Abstract
Description
Die Erfindung betrifft eine Filtercigarette mit einem Tabakfilter und ein Verfahren zur Herstellung einer derartigen Filtercigarette.The invention relates to a filter cigarette with a tobacco filter and a method of manufacturing such a filter cigarette.
Es ist seit langem bekannt, daß auch Tabak als Filtermaterial für Rauchartikel eingesetzt werden kann. Im Vergleich zu anderen gebräuchlichen Filtermaterialien wie Cellulose (Papier) oder Cellulose-Acetat hat Tabak jedoch bei gleichem Zugwiderstand eine deutlich geringere Retentionsleistung für Kondensat und Nikotin. Außerdem ist es nicht leicht, bei Verwendung von gebräuchlichen Tabakmischungen, wie sie für Cigaretten verwendet werden, Zugwiderstände zu erreichen, wie sie bei Cellulose-Filtern oder Filtern aus Cellulose-Acetat üblich sind, d.h. die bei einer Filterlänge von beispielsweise 21 mm zwischen 50 und 100 mmWS liegen.It has long been known that tobacco as a filter material for Smoking articles can be used. Compared to other common filter materials such as cellulose (paper) or However, tobacco has a cellulose acetate with the same draw resistance significantly lower retention rate for condensate and nicotine. Also, it is not easy to use common ones Tobacco blends as used for cigarettes To achieve tensile resistances, as in cellulose filters or Cellulose acetate filters are common, i.e. the one Filter length of, for example, 21 mm between 50 and 100 mmWS lie.
Zur Überwindung dieses Nachteils wurden bereits verschiedene Lösungsvorschläge gemacht, nämlich zum einen den Filterteil aus Rippentabak herzustellen. Dies bringt jedoch einen schlechten Geschmack mit sich. Zum anderen wurde vorgeschlagen, den Filterabschnitt aus expandiertem Tabak zu machen, was jedoch nur eine sehr geringe Retentionsleistung und damit eine ungenügende Filterwirkung ergab. Schließlich wurde auch sehr fein geschnittener Tabak als Filterelement vorgeschlagen; dieser läßt sich jedoch auf gebräuchlichen Maschinen nicht verarbeiten und würde damit zu hohen Filterkosten führen.Various solutions have already been proposed to overcome this disadvantage , namely to produce the filter part from rib tobacco on the one hand. However, this brings with it a bad taste. On the other hand, it was proposed to make the filter section from expanded tobacco, but this resulted in only a very low retention rate and therefore an insufficient filter effect. Finally, very finely cut tobacco was also proposed as a filter element; However, this cannot be processed on conventional machines and would therefore lead to high filter costs.
Die Aufgabe der Erfindung besteht also darin, einen Filter aus Tabak für Rauchartikel zu schaffen, der die beim Stand der Technik erwähnten Nachteile nicht besitzt.The object of the invention is therefore to provide a filter made of tobacco for smoking articles which does not have the disadvantages mentioned in the prior art.
Zur Lösung dieser Aufgabe dient eine Filtercigarette mit einem Tabakfilter mit folgenden Mekmalen: einem von einem Cigarettenpapier umgebenen Tabakstrang; wobei die Tabakmischung des Tabakstrangs einen Anteil von 15 bis 30% geschnittener Mittelrippe enthält; und die Rauchkondensatausbeute des Tabakstrangs zwischen 15 und 19 mg Kondensat bei einer Stranglänge von 63 mm und einer Abrauchlänge von 55 mm beträgt; mit einem aus aromatischen Tabaken hergestellten Filter mit einem Zugwiderstand zwischen 50 und 100 mmWS bei einer Länge von 21 mm; und mit einer in Umfangsrichtung verlaufenden Filter-Ventilationszone; wobei der Filter-Ventilationsgrad 30 bis 70% beträgt und die sich dadurch auszeichnet, daß der Filtertabak ohne Verwendung der Mittelrippe und ohne rekonstituierten Tabak mit einer Schnittbreite von 0,3 bis 0,6 mm hergestellt ist; und daß der Filter eine Tabakstopfdichte von 350 bis 450 g/cm3 hat.A filter cigarette with a tobacco filter with the following features serves to solve this task: a tobacco rod surrounded by a cigarette paper; wherein the tobacco blend of the tobacco rod contains 15 to 30% cut midrib; and the smoke condensate yield of the tobacco rod is between 15 and 19 mg of condensate with a rod length of 63 mm and a smoking length of 55 mm; with a filter made of aromatic tobacco with a tensile resistance between 50 and 100 mm water column with a length of 21 mm; and with a circumferential filter ventilation zone; the filter ventilation degree is 30 to 70% and is characterized in that the filter tobacco is produced without the use of the central rib and without reconstituted tobacco with a cutting width of 0.3 to 0.6 mm; and that the filter has a tobacco plug density of 350 to 450 g / cm 3 .
