Abstract
Description
Die Erfindung betrifft einen Kochkessel zur Zubereitung von Lebensmitteln nach dem Oberbegriff des Anspruchs 1.The invention relates to a cooking kettle for the preparation of food according to the preamble of claim 1.
Bei der Zubereitung von Speisen in Gemeinschaftsverpflegungseinrichzungen, beispielsweise Kantinen, werden gattungsgemäße Kochkessel eingesetzt, um große Mengen von Speisen zuzubereiten. Die Speisen werden dabei in ein Rührgefäß des Kochkessels eingefüllt, in dem ein rotatorisch antreibbares Rührwerk vorgesehen ist. Durch geeignete Maßnahmen, beispielsweise den Durchfluss eines Wärmeübertragungsmediums durch die Wandung des Rührgefäßes, kann die Speisemasse zugleich auch erwärmt und damit gegart werden. Außerdem ist es bei bekannten Kochkesseln auch möglich, die Speisemasse nach dem Garen im Kochkessel zu kühlen, um damit eine schnellere Abkühlung der Speisemasse und eine entsprechend höhere Haltbarkeit zu erreichen.When preparing food in communal catering facilities, such as canteens, generic cauldrons are used to prepare large quantities of food. The dishes are filled in a mixing vessel of the cooking kettle, in which a rotatably drivable agitator is provided. By suitable measures, for example the flow of a heat transfer medium through the wall of the mixing vessel, the feed mass can also be heated and cooked with it at the same time. In addition, it is also possible with known cooking kettles to cool the feed mass after cooking in the cooking kettle in order to achieve a faster cooling of the feed mass and a correspondingly higher durability.
Um die Heiz- bzw. Kühlleistung zu erhöhen, sind gattungsgemäße Kochkessel mit einem zusätzlichen Wärmetauscher ausgestattet, der im Inneren des Kochgefäßes derart angeordnet wird, dass er in unmittelbaren Kontakt mit der Speisemasse kommt. Ein derartiger Kochkessel ist beispielsweise aus der
Da die Wärmetauscher der bekannten Kochkessel in unmittelbaren Kontakt mit der Speisemasse kommen, ist eine Reinigung der Wärmetauscher nach Abschluss des jeweiligen Zubereitungsprozesses erforderlich. Zum Reinigen der Wärmetauscher ist es bei den bekannten Kochkesseln notwendig, den Wärmetauscher von Hand aus dem Rührgefäß herauszuheben. Diese Art der manuellen Handhabung der Wärmetauscher ist umständlich, kann bei schweren Wärmetauschern zu gesundheitlichen Beeinträchtigungen führen und verringert insgesamt die Akzeptanz durch das Bedienpersonal.Since the heat exchangers of the known cooking kettle come into direct contact with the feed mass, a cleaning of the heat exchanger after completion of the respective preparation process is required. To clean the heat exchanger, it is necessary in the known cooking kettles to lift the heat exchanger by hand from the mixing vessel. This type of manual handling of the heat exchanger is cumbersome, can lead to health problems in heavy heat exchangers and reduces the overall acceptance by the operating personnel.
Ausgehend von diesem Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung, einen neuen Kochkessel zur Zubereitung von Lebensmitteln unter Einsatz eines Wärmetauschers im Rührgefäß vorzuschlagen, der einen höheren Bedienkomfort aufweist.Based on this prior art, it is therefore an object of the present invention to propose a new cooking vessel for the preparation of food using a heat exchanger in the mixing vessel, which has a higher ease of use.
Diese Aufgabe wird durch einen Kochkessel nach der Lehre des Anspruchs 1 gelöst.This object is achieved by a cooking kettle according to the teaching of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Der erfindungsgemäße Kochkessel beruht auf dem Grundgedanken, dass am Kochkessel eine Handhabungsvorrichtung vorgesehen ist, mit der der Wärmetauscher bedient werden kann. So ermöglicht die erfindungsgemäße Handhabungsvorrichtung insbesondere ein Bewegen des Wärmetauschers zwischen der Betriebsposition im Kochkessel und einer Reinigungsposition außerhalb des Kochkessels, so dass das manuelle Herausheben des Wärmetauschers aus dem Kochkessel entfällt. Im Ergebnis wird also das Bedienpersonal bei der Handhabung des Wärmetauschers zu Reinigungszwecken durch die erfindungsgemäße Handhabungsvorrichtung massiv unterstützt.The cooking kettle according to the invention is based on the idea that a cooking device is provided on the cooking vessel, with which the heat exchanger can be operated. Thus, the handling device according to the invention makes it possible in particular to move the heat exchanger between the operating position in the cooking kettle and a cleaning position outside the cooking kettle, so that the manual lifting of the heat exchanger from the cooking kettle is dispensed with. As a result, so the operator in the handling of the heat exchanger massively supported for cleaning purposes by the handling device according to the invention.
