    • 专利摘要:
    The tobacco is impregnated with liquid carbon dioxide, then treated in order to convert the liquid carbon dioxide to solid carbon dioxide, and then expanded by evaporation of the solid carbon dioxide, the moisture content of the tobacco used, the pressure of the liquid carbon dioxide in the impregnation stage and the final humidity of the expanded tobacco being controlled relative to each other and excess liquid carbon dioxide being removed from the impregnated tobacco before the conversion to solid carbon dioxide. The method can be carried out simply and without expensive equipment, and permits a high degree of expansion without introducing foreign constituents into the tobacco and without influencing the flavour.

    This invention relates to methods for loosening (increasing) tobacco.
    The purpose of the invention is to effectively increase and improve the quality of the target product.
    The method is carried out as follows.
    An example. The crushed reduced tobacco with a moisture content of 20% in a wire mesh is placed in an autoclave. The autoclave is closed, leaving a hole for the intake of gaseous dioxide. carbon — CO. gas is admitted until a pressure of 28 kg / cm is created, after which the orifice is closed. The autoclave is then filled; with a CO 2 gas at a pressure of 28 kg / cm and with an amount sufficient to cover the tobacco mass. The systems are kept under these conditions for 30 seconds, then the opening in the bottom is opened to pump out. Then the hole is closed, and after 3 minutes, it is opened again to drain the accumulated liquid. This opening is then closed, and the autoclave is opened to the atmosphere through the upper valve in order to reduce the pressure in 180 seconds. When the lid is removed from the autoclave and the net is weighed, it turns out that 8.2 kg of CO is retained by the tobacco. The product can be easily removed and it can be delivered at a controlled rate to the next stage. The loading of tobacco is similar, but it runs during the drain period. It holds 14.3 kg .COg, and the product is very lumpy.
    An increase in volume is used. A vertical dryer with a diameter of 20.3 cm, to which superheated steam is supplied at a speed of 381 m / s at 249 ° C, the product obtained after the treatment of COj is fed into the dryer at a rate of 1.68 kg / min where it contacts the steam for 3 s. The product separated from the cyclone separator, after cooling, has a moisture content of 1 ,, 8%. Its repeated cylindrical volume in terms of moisture 11% is 74.0 g (compared to an initial cylindrical volume of 34.0 g for untreated light tobacco with a standard moisture content of 12.5%) g.
    Cshchindry volume is determined by the following procedure.
    Tobacco filler weighing 10.0 g 1 is placed in a cylinder with a diameter of 3.358 cm and removed within 5 minutes by a piston with a diameter of 3.335 cm; the volume of filler thus obtained is considered as a cylindrical volume. This test is conducted under standard environmental conditions: 23.9 ° C and 60% relative humidity, usually, unless otherwise indicated in the text, it is assumed that the sample is kept under these conditions for 18 hours.
    In order to facilitate the comparison procedure, the magnitude of the cylindrical volume can be recalculated for a specific value of moisture content.
    Example 2. Light tobacco with a moisture content of 20% is treated in the same way as in the example, with a pressure reduction time of 177-190 seconds, except for the exclusion of a three-minute va period and for changes in the extension procedure: rhenium and its conditions. The results and conditions of these pilot tests, reproduced twice, are compared in Table. . .
    Table 1
    From the data table. it can be seen that the optimum filling capacity is observed at low moisture values of the target product obtained from the expansion stage.
    Example 3. Light tobacco with a 50% moisture content of 20% is prepared for milk (IG), as in Example I. Liquid carbon dioxide is admitted into the autoclave chamber, and a pressure of 21, -1 kg / cm is preliminarily created in the chamber.
    55, at the same pressure, liquid carbon dioxide is admitted until tobacco is covered with it, after which tobacco is held for
