Abstract
Vorrichtung zum Gewinnen von Eiskristallen mit einer gekühlten Fläche, an der das zugefrierende Fluid vorbeigeführt wird, dadurch gekennzeichnet, daß die gekühlte Fläche aus einem hydrophoben Material besteht oder mit einem solchen beschichtet ist und mit einer Oberflächenstruktur mit Spitzen und Tälern versehen ist, wobei die Spitzen voneinander einen Abstand aufweisen, der geringer als die Erstreckung eines ausgebildeten Eiskristalls ist.contraption for the extraction of ice crystals with a cooled surface on which the freezing Fluid passed is characterized in that the cooled surface consists of a hydrophobic material or is coated with such and with a surface structure with peaks and valleys is provided, the tips being spaced apart from one another, which is less than the extent of a trained ice crystal is.
Description
Die Erfindung betrifft eine Vorrichtung zum Gewinnen von Eiskristallen mit einer gekühlten Fläche, an der das zu gefrierende Fluid vorbeigeführt wird.The The invention relates to a device for extracting ice crystals with a chilled Area, past which the fluid to be frozen is passed.
Es
sind Vorrichtungen bekannt, beispielsweise auf der
Die Vorrichtungen sind regelmäßig mit einer Einrichtung versehen, die dazu dient, die sich an der gekühlten Fläche bildenden Eiskristalle abzuschaben.The Devices are regularly with provided with a device that serves to form on the cooled surface Scrape off ice crystals.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die auf besonders einfache und kostengünstige Weise das Gewinnen von Eiskristallen ermöglicht.The The invention has for its object to provide a device the extraction of ice crystals in a particularly simple and cost-effective manner allows.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vorrichtung zum Gewinnen von Eiskristallen, mit einer gekühlten Fläche, an der das zu gefrierende Fluid vorbeigeführt wird, wobei die gekühlte Fläche aus einem hydrophoben Material besteht oder mit einem solchen beschichtet ist und mit einer Oberflächenstruktur mit Spitzen und Fälern versehen ist, wobei die Spitzen voneinander einen Abstand aufweisen, der geringer als die Erstreckung eines ausgebildeten Eiskristalls ist.According to the invention Task solved by a device for extracting ice crystals, with a cooled surface which is passing the fluid to be frozen, taking the cooled area out consists of or coated with a hydrophobic material is and with a surface structure with tips and forgers is provided, the tips being spaced from one another, which is less than the extent of a trained ice crystal is.
Untersuchungen haben gezeigt, daß die sich bildenden Eiskristalle bei einem einer rauhen, gekühlten Fläche vorbeigeführten Fluid sich an den Spitzen der Fläche ansetzen. Bei einem Abstand der Spitzen, der geringer als die Erstreckung eines ausgebildeten Eiskristalls ist, wird verhindert, daß diese sich in die "Täler" in der rauhen Oberfläche legen und in diesen haften.investigations have shown that the ice crystals that form when a fluid is guided past a rough, cooled surface themselves at the tops of the area begin. If the distance between the tips is less than the extension of a trained ice crystal is prevented from forming lay in the "valleys" in the rough surface and stick to them.
Der gewünschte Effekt der Erfindung wird dadurch verstärkt, daß die Fläche aus einem hydrophoben Material besteht oder mit einem solchen beschichtet ist, da bei einer derartigen Ausgestaltung keine Adhäsion zwischen der Fläche und den sich bildenden Eiskristallen gegeben ist.The desired Effect of the invention is enhanced in that the surface made of a hydrophobic material exists or is coated with such, since such Design no adhesion between the surface and given the ice crystals that form.
Da die Spitzen der rauhen Fläche den sich an diesem ausbildenden Eiskristallen keinen ausreichenden Halt bieten, wird das Fluid diese nach deren Bildung mitreißen, so daß die Eiskristalle "geerntet" werden können. Es versteht sich, daß die Strömung des Fluids in Geschwindigkeit und Richtung sowie sonstiger hydraulischer Eigenschaften derart gewählt werden kann, daß der gewünschte Effekt in besonders hohem Maße eintritt.There the tips of the rough surface not sufficient enough on this forming ice crystals Provide support, the fluid will carry them away after their formation, so that the Ice crystals can be "harvested". It it is understood that the Flow of Fluids in speed and direction as well as other hydraulic Properties can be selected in this way can that the desired Effect in a particularly high degree entry.
Es ist auch möglich, dem zur Bildung von Eiskristallen zu frierenden Fluid eine Substanz zuzugeben, die die Bildung besonders großer Eiskristalle bewirkt (in diesem Fall kann die Rauhtiefe der Oberfläche größer gewählt werden).It is possible, too, the fluid to be frozen to form ice crystals is a substance admit, which causes the formation of particularly large ice crystals (in In this case the surface roughness can be chosen larger).
