Definitions

  • the invention relates to a filter cigarette with a tobacco filter and a method of manufacturing such a filter cigarette.
  • the object of the invention is therefore to make a filter out of tobacco for smoking products which does not have the disadvantages mentioned in the state of the art.
  • a filter cigarette with a tobacco filter comprising the following features: a tobacco strand enclosed by a cigarette paper; wherein the tobacco mixture of the tobacco strand contains a proportion of 15 to 30% of cut medium cut rolled stem; and the smoke condensate yield of the tobacco strand is between 15 and 19 mg condensate for a strand length of 63 mm and a smoking length of 55 mm; with a filter manufactured from aromatic tobaccos with a drawing resistance between 50 and 100 mmWC at a length of 21 mm; and with a filter ventilation zone running in circumferential direction; wherein the degree of filter ventilation is 30 to 70% and which is characterized in that the filter tobacco is manufactured without using medium cut rolled stem and without reconstituted tobacco with a width of cut of 0.3 to 0.6 mm; and that the filter has a tobacco packing density of 350 to 450 g/cm 3 .
  • the achievement thus consists of using aromatic tobacco for the tobacco filter, as the smoke taste is very strongly characterized by the filter material. It has been shown that by a special treatment of the selected tobacco the advantageous taste-improving effect can once more be clearly increased. To this end, the selected tobacco material or parts thereof are subjected to a thermal treatment explained hereafter.
  • the tobacco is raised to a tobacco temperature between 60° C. and 150° C., preferably 80° C. to 130° C., for a period of between 1 minute and a maximum of 15 minutes. During this time, it is subjected to a relative humidity of 40 to 80%, preferably 50 to 70%. This leads to a significantly improved aroma transfer from the filter tobacco into the smoke passed through.
  • the effect can be selectively influenced and increased by adding suitable casing materials. When a somewhat finer width of cut of 0.3 to 0.6 mm is selected which can still be processed on standard machines (0.7 to 1.0 mm is usual for strand cut tobacco), filter-typical drawing resistances of 50 to 100 mmWC can then be achieved and the retention capacity clearly increased.
  • drawing resistances are generally also called “normal” or usual drawing resistances.
  • the retention capacity nevertheless still clearly lower compared with usual filter materials for which cellulose acetate reaches approximately 30 to 60%, whereas the range for tobacco filters is only approximately 25 to 35%, can be compensated for by using strand mixtures with clearly reduced condensate potential.
  • tobacco strands are used which, when smoked with a smoking machine, yield approximately 16 mg condensate instead of usually approximately 23 mg condensate.
  • such mixtures which can be manufactured e.g. with a high proportion of cut rolled stem or cheap tobaccos, are not particularly good in terms of taste, the smoke taste surprisingly acquires a pleasant aroma when passing through the tobacco filter.
