- granule dispersibility refers to a degree of how evenly medium granules or tobacco granules are dispersed in a flat sheet.
- fine powder generated by some of broken medium granules may contaminate the appearance of a filter containing granules.
- granule filter workability refers to a degree of how cleanly the filter may be manufactured without such contamination.
- FIG. 1 is a diagram illustrating a smoking article according to an example embodiment.
- a smoking article 100 may include a medium receiver 110, a humectant receiver 120 on one side of the medium receiver 110 to generate an aerosol, and a filter 130 on the other side of the medium receiver 110.
- the segments of the smoking article 100 that is, the medium receiver 110, the humectant receiver 120, and the filter unit 130, may each be wrapped with a segment wrapper 140, and the segments wrapped by the segment wrapper 140 may be wrapped with a total wrapper 150 to form one smoking article.
- the medium receiver 110 may be filled with a plurality of medium granules 114, and the plurality of medium granules 114 may have an atypical shape.
- the plurality of medium granules 114 is in a general spherical shape, fine powders are less likely to be generated in the process of manufacturing the medium receiver 110, and accordingly, the granular filter workability may be excellent.
- the plurality of medium granules 114 is in a perfectly spherical shape, the dispersibility of the granules decreases in the process of manufacturing the medium receiver 110, which may deteriorate the taste of the smoking article. Accordingly, it is desirable that the medium granules 114 are basically in a spherical shape but also in a shape atypical enough to maintain the granule dispersibility.
- the filter 130 may include a first filter 132 having a cavity therein and a second filter 134 with the internal fully filled with a filtration material.
- the filtration material may include a cellulose-based material (e.g., acetate, paper, etc.).
- the shape of the granules may affect the workability on manufacturing the medium receiver in the smoking article. Accordingly, there is a need to define an appropriate shape of the medium granules during manufacturing a smoking article or an aerosol-generating system.
- FIGS. 2a and 2b are diagrams schematically illustrating when medium granules are applied on a flat sheet, according to an example embodiment.
- FIG. 2a is a diagram illustrating a state of bad granule dispersibility when a flat sheet 112, to which spherical granules 114' are applied, is folded
- FIG. 2b is a diagram illustrating a state of good granule dispersibility when the flat sheet 112, to which atypical granules 114 are applied, is folded
- the spherical granules 114' have low stability of staying on the flat sheet 112 so that the spherical granules 114' may flow in all directions even with a small shock. Accordingly, the granule dispersibility may deteriorate when the flat sheet with the spherical granules 114' disposed thereon is being unfolded, and in the process of manufacturing a medium receiver 110 including the spherical granules 114' by folding the flat sheet 112. On the other hand, referring to FIG. 2b, the atypical granules 114 do not flow easily due to relatively high stability of staying on the flat sheet 112.
- the granule dispersibility may be well maintained in the process of manufacturing the medium receiver 110 including the atypical granules 114 by folding the flat sheet 112 with the atypical granules 114 disposed thereon.
- the stability of the plurality of medium granules 114 on the flat sheet 112 may be improved by applying a binder material having an adhesive component flat sheet 112, but the binder material inhaled together with a heated aerosol during smoking may deteriorate the taste of the smoking article.
- a humectant, not binder material, is applied to surface of the flat sheet 112 before disposing the plurality of medium granules 114 on the flat sheet 112 so that humectant may temporarily improve adhesion between the flat sheet 112 and the plurality of medium granules 114.
- the humectant is a substance for generating an aerosol in the smoking article and not adversely affect of the smoking article.
- the medium receiver 110 of the smoking article 100 may be formed by folding one surface of the flat sheet 112 to face other and additionally folding the flat sheet a plurality of times, and then wrapping the flat sheet 112 folded a plurality of times with a wrapper 140.
- FIGS. 3a and 3b are diagrams schematically illustrating dispersibility of a plurality of medium granules when a flat sheet, to which the plurality of medium granules are disposed, is folded, according to an example embodiment.
- the granule dispersibility in a medium receiver 110 may be maintained in a bad state (see FIG. 3a) and when atypical medium granules 114 are disposed on the flat sheet 112, which then is folded a plurality of times, the granule dispersibility in the medium receiver 110 may be maintained in a good state (see FIG. 3b).
- FIG. 4 is a diagram illustrating an example of roundness of medium granules, according to an example embodiment.
- a roundness may be a numerical value indicating the degree of how round spherical materials, such as particles, beads, and granules, are.
- the roundness may be calculated based on a Maximum Inscribed Circle (MIC) method.
- MIC Maximum Inscribed Circle
- a ratio of Rmax to Rmin represented in percentage is defined as a roundness, in which a radius of a maximum circumscribed circle Cc refers to Rmax and a radius of a maximum inscribed circle Ci refers to Rmin.
- the ratio may be calculated when a circle with the largest radius is drawn among the circles circumscribed to a measured contour, that is, the maximum circumscribed circle Cc, at the center of a circle with the largest radius when an inscribed circle is drawn in the measured contour, such as a granule, that is, the maximum inscribed circle Ci.
- the granular filter workability improves, but the granule dispersibility may be poor.
