  • the cavity segment 126 may be filled with a medium and a flavoring agent.
  • the medium may be in the form of a medium pulp P1, reconstituted tobacco, general cut tobacco leaves, and the like. Desirably, the medium may be in the form of the medium pulp P1 (i.e., medium pulp particles).
  • the medium pulp P1 may be a tobacco pulp or nicotine pulp, but is not limited thereto.
  • the flavoring agent may be in the form of a flavoring agent pulp P2 (i.e., flavoring agent pulp particles), a liquid flavoring material, and the like. Desirably the flavoring agent may be in the form of the flavoring pulp P2.
  • the flavoring agent may include at least one or more of menthol, cis-3-hexenyl, linalool, hexanal, eucalyptol, methyl salicylate, guaiacol, orange oil, lemon oil, star anise oil, peppermint oil, spearmint oil, lime oil, and ginger oil.
  • up to about 70% of the total volume of the cavity segment 126 may be filled with the medium pulp P1 and the flavoring agent pulp P2, and a proportion of the medium pulp P1 in the cavity segment 126 may be at least 50% or more, desirably 60% or more, and more desirably 70% or more of the total amount of pulp included in the cavity segment 126.
  • a sufficient medium may be transferred to a user when the user uses the aerosol-generating article 100, and degradation of a taste of smoking due to the excessive amount of the flavoring agent pulp P2 may be prevented.
  • the size or density of the medium pulp P1 and the flavoring agent pulp P2 may be different from each other by up to 20%, but it is preferable that the medium pulp P1 and the flavoring agent pulp P2 have the same size and/or the same density.
  • the size or density of the medium pulp P1 and the flavoring agent pulp P2 satisfies the above difference range, the medium pulp P1 and the flavoring agent pulp P2 may be uniformly mixed and filled in the cavity segment 126.
  • a vortex is easily formed in the cavity segment 126, so that the medium pulp P1 and the flavoring agent pulp P2 may be uniformly heated.
  • the medium pulp P1 may include a pH adjuster.
  • the pH adjuster may desirably be a basic salt, and may be, for example, potassium carbonate, sodium hydrogen carbonate, calcium oxide, and the like, but is not limited thereto.
  • the pH adjuster which generates the least negative scent during puffing, may be selected and used.
  • the pH adjuster is included in the medium pulp P1
  • the pH of the medium pulp P1 increases, and accordingly, even when the medium is heated with a relatively low temperature, nicotine may be sufficiently transferred from the medium pulp P1.
  • nicotine may be transferred by a small amount of heat delivered to the medium pulp P1 while hot aerosol generated by heating a cartridge 222 by a heater 224 of the aerosol-generating device 200 flows along the airflow path to the aerosol-generating article 100, without directly heating the cavity segment 126.
  • the pH adjuster may be included in the pulp itself by being mixed together during a manufacturing process of the medium pulp P1 or may be disposed separately from the medium pulp P1.
  • the medium pulp P1 may be manufactured by a compression granulation process.
  • the compression granulation process corresponds to a wet process, and has a relatively higher nicotine transition rate of the generated medium pulp P1 compared to the fluidized bed granulation process. Accordingly, when the temperature at which the medium pulp P1 is heated is relatively low, it may be more advantageous in terms of the nicotine transition to include the medium pulp P1 manufactured by the compression granulation process than the medium pulp P1 manufactured by the fluidized bed granulation process.
  • the flavoring agent pulp P2 may or may not include a pH adjuster. Since the flavoring agent pulp P2 has a lower vaporization temperature than the medium pulp P1, the flavor may be sufficiently generated even when the flavoring agent pulp P2 is heated at a low temperature even without the pH adjuster. When the flavoring agent pulp P2 is heated at a temperature excessively higher than the vaporization temperature of the flavoring agent pulp P2, most of the flavoring materials may be transferred at the beginning of smoking, making it difficult to last the scent by the flavoring agent pulp P2. As will be described later with reference to FIGS.
  • the aerosol-generating article 100 is not directly heated by a heater, and aerosol generated by heating in the atomizer 220 of the aerosol-generating device 200 passes through the aerosol-generating article 100 in the direction of the arrow to transition a medium and flavoring agent material. Accordingly, since the flavoring agent pulp P2 is indirectly heated by the heated aerosol, the temperature at which the flavoring agent pulp P2 is heated is lower than in a method where the aerosol-generating article 100 is directly heated or burned, the flavoring agent material may be continuously transferred.
  • the flavoring agent pulp P2 may be manufactured by a fluidized bed granulation process.
  • the flavoring agent pulp P2 may be manufactured by a method of coating a flavoring material on the medium pulp P1 or by a method of layering the flavoring material on a seed material.
  • the fluidized bed granulation process is a process in which a powder material is mixed with hot air heated in a sealed container 500, the powder flows in the container, and a pulp is formed through mixing, granulation and drying processes.
  • the fluidized bed granulation process may include a top-spraying method, a bottom-spraying method, a rotor-spraying method, and the like.
  • the fluidized bed granulation process is divided into the top-spraying method, the bottom-spraying method, and the rotor-spraying method depending on the relationship between a direction in which a liquid binder 510 serving as an adhesive for powder 530 to stick together is sprayed and a direction in which a fluidized air 520 flows.
  • a direction in which the liquid binder 510 is sprayed is generally opposite to a direction in which the fluidized air 520 flows.
  • a direction in which the liquid binder 510 is sprayed is generally the same as a direction in which the fluidized air 520 flows.
  • a direction in which the liquid binder 510 is sprayed is generally perpendicular to a direction in which the fluidized air 520 flows.
  • the filter rod 140 may be positioned downstream of the cavity rod 120 and perform a filtering function for aerosol.
  • the filter rod 140 may include filter materials such as a paper, cellulose acetate fiber, and the like.
