Abstract

The invention relates to a tobacco filter for smoking products in which the tobacco material selected for the filter or parts thereof are subjected to a thermal treatment during the tobacco preparation process.

Description

509556 A7 B7 V. Description of the invention () 1 This invention relates to filter cigarettes. Tobacco has also been used as a filter material for cigarette articles for many years. Compared with other filter materials such as cellulose (paper) or cellulose acetate, tobacco obviously has lower holding power for cured products and nicotine when it has the same resistance to smoking. In addition, when using a conventional tobacco blend of cigarettes, it is not easy to achieve a smoking resistance that can be achieved with a filter having a filter length of 21111111 made of acetate fiber of 50mmWC. To overcome this disadvantage ', several solutions have been proposed, one of which is to make a filter part from cut rolled tobacco. However, this will cause the cigarette to taste bad. Another solution is to make the filter part with virulent tobacco ’but this will only result in low maintenance ability and poor filter effect. Finally, it has been proposed to use very finely cut tobacco as a filter element. However, this makes it impossible to operate on a general machine, which increases the cost of the crossing. The object of the present invention is to make a filter from tobacco making tobacco products without the conventional disadvantages mentioned above. Accordingly, the present invention provides a cigarette with a tobacco filter: a) a tobacco bundle wrapped with a cigarette paper; b) a filter made of aromatic tobacco with a smoking resistance between 50 and 100 mmWC; And c) a filter ventilation area in the circumferential direction; characterized by: d) the filter is made of cut high aromatic tobacco with a width of 0.3 to 0.6 mm, and does not use medium cut rolled stems and No reconstituted tobacco; e) the filter has a tobacco packing density of 350 to 450 g / cm3, and a filter smoking resistance of 50i100mmWC at a length of 21mm; The smoke concentration is 63mm when the length of the tobacco bundle is smoking and the paper size is in accordance with the national standard (CNS) A4 specification (21Q χ 297) ------

Description of the invention (, between 15 and I9mg when the length is 55mm; g) The tobacco mixture of tobacco bundles accounts for 15% to 50% of the mid-cut rolls; and (h) the filter ventilation is between 30% and 70%. The present invention includes flavored tobacco using a tobacco filter, because the taste of a cigarette is determined by the characteristics of the filter and mouth material. It has been shown that the taste of selected tobacco ' cigarettes can be improved by special treatment, and the selected tobacco material or portion thereof is treated with heat < In the process of preparing tobacco, the material should be between 6 degrees bricks and 50 degrees <:, preferably between 85 and 130. 〇 1 to 15 minutes. At the same time, it is added with a humidity of 40% to 80%, preferably 50% to 70%. The improved scent thus conducted to the cigarette filter is transmitted to the smoke passing through it. This effect can optionally be influenced and increased by the addition of a suitable housing material. When selecting a small, broad-skinned tobacco with 0.3 to 0.6 claws, it is still operated on a standard machine (usually the tobacco bundle is cut between 0.7 and 1.0 mm), so 50 to 10. The resistance to smoking of the basic filter Karma can be reached, and the maintenance power has increased significantly. This resistance to smoking is called "normal" or general resistance to smoking. The holding power is obviously lower than 30% to 60% that can be achieved by ordinary filter materials made of acetate fiber, however, the 25% to 35% holding power of tobacco filters can be achieved by using lower potential cured tobacco bundles. The mixture is compensated. This means that the tobacco bundle produces about 115 mg of cured material when smoked by a smoking machine, rather than about 23 mg of cured material. Although such a mixture made of, for example, a high proportion of cut rolls or cheap tobacco, does not taste particularly good, its smoke taste is surprisingly fragrant when passing through a tobacco filter.
