Description

Verfahren zum Erzeugen von Klareis durch Einleiten eines ununterbrochenen Luftstromes Es ist bekannt, Klareis in der `reise herzustellen, daß ein ununterbrochener gleichföriniger Strom von Druckluft in das Gefrierwasser eingeleitet wird. Die Luft muß dabei weitgehend entfeuchtet werden, um zu verhindern, daß die in den Zellen befindlichen Einblaserohre zufrieren. Es ist deshalb üblich, die Einblaseluft zunächst auf einen höheren Druck zu verdichten, sie dann durch Kühlung zu entfeuchten und auf den Einblasedruck zu entspannen. Es ist auch bekannt, daß der Druck der in das Gefrierwasser einströmenden Luft dem wachsenden Wider-Stande durch die Eisbildung entsprechend ständig zunimmt. Es sind ferner Verfahren zur Erzeugung von Klareis bekannt, wobei abwechselnd Luft in das Gefrierwasser eingeblasen und Wasser aus der Gefrierzelle angesaugt wird. Durch diese Maßnahmen soll eine kräftige Bewegung des Gefrierwassers erzeugt werden.Method of producing clear ice by introducing a continuous Luftstromes It is known to produce clear ice in the `journey, that an uninterrupted uniform stream of compressed air is introduced into the freezing water. The air must be largely dehumidified to prevent that in the cells freeze over the injection pipes. It is therefore common to blow the air first to compress them to a higher pressure, then to dehumidify them by cooling and to relax on the injection pressure. It is also known that the pressure of the The air flowing in from the freezing water meets the increasing resistance caused by the formation of ice increases accordingly. There are also methods for producing clear ice known, with alternating air blown into the freezing water and water out the freezer cell is sucked in. These measures are intended to create a vigorous movement of the frozen water can be generated.

Es wurde nun gefunden, daß die bekannten Verfahren zur Klareiserzeugung durch Einleiten eines ununterbrochenen Stromes verdichteter, entfeuchteter und wieder entspannter Luft in das Gefrierwasser dadurch wesentlich verbessert werden, daß der Einblasedruck des Luftstromes sich zwischen dein statischen Druck des Gefrierwassers als unterer Grenze und ungefähr I kg; cm' als oberer Grenze während der Gefrierdauer abwechselnd ändert.It has now been found that the known processes for producing clear ice by introducing a continuous stream of compressed, dehumidified and again relaxed air in the freezing water are significantly improved in that the injection pressure of the air flow is between the static pressure of the freezing water as the lower limit and about 1 kg; cm 'as the upper limit during the freezing period alternately changes.

Gemäß weiterer Erfindung soll diese Änderung des Einblasedruckes stoßweise geschehen.According to a further invention, this change in the injection pressure should intermittently happen.

Ein geeignetes Mittel, dies zu erreichen, ist z. B. eine von der Hauptluftleitung vor der Unterbrechungsvorrichtung abzweigende Nebenleitung, in die ein Druckminderungsorgan eingeschaltet ist und die hinter der Unterbrechungsvorrichtung in die Hauptleitung mündet.A suitable means of achieving this is e.g. B. one of the main air line A secondary line branching off in front of the interruption device, into which a pressure reducing device is switched on and the one behind the interruption device in the main line flows out.

Durch die Druckwellen werden in dem Gefrierwasser plötzlich große Luftblasen erzeugt, die den Zelleninhalt kräftig durchwirbeln, eine bessere Entlüftung des Gefrierwassers und infolgedessen eine höhere Güte des erzeugten Eises zur Folge haben. Es ist hierbei ferner möglich, die einzublasende Luftmenge gegenüber der bei den bisher üblichen Verfahren erforderlichen zu verringern und damit den Arbeitsverbrauch des Luftverdichters herabzusetzen.The pressure waves suddenly become large in the freezing water Air bubbles created that swirl the cell contents vigorously, a better ventilation of the frozen water and consequently a higher quality of the ice produced to have. It is also possible here to compare the amount of air to be injected with to reduce the amount of work required in the previously customary procedures of the air compressor.
