Definitions

• the invention relates to a filter cigarette with a tobacco filter and a method for producing such a filter cigarette.
• tobacco can also be used as a filter material for smoking articles.
• tobacco Compared to other common filter materials such as cellulose (paper) or cellulose acetate, tobacco has a significantly lower retention rate for condensate and nicotine with the same draw resistance.
• tensile resistances such as are customary in cellulose filters or filters made of cellulose acetate, when using conventional tobacco mixtures as used for cigarettes, i.e. which are between 50 and 100 mm S for a filter length of 21 mm, for example.
• 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 one is used to solve this task
• Tobacco filter with the following features: a tobacco rod surrounded by cigarette paper; where the tobacco blend of the tobacco rod has a share of 15 to 30% cut medium rib contains; 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 degree of filter ventilation being 30 to 70% and which 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.
• the solution therefore consists in using aromatic tobacco for the tobacco filter, since the smoke taste is very strongly influenced by the filter material. It has been shown that the advantageous taste-improving effect can be significantly increased again by special treatment of the selected tobacco.
• the selected tobacco material or parts thereof are subjected to a thermal treatment explained below.
• the tobacco is brought 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 the tobacco preparation process. During this time it is exposed to a relative humidity of 40 to 80%, preferably 50 to 70%. This leads to a significantly improved aroma transition from the filter tobacco into the smoke passed through.
• the effect can be specifically influenced and increased by adding suitable casing materials. If a slightly finer cutting width of 0.3 to 0.6 mm is selected, which can still be processed on standard machines (usual for strand-cut tobacco is 0.7 to 1.0 mm), then filter-typical tensile resistances of 50 to 100 can be achieved Achieve mmWS and significantly increase the retention rate.
• Such tensile resistances are generally called "normal" or usual train resistance.
• the still significantly lower retention performance compared to conventional filter materials, for which cellulose acetate reaches approx. 30 to 60%, while tobacco filters are only around 25 to 35%, can be compensated for by using strand mixtures with a significantly reduced condensate potential.
• tobacco strands are used which, when smoked with a smoking machine, deliver approx. 16 mg of condensate instead of usually approx. 23 mg of condensate.
• such mixtures which can be produced, for example, with a high proportion of ribs or inexpensive tobacco, are not particularly good in taste, the smoke taste surprisingly obtains a pleasant aroma when it passes through the tobacco filter.
