    11 The invention relates to a method for preparing tobacco for the production of smoking articles, in particular to a method for increasing the volume of tobacco. There is a method of increasing the volume of tobacco, which includes obr§, treating with an impregnating substance under pressure, followed by a decrease in pressure to atmospheric and heat treatment lj. There is a method of increasing the volume of tobacco, which includes treatment with gaseous nitrogen and / or argon under pressure at 0-50 ° C, followed by pressure reduction to atmospheric pressure and heat treatment 2. However, the known methods are characterized by an insufficiently high quality of the tobacco produced. The purpose of the invention is to improve the quality of the processed tobacco. The goal is achieved by the method of increasing the volume of tobacco, which includes treatment with gaseous nitrogen and / or argon under pressure at 0-50 ° C, followed by pressure reduction to atmospheric pressure and heat treatment, treatment with gaseous nitrogen and / or argon is subjected to tobacco humidity 5 17%, and before the heat-treating tobacco, for 0.510 minutes, the water is impregnated with steam with a moisture content of 0.5-10 kg / m. Example. 200 g of cut Virginia tobacco is loaded into a cylindrical, open metal container on top, which is fed to an autoclave equipped with a heated casing. After closing, nitrogen or argon is introduced into the autoclave until reaching the final pressure indicated in the table, which also indicates the temperature (in the casing of the autoclave), which is then treated with nitrogen or argon. After treatment with nitrogen or. argon produces a decrease in pressure to atmospheric during the times indicated in the table. The autoclave is opened, the metal container is removed and the tobacco processed in this manner is fed to a glass substrate, on which it is distributed to form a canvas. Then, the tobacco is impregnated with saturated water vapor with the water content indicated in the table, supplied by means of a nozzle. The tobacco thus treated is dried by heat treatment with air heated to 200 ° C. 72 The ability to pack prepared tobacco thus examined in the following way. Samples are stored at 21 ° C and a relative humidity of 60% for 36 hours, after which, after reaching the equilibrium humidity, the packing capacity is determined using a Borgwald densimeter. The results thus obtained are compared with the results of the untreated sample and the achieved increase in packing capacity is determined in%. In addition, in%, the increase in the capacity for packing tobacco provided by a known method as compared to the untreated sample is also determined. In this case, the known method is carried out under the same conditions as the corresponding example of the proposed method, with the exception of the following differences: the tobacco is treated with a moisture content of 22.2% with nitrogen or argon and the heat treatment is carried out using microwaves. Then compare the results on the ability to stuffing tobacco, achieved by the proposed and known methods compared to the untreated sample. The table indicates how many percentage units the capacity for packing of prepared tobacco by the proposed method is equivalent to the capacity for packing tobacco prepared in a known manner (A, B, C, G. D, E, F, 3 are comparative examples confirming the significance of the proposed the moisture content of tobacco, the water content of saturated water vapor and the duration of impregnation.At this, example A is a comparative experience for examples Per and 36 example B - for example 4b, example B for examples 66 and 6b, example G - for example 76, example D - to example 16, example E - for example 1c, example W for example 565 and example 3 - for example 5c). Comparison of the results of examples A to D with the results of examples of Za, 36, 46, 66 and 76 suggests that when carrying out the proposed method outside the given moisture limits of tobacco and water content of the national (desired steam for the packing is not achieved, whereas the comparison The results of examples 16 and 56, with the results of comparative examples D and F, indicate a deterioration in the ability to pack tobacco at 31 times of P1x) feeding in less than 0.5 minutes, and a comparison of the results of examples 1c and 5c with the results of comparative measures E and 3 indicate that with brood impregnation for more than 10 minutes, the ability to pack tobacco is not significantly improved. The better packing capacity of the tobacco prepared by the proposed method is due to the fact that the more intensive cooling during blowing of the gas 74, observed in tobacco with a lower moisture content, leads to the inclusion of a larger amount of gas in the tobacco. Compared to heat treatment using the well-known method of supplying a saturated water vapor with a water content of 0.5-10 kg / m, this leads to a condensation of a significantly large amount of energy by condensation and, thus, an instantaneous increase in volume while simultaneously impregnating with moisture and the associated increase the elasticity of the cell wall.
