Description

Verfahren zum Behandeln von Tabak und anderem Gut in einem elektrischen Hochfrequenzfeld Sowohl für das gleichmäßige Befeuchten von Tabak als auch für das Nachtrocknen gefeuchteter Tabake hat mau bereits vorgeschlagen, das Tabakgut einem elektrischen Wechselfeld auszusetzen, dessen Frequenz einer Wellenlänge von etwa 5 bis 95 m entspricht. Im ersteren Fall sollen durch die Frequenzen Eigenschwingungen der Wasserteilchen im Tabak hervorgerufen werden, um dadurch zu erreichen, daß sich diese Feuchtig'keitsteilchen, die dem Tabak vorher durch Feuchtigkeit od. dgl. mitgeteilt wurden, schnell und gleichmäßig verteilen. Im letzteren Fall soll durch das hochfrequente Feld ein möglichst schnelles Abdampfen des Wassers erzielt werden. In beiden Fällen sind an den Grenzschichten zwischen Feuchtigkeit und Tabak starke Spannungsunterschiede vorhanden, deren Überwindung beachtliche Energien zur Bildung des Wechselfeldes erforderlich macht.Process for treating tobacco and other goods in an electrical one High frequency field Both for evenly moistening tobacco and for Post-drying of moistened tobacco has already suggested that the tobacco product be one to expose an alternating electric field, the frequency of which is about a wavelength 5 to 95 m. In the first case the frequencies are supposed to result in natural oscillations of the water particles in the tobacco are caused in order to achieve that these Feuchtig'keitteilechen previously communicated to the tobacco through moisture or the like distribute quickly and evenly. In the latter case, through the high frequency Field the fastest possible evaporation of the water can be achieved. In both cases there are strong differences in tension at the boundary layers between moisture and tobacco present, the overcoming of which considerable energies for the formation of the alternating field makes necessary.

Es,wurde nun gefunden, daß diese Energien sich erheblich verringern lassen, wenn die Behandlung des Tabaks im elektrischen Feld in Verbindung mit einer Behandlung im Vakuum erfolgt. Bekanntlich wird der Tabak sowohl beim Trocknen als auch beim Feuchten im Vakuum derart aufgeschlossen, daß er an Volumen zunimmt und für seine jeweilige überraschend gleichmäßige Behandlung nur geringer Temperaturen bedarf. Wenn derartiger im Vakuum vorbehandelter Tabakeinern Hochfrequenzfeld ausgesetzt wird, sind verhältnismäßig geringe Energien notwendig, um die Gleichmäßigkeit der Befeuchtung bzw. eine einwandfreie Trocknung des Tabaks in kurzer Zeit durchzuführen. Es ist zweckmäßig, das Feld in konditionierten Räumen zu bilden, in welchen ein Gleichgewichtszustand zwischen der Tabak- und Luftfeuchtigkeit vorhanden ist, um die Oberflächenspannung des Tabal@s ,beim A-usschleusen aus dem Vakuumkessel möglichst gering zu halten.It has now been found that these energies decrease considerably let when treating the tobacco in an electric field in conjunction with a Treatment takes place in a vacuum. As is well known, the tobacco is both dry and opened in such a way, even when wet in a vacuum, that it increases in volume and for its surprisingly uniform treatment of only low temperatures requirement. When such vacuum pretreated tobacco is exposed to a radio frequency field relatively low energies are necessary to ensure the evenness of the To carry out moistening or perfect drying of the tobacco in a short time. It is convenient that To form field in conditioned spaces, in which there is a state of equilibrium between tobacco and air humidity is about the surface tension of the Tabal @ s when it is discharged from the vacuum vessel to be kept as low as possible.
