Definitions

  • the invention relates to a filter cigarette with a tobacco filter and a method of manufacturing such a filter cigarette.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • strand 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.