- the roundness of the medium granules 114 decreases, the granule dispersibility improves but the granular filter workability may be poor. Accordingly, when the medium granules 114 constituting the medium receiver 110 have roundness in an appropriate range, both the granular dispersibility and the granular filter workability may be improved, thus having greater taste of the smoking article.
- the roundness of the granules exceeds 90%, the dispersibility of the granules is generally poor, but when the roundness of the granules is 90% or less, it may be identified that the plurality of medium granules are relatively evenly dispersed when the medium receiver is configured by disposing granules on a flat sheet and then folding the flat sheet a plurality of times.
- the roundness of the granules when the roundness of the granules is less than 30%, the shape of the granules becomes so atypical that fine powders, which are generated due to some of ruptured granules during manufacturing the granules or the medium receiver, may contaminate filters and the like.
- the rate of fine powders to be generated due to the ruptured granules significantly drops, compared to the granules having the lower roundness.
- the hardness of the granules is high enough to significantly decrease the contamination of filters of smoking articles due to the ruptured granules. That is, when the medium granules included in the smoking article have a roundness of 60% or more and 90% or less, both the dispersibility and the filter workability of the granules may be very good.
- the taste of cigarettes may be affected by both the granular dispersibility, which refers to how evenly the granules are dispersed, and the granular filter workability, which refers to whether a filter for the granules is manufactured without being contaminated by the fine powders of the medium granules.
- the smoking taste is very good when the roundness of the granules is 30% or more and 90% or less, and more desirably 60% or more and 90% or less.
- FIGS. 5 and 6 relate to examples in which a smoking article including a plurality of medium granules having the above desirable roundness range is used.
- FIG. 5 is a diagram schematically illustrating an aerosol-generating device according to an example embodiment.
- an aerosol-generating device 200 includes an elongate cavity 210 for accommodating a smoking article 100, a heater 220 and a controller 230.
- the controller 230 may electrically connect to the heater 220 to control a temperature for heating the smoking article 100.
- the aerosol generating device 200 may further include a battery 240 configured to supply power in a process of generating an aerosol.
- FIG. 6 is a diagram schematically illustrating an aerosol-generating system in a state in which a smoking article and an aerosol-generating device are combined, according to an example embodiment.
- an aerosol-generating system 10 may include a smoking article 100 and an aerosol-generating device 200.
- the smoking article 100 may be snugly integrated in the elongate cavity 210 of the aerosol-generating device 200.
- the heater 220 may heat at least a portion of a medium receiver 110 and a humectant receiver 120 in the smoking article 100.
- the roundness of plurality of medium granules 114 in the medium receiver 110 of the smoking article 100 of the aerosol-generating system 10 is desirably 90% or less. This is because, when the roundness of the plurality of medium granules 114 exceeds 90%, the stability of the medium granules 114 to the flat sheet 112 decreases, resulting in poor granule dispersibility.
- the roundness of the plurality of medium granules 114 in the medium receiver 110 included in the smoking article 100 of the aerosol-generating system 10 is desirably 60% or more.
- the hardness of the medium granules 114 may decrease, thus breaking the medium granules 114 even with a slight shock and generating fine powders, so that the generated find powders may contaminate the medium receiver 110 and the filter 130.
- the medium receiver 110 is formed by applying the plurality of medium granules 114 to one side of the flat sheet 112 and then folding the flat sheet 112, the medium granules 114, which are not attached to the flat sheet 112 but are dropped off the flat sheet 112, may be re-used in a subsequent process. Since the minimum hardness of the granules 114 has to be ensured in order for the plurality of medium granules 114 dropped off to be reused, the plurality of medium granules 114 have a desirable roundness of 60% or more.
- FIGS. 7 and 8 illustrate a process for manufacturing a plurality of medium granules having the foregoing desirable roundness range and a shape of granules produced by the process.
- FIG. 7 is a diagram schematically illustrating a fluidized bed granulation process of a top-spraying method among fluidized bed granulation processes.
- the fluidized bed granulation process refers to such a process of generating the granules.
- the fluid bed granulation process may include a top-spraying method, a bottom-spraying method, a powder feeding method, and a rotor-spraying method.
- the top-spraying process is the fluidized bed granulation in which a spraying direction of a liquid binder 510 serving as an adhesive to adhere powders 530 to one another and a flow direction of fluidized air 520 face each other.
- the top-spraying process may have relatively lower roundness of granules generated through this process, compared to the bottom-spaying method where a spraying direction of the liquid binder 510 is the same as a flow direction of the fluidized air 520 and the rotor-spraying method where a spraying direction of the liquid binder 510 is perpendicular to a flow direction of the fluidized air 520. This is illustrated in detail in FIG. 8.
- FIG. 8 is a diagram illustrating the actual shape of granules produced by various fluidized bed granulation processes.
- FIG. 8 illustrates the shapes of granules manufactured by the fluidized bed granulation processes of the rotor-spraying method, the powder feeding method, and the top-spraying method, sequentially.
- the shape of the granules manufactured by the top-spraying method is more irregular and atypical. That is, it may be easy to form granules having a relatively low roundness when using the fluidized bed granulation process of the top-spraying method. This is because a spraying direction of the liquid binder 510 and a flow direction of the fluidizing air 520 are arranged to face each other so that the flow is formed in a reverse direction, allowing particles to grow in an irregular shape.
