  • the heating temperature was controlled by a temperature controller (Temperature controller TJA-50 manufactured by AS ONE), and when the temperature reached a predetermined temperature, the predetermined carriers shown in Table 1 were allowed to flow through the tobacco packed bed at a flow rate of 55 mL / 2 sec.
  • the temperature of the aerosol circulated in the tobacco packed bed was 30 ° C.
  • the temperature of the aerosol was determined by inserting a thermocouple from the outside of the pipe at a position immediately before the inlet of the tobacco filling layer of the pipe connecting the aerosol generator and the tobacco filling layer, and measuring the temperature of the mixed fluid of the aerosol and air. Further, in Examples 1 to 3, the experiment was carried out after adjusting the aerosol concentration in the carrier so as to be substantially uniform. The air, vapor or aerosol that circulated through the packed bed of tobacco was trapped in an ice-bathed tube, and the liquid was recovered for analysis.
  • Nicotine contained in the recovered liquid was quantified using GC-MS (Agilent 7890B).
  • nicotine in the packed bed was extracted from the tobacco packing with a solvent (methanol), and then nicotine was quantified using GC-MS (7890B manufactured by Agilent).
  • Table 1 shows the recovery rate of nicotine at each carrier and each temperature. In conclusion, it was found that nicotine can be recovered most efficiently by circulating propylene glycol and glycerin aerosols as compared to air.
  • FIG. 1 shows the relationship between the heating temperature of the packed bed and the amount of nicotine recovered when each carrier was used.
  • the horizontal axis shows the heating temperature of the packed bed
  • the vertical axis shows the amount of nicotine recovered. From the results of FIG. 1, it can be seen that the amount of nicotine recovered increases when the temperature of the packed bed is 180 ° C. or higher.
  • the packed bed used in each test was prepared by filling the same tobacco raw material with the same packed amount.
  • the amount of nicotine recovered is the weight of nicotine in the liquid trapped in the ice-cooled tube. Nicotine extracted from the packed bed of tobacco partially adheres to the inner wall of the pipe connecting the ice-cooled tube, which is the collecting device, and the packed bed. Therefore, in this experiment, all the nicotine extracted from the packed bed of tobacco is used. Was not counted as a nicotine recovery.
