Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Kühlen oder Einfrieren von Nahrungsmitteln mittels einer kalten Atmosphäre von vernebelter Flüssigkeit in einer . 5 Behandlungskammer, an deren Innenflächen Düsen zur Zerstäubung der Kühlflüssigkeit vorgesehen sind.The invention relates to a device for cooling or freezing of Food by means of a cold atmosphere of nebulized liquid in a . 5 treatment chamber with nozzles on the inner surfaces for atomizing the cooling liquid are provided.

Der Zweck der Erfindung ist eine Verbesserung der Wirkungsweise solcher Vorrichtungen, um die erwünschte Kühlwirkung in kürzerer Zeit zu erreichen und eine Verminderung der für den ständigen Betrieb der Vorrichtung benötigten Menge Vernebelungsflüssigkeit zu ermöglichen. Dies wird gemäß der Erfindung dadurch erreicht, daß in gleicher Höhe mit den Flüssigkeitsdüsen Kühlrohre angeordnet sind. Durch diese Ausbildung ist erreicht, daß die durch die Düsen ■in Umlauf gebrachte vernebelte Kühlflüssigkeit in allen Teilen der Behandlungskammer einer Kühlung unterworfen ist, da die in der Kammer längere Zeit schwebend erhaltenen Flüssigkeitsteilchen, nachdem sie dem zu kühlenden Gut Wärme entzogen haben, an die Kühlrohre gelangen und hier durch Wärmeaustausch wieder auf ihre ursprüngliche niedrige Temperatur gebracht werden. Diese Kühlung der Flüssigkeitsteilchen in der Kammer selbst gewährleistet eine ständige Aufrechterhaltung der richtigen Kühltemperatur in der Behandlungskammer. Ferner ist erreicht, daß nur verhältnismäßig geringe Mengen zu vernebelnder Kühlflüssigkeit für den ständigen Betrieb der Vorrichtung notwendig sind, da die in der Zeiteinheit zu ersetzende Menge an abfließender Kühlflüssigkeit infolge des langen Verharrens der vernebelten und ständig nachgekühlten Flüssigkeitsteilchen sehr klein ist.The purpose of the invention is to improve the operation of such devices, to achieve the desired cooling effect in a shorter time and a reduction the amount of nebulizing liquid required for continuous operation of the device to enable. This is achieved according to the invention in that at the same height as the liquid nozzles Cooling tubes are arranged. This training ensures that the through the nozzles ■ Nebulized coolant circulated in all parts of the treatment chamber is subjected to cooling, since the kept floating in the chamber for a long time Liquid particles, after they have extracted heat from the goods to be cooled, reach the cooling tubes and pass through here Heat exchange can be brought back to its original low temperature. This cooling of the liquid particles in the chamber itself ensures constant Maintaining the correct cooling temperature in the treatment chamber. It is also achieved that only proportionally small amounts of coolant to be atomized for continuous operation of the device are necessary because the amount of cooling liquid that has to be replaced in the unit of time is due to the long persistence of the nebulized and constantly cooled liquid particles is very small.

Die Zeichnung zeigt schematisch eine Ausführungsform des Gegenstandes der Erfindung. The drawing shows schematically an embodiment of the subject matter of the invention.

Es bezeichnet 1 die isolierten Wandungen, an denen Kühlrohrschlangen 2 vorgesehen sind, welchen die Kühlflüssigkeit bei 3 zugeführt und bei 4 entnommen wird.It denotes 1 the insulated walls on which cooling coils 2 are provided are to which the cooling liquid is supplied at 3 and withdrawn at 4.

Ferner sind Rohre 5 vorgesehen, die mit Düsen 6 versehen sind, welche in gleicher Höhe mit den Kühlrohrschlangen 2 liegen. Den Rohren 5 wird die zu vernebelnde Kühlflüssigkeit durch ein Rohr 7 zugeführt, das mit dem Ausgang eines Flüssigkeitsfilters 8 verbunden ist, in den 'die Flüssigkeit aus der Kammer mittels einer Pumpe 10 gefördert wird.Furthermore, pipes 5 are provided which are provided with nozzles 6, which in the same Height with the cooling coils 2 lie. The cooling liquid to be nebulized is fed to the tubes 5 fed through a pipe 7 which is connected to the outlet of a liquid filter 8, into which 'the liquid from the Chamber is promoted by means of a pump 10.

Die nach längerer Umlaufdauer infolge wiederholten Zusammenprallens von Nebelteilchen entstehenden Flüssigkeitstropfen fallen auf einen vorzugsweise nach der Mitte abfallenden Boden 12 und gelangen durch ein Sieb 13 zu einem Behälter 14, der an die Pumpe 10 angeschlossen ist.That after a longer period of rotation as a result of repeated collisions of fog particles The resulting drops of liquid fall onto a bottom 12, preferably sloping towards the middle, and pass through a sieve 13 to a container 14 which is connected to the pump 10.
