Definitions

  • the present invention relates to a method for improving the filling capacity of tobacco by treating the tobacco with gases under pressure and then heating after relaxation.
  • bloating of tobacco with nitrous oxide according to GB-PS 13 75 420 or S0 2 according to GB-PS 13 75 820 is also disadvantageous because dinitrogen monoxide can maintain the combustion under certain conditions and is physiologically questionable, while sulfur dioxide is strongly reducing, bleaching and irritating Possesses properties.
  • Another method is to expand tobacco e.g. According to DE-PS 21 43 388 an impregnation of the tobacco with ammonia and carbon dioxide is proposed, whereby the ammonium carbonate which forms in situ can possibly remain in the tobacco.
  • the high-pressure gas treatment causes the gas to be absorbed by the tobacco, the high final pressure, short pressure reduction times and, if appropriate, the moistening of the tobacco prior to the treatment causing the absorption of a sufficiently large amount of gas in the tobacco.
  • the enclosed gas expands through the external supply of heat and generates an outward pressure and thus an expansion of the tobacco structure.
  • the tobacco was preferably additionally moistened before the pressure treatment, while the thermal aftertreatment was carried out either in drying cabinets or by means of microwave or infrared heating, the tobacco drying to a desired final water content.
  • One purpose of the present invention is to provide an economical and energy-saving method for expanding the tobacco, or for improving the filling capacity.
  • Another object of the invention is to improve the method according to DE-OS 29 03 300 in order to increase the filling capacity of the tobacco and to carry it out in a simpler and more energy-saving manner.
  • a method for improving the fillability of tobacco by treating the tobacco with inert gas under pressure and then heating after relaxation is proposed in the tobacco with nitrogen and / or argon at working pressures up to 1000 bar and at a working temperature in Treated range from 0 to 50 ° C and after relaxation is subjected to a brief thermal aftertreatment, which is characterized in that the tobacco to be treated with nitrogen and / or argon has a moisture content of up to about 15%, that the gas high pressure treatment with nitrogen a minimum pressure of 150 bar and with argon at a minimum pressure of 50 bar and that the thermal aftertreatment is carried out in a manner known per se with steam, which is saturated steam or almost saturated water vapor with a water content of 0.5 to 10 kg / m 3 is present, so that the flatulence under the tobacco moisturizing or not takes place under its processing moisture drying conditions.
  • the moisture content up to about 15% usually corresponds to that of processable cigarette tobacco.
  • the duration of the pressure treatment is arbitrary and that of the steam treatment is 0.1 to 10 and preferably 1 to 5 minutes.
  • the method is preferably carried out in such a way that the gas high-pressure treatment is carried out with nitrogen at a minimum pressure of 150 bar and with argon at a minimum pressure of 50 bar.
  • the tobacco can optionally be provided with suitable flavors both before the high-pressure gas treatment and after the thermal steam aftertreatment, without a loss in filling capacity being observed.
  • a very important advantage for the technical implementation of the method according to the invention is that the tobacco used with its normal humidity can be further processed without further process steps when relaxing after the high-pressure gas treatment. In addition, there is no additional moistening, if necessary, as a further process step.
  • Virginia tobacco was treated with nitrogen on a conventional system as described in DE-OS 29 03 300, the weight of the tobacco being 200 g each.
  • the treatment was carried out at the pressures, tobacco moisture levels given in Table I below and at pressure reduction times of approximately 1.3 to 2 minutes.
  • the tobacco treated in this way was then immediately subjected to a thermal aftertreatment lasting about one minute, in that the tobacco was treated once with saturated steam at 100 ° C. according to the invention and, as a comparison, as usual with a microwave or in a drying cabinet.
  • the tobacco present after the high-pressure gas treatment was spread to a fleece immediately after decompression and this was carried out at a constant speed under a steam nozzle.
  • the steam-treated samples were then dried to the desired humidity using hot air.
  • the samples were conditioned for about 36 hours under standard conditions of 21 C and a relative humidity of 60%.
  • the filling power of the samples was determined with a Borgwaldt densimeter after adjustment of the equilibrium moisture.