Die Lösung besteht somit darin, daß für den Tabakfilter aromatischer Tabak verwendet wird, da der Rauchgeschmack vom Filtermaterial sehr stark geprägt ist. Es hat sich gezeigt, daß durch eine besondere Behandlung des ausgewählten Tabaks der vorteilhafte geschmacksverbessernde Effekt nochmals deutlich erhöht werden kann. Dazu werden das ausgewählte Tabakmaterial oder Teile davon einer nachfolgend erläuterten thermischen Behandlung unterzogen.The solution is therefore that the tobacco filter is more aromatic Tobacco is used because of the smoke taste from the filter material is very strongly shaped. It has been shown that through a special treatment of the selected tobacco the beneficial taste-improving effect can be significantly increased again can. To do this, the selected tobacco material or parts thereof subjected to a thermal treatment explained below.
Der Tabak wird während das Tabakaufbereitungsprozesses für einen Zeitraum zwischen 1 Minute und maximal 15 Minuten auf eine Tabaktemperatur zwischen 60°C und 150°C, vorzugsweise 80°C bis 130°C gebracht. Während dieser Zeit wird er einer relativen Feuchte von 40 bis 80%, vorzugsweise 50 bis 70% ausgesetzt. Dies führt zu einem signifikant verbesserten Aroma-Übergang vom Filtertabak in den hindurchgeleiteten Rauch. Der Effekt kann durch Zusatz von geeigneten Casing-Materialien gezielt beeinflußt und gesteigert werden. Wenn eine etwas feinere Schnittbreite von 0,3 bis 0,6 mm gewählt wird, die noch auf Standardmaschinen verarbeitbar ist (üblich für Strang-Schnittabak ist 0,7 bis 1,0 mm), dann lassen sich damit filtertypische Zugwiderstände von 50 bis 100 mmWS erreichen und die Retentionsleistung deutlich erhöhen. Solche Zugwiderstände werden allgemein auch als "normale" oder übliche Zugwiderstände bezeichnet. Die trotzdem noch deutlich geringere Retentionsleistung im Vergleich zu üblichen Filtermaterialien, für die Cellulose-Acetat ca. 30 bis 60% erreicht, während Tabakfilter bei nur etwa 25 bis 35% liegen, läßt sich durch Einsatz von Strangmischungen mit deutlich reduziertem Kondensat-Potential kompensieren. Damit ist gemeint, daß Tabakstränge eingesetzt werden, die beim Abrauchen mit einer Rauchmaschine ca. 16 mg Kondensat anstelle von überlicherweise ca. 23 mg Kondensat liefern. Obwohl derartige Mischungen, die z.B. mit einem hohen Rippenanteil bzw. preisgünstigen Tabaken hergestellt werden können, geschmacklich nicht besonders gut sind, erhält der Rauchgeschmack beim Durchtritt durch den Tabakfilter überraschenderweise ein angenehmes Aroma.The tobacco is used during the tobacco preparation process Period between 1 minute and a maximum of 15 minutes at a time Tobacco temperature between 60 ° C and 150 ° C, preferably 80 ° C to Brought 130 ° C. During this time, he becomes a relative Exposed to moisture of 40 to 80%, preferably 50 to 70%. This leads to a significantly improved aroma transition from Filter tobacco into the smoke passing through. The effect can influenced by adding suitable casing materials and be increased. If a slightly finer cutting width of 0.3 to 0.6 mm is chosen, which is still on standard machines is processable (usual for strand cut tobacco is 0.7 to 1.0 mm), then filter-typical tensile resistances of 50 reach up to 100 mmWS and the retention performance clearly increase. Such tensile resistances are generally called "normal" or usual train resistance. The anyway retention performance compared to usual filter materials, for the cellulose acetate about 30 to 60% reached, while tobacco filters are only around 25 to 35%, can be clearly identified by using strand mixtures Compensate for reduced condensate potential. That means, that tobacco strands are used when smoking with a Smoking machine about 16 mg of condensate instead of usually Deliver approx. 23 mg of condensate. Although such mixtures that e.g. with a high proportion of ribs or inexpensive tobacco can be produced, taste not particularly good are, the smoky taste gets when passing through the Tobacco filters surprisingly have a pleasant aroma.
