Wenn Wasser zu Blöcken genügend großer Abmessungen gefriert, so nimmt der mittlere Teil, der stets zuletzt fest wird, niemals die Durchsichtigkeit und Klarheit der äußeren Schichten an. Um die Bildung dieses dunklen Kernes zu vermeiden, ist man jetzt dazu übergegangen, destilliertes Wasser anzuwenden. Dieses Verfahren bietet aber gewisse Nachteile dar und macht die Herstellung von Eisblöcken ohne dunklen Kern sehr teuer, weil eben destilliertes Wasser verwendet werden muß.When water freezes into blocks of sufficiently large dimensions, the middle one increases Part that always becomes solid in the end, never the transparency and clarity of the outer one Layers on. In order to avoid the formation of this dark core, one has now proceeded to use distilled water. However, this method has certain disadvantages and makes the production of ice blocks very expensive without a dark core because distilled water has to be used.

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Eisblöcken, welches die Gewinnung kernloser Eisblöcke von jeder beliebigen Dicke gestattet, ohne daß hierzu destilliertes Wasser benutzt werden muß. Das Verfahren beruht auf der Beobachtung, daß das durch Schmelzen des Eises erhaltene Wasser bei einem erneuten Frieren einen vollkommenThe present invention relates to a method for producing ice blocks, which the extraction of coreless ice blocks of any thickness allowed without this distilled water must be used. The method is based on the observation that the water obtained by melting the ice is perfect when it freezes again

ao durchsichtigen und kernlosen Eisblock liefert. Auf der Erkenntnis dieser Tatsache beruht das vorliegende Verfahren und die Vorrichtung zur Ausführung desselben. Das Verfahren besteht im wesentlichen darin, daß das Wasser, welches im Innern eines Eisblockes kurz vor Beendigung des Gefrierens bleibt und welches einen dunklen Kern liefern würde, in dem Augenblicke, wo es eingeschlossen werden würde, durch sehr kaltes Wasser, welches von der Verflüssigung von Eis herrührt, ersetzt wird. Dieses Wasser wird unmittelbar fest, indem es sich mit dem schon gebildeten Eise, welches es umgibt, vereinigt und so einen homogenen Block ohne dunklen Kern liefert.ao provides clear and coreless ice block. That is based on the knowledge of this fact present method and apparatus for carrying out the same. The procedure persists essentially in the fact that the water, which is inside a block of ice shortly before termination of freezing remains and which would provide a dark core the moment it becomes trapped would be replaced by very cold water resulting from the liquefaction of ice will. This water becomes solid immediately, as it becomes with the already formed ice, which surrounds it, unites it and thus provides a homogeneous block without a dark core.

Die in der beiliegenden Zeichnung dargestellte Vorrichtung zur Ausführung des vorliegenden Verfahrens besteht im wesentlichen aus einem Behälter i, der mit einer nicht gefrierenden Flüssigkeit angefüllt ist. In dem Behälter 1 befindet sich eine Schlange 2 für Ammoniak, ein Rührer 3 und eine beliebige Anzahl von Formen 4, welche für die Erzeugung der Eisblöcke bestimmt sind.The device shown in the accompanying drawing for carrying out the present Method consists essentially of a container i, which is equipped with a non-freezing Liquid is full. In the container 1 there is a queue 2 for Ammonia, a stirrer 3 and any number of molds 4 necessary for the generation the ice blocks are determined.

In die Achse jeder der Formen taucht ein Rohr 5. Diese einzelnen Rohre werden mit Hülfe einer schnell anzubringenden Muffe 6 mit einem Rohre η verbunden. Das Rohr 7 öffnet sich in den unteren Teil eines zweiten Behälters 8. In das Rohr 7 ist eine Pumpe 9 eingeschaltet.A tube 5 is immersed in the axis of each of the molds. These individual tubes are connected to a tube η with the aid of a sleeve 6 that can be quickly attached. The tube 7 opens into the lower part of a second container 8. In the tube 7, a pump 9 is switched on.

In den Behälter 8 ist eine Schlange 10 sowie ein Rührer 11 eingebaut. Die beiden Enden dieser Schlangen sind mit zwei Zweiweghähnen 12 verbunden, durch welche man hintereinander Ammoniak zum Gefrieren des Inhalts des Behälters 8 oder warmes Wasser zum Schmelzen des Eises einführen kann.A snake 10 and a stirrer 11 are built into the container 8. The two ends these snakes are connected to two two-way taps 12, through which one one after the other ammonia to freeze the contents of the container 8 or warm water can introduce to melt the ice.

Die Wirkungsweise der beschriebenen Vorrichtung ist die folgende:The operation of the device described is as follows:

Claims

Water and then leads the freezing agent (ammonia or the like.) In the queue 2, while at the same time the stirrer 3 is in action. When the water of the molds has almost finished freezing, i. H. if only a small amount of water remains in the center of a thick layer of ice, this water is sucked in by the pump 9 and returned to the container 8. Here, this water is frozen by introducing ammonia into the coil 10. The ice that forms around the latter is completely transparent if the mass is stirred continuously throughout the freezing process. As soon as the freezing process has ended, warm water is fed into the line 10 with the aid of the two-way taps 12. The warm water causes the ice to melt. This melt water is returned to the molds 4, where it freezes immediately in contact with the ice, which almost completely fills the molds. A completely homogeneous block of ice without a dark core is thus obtained. The water which is introduced into the snake 10 to melt the ice should advantageously only be so warm that the ice melts without the water obtained being unnecessarily heated. Ice can be made continuously from the water obtained by melting the ice. Immediately fill in the empty space left in the middle of the blocks in the molds and immediately remove the water left in the middle. Ρλτεν τ claims:

1. Method of creating ice blocks without a dark core, characterized in that one first cools a certain amount of water so far that a almost complete freezing of the mass occurs with the exception of the middle part, which Unfrozen water is removed from the middle part of the block and replaced by water, which results from the melting of formed ice, replaced during the Constant stirring is carried out during freezing.

2. Apparatus for carrying out the method according to claim 1, characterized by two containers (1, 8), one of which container (1) the molds (4) for the Receives ice blocks and is provided with cooling tube (2) and stirrer (3), while the Shapes (4) have tubes (5) on their axis, which are connected to a tube (7) stand, which is connected to the second with a coiled pipe (10) and stirrer (11) provided container (8) leads, devices are made that by the Coiled pipe of the second container. (8) Alternating cooling or heating fluid sent can be, while in which the two containers connecting pipes a Pump (9) is switched on.
