Description
. Die zu entfettenden Substanzen werden in ein geeignetes GefÜfs gebracht, welches hermetisch verschlossen werden kann. Vermittelst einer Luftpumpe wird darauf das Gefiifs möglichst luftleer gemacht. Sobald das gewünschte Vacuum erreicht ist, wird das Lösungsmittel, z, B. Benzin, auf geeignete Weise in das Gefäfs gebracht. Die luftleer gemachten Substanzen, z. B. Knochen, saugen sich voll von dem Lösungsmittel. Sobald die gewünschte Menge des Lösungsmittels eingelaufen ist, setzt man die Luftpumpe wieder in Gang. Durch das erzeugte Vacuum wird der Siedepunkt des Lösungsmittels verringert und der ganze Raum des Gefafses füllt sich mit Dämpfen desselben. Nachdem die Dämpfe einige Zeit: gewirkt halten, hebt man durch Zulassen von Luft das Vacuum wieder auf, wodurch das Lösungsmittel aus dem dampfförmigen in den flüssigen Zustand übergeführt wird und hierbei das Fett auflöst. !Die Fettlösung sammelt sich im unteren Räume des Gefäfses an. Nachdem dies geschehen, wird das Lösungsmittel unter Anwendung des Vacuums wieder verdampft.. The substances to be degreased are placed in a suitable vessel, which is hermetically sealed can be closed. With the help of an air pump, the vessel is then as much as possible evacuated. As soon as the desired vacuum is reached, the solvent, e.g. gasoline, brought into the vessel in a suitable manner. The evacuated substances z. B. bones, soak up full of the solvent. As soon as the desired amount of the If the solvent has run in, the air pump is started again. Through the generated Vacuum will reduce the boiling point of the solvent and the whole space of the The vessel fills with its vapors. After the fumes have worked for some time: the vacuum is released by admitting air, which removes the solvent from the vapor is converted into the liquid state and thereby dissolves the fat. !The Fat solution accumulates in the lower space of the vessel. After this is done, the solvent is evaporated again using the vacuum.
Die durch die Luftpumpe abgesaugten Dämpfe werden durch eine Kühlvorrichtung condensirt.The vapors extracted by the air pump are condensed by a cooling device.
Die Anwendung des Verfahrens ist dann von besonderer Wichtigkeit, wenn entweder die zu entsprechende Substanz selbst oder das Fett unter jiem Einflüsse von Wärme leidet.The application of the procedure is of particular importance if either the to corresponding substance itself or the fat suffers under the influence of heat.
