Description
Die Erfindung betrifft einen Dünnschichtkühler nach dem Oberbegriff des Anspruches 1.The invention relates to a thin-film cooler according to the preamble of claim 1.
Derartige Dünnschichtkühler sind in den unterschiedlichsten Ausgestaltungen bekannt. Sie werden nicht nur als Wärmetauscher bei der Herstellung von fetthaltigen Nahrungsmitteln, sondern auch- zur Bearbeitung und Herstellung folgender Stoffe eingesetzt: Schokoladen- und Kakaomassen, Fettglasur und Kakaobutter, Erdnussbutter, Nuss- und Mandelmassen, Fruchtsäften, Spirituosen, Cremes und Kosmetika, Produkte der chemischen und pharmazeutischen Industrie, Lacke, Farben und Wachse, Schmieröle und Schmierfette, monomere und polymere flüssige Kunststoffe.Such thin-film coolers are known in a wide variety of designs. They are not only used as heat exchangers in the production of fatty foods, but also for the processing and production of the following substances: chocolate and cocoa masses, fat glaze and cocoa butter, peanut butter, nut and almond masses, fruit juices, spirits, creams and cosmetics, products from the chemical and pharmaceutical industries, varnishes, paints and waxes, lubricating oils and greases, monomeric and polymeric liquid plastics.
Die Anwendungsgebiete sind vielschichtig. Bei den bekannten Wärmetauschern besteht die Gefahr, daß sich das Produkt an den Wandungen des Rotors und des Stators aufbaut. Das geschieht durch Separation von Feststoffen von den Flüssig-The areas of application are diverse. With the known heat exchangers there is a risk that the product will build up on the walls of the rotor and stator. This happens by separating solids from the liquids.
bestandteilen bei Mischungen oder Viskositätsänderungen. Bei fetthaltigen Gemischen bilden sich Fettkristalle an den Wandungen. Dadurch wird der Wärmeübergang laufend schlechter. Es kann sogar zu Verstopfungen kommen. Bekannt ist es, die Krusten durch Abstreifer laufend mechanisch zu entfernen. Dieses bedeutet einen höheren maschinellen Aufwand. Die Abstreifer und die Wandungen vom Rotor verschleissen. Es kommt zu Maschinenstillständen. Weiterhin liegt ein höherer Energieverbrauch vor.components in mixtures or viscosity changes. Fat crystals form on the walls of mixtures containing fat. This makes heat transfer increasingly poor. Blockages can even occur. It is well known that the crusts are continuously removed mechanically using scrapers. This means more mechanical effort. The scrapers and the walls of the rotor wear out. This leads to machine downtime. There is also higher energy consumption.
Der Erfindung liegt die Aufgabe zugrunde, einen Dünnschichtkühler der eingangs genannten Art zu schaffen, der ohne Abstreif er ""auskommt und" dennoch'mit "einem hohen Wirkungsgrad und einer langen Lebensdauer arbeitet. Diese Augabe wird grundsätzlich durch das Kennzeichen des Anspruches gelöst.The invention is based on the task of creating a thin-film cooler of the type mentioned at the beginning, which does not require stripping and yet operates with a high degree of efficiency and a long service life. This task is basically solved by the characterizing part of the claim.
Dadurch, daß die verschleissfeste, anorganische Antihaftbeschichtung an den entsprechenden Flächen, die den Spalt zwischen Rotor und Stator begrenzen, vorgesehen ist, wird praktisch ein Verkrusten und ein Absetzen von Produktbestandteilen vermieden. Das Material weist eine hohe Abriebfestigkeit und eine völlige Geschmacksneutralität auf. Letzteres ist insbesondere bei der Behandlung von Nahrungsmitteln wichtig.Because the wear-resistant, inorganic non-stick coating is provided on the corresponding surfaces that delimit the gap between the rotor and stator, encrustation and settling of product components is practically avoided. The material has a high abrasion resistance and is completely taste-neutral. The latter is particularly important when processing food.
In den Unteransprüchen sind vorteilhafte Ausgestaltungen unter Schutz gestellt.Advantageous embodiments are protected in the subclaims.
Grundsätzlich ist es auch möglich, den Dünnschichtkühler zum Erwärmen entsprechender Produkte einzusetzen (Anspruch 7).In principle, it is also possible to use the thin-film cooler to heat corresponding products (claim 7).
Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles erläutert.In the following, the invention is explained using an embodiment example with reference to the drawing.
In der einzigen Figur ist. schematisch eine Ausführungsform eines Dünnschichtkühlers dargestellt. Dieser besteht aus einem vertikal angeordneten, doppelwandigen Kühlzylinder, der den Stator 1 bildet. Der Stator 1 ist oben mit einer die Lager 4 für den Rotor 2 tragenden Abdeckplatte 14 versehen. The single figure shows a schematic embodiment of a thin-film cooler. This consists of a vertically arranged, double-walled cooling cylinder that forms the stator 1. The stator 1 is provided at the top with a cover plate 14 that supports the bearings 4 for the rotor 2.
In dem Stator 1 rotiert der Rotor 2, der mit Hilfe der Lager 4 und seiner Antriebswelle 16 fliegend gelagert ist. Der Antrieb erfolgt mit Hilfe eines Elektromotors über ein Getriebe 6, evtl. auch mit Direktantrieb (Stellmotore oder frequenzgesteuerte Antriebsmotore).The rotor 2 rotates in the stator 1 and is supported by the bearings 4 and its drive shaft 16. The drive is provided by an electric motor via a gear 6, possibly also with a direct drive (servomotors or frequency-controlled drive motors).
Durch den Hohlraum 17, der als Hohlwelle 16 ausgebildeten Antriebswelle, führt das Kühlrohr 5 in den Innenraum des Rotors 2. An dem oberen Ende des Kühlrohres 5 ist eine Drehverbindung 7 angeordnet, durch die der Kühlmittelzufluss ein- und ausgeschaltet werden kann.. Der Kühlmitteleintritt ist mit 12 und der Kühlmittelaustritt mit 13 bezeichnet.. The cooling pipe 5 leads through the cavity 17 of the drive shaft designed as a hollow shaft 16 into the interior of the rotor 2. A rotary joint 7 is arranged at the upper end of the cooling pipe 5, through which the coolant flow can be switched on and off. The coolant inlet is designated 12 and the coolant outlet is designated 13.
Der Stator 1 bildet ein doppelwandiges Gehäuse, in dessen Innenraum bei 1.0 Kühlmittel zu- und bei 11 Kühlmittel abgeführt wird. Im unteren Bereich ist der den Kühlzylinder bildende Stator 1 bei 15 konisch ausgebildet.The stator 1 forms a double-walled housing, into the interior of which coolant is added at 1.0 and coolant is removed at 11. In the lower area, the stator 1, which forms the cooling cylinder, is conical at 15.
Das zu kühlende und zu behandelnde Produkt tritt bei 8 ein und bei 9 wieder aus.The product to be cooled and treated enters at 8 and exits at 9.
Das Produkt strömt durch den Spalt 3 zwischen Rotor und Stator und wird an den mit einer verschleissfesten, anorganischen Antihaftbeschichtung versehenen Beschichtung gekühlt. Vorzugsweise wird hier als Beschichtung eine solche auf der Basis von MetaIl/Metalloxid eingesetzt. Durch diese Beschichtung wird vermieden, dass das zu kühlende Produkt sich absetzt oder verkrustet. Das Produkt wird an den be-The product flows through the gap 3 between the rotor and stator and is cooled on the coating provided with a wear-resistant, inorganic non-stick coating. Preferably, a coating based on metal/metal oxide is used here. This coating prevents the product to be cooled from settling or encrusting. The product is cooled on the
schichteten Flächen gekühlt und nimmt eine niedrigere Temperatur und damit im allgemeinen eine höhere Viskosität an. Der Kühleffekt lässt sich durch die Regelung des Förderstromes und Temperierung des Kühlmittels (±) beeinflussen.The coolant is cooled by the layered surfaces and assumes a lower temperature and therefore generally a higher viscosity. The cooling effect can be influenced by regulating the flow rate and the temperature of the coolant (±).
Wenn eine Erwärmung des Produktes gewünscht wird, kann anstelle des Kühlmittels auch ein Mittel zum Erwärmen zugeführt werden. Als Kühlmittel kommt Wasser oder auch ein anderes Kühlmittel, z.B. eine Sole, infr.age.If heating of the product is desired, a heating agent can be added instead of the coolant. The coolant can be water or another coolant, e.g. brine, infr.age.
