Description

Method for manufacturing tobacco medium

[0001] Various embodiments of the present disclosure relate to a method for manufacturing a tobacco medium, and more particularly, to a method for manufacturing a tobacco medium using a paper-cut sheet.

[0002] Recently, there has been a growing demand for technologies that replace the conventional method of producing aerosols by burning cigarettes. For example, research is underway into methods for producing aerosols from liquid or solid aerosol-generating substances, or for producing vapor from liquid aerosol-generating substances and then passing the vapor through a solid flavoring medium to produce a flavored aerosol.

[0003] Accordingly, demand is increasing for systems that generate aerosols by heating cigarettes or aerosol-generating materials using an aerosol-generating device. Recently, methods for generating aerosols using low-temperature heating or non-heating methods have emerged. Research is actively underway to improve nicotine delivery even under low-temperature heating or non-heating conditions.

[0004] One example of a tobacco medium manufacturing method involves using slabs. During the manufacturing process, the slabs are treated with a pH-adjusting solution (e.g., a mixture of water and potassium carbonate), which can cause the slabs to clump together. Determining the moisture content of the slabs is crucial to preventing clumping.

[0005] Meanwhile, the moisture limit available to the tobacco substrate (e.g., the moisture content set by the user) is crucial. Since the pH-adjusting solution contains water, a higher moisture limit allows for more pH-adjusting solution to be processed. Further increasing the pH of the tobacco substrate to produce a tobacco matrix can ultimately increase the nicotine delivery rate of the aerosol-generating product containing the tobacco substrate.

[0006] Therefore, it is important to use a plate-shaped material that can have a high moisture content without clumping together while processing the pH adjustment solution.

[0007] Embodiments provide a method for preparing a tobacco medium by treating a pH adjusting solution on a paper-like substrate.

[0008] The problems to be solved through the embodiments are not limited to the problems described above, and problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the embodiments belong from this specification and the attached drawings.

[0009] A method for manufacturing a tobacco medium according to one embodiment may include the steps of providing a paper-based sheet containing a tobacco concentrate and treating the paper-based sheet with a pH adjusting solution until the moisture content of the paper-based sheet becomes 9 wt% to 12 wt% based on the total weight of the paper-based sheet, wherein the pH adjusting solution may include potassium carbonate (K2CO3) and water, and the amount of potassium carbonate added may be 8 wt% to 14 wt% based on the total weight of the tobacco concentrate.

[0010] An aerosol generating article according to one embodiment may include a shear plug for introducing outside air into the interior of the aerosol generating article, a medium portion including a tobacco medium according to one embodiment, and a filter portion disposed at a position opposite to the shear plug with the medium portion as the center.

[0011] An aerosol generating system according to one embodiment may include an aerosol generating device including an aerosol generating article according to one embodiment, and a storage unit in which an aerosol generating substance is stored, a receiving unit in which the aerosol generating article is received, and a heating unit for heating the aerosol generating substance, wherein a primary aerosol generated by heating the aerosol generating substance by the heating unit may be introduced into a shear plug of the aerosol generating article received in the receiving unit, and while the primary aerosol passes through the aerosol generating article, a secondary aerosol may be generated in the aerosol generating article due to the temperature of the primary aerosol, and the primary aerosol and the secondary aerosol may be mixed and inhaled by a user.

[0012] According to the method for manufacturing a tobacco medium according to the embodiments, the nicotine transfer amount of an aerosol generating article to which the tobacco medium is applied can be improved.

[0013] In addition, according to the method for manufacturing a tobacco medium according to the embodiments, the cost of manufacturing the tobacco medium can be reduced.

[0027] The present disclosure may be implemented in various embodiments as described above or may be implemented in various different forms and is not limited to the embodiments described herein.

[0028] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0029] FIGS. 1 to 3 illustrate aerosol generating systems according to various embodiments of the present disclosure.

[0030] Referring to FIGS. 1 to 3, the aerosol generating system (3) may include an aerosol generating device (1) and an aerosol generating article (2).

[0031] In one embodiment, the aerosol generating device (1) may include at least one of a power source (11), a control unit (12), a sensor (13), and a cartridge (19). At least one of the power source (11), the control unit (12), and the sensor (13) may be disposed inside the body (10) of the aerosol generating device.

