Abstract

The invention relates to a filter cigarette, comprising a tobacco filter. According to the invention, the tobacco which is selected for the filter, or parts thereof, have been subjected to thermal treatment during the tobacco preparation process.

Description

Description of the invention

The invention relates to a cigarette with a tobacco filter and a method of manufacturing such a cigarette with a filter. 2 It has long been known that tobacco can be used as a filter material for smoking products. However, compared to other filter materials used, such as cellulose (paper) or cellulose acetate, tobacco has a significantly lower ability to retain condensate and nicotine with the same draw resistance.

In addition, it is not easy when using ordinary mixtures of tobacco materials for the manufacture of cigarettes to achieve the drag resistance usual for filters made of cellulose or cellulose acetate, that is, with a filter length of 21 mm 70 from 50 to 100 mm of water column.

To overcome this shortcoming, various solutions have already been proposed, namely: firstly, making a filter from the veins of tobacco leaves. However, an unpleasant taste is felt at the same time. Secondly - the manufacture of a filter from loose tobacco, which, however, gives only a slight retention and therefore does not provide sufficient filtering action. Finally, very finely cut tobacco was proposed as filter material; 72, however, it cannot be processed by ordinary machines, and therefore the costs of manufacturing such a filter would be too high.

Therefore, the task of the invention is to develop a tobacco filter for smoking products, free from the indicated drawback of tobacco filters according to the state of the art.

A cigarette with a tobacco filter containing a tobacco rod wrapped in cigarette paper is used to solve this problem; and the mixture of tobacco materials of the tobacco rod contains from 15 to 3095 chopped veins of tobacco leaves; a tobacco rod has a condensate output of 15 to 19 mg with a length of the rod of bZmm and smoking of 55 mm; a filter made of aromatic varieties of tobacco, which has a resistance to tightening from 50 to 100 mm of water.st. with a length of 2 mm; a ventilation zone is located around the filter; the ventilation coefficient of the filter is from 30 to 7095, which is distinguished by the fact that the filter tobacco is made without the use of medium veins and without reduced tobacco with a cutting width from 0.3 to 0.bmm, and also by the fact that the filter has a packing density of of tobacco from 350 to 45Omg/cm?.

Thus, the solution to the problem is that aromatic tobacco is used for the tobacco filter, since the taste of the tobacco material stands out very strongly. It turned out that the taste of smoke can be significantly improved by special processing of selected tobacco. For this, the selected tobacco leaves or their parts are subjected to the heat treatment explained below. yes!

Heat treatment:

During the preparation process, tobacco is exposed to temperatures from 60°C to 150°C, preferably from 807°C to 130°C, within a time interval of 1 to 15 minutes. During this treatment, the relative humidity of the air is between 40 °I and 8095, preferably between 50 and 7095. This contributes to a significant improvement in the transfer of aromatic substances from the filter tobacco to the smoke passing through it. The effect can be enhanced by using suitable shell materials. In the case of using strips of a slightly smaller width - from 0.3 to 0.bmm, which can still be processed by standard machines (usually the width of cutting tobacco for the rod is from 0.7 to 1.00mm), typical values for filters can be achieved resistance to tightening from 50 to 100 mm of water. Art. « du and significantly higher retention capacity. Such values of tensile strength are called "normal" or -o ordinary. The holding capacity of the tobacco filter (only from 25 to 35965), which is still significantly lower compared to conventional filter materials (for cellulose acetate from 30 to 6090), can be compensated for by using a mixture of tobacco materials with significantly less condensate release for the manufacture of the rod . A tobacco rod can be used, from which, during smoking, about 16 mg of condensate is released instead of the usual values of about 2-3 mg of condensate. Although such mixtures, which can be c 15 made, for example, with a high content of veins or from cheap varieties of tobacco, do not have a particularly good taste, when passing through a tobacco filter, the smoke unexpectedly acquires a pleasant aroma. sh»

Claims (2)

(22) The formula of the invention from 50 1. A cigarette with a tobacco filter containing a tobacco rod wrapped in cigarette paper, and the mixture of tobacco materials of the tobacco rod contains from 15 to 30 to 90 chopped veins of tobacco leaves; the tobacco rod has a condensate output of 15 to 19 mg with a rod length of 63 mm and smoking of 55 mm, a filter made of aromatic tobacco varieties that has a resistance to drawing from 50 to 100 mm of water. Art. with a length of 21 mm, a ventilation zone located around the perimeter of the filter, and the ventilation coefficient of the filter (GF) is from 30 to 70 95, which differs in that the filter tobacco is made without using the medium veins and without regenerated tobacco with a cut width of 0.3 to 0.6 mm, as well as the fact that the filter has a density of tobacco filling from 350 to 450 g/cm 3. 2.