Die Bauart der Handhabungsvorrichtung zur Handhabung des Wärmetauschers ist grundsätzlich beliebig, solange die erfindungsgemäße Beweglichkeit zwischen der Betriebsposition und der Reinigungsposition gewährleistet ist. Nach einer bevorzugten Ausführungsform der Erfindung ist die Handhabungsvorrichtung in der Art einer Schwenkvorrichtung, insbesondere in der Art eines am Kochkessel gelagerten Schwenkarms, ausgebildet. Derartige Schwenkvorrichtungen können mit sehr einfachen Mitteln und damit kostengünstig realisiert werden.The design of the handling device for handling the heat exchanger is basically arbitrary, as long as the mobility according to the invention between the operating position and the cleaning position is ensured. According to a preferred embodiment of the invention, the handling device in the manner of a pivoting device, in particular in the manner of a cooking arm mounted on the cooking arm, is formed. Such pivoting devices can be realized with very simple means and thus cost.
In welcher Weise die Handhabungsvorrichtung angetrieben wird, ist grundsätzlich beliebig. So sind manuell antreibbare Handhabungsvorrichtungen, beispielsweise unter Verwendung entsprechender Umlenkgetriebe und Hebelmechanismen, denkbar, die eine kraftschonende Handhabung des Wärmetauschers ermöglichen. Besonders vorteilhaft ist es, wenn die Handhabungsvorrichtung mit einer Antriebseinrichtung ausgestattet ist, beispielsweise mit einem elektromotorischen Antrieb. Insbesondere bei schweren Wärmetauschern sind solche elektromotorischen Antriebseinrichtungen von Vorteil, da die mechanischen Übertragungseinrichtungen vielfach nicht ausreichen, das erforderliche Kraftniveau zur Verstellung des Wärmetauschers auf ein unter Komfortgesichtspunkten tolerierbares Maß zu begrenzen.The way in which the handling device is driven is fundamentally arbitrary. Thus, manually drivable handling devices, for example using appropriate deflection gear and lever mechanisms, conceivable that allow a power-saving handling of the heat exchanger. It when the handling device is equipped with a drive device, for example with an electric motor drive is particularly advantageous. Particularly in the case of heavy heat exchangers, such electromotive drive devices are advantageous, since the mechanical transmission devices are often insufficient to limit the required force level for adjusting the heat exchanger to a level which is tolerable under the aspect of comfort.
Je nach Bedarf an Speisemenge kann der Füllgrad des erfindungsgemäßen Kochkessels erheblich variieren. Um trotz der daraus resultierenden Niveauunterschiede bei der Füllung des Kochkessels immer eine optimale Kühl- bzw. Heizleistung mit dem Wärmetauscher erreichen zu können, ist es besonders vorteilhaft, wenn der Wärmetauscher höhenverstellbar an der Handhabungsvorrichtung gelagert ist. In der Betriebsposition des Wärmetauschers kann dann das Höhenniveau des Wärmetauschers relativ zur Handhabungsvorrichtung verändert und damit der Wärmetauscher im Kochkessel angehoben bzw. abgesenkt werden, so dass sich im Ergebnis eine optimale Positionierung des Wärmetauschers relativ zur Speisemasse ergibt. Im Ergebnis kann also durch die höhenverstellbare Lagerung des Wärmetauschers erreicht werden, dass die positionierung des Wärmetauschers auf den jeweiligen Füllgrad des Kessels optimal abgestimmt werden kann.Depending on the required amount of food, the degree of filling of the cooking vessel according to the invention can vary considerably. In order to always be able to achieve optimum cooling or heating power with the heat exchanger despite the resulting differences in level in the filling of the cooking kettle, it is particularly advantageous if the heat exchanger is mounted vertically adjustable on the handling device. In the operating position of the heat exchanger then the height level of the heat exchanger can be changed relative to the handling device and thus the heat exchanger can be raised or lowered in the cooking vessel, so that as a result an optimal positioning of the heat exchanger relative to the feed mass results. As a result, it can thus be achieved by the height-adjustable mounting of the heat exchanger, that the positioning of the heat exchanger can be optimally adapted to the respective degree of filling of the boiler.