[0032] The body (10) may provide a space opened upwardly so that a stick (2), which is an aerosol generating material, may be inserted. The space opened upwardly may be referred to as an insertion space. The insertion space may be formed by being sunken into the interior of the body (10) by a predetermined depth so that at least a portion of the stick (2) can be inserted. At this time, a separate receiving portion (not shown) may be arranged in the sunken portion of the body (10). Since the receiving portion includes the insertion space, the stick (2) may be received in the receiving portion. The depth of the insertion space may correspond to the length of a region of the stick (2) containing an aerosol generating material and / or medium.

[0033] The lower end of the stick (2) is inserted into the inside of the body (10), and the upper end of the stick (2) can protrude outside the body (10). The user can inhale air by putting the upper end of the stick (2) exposed to the outside in his / her mouth.

[0034] The cartridge (19) may contain an aerosol-generating substance in any one of a liquid, solid, gaseous, or gel state. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing substance including volatile tobacco flavoring components, or may be a liquid comprising a non-tobacco substance.

[0035] For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint oil, spearmint oil, and various fruit-flavored ingredients. The flavoring agent may include ingredients that can provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. Additionally, the liquid composition may include an aerosol-forming agent such as glycerin and propylene glycol.

[0036] The cartridge (19) may be formed integrally with the body (10) or may be detachably coupled to the body (10). For example, the cartridge (19) may be mounted on the body (10) by being inserted into the body (10). However, the present invention is not limited thereto, and may be fixed so as not to be detached by the user.

[0037] Meanwhile, the remaining components of the aerosol generating device (1) excluding the cartridge (19) may be referred to as the main body. According to this, the main body may include a power source (11), a control unit (12), and a sensor (13), and the cartridge (19) may be detachably coupled to the main body.

[0038] The cartridge (19) may be mounted on the body (10) while containing an aerosol generating substance inside. However, this is not limited thereto, and the aerosol generating substance may be injected into the cartridge (19) while the cartridge (19) is coupled to the body (10).

[0039] Referring to Fig. 1, the cartridge (19) is formed integrally with the body (10) and can communicate with the insertion space through an airflow channel (CN).

[0040] Referring to FIG. 2, a space is formed on one side of the body (10), and at least a portion of the cartridge (19) is inserted into the space formed on one side of the body (10) so that the cartridge (19) can be mounted on the body (10). The airflow channel (CN) can be defined by a portion of the cartridge and / or a portion of the body (10), and the cartridge (19) can communicate with the insertion space through the airflow channel (CN).

[0041] Meanwhile, the aerosol generating device (1) illustrated in FIG. 1 is illustrated with components arranged in a row. The aerosol generating device (1) illustrated in FIG. 2 is illustrated with a cartridge (19) and a stick (2) arranged in parallel. However, the internal structure of the aerosol generating device (1) is not limited to that illustrated. In other words, depending on the design of the aerosol generating device (1), the arrangement of the power source (11), the control unit (12), the sensor (13), and the cartridge (19) may be changed.

[0042] Referring to FIG. 3, a cartridge (19) can be mounted on the body (10) as in FIG. 2. At this time, the cartridge (19), not the body, can provide the insertion space. That is, in FIG. 3, a stick (2) can be inserted into the interior of the cartridge (19).

[0043] For example, the cartridge (19) may include a storage unit, a receiving unit, and a heating unit (24). The main body may include a cartridge coupling unit to which the cartridge (19) is detachably coupled. A power source (11), which is a component of the main body, may supply power to the cartridge (19) coupled to the cartridge coupling unit, and a control unit (12), which is a component of the main body, may control the operation of the cartridge (19).

[0044] The body (10) can be formed in a structure in which outside air can flow into the interior of the body (10) while the cartridge (19) is inserted. At this time, the outside air flowing into the body (10) can pass through the cartridge (19) and flow into the user's oral cavity.

