KLASSEGREAT

Patentirt im Deutschen Reiche vom 9. Januar 1900 ab.Patented in the German Empire on January 9, 1900.

Das Verfahren benutzt eine besondere Eigenschaft des Nicotine, die darin besteht, dafs es trotz seines hohen Siedepunktes schon bei gewöhnlicher Temperatur eine grofse Flüchtigkeit besitzt, so dafs nicotinreicher Tabak bereits infolge einfacher Lagerung fortgesetzt nicotinärmer wird.The process uses a special property of nicotine, which consists in the fact that it is in spite of its high boiling point, it is very volatile even at ordinary temperature possesses, so that nicotine-rich tobacco continued as a result of simple storage becomes poorer in nicotine.

Das Verfahren kommt in folgender Weise zur Ausführung: Der Tabak wird zunächst in bekannter Weise mit einer schwach alkalischen Flüssigkeit besprengt und einige Zeit der Einwirkung derselben überlassen, dann nach dem Auflockern der Büschel —■ hier setzt die Erfindung ein — in einem cylindrischen Behälter an Rahmen so aufgehängt, dafs die Luft zu allen Blättern möglichst freien Zutritt hat. Man läfst nun so lange einen durch Zusatz von Dampf auf etwa 50° erwärmten und mit Feuchtigkeit gesättigten Luftstrom auf den Tabak einwirken, bis sich eine genügende Menge Nicotin verflüchtigt hat bezw. der Tabak nur noch den gewünschten Nicotingehalt besitzt.The process is carried out in the following way: The tobacco is first in as is known, sprinkled with a weakly alkaline liquid and left to act for some time left to the same, then after loosening up the tufts - this is where the invention comes in a - hung in a cylindrical container on a frame so that the air has free access to all sheets as possible. You can now run one for so long by adding heated by steam to about 50 ° and saturated with moisture air flow on the Act on tobacco until a sufficient amount of nicotine has evaporated or. the Tobacco only has the desired nicotine content.