Soweit der Kochkessel mit einem Deckel verschließbar ausgebildet sein soll, ist es besonders vorteilhaft, wenn der Deckel an der Oberseite des Wärmetauschers vorgesehen ist. Durch Anordnung des wärmetauschers in seiner Betriebsposition wird dann zugleich eine Schließung des Kochkessels durch den am Wärmetauscher befestigten Deckel realisiert.As far as the cauldron is to be formed closable with a lid, it is particularly advantageous if the lid is provided at the top of the heat exchanger. By arranging the heat exchanger in its operating position, a closure of the cooking vessel is then realized by the lid attached to the heat exchanger at the same time.
Alternativ bzw. additiv zur Befestigung eines Deckels kann am Wärmetauscher auch ein Eingriffsschutz, beispielsweise ein Gitterrohr, vorgesehen sein. Durch diesen Eingriffsschutz kann der Zugriff von außen in den Kochkessel versperrt werden, um die vom Rührwerk ausgehende Verletzungsgefahr zu vermindern.Alternatively or in addition to the attachment of a lid, an engagement protection, for example a grid tube, may be provided on the heat exchanger. This intrusion protection can block access from the outside to the cooking kettle in order to reduce the risk of injury from the agitator.
Bei dem erfindungsgemäßen Kochkessel ist es vorgesehen, dass der Wärmetauscher zwischen seiner Betriebsposition im Kochkessel und einer Reinigungsposition verstellt, insbesondere verschwenkt, werden kann. Die Stellung des Wärmetauschers in der Reinigungsposition, die zum Einschwenken in die Betriebsposition notwendig ist, ist vielfach für die Reinigung des Wärmetauschers in der Reinigungsposition nicht optimal. Um die Reinigung des Wärmetauschers in der Reinigungsposition noch weiter zu erleichtern, ist es deshalb besonders vorteilhaft, wenn der Wärmetauscher verstellbar, insbesondere drehbar, an der Handhabungsvorrichtung gelagert ist. Dadurch ist es dann möglich, dass der Wärmetauscher in der Reinigungsposition zwischen einer Wartestellung, die das Verstellen, insbesondere Verschwenken, des Wärmetauschers in die Betriebsposition ermöglicht, und einer Reinigungsstellung, die für die Reinigung des Wärmetauschers optimal ist, verstellt, insbesondere verschwenkt, werden kann.In the cooking kettle according to the invention, it is provided that the heat exchanger between its operating position in the cooking vessel and a cleaning position adjusted, in particular pivoted, can be. The position of the heat exchanger in the cleaning position, which is necessary for pivoting into the operating position, is often not optimal for cleaning the heat exchanger in the cleaning position. In order to facilitate the cleaning of the heat exchanger in the cleaning position still further, it is therefore particularly advantageous if the heat exchanger is adjustable, in particular rotatable, mounted on the handling device. This makes it possible that the heat exchanger in the cleaning position between a waiting position, which allows the adjustment, in particular pivoting, of the heat exchanger in the operating position, and a cleaning position, which is optimal for the cleaning of the heat exchanger, adjusted, in particular pivoted, can ,
Um Verschmutzungen in der Umgebung des Kochkessels durch die Reinigung des Wärmetauschers weitgehend zu vermeiden, kann am Kochkessels eine Auffangschale vorgesehen werden. Diese Auffangschale wird dabei so angeordnet, dass sie sich unterhalb des Wärmetauschers in dessen Reinigungsstellung befindet.To avoid contamination in the vicinity of the cooking vessel by cleaning the heat exchanger largely, a drip tray can be provided on the cooking kettle. This drip tray is arranged so that it is located below the heat exchanger in its cleaning position.
Um die Lage der Auffangschale optimal auf die Lage des zu reinigenden Wärmetauschers abstimmen zu können, ist es besonders vorteilhaft, wenn die Auffangschale verstellbar am Kochkessel gelagert ist.In order to be able to optimally coordinate the position of the drip tray to the position of the heat exchanger to be cleaned, it is particularly advantageous if the drip tray is adjustably mounted on the cooking kettle.
Um eine besonders große Kühl- bzw. Heizfläche zu realisieren, sollte der Wärmetauscher mehrere konzentrisch angeordnete Ringabschnitte aufweisen, durch die das Heiz- bzw. Kühlmedium hindurchgepumpt werden kann.In order to realize a particularly large cooling or heating surface, the heat exchanger should have a plurality of concentrically arranged ring sections, through which the heating or cooling medium can be pumped.