[0045] The cartridge (19) may include a storage unit (C0) containing an aerosol generating material and / or a heating unit (24) for heating the aerosol generating material in the storage unit (C0). A liquid delivery means impregnating (containing) the aerosol generating material may be disposed inside the storage unit (C0). Here, the liquid delivery means may include a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc. The electrically conductive track of the heating unit (24) may be formed in a coil-shaped structure that winds the liquid delivery means or a structure that contacts one side of the liquid delivery means. The heating unit (24) may be referred to as a cartridge heater (24).

[0046] The cartridge (19) can perform the function of generating an aerosol by converting the phase of an aerosol generating substance inside the cartridge into a gas phase by operating with an electric signal or wireless signal transmitted from the body (10). In this case, the aerosol may mean a gas in a mixed state of vaporized particles and air generated from the aerosol generating substance.

[0047] As the liquid delivery means and the liquid composition absorbed therein are heated by the heating unit (24), an aerosol can be generated. Meanwhile, since the aerosol generating device (1) does not include a heater for heating the stick (2), direct heating of the stick by a heater or the like does not occur (this means non-heating). However, as the hot aerosol generated by the heating unit (24) passes through the stick, vapor may also be generated from the stick.

[0048] Accordingly, while the aerosol (primary aerosol) generated by the heating unit (24) passes through the stick (2), tobacco material can be added to the aerosol, and a secondary aerosol can be generated in the stick (2) by the high-temperature aerosol. The primary aerosol and the secondary aerosol are mixed, and the aerosol to which tobacco material is added can be inhaled into the user's oral cavity through one end of the stick (2).

[0049] Meanwhile, the embodiment is not limited to omitting the heater. In other embodiments, the heater may heat the stick to a relatively low temperature to generate the aerosol (this refers to low-temperature heating).

[0050] The aerosol generating device (1) may include a cap (not shown). The cap may be detachably coupled to the body (10) so as to cover at least a portion of a cartridge (19) coupled to the body (10). The stick (2) may be inserted into the body (10) through the cap.

[0051] The power source (11) can supply power to operate components of the aerosol generating device. The power source (11) can be referred to as a battery. The power source (11) can supply power to at least one of the control unit (12), the sensor (13), and the heating unit (24).

[0052] The control unit (12) can control the overall operation of the aerosol generating device. The control unit can be mounted on a printed circuit board (PCB). The control unit (12) can control the operation of at least one of the power supply (11), the sensor (13), and the cartridge (19). The control unit (12) can control the operation of a display, a motor, etc. installed in the aerosol generating device. The control unit (12) can check the status of each component of the aerosol generating device (1) to determine whether the aerosol generating device (1) is in an operable state.

[0053] The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the heating unit (24) so ​​that the operation of the heating unit (24) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the heating unit (24) and the time for which the power is supplied so that the heating unit (24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

[0054] The sensor (13) may include at least one of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and a cap detection sensor. For example, the sensor (13) may sense at least one of the temperature of the heating unit (24), the temperature of the power source (11), and the temperature inside and outside the body (10). For example, the sensor (13) may sense the user's puff. For example, the sensor (13) may sense whether the stick (2) is inserted into the insertion space. For example, the sensor (13) may sense the color of a part of the wrapper surrounding the outside of the stick (2). For example, the sensor (13) may sense whether the cartridge (19) is mounted. For example, the sensor (13) may sense whether the cap is mounted.

[0055] In one embodiment, the aerosol generating article (2) may include a shear plug (210), a medium portion (220), and a filter portion (230). Hereinafter, components of the aerosol generating article (2) will be described in detail with reference to FIG. 2.

[0056] FIG. 4 is a drawing illustrating an aerosol generating article comprising a medium portion having two segments according to one embodiment.

[0057] In one embodiment, the aerosol generating article (2) may include a shear plug (210), a medium portion (220), and a filter portion (230). Specifically, the shear plug (210), the medium portion (220), and the filter portion (230) may be sequentially arranged in the longitudinal direction of the aerosol generating article (2). In addition to the components illustrated in FIG. 2, other general-purpose components may be further included in the aerosol generating article (2).

[0058] In one embodiment, the shear plug (210) can introduce outside air into the interior of the aerosol-generating article (2). In the present disclosure, when the aerosol-generating article (2) is a non-heated aerosol-generating article, the shear plug (210) can introduce an aerosol generated by a separate component (e.g., a cartridge (19) containing a liquid composition) as outside air into the interior of the aerosol-generating article (2). Specifically, a primary aerosol generated by heating an aerosol-generating material by a heating unit (e.g., a heating unit (24) of FIG. 1) can be introduced into the upper plug of the aerosol-generating article accommodated in the receiving unit.

