Abstract

Device for recovering ice crystals has a cooled surface to which the fluid to be frozen is applied. The surface has peaks and troughs, in which the distance between the peaks is less than the extent of one ice crystal. Preferred Features: The surface consists of a hydrophobic material and is coated with such a material.

Description

Die Erfindung betrifft eine Vorrichtung zum Gewinnen von Eiskristallen.The invention relates to a device for the extraction of Ice crystals.

Es sind Vorrichtungen bekannt, beispielsweise aus der DE 29 60 4027, die dazu dienen, eine wässrige Suspension von kleinen Eiskristallen zu gewinnen. Diese Vorrichtungen sind regelmäßig mit einer Einrichtung versehen, die dazu dient, die sich an der gekühlten Fläche bildenden Eiskristalle zu entfernen. Devices are known, for example from DE 29 60 4027, which serve an aqueous suspension of to win little ice crystals. These devices are regularly provided with a facility to do so serves, which forms on the cooled surface To remove ice crystals.  

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrich­ tung zu schaffen, die auf besonders einfache und kosten­ günstige Weise das Gewinnen von Eiskristallen ermöglicht.The invention has for its object a Vorrich to create that at particularly simple and cost favorable way of extracting ice crystals.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vor­ richtung zum Gewinnen von Eiskristallen, mit einer ge­ kühlten Fläche, an der das zu frierende Fluid vorbeige­ führt wird, wobei die gekühlte Fläche derart rauh mit Spitzen und Tälern ausgebildet ist, daß der Abstand zwi­ schen den Spitzen geringer als die kleinste der Erstrec­ kungen der sich bildenden Eiskristalle ist.According to the invention, this object is achieved by a pre direction for extracting ice crystals, with a ge cooled area, where the fluid to be frozen passes is carried out, the cooled surface with such a rough Is formed peaks and valleys that the distance between peaks less than the smallest of the stretches of the ice crystals that form.

Ein bevorzugtes Ausführungsbeispiel zeichnet sich dadurch aus, daß die Fläche aus einem hydrophoben Material besteht oder mit einem solchen beschichtet ist.A preferred embodiment is characterized by this from that the surface is made of a hydrophobic material exists or is coated with such.

Untersuchungen haben gezeigt, daß die sich bildenden Eis­ kristalle bei einer an einer rauhen, gekühlten Fläche vorbeigeführten Fluid sich an den Spitzen der Fläche an­ setzen. 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 on a rough, chilled surface fluid flowing past the tips of the surface put. If the distance between the tips is less than is the extent of a trained ice crystal, prevents them from moving into the "valleys" in the lay rough surface and adhere to it.

Der gewünschte Effekt der Erfindung wird dadurch ver­ stärkt, daß die Fläche aus einem hydrophoben Material oder mit einem solchen beschichtet ist, da bei einer der­ artigen Ausgestaltung keine Adhäsion zwischen Fläche und dem sich bildenden Eiskristallen gegeben ist.The desired effect of the invention is thereby ver strengthens that surface from a hydrophobic material or is coated with such, since one of the like design no adhesion between surface and the ice crystals that form.

Da die Spitzen der rauhen Fläche dem sich an diesem aus­ bildenden Eiskristall 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 der­ art gewählt werden kann, daß der gewünschte Effekt in besonders hohem Maße eintritt.Because the tops of the rough surface are affected by this forming ice crystals do not provide sufficient support, the fluid will entrain them after their formation, so that the ice crystals can be "harvested". It understands  that the flow of the fluid in speed and Direction and other hydraulic properties of the art can be chosen that the desired effect in occurs particularly high.

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 rauhe Tiefe der Oberfläche höher gewählt wer­ den).It is also possible to do this to form ice crystals freezing fluid to add a substance that formation particularly large ice crystals (in this case the rough depth of the surface can be chosen higher the).
