer besteht aus einem wärmeleitenden Material und ist mit dem ersten Ende des wärmeleitenden Teils wärmeübertragend verbunden, während dessen zweitea Ende zur Einführung in das Innere von großen Nahrungsmittel stücken zugespitzt ist. Verwendet man die Vorrichtung zum Kühlen von Nahrungsmitteln, wird der Wärmeaufnehmer zu einer Wärmesenke und steht unter der Einwirkung einer Quelle, deren Temperatur geringer ist als diejenige im Inneren des Nahrungsmittels, wie eines Kijhlschranks oder Gefrierapparats.The first end of the thermally conductive part is with a heat absorber connected and the second end is pointed. The heat absorber consists of one thermally conductive material and is heat-transferring to the first end of the thermally conductive part connected, during the second end of the introduction to the interior of large foods pieces is pointed. If the device is used to cool food, the heat absorber becomes a heat sink and is under the influence of a Source, the temperature of which is lower than that inside the food, like a refrigerator or freezer.

Die Erfindung befaßt sich mit dem Problem, daß Speisen, wie z.B. Suppen, Soßen, $Milchgetränke etc.The invention is concerned with the problem that foods such as soups, Sauces, milk drinks etc.

unmittelbar nach dem Kochen zum direkten Genuß viel zu heiß sind, und daß es eine Weile dauert, ehe si< auf eine mundgerechte Temperatur abgekühlt sind, Ähnliches gilt auch für viele Gerichte, die zur weiteren Zubereitung erst abgekühlt (abgeschreckt) werden müssen. Sehr nachteilig ist die lange Abkühlzeit z.B. bei der Zubereitung von Babynahrung, d dic Speise hier auf besonders niedrige Temperatur von 30 bis 40 °C gebracht werden muß.are much too hot for direct enjoyment immediately after cooking, and that it takes a while before it cools down to a bite-sized temperature The same applies to many dishes that have to be prepared further must be cooled down (quenched). The long cooling time is very disadvantageous E.g. when preparing baby food, dic food here on particularly low Temperature of 30 to 40 ° C must be brought.

Aufgabe der Erfindung ist es, einen KiiI 1 stab zu schaffen, mit dessen Hilfe solche Abkühlvorgänge wesentlich beschleunigt werden können und mit dem es auch möglich ist, Speisen auf einer gewünschten Temperatur für eine gewisse Zeit zu halten.The object of the invention is to create a KiiI 1 rod with which Help such cooling processes can be significantly accelerated and with which it It is also possible to put food at a desired temperature for a certain period of time to keep.

Diese Aufgabe wird erfindungsgemäß durch einen Kiihlstab der eingangs genannten Art gelöst, bei dem der Wärmeaufnehmer als Latentwärmespeicher ausgebildet ist. Vorzugsweise ist an dem Wärmeleitrohr ein Wärmetauscher angeordnet. Nach einer bevorzugten Ausführungsform der Erfindung besteht der Latentwärmespeicher aus einem mit einem Speichermittel gefüllten Speicherbehälter. Dabei ist es zweckmäßig, daß im Innern des Speicherbehälters Leitbleche angeordnet sind. Ferner ist es zweckmäßig, daß das Innere des Speicherbehälters mit einem Rohr verbunden ist, das das Wärmeleitrohr konzentriscli umgibt und das ebenfalls Speichermittel enthält.According to the invention, this object is achieved by a cooling rod of the type mentioned at the beginning mentioned type solved, in which the heat absorber designed as a latent heat storage is. A heat exchanger is preferably arranged on the heat pipe. After a preferred embodiment of the invention, the latent heat storage consists of one storage container filled with a storage medium. It is useful that baffles are arranged in the interior of the storage container. It is also useful that the interior of the storage container is connected to a pipe, which is the heat pipe concentric surrounds and also contains storage means.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in a drawing and is described in more detail below.

Die einzige Figur der Zeichnung zeigt einen Kühlstab miteinem Wärmetauscher 1, der über ein Wärmeleitrohr 2 mit einem Latentwärmespeicher 3 thermisch verbunden ist. Der Latentwärmespeicher bzw. Speicherbehälter 3 erstreckt sich in @ in Rohr, das das Wärmeleitrohr 2 konzentrisch umgibt. Im Innern das Speicherbehälters 3 sind Leitbleche 4 angeordnet.The only figure of the drawing shows a cooling rod with a heat exchanger 1, which is thermally connected to a latent heat accumulator 3 via a heat pipe 2 is. The latent heat storage or storage container 3 extends in @ in tube, which surrounds the heat pipe 2 concentrically. Inside the storage container 3 are Baffles 4 arranged.

Taucht man den Wärmetauscher 1 z.B. in eine heiße Suppe ein, vorzugsweise unter Rühren, so nimmt er aus dieser Wärme auf, die dann einer das Wärmeleitrohr 2 in den Latent speicher 3 geführt wird. Das Latentspeichermittel ist ein Stoff (z.B. ein Salzhydrat oder Paraffin), dessen Schmelzpunkt unterhalb der zu kühlenden Speise liegt und der eine möglichst große Schmelzwärme besitzt. Durch die aus der Speist zugefüfrte Wärme kann also der Speicher nur bis zum Schmelzpunkt aufgeheizt werden, da weiter zugeführte Wärme zum Aufschmelzen des Speichermittels aufgezehrt wird. Die Speise wird also sehr wirkungsvoll bis auf <iie Schmelztemperatur des Speichermittels abgefühlt und auch auf dieser Temperatur gehalten, solange noch feste und flüssige Phase gleichzeitig im Speicher vorliegen.If the heat exchanger 1 is immersed, for example, in a hot soup, preferably while stirring, he absorbs heat from this, which then the heat pipe 2 is led into the latent memory 3. The latent storage medium is a substance (e.g. a salt hydrate or paraffin) whose melting point is below that to be cooled Food lies and which has the greatest possible heat of fusion. Through the from the If the heat is fed in, the storage tank can only be heated up to the melting point are consumed, since further supplied heat is used to melt the storage means will. The food is therefore very effective down to the melting point of the The storage medium is sensed and kept at this temperature as long as it is still solid and liquid phase are present in the memory at the same time.

A1s Speichermittel kommen Latentspeichersubstanzen mit möglichst hohen Schmelzwärmen und mit Schmelzpunkten im Bereich von - 30 °C bis -90 °C in Frage, z.B. Paraffine older Salzhydrate und eutektische Mischungen vom Wasser und Salzhydraten. Zur besseren Keimbildung können diesen Stoffen kleine Mengen Keimbildner zugesetzt sein.A1's storage means come with the highest possible latent storage substances Heats of fusion and with melting points in the range from - 30 ° C to -90 ° C are possible, e.g. Paraffins of older salt hydrates and eutectic mixtures of water and salt hydrates. Small amounts of nucleating agents can be added to these substances for better nucleation be.

Kühlstabe, die Speichermittel mit Schmelzpunkten über Raumtemperatur enthalten, werden automatisch wieder regeneriert (Gefrieren des Speichermittels), indem die Schmelzwärme an die Umgebung abgegeben wird. Dagegen müssen Kühlstäbe mit Speichermittel, die erst unter Raumtemperatur gefrieren, im Kühlschrank oder bei noch tieferen Schmelzpunkten des Speichermittels in einem Gefrierfach regeneriert werden.Cooling rods, the storage means with melting points above room temperature are automatically regenerated (freezing of the storage medium), by the Heat of fusion is given off to the environment. Have to counter that Cooling rods with storage media that only freeze below room temperature in the refrigerator or regenerated in a freezer compartment if the melting point of the storage medium is even lower will.