[0059] In one embodiment, the shear plug (210) may include one of an acetate filter formed of cellulose acetate tow and a paper filter formed of paper. In this case, when the shear plug (210) includes an acetate filter formed of cellulose acetate tow, the shear plug (210) may be manufactured to generate a flavor.

[0060] For example, when the shear plug (210) includes an acetate filter, a flavoring agent containing a flavoring agent may be sprayed onto the acetate filter, and separate fibers coated with the flavoring agent may be included within the acetate filter. In another example, when the shear plug (210) includes an acetate filter, the acetate filter may include a capsule containing a flavoring agent.

[0061] The flavoring agent may include, but is not limited to, menthol.

[0062] For example, the flavoring agent may include plant-based flavorings such as cinnamon, sage, herbs, chamomile, thyme, cinnamon, lavender, bergamot, lemon, orange, cinnamon, jasmine, ginger, vanilla, spearmint, peppermint, acacia, coffee, celery, sandalwood, and cocoa.

[0063] For other examples, the flavoring substances may include animal-derived flavorings such as musk, ambergris, civet, and castor oil.

[0064] For other examples, the flavoring agent may be an alcohol compound, such as geraniol, linalool, anethole, or eugenol. The flavoring agent may be an aldehyde compound, such as vanillin, benzaldehyde, or anisaldehyde. The flavoring agent may be an ester compound, such as isoamyl acetate, linalyl acetate, isoamyl propionate, or linalyl butyrate.

[0065] In one embodiment, the medium (220) may include a tobacco medium. In this case, the tobacco medium may include reconstituted tobacco leaves. Reconstituted tobacco leaves, along with leaf tobacco and flavoring, are important factors that determine the taste and composition of tobacco.

[0066] Depending on the manufacturing method, the sheet-shaped tobacco can be classified into slurry-type and paper-making-type tobacco. In the present disclosure, the tobacco medium constituting the medium portion (220) can be manufactured as a 'paper-making-type sheet-shaped tobacco'.

[0067] Slurry sheet leaves can contain relatively expensive raw materials, accounting for approximately 70% of their total weight. Furthermore, slurry sheet leaves undergo a conveyor belt-type manufacturing process, resulting in a lengthy drying process and, consequently, a relatively high manufacturing cost.

[0068] In contrast, paper-milled sheets can be manufactured using relatively inexpensive paper. Furthermore, paper-milled sheets are manufactured at a low cost because they are made by spraying tobacco concentrate, forming it into sheets, and drying it.

[0069] Furthermore, compared to using slurry plates, using paper-based plates can offer advantages in setting a relatively high moisture limit. Setting the moisture limit is closely related to applying a pH-adjusting solution to the plates, a process described in detail below.

[0070] Table 1 below compares aerosol generating articles comprising a tobacco medium manufactured from slurry sheet and aerosol generating articles comprising a tobacco medium manufactured from paper-milled sheet.

[0071] Slurry sheet-type tobacco sheet pH 7.748.2 Nicotine content 2.99 wt% (relative to the total weight of the tobacco medium) 2.12 wt% (relative to the total weight of the tobacco medium) Nicotine transfer amount 0.03 mg / 9 puff 0.12 mg / 9 puff

[0072] The above data represent the pH, nicotine content, and nicotine transfer amount of tobacco media manufactured by treating two types of slab leaves with a pH adjustment solution, respectively. The data for the slurry slab leaves are the results of experimental condition 2 described below, and the data for the paper-made slab leaves are the results of experimental condition 5 described below. In both types, the pH adjustment solution was treated to the slab leaves in the finished slab product state. The pH adjustment solution may contain water and a pH adjustment agent. For example, the pH adjustment solution is a mixture of water and a pH adjustment agent. That is, the pH adjustment solution may be made by dissolving a pH adjustment agent in water.

