Description

Verfahren zur Beschleunigung des Gefriervorgangs bei mit gekühlten Salzlösungen arbeitenden-Gefrieranlagen Die vorliegende Erfindung betrifft ein Verfahren zur Beschleunigung des Gefriervorganges bei mit gekühlten Salzlösungen arbeitenden Gefrieranlagen. Bei solchen Gefrieranlagen tritt der Mangel auf, daß sich beim Umpumpen der Sole Schaumblasen im Gefrier- und Solebehälter bilden, die den Behälter zum Überlaufen bringen. Zudem wird der Wärmeübergang von den Verdampferschlangen zur Sole durch die Schaumbildung beeinträchtigt.Method to accelerate the freezing process with refrigerated Salt Solution Freezers The present invention relates to a method to accelerate the freezing process when working with chilled salt solutions Freezing systems. In such freezing systems, the defect occurs that when pumping over of the brine foam bubbles form in the freezer and brine container, which the container for Bring overflow. In addition, the heat transfer from the evaporator coils to the Brine impaired by foam formation.

" Diesem Mangel wird erfindungsgemäß dadurch abgeholfen, daß die Schaumbildung der Sole durch Zusatz spezifisch leichterer Flüssigkeiten, beispielsweise Öl, verhindert wird. An sich ist es bekannt, die Schaumbildung bei Gärungsprozessen durch Aufbringen von Ü1 oder Fett zu bekämpfen und ferner die Schaumfähigkeit von Flüssigkeiten durch Äther zu zerstören."According to the invention, this deficiency is remedied by the fact that the foam formation the brine is prevented by adding specifically lighter liquids, such as oil will. It is known per se, the foam formation during fermentation processes by application to fight against Ü1 or fat and also the foaming ability of liquids Destroy ether.

Bei Gefriereinrichtungen, die mit gekühlten Salzlösungen arbeiten, wird die Sole in einem Behälter durch eine Kältemaschine unter Benutzung von Verdampferschlangen abgekühlt und durch eine Pumpe in den Gefrierbehälter gefördert; hier nimmt die Sole die an den Fischen haftenden Schleimteilchen auf, welche die Schaumbildung sehr begünstigen. Wird die Sole nun in den Solebehälter zurückgeführt, dann bildet sich eine große Menge beständigen Schaumes, welcher den Wärmeübergang zwischen Verdampferschlange und Sole hindert und bewirkt, daß die Sole im Behälter überläuft. Der Schaum ist natürlich auch beim Gefrierender Fische schädlich, weil er die Wärmeübertragung hindert.For freezers that work with chilled saline solutions, the brine is in a container by a refrigeration machine using evaporator coils cooled and conveyed into the freezer container by a pump; here takes the Sole on the mucus particles adhering to the fish, which cause foam very favor. If the brine is now returned to the brine tank, it then forms a large amount of persistent foam, which the heat transfer between the evaporator coil and brine prevents and causes the brine in the container to overflow. The foam is Of course also harmful when freezing fish, because it does the heat transfer hinders.

Es wird nun der Sole zur Verhütung der Schaumbildung eine Flüssigkeit zugesetzt, welche spezifisch leichter als die Sole und geeignet ist, eine mehr oder weniger zusammenhängende Haut auf der Soleoberfläche zu bilden. Wird demgemäß verfahren, dann ist die Schaumbildung, d. h. die Bildung von Luftbläschen, welche von einer dünnen Flüssigkeitshaut umgeben sind, nicht möglich, weil die durch die Zusatzflüssigkeiten auf der Soleoberfläche erzeugte dünne Haut den Zutritt der Luft zur Sole hindert, so daß es zur Bildung von Schaumbläschen nicht kommen kann.The brine now becomes a liquid to prevent foaming added, which is specifically lighter than the brine and suitable, one more or to form less cohesive skin on the surface of the brine. If this is done accordingly, then foaming, i.e. H. the formation of air bubbles, which from a thin skin of liquid are not possible because of the additional liquids thin skin created on the brine surface prevents the air from reaching the brine, so that foam bubbles cannot form.

Geeignete Flüssigkeiten zur Verhinderung der Schaumbildung sind beispielsweise u. a. Öle, und zwar solche mineralischen als auch tierischen und pflanzlichen Ursprungs sowie Gemische dieser Öle miteinander oder mit anderen Flüssigkeiten. Das Hinzufügen solcher Flüssigkeiten zur Sole kann in einem der Behälter der Gefriereinrichtung oder auf dem Wege der Sole zu einem dieser Behälter erfolgen. Es .genügt schon eine Menge, die hinreicht, um eine im wesentlichen zusammenhängende Haut auf der Soleoberfläche in den Behältern zu bilden.Suitable liquids for preventing foam formation are, for example i.a. Oils, namely those of mineral as well as animal and vegetable origin as Mixtures of these oils with one another or with other liquids. The addition of such liquids to the brine can be done in one of the containers of the freezer or by way of the brine to one of these containers. One is enough Amount sufficient to create an essentially cohesive skin on the brine surface to form in the containers.
