    (54) CnOCQB INCREASED VOLUME OF TOBACCO
    The invention relates to the production of tobacco products, preferably cigarettes, to a technique for increasing the volume of tobacco. An increase in tobacco volume is required to compensate for the loss in weight during the drying process, to improve the smoking performance of individual tobacco components, in particular tobacco stems, and also to increase the cadre's full capacity of tobacco, so that less tobacco is needed to produce a tobacco product. amount of tobacco. Such a cigarette should be tight and at the same time release less tar and nicotine compared to a standard tobacco product made from tobacco with a non-increased volume. Closest to the invention is a known method for increasing the volume of taOaca, which involves soaking it with water, followed by freezing and drying in vacuum. The disadvantage of this method is its limited suitability for industrial implementation due to the duration of the process and its high cost, in particular at the drying stage. In addition, uneven support is created in tobacco for its swollen structure, which is the object of sedimentation, and water-soluble components are also washed out or redistributed. The aim of the invention is to accelerate the process of increasing the volume of tobacco. This is achieved by the fact that in the proposed method of increasing the volume of tobacco before soaking, the tobacco is evacuated, while the process of soaking itself is carried out at a pressure of 360,760 mm Hg. and a temperature of 0-80 ° C by spraying water for 230 minutes to a moisture content of 100-400 hours by weight to 100 hours, tobacco, and drying of tobacco is carried out at 120-320 seconds for 0.5 to 12 seconds. The method is carried out in the following manner. tobacco is subjected to vacuuming, for which it is placed, for example, in the form of chips in a vessel in which a vacuum is created at a pressure of 380-760 mm Hg. at 16-27 0, air is removed from the tobacco. Then the tobacco is impregnated with water; in addition, the impregnation process is also carried out at a pressure of 360-760 mm Hg. at least for 2-30 minutes, preferably with a stream of water, to a moisture content of 100-400 hours by weight to 100 hours of tobacco. Further, the water-impregnated filler is frozen by cooling to a temperature low enough to ensure complete freezing of moisture at a temperature of from 60 to wasps, preferably from -30 to -10 ° C, while maintaining a vacuum in the system and keeping it for 3-120 minutes, mostly 10-30 min. Then, the frozen, moisture-containing tobacco is dried, for which it is rapidly heated by direct contact with steam or a mixture of steam and hot gas at 120–320 ° C for 0.5–12 s. Drying is carried out in a vacuum in a drying chamber, in a tower, and also in a cyclone dryer, ensuring adequate contact of the gas with the particles. For carrying out the process, it is possible to process either completely dried tobacco leaves, tobacco in the form of shavings or chips, in particular in the form usually used as a cigarette filler, or individual parts of tobacco, for example, tab. stems. Tobacco in powder form can have a particle size of 10-50 mesh, preferably at least 30 mesh. Usually, processed tobacco contains about 8-25 wt.% Moisture. A and Ki 1. p. 283.5 g of cut light tobacco in the form of commercial cigarette filler is placed in a 454 g vacuum vessel having vacuum and outlet openings and pressure gauges, and a vacuum of 635 mm Hg is used.

    52.7 48.8:, 7.2 Tobacco is impregnated at CS with 507 g of cold water by vacuum suction to a content of 66% by weight of moisture in tobacco for 5 minutes. Each distribution of water is ensured by rotating the entire length of the vacuum vessel during the wetting process. Then the vacuum vessel is placed in a bath filled with a mixture of acetone and dry ice, and the temperature of the tobacco mixture is adjusted to. The vacuum is adjusted to 762 mm Hg. The mixture was allowed to equilibrate for 1 hour, after which the vacuum was released. The final material from the vessel is discharged and passed through a cyclone dryer at 218 ° C and maintaining a 100% steam atmosphere for 8 s. Subjected to an increase in the volume of tobacco is again brought to its moisture content from 6.1 to 12%. The final product has a filling capacity (cylinder volume) of 53 g as compared with a control value of 38 g. Examples 2-5. Four samples of 283.5 g of each light cut tobacco are treated individually as follows. Each sample is placed in a vacuum vessel as described in Example 1. The vacuum is adjusted to 635 mm Hg, the samples are soaked in cold water as described in Example. 1, respectively, until the moisture content is 50, 67, 75 and 80% by vacuum suction, in each case the vacuum vessel is placed in a bath cooled by a mixture of ice and sodium chloride to -27 ° C. Vacuum in each experiment support 762 mm Hg. After 1 hour of equilibration, the vacuum is turned off and the sample is passed through a cyclone dryer at 218 ° C in a 100% steam atmosphere. The residence time in the dryer varies depending on the moisture content. Qualitative indicators of tobacco samples are given in table. 1. Table 1
    The data table. Figure 1 shows that with increasing moisture content, filling capacity increases if other expansion parameters remain unchanged. The analyzed loss of components soluble in hot water is small, and such loss may result from chemical changes during expansion due to leaching of the dissolved components.
    Example 6. Two series of samples of 9080 g each impregnated in a spherical vacuum vessel. In the first series, 762 mm Hg is maintained. and cold water is introduced into the vessel to a moisture content of 30-80%, in which the swollen filler structure is deposited due to the formation of ice. This is achieved by passing a cooled solution of ethylene glycogenic samples Humidity after impregnation,% 30 50 67 75 80 Humidity after 9.5 11.5 7.5 7.5 drying,% Filling capacity, g 49 42 70 75 82 Stay time, s 4 4 8 8 12 Filling capacity after re-wetting to 12%, CMVlO g 39 40 52 58 62
    The data table. 2 show that the re-filling capacity of tobacco, the swollen structure of which is stabilized by the formation of ice before removing the vacuum and settling the structure when heated, is higher than the re-filling capacity of unfrozen material, this indicates the need for a freezing step to achieve maximum expansion in this process.

    After a period of equilibration for 2 hours at a vacuum of 711 mm Hg. and a temperature of 2, the vacuum is gradually dropped. The samples are then passed through a cyclone dryer at.
    In the second series, the experiment was carried out in the same way as in the first, but the freezing stage was not performed, and the balance was established at 21 ,.