[0073] The pH adjuster can adjust the pH of the tobacco medium toward an alkaline level. The pH adjuster can include, but is not limited to, at least one of potassium carbonate (K2CO3), sodium bicarbonate (NaHCO3), and mixtures thereof.

[0074] Referring to Table 1, it can be seen that although the nicotine content relative to the total weight is greater in the slurry sheet, the nicotine transfer amount is four times greater in the paper-milled sheet. This is related to the fact that the pH value of the tobacco medium manufactured from the paper-milled sheet is higher than that of the tobacco medium manufactured from the slurry sheet.

[0075] As the pH of the tobacco medium is adjusted toward an alkaline side by the pH adjuster (i.e., as the pH value of the tobacco medium increases), the amount of nicotine transferred into the tobacco medium may gradually increase. In particular, when the aerosol generating article (2) is a non-heated aerosol generating article, if the pH of the tobacco medium is not adjusted toward an alkaline side (i.e., if the pH of the tobacco medium is close to slightly acidic), the rate of nicotine release at low temperatures may be low, and thus the amount of nicotine transferred may be small. As a result, the user's smoking satisfaction may be reduced.

[0076] By adjusting the pH of the tobacco medium toward an alkaline level using a pH adjustment solution, the aerosol generating article (2) can deliver a sufficient amount of nicotine at low temperatures without being directly heated by a separate heating element. Accordingly, it may be considered advantageous to simply increase the pH by applying more of the pH adjustment solution.

[0077] However, if the pH adjustment solution is excessively applied to the leaf blade, the water contained in the pH adjustment solution can cause the leaf blade to clump. To prevent clumping, an appropriate amount of water or pH adjustment solution must be applied. Therefore, the moisture content of the leaf blade must be set to a certain level (i.e., a moisture limit set by the user), and the pH adjustment solution must be applied accordingly.

[0078] Typically, pH adjustment solutions are made by dissolving a pH adjuster in water. Therefore, a higher moisture limit allows for greater processing capacity. Therefore, it is important to establish a moisture limit available to the platelet to maximize nicotine transfer without clumping the platelet.

[0079] Slurry sheets contain glycerin, making them prone to clumping when treated with pH-adjusting solutions. Paper-milled sheets, lacking glycerin, are relatively drier than slurry sheets. Therefore, the moisture limit of paper-milled sheets can be set higher than that of slurry sheets. From this perspective, paper-milled sheets can handle a greater amount of pH-adjusting solution than slurry sheets.

[0080] Table 2 below shows the moisture content (unit: wt%) relative to the total weight of slurry leaf sheets before and after treatment with the pH adjustment solution, and the amount of potassium carbonate (K2CO3) added relative to the tobacco powder of the slurry leaf sheets (unit: wt%).

[0081] At this time, the slurry sheet may contain 85 wt% of tobacco powder, 5 wt% of guar gum, 5 wt% of pulp, and 5 wt% of glycerin relative to the total weight. At this time, the tobacco powder may be made from a mixture of Burley tobacco leaves and Yellow tobacco leaves in a ratio of 6:4. However, the tobacco powder is not limited thereto, and may be generated from tobacco leaf pieces, tobacco stems, and / or tobacco processing. In addition, the tobacco powder may include crushed tobacco leaves, crushed reconstituted tobacco, etc. In addition, the tobacco powder may correspond to at least one of Yellow tobacco, Burley tobacco, Japanese tobacco, Yang-dry tobacco, and Eum-dry tobacco powder. The pH adjusting solution may be a mixture of water and potassium carbonate, and may mean an aqueous potassium carbonate solution. The moisture content may be measured by the loss on drying (LOD) method.

[0082] Experimental conditions: Moisture content before pH adjustment solution treatment; Moisture content after pH adjustment solution treatment; Amount of K2CO3 added compared to tobacco powder; Realization possibility: 13%, 7%, 5.8%; Possible: 23%, 8.6%, 8.0%; Possible: 33%, 7%, 8.0%; Impossible:

[0083] As mentioned above, slurry platelets contain glycerin, etc., and thus, when treated with a pH adjustment solution, they experience physical property problems such as stickiness and clumping. Therefore, the moisture threshold for pH adjustment solution treatment for slurry platelets cannot be set high. In a state where the moisture threshold is limited, in order to treat the pH adjustment solution to the maximum extent to increase the pH value, the moisture content of the slurry platelets before treatment with the pH adjustment solution must be reduced as much as possible. Referring to Table 2, the moisture content before treatment with the pH adjustment solution was unified at 3 wt% under all experimental conditions.

