Abstract

Appts. has a sieve -plate column with condenser and reboiler. Auxiliary vessels allow solids to be extracted, liquids to be fed to the column for liquid-liquid extraction and distillations to be carried out and liquid fractions collected. Used for pilot-scale investigational work, partic. in the field of natural products, plant extracts etc. A series of extraction and distillation processes may be carried out on for instance, a batch of material, without the need to assemble different combinations of equipment.

UNIVERSELL VERWENDBARE EXTRAKTIONS- UND DE STILLATI ONSANLAGE pie Isolierung von Pflanzeninhaltsstoffen und Syntheseprodukten ist oft mit schwierigen Extraktionsprozessen verbunden. Bisher wurden dazu verschiedene Apparaturen benutzt, je nachdem, ob es sich um eine Fest - Flüssig- oder um eine Flüssig - Flüssig -Extraktion handelte.UNIVERSALLY USABLE EXTRACTION AND DE STILLATION PLANT pie Isolation of phytonutrients and synthetic products is often difficult with Extraction processes connected. So far, various devices have been used for this purpose, depending on whether it is a solid - liquid or a liquid - liquid extraction acted.

Gegenstand der vorliegenden Erfindung ist deshalb die Entwicklung einer Extraktionsanlage, die ohne technische Änderungen sowohl die Fest - Flüssig als auch die Flüssig - Flüssig - Extraktion gestattet. Ausserdem kann die Apparatur vorteilhafterweise zur fraktionierten Destillation von Gemischen verschiedener Flüssigkeiten eingesetzt werden.The subject of the present invention is therefore the development an extraction plant, which without technical changes both the solid - liquid as well as liquid-liquid extraction are permitted. In addition, the apparatus advantageously for the fractional distillation of mixtures of different liquids can be used.

Die konstruktiven Einzelheiten der Erfindung zeigt die beigefügte Skizze der Anlage. Sie besteht aus folgenden Einheiten die - hier für den Pilot-Masstab beschrieben - in der Skizze mit entsprechenden Zahlen bezeichnet sind: 1.) Uinlaufverdampfer mit 50 1 Inhalt 2.) Siebbodenkolonne mit Pulsator (7) 3.) Feststoffbehälter mit 140 1 Inhalt, zylinderförmig, die Ablasshähne mit Glasfritten versehen 4.) Wechsel-Vorlage mit 2 Kolben mit je 10 1 Inhalt zur Abnahme verschiedener Fraktionen 5.) Nivelliereinrichtung zur Regulation der Flüssigkeitshöhe und Höhe der jeweiligen Phasen in der Siebbodenkolonne 6.) Zwei Vorlagen, je 20 1 Inhalt, für Flüssigkeiten verschiedener Dichte und Mischbarkeit 8.) Kondensator Die vielfachen Verwendungsmöglichkeiten für die in der Abbildung beschriebene Anlage sollen die folgenden Beispiele zeigen.The structural details of the invention are shown in the attached Sketch of the plant. It consists of the following units - here for the pilot scale described - marked with corresponding numbers in the sketch: 1.) Inlet evaporator with 50 l capacity 2.) Sieve tray column with pulsator (7) 3.) Solids container with 140 l capacity, cylindrical, the drain cocks provided with glass frits 4.) Exchange template with 2 flasks with 10 1 content each for taking different fractions 5.) Leveling device to regulate the liquid level and the level of the respective phases in the sieve tray column 6.) Two templates, each containing 20 liters, for liquids of different densities and miscibility 8.) Capacitor The multiple uses for the in the figure The following examples are intended to show the system described.

A) FEST - FLÜSSIG - EXTiZAKTI0N Der Feststoffbehälter (3) wird mit ca. 20 kg des zu extrahierenden Materials, z. B. Pflanzenmaterial wie zerkleinerten Blättern, Rinden oder Wurzeln, beschickt. Mit Hilfe des Umlaufverdampfers (1) wird das Lösungsmittel über die Kolonne (2) und den Kondensator (8) von unten her in den Feststoffbehälter (3) gebracht und solange aufsteigen und auf das zu extrahierende Material einwirken gelassen, bis es die Höhe des seitlichen Abflusses erreicht und in den Destillationskolben des Umlaufverdampfers zurückfliesst. Dieser Vorgang wird kontinuierlich solange durchgeführt, bis eine erschöpfende Extraktion erreicht ist. Anschliessend wird der Extrakt konzentriert, indem das Lösungsmittel soweit über Kolonne und Kondensator abdestilliert wird, dass der Rückstand noch flüssig ist und abgelassen werden kann. Die Anlage erlaubt auch eine Destillation unter vermindertem Druck.A) SOLID - LIQUID - EXTiZAKTI0N The solids container (3) is with approx. 20 kg of the material to be extracted, e.g. B. Plant material such as crushed Leaves, bark or roots, loaded. With the help of the circulation evaporator (1) the solvent through the column (2) and the condenser (8) from below in brought the solids container (3) and as long as rise and on the to be extracted Allow the material to act until it reaches the level of the side drain and flows back into the distillation flask of the circulation evaporator. This process will carried out continuously until an exhaustive extraction achieved is. The extract is then concentrated by adding the solvent so far It is distilled off via the column and condenser so that the residue is still liquid is and can be drained. The plant also allows a distillation below reduced pressure.

B) FLÜSSIG - FLÜSSIG - EXTRAKTION Die zu extrahierende Lösung von Pflanzeninhaltsstoffen oder Syntheseprodukten wird aus einer Vorlage (6) mit Hilfe einer Chemiepumpe in die Siebbodenkolonne (2) gepumpt. Anschliessend wird das zur Extraktion verwendete Lösungsmittel aus der anderen Vorlage (6) ebenfalls in die Kolonne befördert. Durch Einschalten des Pulsators werden die beiden Flüssigkeiten innig vermischt, so dass das zu extrahierende Produkt in das zweite Lösungsmittel übergeht. Anschliessend werden die Phasen getrennt und das Lösungsmittel mit Hilfe des Umlaufverdampfers - eventuell im Vakuum - vom Rückstand abdestilliert. Der Extrakt wird abgelassen und weiter verarbeitet.B) LIQUID - LIQUID - EXTRACTION The solution to be extracted from Plant ingredients or synthetic products are made from a template (6) with the help a chemical pump is pumped into the sieve tray column (2). This then becomes the Extraction used solvent from the other template (6) also into the Conveyed column. By switching on the pulsator, the two liquids become intimately mixed so that the product to be extracted is in the second solvent transforms. The phases are then separated and the solvent is removed with the aid of the circulation evaporator - possibly in vacuo - distilled off from the residue. The extract is drained and processed further.

C) FRAKTIONIERTE DESTILLATION Nach bekannten Methoden können mit der beschriebenen Apparatur Gemische aus mehreren Flüssigkeiten, die sich in ihrem Siedepunkt unterscheiden, über die Siebbodenkolonne in einzelne Fraktionen zerlegt werden.C) FRACTIONAL DISTILLATION According to known methods, the described apparatus Mixtures of several liquids, which differ in their boiling point are divided into individual fractions via the sieve tray column.