Zwischen den einzelnen Ringen des Wärmetauschers können sich dabei Abstreifer befinden, die insbesondere zum rotatorischen Antrieb am Rührwerk des Rührkessels zum Eingriff gebracht werden. Die Abstreifer selbst können dabei schräg nach unten geneigt sein, um im Speisebrei eine nach unten gerichtete Strömung zu erzeugen.There may be scrapers between the individual rings of the heat exchanger, which are brought into engagement in particular for the rotary drive on the agitator of the stirred tank. The scrapers themselves can be inclined downwards to produce a downward flow in the chyme.
Um den Wärmetauscher in einfacher Weise in seiner Betriebsposition im Kochkessel fixieren zu können, ist es besonders vorteilhaft, wenn am Wärmetauscher eine mittlere Hohlachse vorgesehen ist. Diese Hohlachse kann dann von oben auf die Achse des Rührwerks im Kochkessel aufgesteckt und damit eine Zentrierung des Wärmetauschers realisiert werden. Soweit als Handhabungsvorrichtung ein Gelenkarm vorgesehen ist, kann durch die Verwendung der Hohlachse außerdem in einfacher Weise realisiert werden, dass der Wärmetauscher mit der Hohlachse von oben auf das Rührwerk aufgesteckt und dadurch geführt wird.In order to fix the heat exchanger in a simple manner in its operating position in the cooking kettle, it is particularly advantageous if a central hollow shaft is provided on the heat exchanger. This hollow shaft can then be plugged from the top of the axis of the agitator in the cooking vessel and thus a centering of the heat exchanger can be realized. As far as an articulated arm is provided as a handling device, can also be realized by the use of the hollow shaft also in a simple manner that the heat exchanger is attached to the hollow shaft from above the agitator and thereby guided.
Da der Wärmetauscher des erfindungsgemäßen Kochkessels durch die Handhabungsvorrichtung in einer fest vorgegebenen Relativanordnung zum Kochkessel steht, kann die Kühl- bzw. Heizmediumversorgung in einfacher Weise realisiert werden. Insbesondere können zur Versorgung des Wärmetauschers mit dem erforderlichen Heiz- bzw. Kühlmedium einfach Schläuche eingesetzt werden, die zwischen dem Wärmetauscher einerseits und entsprechenden Zuläufen andererseits anzuschließen sind.Since the heat exchanger of the cooking vessel according to the invention by the handling device is in a fixed predetermined relative arrangement to the cooking vessel, the cooling or heating medium supply in be realized in a simple manner. In particular, can be used to supply the heat exchanger with the required heating or cooling medium simply hoses to be connected between the heat exchanger on the one hand and corresponding inlets on the other.
Eine weitere Verbesserung des Wärmeübergangs ergibt sich, wenn der Wärmetauscher in der Art eines Gegenstromwärmetauschers ausgebildet ist. Bei einem solchen Cregenstromwärmetauscher sind jeweils zumindest zwei getrennte Kanäle vorgesehen, die insbesondere jeweils in der Art konzentrischer Ringkanäle ausgebildet sein können. In den beiden Kanälen strömt das Wärmeübertragungsmedium dann in jeweils entgegengesetzte Richtungen, so dass die verschiedenen Wärmetauscherabschnitte damit jeweils zweimal vom Wärmeübertragungsmedium durchströmt werden.A further improvement of the heat transfer results when the heat exchanger is designed in the manner of a countercurrent heat exchanger. In such a Cregenstromwärmetauscher each at least two separate channels are provided, which may be formed in each case in particular in the manner of concentric annular channels. In the two channels, the heat transfer medium then flows in opposite directions, so that the heat exchanger medium flows through the various heat exchanger sections twice in each case.
Um eine Kühlung der Speisemasse zu erreichen, ist es besonders vorteilhaft, wenn der Zulauf des Wärmetauschers an ein Kühlmedium, insbesondere Eiswasser, Glykol-Wasser-Mischung oder eine Wasser-Eis-Mischung, zur Versorgung mit Kühlmittel angeschlossen ist.In order to achieve a cooling of the feed mass, it is particularly advantageous if the inlet of the heat exchanger to a cooling medium, in particular ice water, glycol-water mixture or a water-ice mixture, is connected to the supply of coolant.
Um eine Beheizung des Kochkessels zu erreichen, kann über den Zulauf ein Heizmedium, insbesondere Heißwasser oder Heißdampf, zugeführt werden.In order to achieve heating of the cooking vessel, a heating medium, in particular hot water or superheated steam, can be supplied via the inlet.
