It may be desirable to be, but is not limited thereto.

The second cavity unit 142 according to an embodiment is a compartment having a cavity and may be disposed between the second upstream filter unit 144a and the second downstream filter unit 144b. The first cavity part 122 may be filled with media, flavor substances, and other substances that help the movement and taste of aerosol. The form of the material to be filled may be in the form of granules, cut filler, reconstituted cut filler, etc., preferably in the form of granules. In particular, the first cavity portion 122 may include second granules P2, and the second granules P2 may preferably be flavor granules. In this case, the flavoring agent is, for example, menthol, CIS-3-HEXENOL, LINALOOL, HEXANAL, EUCALYPTOL, METHYL SALICYLATE, It may include at least one of guaiacol, orange oil, lemon oil, star anise oil, peppermint oil, spearmint oil, lime oil, and ginger oil.

As described above, the first segment 120 and the second segment 140 each include a first granule P1 (eg, a medium granule) and a second granule P2 (particularly, a flavor granule). As a result, the amount of the flavor material that can be filled in the aerosol-generating article 100 can be increased. In addition, when the proper heating temperature for transferring the medium granules and the appropriate heating temperature for transferring the flavor granules are different, the length of the filter member located between the first segment 120 and the second segment 140, that is, the The first cavity portion ( 122) and the heating temperature of the second cavity portion 142 may be adjusted.

According to an embodiment, the first granule P1 may be a medium granule, and the second granule P2 may be a flavor granule. Hereinafter, the characteristics of each of the first granule (P1) (eg, medium granule) and the second granule (P2) (eg, flavor granule) will be described in detail.

The first granules P1 (eg, medium granules) according to an embodiment may include a pH adjusting agent. The pH adjusting agent may preferably be an alkaline salt, and may be, for example, potassium carbonate, sodium hydrogen carbonate, calcium oxide, etc., but is not limited thereto. In addition, a pH adjusting agent that generates the least amount of negative odor during puffing may be selected and used. When the pH adjusting agent is included in the first granules P1 (eg, medium granules), the pH of the first granules P1 (eg, medium granules) increases, and thus the medium is heated at a relatively low temperature. Even when heated, the medium (particularly, nicotine) can be sufficiently transferred in the first granules P1 (eg, medium granules). The pH adjusting agent may be mixed together during the preparation of the first granules (P1) (eg, medium granules) and included in the granules themselves, or separately in a separate location from the first granules (P1) (eg, medium granules). may be placed.

The first granules P1 (eg, medium granules) according to an embodiment may be prepared by a compression granulation process. The compression granulation process corresponds to a wet process, and thus the medium transfer rate (particularly, nicotine transfer rate) of the resulting medium granules is relatively high compared to the fluidized bed granulation process. Therefore, when the temperature at which the first granules P1 (eg, medium granules) are heated is relatively low compared to the heating temperature of a general cigarette, the first granules P1 prepared by the fluidized bed granulation process (eg, It may be more advantageous for the transfer of the medium (eg nicotine) to include the first granule (P1) (eg, the medium granule) prepared by the compression granulation process rather than the medium granule).

The second granules P2 (eg, flavor granules) according to an embodiment may or may not include a pH adjuster. The second granules (P2) (eg, flavor granules) have a low temperature compared to the medium granules, so they can be sufficiently expressed even when heated at a low temperature without necessarily including a pH adjuster. If the second granules P2 (eg, flavor granules) are heated to a temperature that is excessively high compared to the expression temperature of the second granules P2 (eg, flavor granules), the user may cause an aerosol-generating article ( 100), since most of the flavor material is transferred at the beginning of use, it may be difficult to sustain the flavor of the second granules P2 (eg, flavor granules). As described later with reference to FIGS. 3B and/or 4B , the second cavity portion 142 of the second segment 140 including the second granules P2 in the aerosol-generating article 100 according to an embodiment. ) is not directly heated by the heater, but may be indirectly heated by the heat contained in the aerosol generated by heating. Accordingly, the temperature at which the second granules P2 (eg, flavor granules) are heated in a manner in which the aerosol-generating article 100 is indirectly transferred by the heated aerosol rather than in a manner in which the aerosol-generating article 100 is directly heated or burned is Since it is relatively low, flavoring substances can be carried over continuously.

The second granules P2 (eg, flavor granules) according to an embodiment may be manufactured by a fluidized bed granulation process. Flavor granules may be prepared by coating a flavor material on medium granules or layering a flavor material on a seed material. The fluidized bed granulation process is a process in which powder material is mixed with hot air heated in a closed container 500, the powder is fluidized inside the container, and granules are formed through mixing, granulation, and drying processes. The fluidized bed granulation process may include a top-spraying method, a bottom-spraying method, and a rotor-spraying method, and the like. The fluidized bed granulation process is performed by top-spraying (top -spraying method, bottom-spraying method, and rotor-spraying method. The top-spraying method is a process in which the direction in which the liquid binder 510 is sprayed and the flow direction of the fluidization air 520 face each other, and the bottom-spraying method is a process in which the direction in which the liquid binder 510 is sprayed and the flow direction of the fluidization air 520 face each other. A process in which the flow direction of the air 520 is the same, and the rotor-spraying method is a process in which the direction in which the liquid binder 510 is sprayed and the flow direction of the fluidizing air 520 are perpendicular to each other, which is shown in FIG. Details are shown in Figures 2a to 2c. The second granules P2 (eg, flavor granules) according to an embodiment may be manufactured by a compression granulation process in addition to the fluidized bed granulation process. The compression granulation process corresponds to a wet process, so that the second granules (P2) (eg, flavor granules) produced by the compression granulation process are relatively smaller than those produced by the fluid bed granulation process. Flavoring rates may be high. In the above, the manufacturing method of the second granules P2 (eg, flavor granules) is not limited to the fluidized bed granulation process or the compression granulation process, and those skilled in the art to which the present disclosure belongs will It can be seen that other general-purpose methods other than the manufacturing method may be further included.
