Description

Verfahren zur Herstellung von Emulsionen Die Erfindung betrifft ein Verfahren zur Blearbeitung von Flüssigkeiten, insbesondere zur Herstellung von Emulsionen unter Behandlung mit mechanischen Schwingungen.Process for the production of emulsions The invention relates to a Process for the processing of liquids, in particular for the production of emulsions under treatment with mechanical vibrations.

Es ist bereits bekannt, Flüssigkeiten unter der Einwirkung mechanischer Schwingungen sowohl oberhalb wie auch unterhalb der Hörfrequenz zu bearbeiten. B!esonders oft wird von diesem Verfahren beim Hgerstellen von Emulsionen mit Vorteil Gebrauch gemacht. It is already known that liquids under the action of mechanical Process vibrations both above and below the listening frequency. Particularly This method is often used to advantage in the preparation of emulsions made.

Gemäß der Erfindung werden die bekannten Verfahren dadurch wesentlich verbessert, daß außer einer Behandlung der Flüssigkeiten mit mechanischen Schwingungen über Hörfrequenz auch eine Behandlung mit Schwingungen in einem niedrigeren Frequenzbereich (bis etwa 100 Hz) erfolgt. Die Bearbeitung mit diesen Gruppen von Frequenzen kann gleichzeitig, gegebenenfalls aber auch nacheinander vorgenommen werden. Als Schwingungen niedererer Frequenz kommen vorwiegend solche U1 einem Bereich von 5 bis 100 Hz in Betracht. Der wesentliche Vorteil des erfindungsgemäßen Verfahrens ist darin zu sehen, daß bei dieser kombinierten Behandlung eine wesentlich größere Freizügigkeit in der Wahl der prozentualen Anteile von beispielsweise zu emulgierenden Komponenten erreicht wird. According to the invention, this makes the known methods essential improves that apart from a treatment of the liquids with mechanical vibrations a treatment with vibrations in a lower frequency range via hearing frequency (up to about 100 Hz). Editing with these groups of frequencies can be done at the same time, but optionally also one after the other. As vibrations The lower frequency mainly comes from U1 in a range from 5 to 100 Hz Consideration. The main advantage of the method according to the invention is therein too see that with this combined treatment a much greater freedom of movement in the choice of the percentage of components to be emulsified, for example is achieved.

Da die verschiedenen Komponenten bei verschiedenen Frequenzen ihre Behandlungsoptima haben, können mit den Verfahren nach der Erfindung auch solche Flüssigkeiten miteinander zur Emulgierung gebracht werden, deren Optima bei stark unterschiedlichen Frequenzen liegen.Since the different components are at different frequencies their Have treatment options, can with the method according to the invention such liquids are also brought to emulsification with one another, their optima lie at very different frequencies.

In vielen Fällen kann es noch eine zuzätzliche Verbesserung bringen, wenn die zu bearbeitenden Flüssigkeiten außerdem noch unter den Einfluß eines Ruh:rwerkes oder eines durch eine Pumpe aufgedrückten Umlaufes gestellt werden, wodurch einerseits noch eine bessere Durchmischung, dererseits aber zuverlässig erreicht wird, daß alle Teile in gleicher Weise unter den Einfluß der Schwingungen kommen. Das neue Verfahren bietet nicht nur bei der Herstellung von Emulsionen, sondern auch bei anderweitigen Behandlungen von Flüssigkeiten Vorteile. In many cases it can bring an additional improvement if the liquids to be processed are also under the influence of a movement or a circulation forced on by a pump, whereby on the one hand even better mixing, on the other hand it is reliably achieved that all Parts come under the influence of vibrations in the same way. The new procedure offers not only in the production of emulsions, but also in other areas Treatments Of Liquids Benefits.