[0084] Experimental Condition 1 was designed to set the moisture limit of the slurry leaf plate at 7 wt%, considering the physical properties issues that arise during pH adjustment solution treatment. Accordingly, the moisture content during pH adjustment solution treatment was designed to be 7 wt%. Under these conditions, the amount of potassium carbonate added relative to tobacco dust was 5.8 wt%.

[0085] Experimental Condition 2 was designed to increase the pH value further compared to Experimental Condition 1 by treating the pH adjustment solution so that the potassium carbonate addition amount relative to the tobacco fines was 8 wt%, considering that the amount of potassium carbonate added relative to the tobacco fines is proportional to the pH value of the leaf slurry. As a result, the moisture content after the pH adjustment agent treatment was 8.6 wt%. This means that a large amount of water was added, which would cause problems such as stickiness and clumping in the slurry leaf slurry.

[0086] In Experimental Condition 3, compared to Experiment 2, the amount of water was reduced to set the moisture limit to 7 wt%, and the pH adjustment solution was designed to be 8 wt% potassium carbonate added to the tobacco powder. In this case, the solubility of potassium carbonate in water becomes an issue.

[0087] The solubility of potassium carbonate in water is approximately 112 g / 100 mL at room temperature (25 degrees Celsius), and in experimental conditions 1 and 2, a pH-adjusting solution containing the maximum amount of potassium carbonate dissolved in water at room temperature was used. However, in order to achieve an 8 wt% potassium carbonate addition with a moisture content of 7 wt% as in experimental condition 3, a potassium carbonate aqueous solution (pH-adjusting solution) with approximately 158 g / 100 mL of potassium carbonate dissolved in water at room temperature must be used, theoretically. Such a pH-adjusting solution cannot be prepared because it exceeds the solubility of potassium carbonate in water, which is 112 g / 100 mL. Therefore, the experiment is impossible in experimental condition 3.

[0088] Table 3 below shows the moisture content (unit: wt%) relative to the total weight of the paper-milled sheet before and after treatment with the pH adjustment solution, and the amount of potassium carbonate (K2CO3) added (unit: wt%) relative to the tobacco concentrate of the paper-milled sheet. The paper-milled sheet may contain 88 wt% of the tobacco concentrate and 12 wt% of the pulp relative to the total weight. That is, the paper-milled sheet may be treated with a tobacco concentrate containing 88 wt% of the tobacco concentrate and 12 wt% of the pulp relative to the total weight. In this case, the tobacco concentrate may be prepared from a mixture of Burley tobacco leaves and Flue tobacco leaves in a ratio of 6:4. However, the tobacco concentrate is not limited thereto, and may be generated from tobacco leaf scraps, tobacco stems, and / or tobacco processing. In addition, the tobacco concentrate may be prepared from ground tobacco leaves, ground reconstituted tobacco, etc. Additionally, tobacco concentrates can be prepared from at least one of the following tobacco powders: Yellow, Burley, Hwa-dried, Yang-dried, and Yin-dried. The pH-adjusting solution is a mixture of water and potassium carbonate, and may refer to an aqueous potassium carbonate solution. Moisture content can be measured using the loss-on-drying (LOD) method.

[0089] Experimental conditions Moisture content before pH adjustment solution treatment Moisture content after pH adjustment solution treatment Amount of K2CO3 added compared to tobacco concentrate Realization possibility 43% 7% 5.8% Possible 53% 10.5% 11.1% Possible 63% 12% 13.2% Possible 73% 14% 15% Possible

[0090] Since the paper-based sheet does not contain glycerin, it is less sticky or clumpy than the slurry sheet and is relatively dry. Therefore, the moisture threshold can be set relatively high. In experimental conditions 4 to 7, the moisture content before pH adjustment solution treatment was uniformly set at 3 wt%, and the pH adjustment solution containing potassium carbonate dissolved in water at room temperature was treated.

