KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft einen Extraktions- und Destillierapparat, bei welchem in dem Eindampfgefäß unterhalb der Heizschlange, welche das Lösungsmittel an derThe present invention relates to an extraction and distillation apparatus in which in the evaporation vessel below the heating coil, which carries the solvent to the
5 Oberfläche der in dem Eindampfgefäß befindlichen Flüssigkeit verdampft, eine Kühlschlange angeordnet ist. Diese hat den Zweck, die Masse der Flüssigkeit kühl zu halten, so daß die in Lösung gehaltene Substanz nicht durch die zur Verdampfung erforderliche Hitze verschlechtert wird.5 Surface of the liquid in the evaporation vessel evaporates, a cooling coil is arranged. The purpose of this is to keep the bulk of the liquid cool, so that the substance kept in solution is not deteriorated by the heat required for evaporation.
Auf der Zeichnung ist ein senkrechter Schnitt des Apparates dargestellt.The drawing shows a vertical section of the apparatus.
Die Vorrichtung besteht aus dem Auslaügegefäß A, das durch das Rohr a, a1 mit einem Eindampf- oder Destilliergefäß B . verbunden ist. Von dem Rohr al zweigt ein Rohr a2 nach oben ab und mündet oberhalb des Rohres a1 in den Apparat B ein. Rohr α1 und Zweigrohr α2 sind mit Hähnen a3 bezw. a4 versehen. In dem Eindampfgefäß B sind oben und unten je eine Heizschlange C bezw. C1 angeordnet, die mit Dampfröhren c, c1 in Verbindung stehen. Der Dampfzufluß von diesen Röhren zu den Heizschlangen wird durch Hähne c2, cs bezw. c4, c5 geregelt. Das Gefäß B ist mit einem Rückflußkühler E versehen. Unter der Heizschlange C ist eine kontinuierlich gespeiste Kühlschlange G an geordnet.The device consists of the leaching vessel A, which passes through the pipe a, a 1 with an evaporation or distillation vessel B. connected is. From the tube a l, a pipe branches off a 2 upwards and opens into the apparatus B above the pipe a 1. Tube α 1 and branch tube α 2 are respectively with taps a 3. a 4 provided. In the evaporation vessel B are respectively a heating coil C and below. C 1 arranged, which are connected to steam tubes c, c 1 . The steam flow from these tubes to the heating coils is through taps c 2 , c s respectively. c 4 , c 5 regulated. The vessel B is provided with a reflux condenser E. Under the heating coil C , a continuously fed cooling coil G is arranged.
Die Arbeitsweise ist folgende:
Nachdem die zu extrahierenden Kräuter oder dergl. in das Auslaugegefäß A gebracht
sind und eine alkoholische Flüssigkeit dazu gegeben ist, wird der Hahn α3 geöffnet, so
daß die Flüssigkeit aus dem Extraktor A. in das Eindampfgefäß B fließt und der Flüssigkeitsspiegel
in beiden Apparaten gleich ist. Dann wird durch Anstellen der Hähne c4
und c5 Dampf in die Heizschlange C geleitet,
währenddessen sind die Hähne c2, c3 geschlossen. In die Kühlschlange G leitet man
die Kühlflüssigkeit ein. Das Lösemittel der an der Oberfläche befindlichen Masse destilliert
dann ab, gelängt in den Kühler E, von wo es verflüssigt wieder nach A geleitet wird,
während die schwerere, vom Lösemittel befreite Lauge zum Kühlrohr G hinabsinkt und
neue, aus Lösemittel und Lauge bestehende Flüssigkeit nach oben treten läßt. Falls ein
höherer Konzentrationsgrad des Extraktes gewünscht werden sollte, beheizt man nachher
noch die Heizschlange C1.The way it works is as follows:
After the herbs to be extracted or the like. Are brought into the leaching vessel A and an alcoholic liquid is added, the valve α 3 is opened so that the liquid flows from the extractor A into the evaporation vessel B and the liquid level in both devices is the same is. Then, by turning on the taps c 4 and c 5, steam is passed into the heating coil C , during which the taps c 2 , c 3 are closed. The cooling liquid is introduced into the cooling coil G. The solvent in the mass on the surface then distills off, gets into the cooler E, from where it is liquefied and fed back to A , while the heavier, solvent-free liquor sinks down to the cooling pipe G and new liquid consisting of solvent and liquor follows lets step up. If a higher degree of concentration of the extract is required, heating coil C 1 is then heated.
Der Extrakt wird durch Rohr b5 abgezogen. The extract is drawn off through tube b 5 .