[0091] Experimental condition 4 was designed so that the moisture limit of the paper-cutting type leaf was set to 7 wt%, as in Experimental condition 1 of Table 2, and the moisture content was thus 7 wt% when treated with a pH adjustment solution. Under this condition, the amount of potassium carbonate added relative to the tobacco concentrate was 5.8 wt%.

[0092] Experimental condition 5 was designed so that the moisture limit of the paper-milled sheet leaves was set to 10.5 wt% in consideration of the physical properties problems that arise during pH adjustment solution treatment, and thus the moisture content during pH adjustment solution treatment was 10.5 wt%. Under this condition, the paper-milled sheet leaves did not exhibit any problems such as stickiness or clumping due to water. Under this condition, the amount of potassium carbonate added to the tobacco concentrate was 11.1 wt%, which was a relatively large increase compared to Experimental condition 1 in Table 2 and Experimental condition 4 in Table 3.

[0093] Experimental Condition 6 set the moisture limit of the paper-cut sheet to 12 wt%, and was designed so that the moisture content during pH adjustment solution treatment would be 12 wt%. Under this condition, the amount of potassium carbonate added relative to the tobacco concentrate was 13.2 wt%, which was a relative increase compared to Experimental Condition 5. However, while viscosity increased compared to Experimental Condition 5, this did not cause any problems.

[0094] Experimental Condition 7 was designed to set the moisture limit of the paper-cut sheet to 14 wt%, and thus ensure that the moisture content during pH adjustment solution treatment would be 14 wt%. Under this condition, the amount of potassium carbonate added relative to the tobacco concentrate was 15 wt%, which was a relative increase compared to Experimental Condition 6, but problems such as stickiness and clumping occurred.

[0095] In conclusion, since the amount of potassium carbonate added to the tobacco concentrate is proportional to the amount of pH adjustment solution that can be processed and the pH value of the sheet, it can be seen from Tables 2 and 3 that the paper-milled sheet has a higher pH value than the slurry sheet, and accordingly, the nicotine transfer amount of the aerosol generating product manufactured using the paper-milled sheet is higher.

[0096] In addition, even when manufacturing an aerosol generating product using a paper-making plate, it can be seen that an appropriate amount of pH adjustment solution must be applied to prevent problems such as stickiness and clumping between the paper-making plate leaves.

[0097] Meanwhile, if the pH value of the tobacco medium is high, nicotine may be continuously released from the tobacco medium while the aerosol generating product (2) is stored in an unused state, which may reduce the actual amount of nicotine transferred when the aerosol generating product (2) is subsequently used. In addition, if the pH value of the tobacco medium is excessively high, an off-flavor may be generated from the aerosol generating product (2), which may hinder the user's enjoyment of the product.

[0098] When the aerosol generating article (2) is a non-heated aerosol generating article, the amount of nicotine transferred and the user's smoking satisfaction can be improved when the pH value of the tobacco medium is from about 7 to about 10, or from about 8 to about 9.

[0099] Table 4 below shows the relationship between the amount of potassium carbonate (K2CO3) added (unit: weight%) and pH of the tobacco concentrate in the paper-cut sheet.

[0100] No. Addition of K2CO3 to tobacco concentrate pH 18% Approximately 7.72 11.1% Approximately 8.23 ​​13.2% Approximately 8.74 15% Approximately 9.3

[0101] Referring to Table 4, it can be seen that the pH value increases as the amount of potassium carbonate (K2CO3) added increases. As mentioned above, if the pH value is too high, the amount of nicotine transferred may decrease and the taste may be impaired, so it is necessary to adjust the amount of potassium carbonate (K2CO3) added considering the appropriate range of pH value for sufficient nicotine transfer. In one embodiment, the medium portion (220) may include at least one of an acetate filter formed of cellulose acetate tow and a paper filter formed of paper.

[0102] For example, when the medium portion (220) includes at least one of an acetate filter and a paper filter, a tobacco medium may be filled inside the filter. At this time, the tobacco medium may be filled inside the filter at a concentration of about 2 mg / mm to about 8 mg / mm. Alternatively, the tobacco medium may be filled inside the filter at a concentration of about 4 mg / mm to about 6 mg / mm.

[0103] When the pH of the tobacco medium included in the medium portion (220) is adjusted to an alkaline side through a pH adjustment solution, the amount of nicotine released from the tobacco medium at low temperatures can increase. Accordingly, when the medium portion (220) is manufactured in a manner in which the pH-adjusted tobacco medium is filled into at least one of an acetate filter and a paper filter, the acetate filter or the paper filter can maintain the nicotine released from the tobacco medium in an absorbed state, thereby preventing the released nicotine from being released to the outside of the aerosol generating article (2).

[0104] The medium portion (220) may include a first segment and a second segment. During the manufacturing process of the medium portion (220), the first segment and the second segment are manufactured independently, so that the first segment and the second segment may be connected to each other but may be distinct. The first segment may be adjacent to the shear plug (210), and the second segment may be adjacent to the filter portion (230). The two segments will be described later with reference to FIGS. 5A to 5C .

[0105] In one embodiment, the filter unit (230) may be positioned at a position facing the shear plug (210) with the medium unit (220) as the center. The filter unit (230) may filter at least one of the substances included in the mainstream smoke including the aerosol generated from the medium unit (220).

[0106] In one embodiment, the filter unit (230) may be implemented in various shapes. For example, the filter unit (230) may be a cylindrical rod, or may be a tubular rod including a hollow portion therein. Alternatively, the filter unit (230) may be a recessed rod.

[0107] In one embodiment, the filter unit (230) may include one of an acetate filter formed of cellulose acetate tow and a paper filter formed of paper. In this case, when the filter unit (230) includes an acetate filter formed of cellulose acetate tow, the filter unit (230) may be manufactured to generate a flavor.

[0108] For example, when the filter unit (230) includes an acetate filter, a flavoring agent containing a flavoring agent may be sprayed onto the acetate filter, and separate fibers coated with the flavoring agent may be included inside the acetate filter. For another example, when the filter unit (230) includes an acetate filter, the acetate filter may include a capsule containing a flavoring agent. The flavoring agent that may be included in the filter unit (230) may be the same as or similar to the flavoring agent that may be included in the shear plug (210).

[0109] In one embodiment, one of the shear plug (210) and the filter element (230) may include a flavoring substance.

[0110] For example, if the shear plug (210) includes a capsule containing a flavoring substance or includes fibers coated with a flavoring liquid containing a flavoring substance, the filter unit (230) may not include a flavoring substance. That is, if the shear plug (210) includes a flavoring substance, the filter unit (230) may include a recessed rod formed of cellulose acetate tow or a tube formed of paper.

[0111] For another example, if the filter unit (230) includes a capsule containing a flavoring substance or includes fibers coated with a flavoring liquid containing a flavoring substance, the shear plug (210) may not include a flavoring substance. That is, if the filter unit (230) includes a flavoring substance, the shear plug (210) may include an acetate filter formed of cellulose acetate tow or a tube formed of paper.

[0112] The aerosol generating article (2) may be manufactured in a cylindrical shape. In one embodiment, when the aerosol generating article (2) is manufactured in a cylindrical shape, the length of the aerosol generating article (2) may be about 24 mm to about 72 mm. For example, the length of the shear plug (210) may be about 6 mm to about 18 mm, the length of the medium portion (220) may be about 12 mm to about 36 mm, and the length of the filter portion (230) may be about 6 mm to about 18 mm. However, the length of the aerosol generating article (2) and its constituent elements is not limited thereto and may vary depending on the manufacturer's design.

[0113] Below, two segments of the medium section (220) are described.

[0114] Figures 5a to 5c are cross-sectional views of the aerosol generating article illustrated in Figure 4 cut in the longitudinal direction and viewed in the XX' direction.

[0115] Referring to FIGS. 5A to 5C, an aerosol generating article (2) according to one embodiment may include a shear plug (210), a medium portion (220), and a filter portion (230). In the drawings, the shear plug (210) is illustrated as including a paper filter (e.g., a tube) formed of paper, and the filter portion (230) is illustrated as including an acetate filter including a capsule (232) containing a flavoring substance, but is not limited thereto. In another embodiment, the shear plug (210) may include an acetate filter including a capsule (232) containing a flavoring substance, and the filter portion (230) may include a recessed rod formed of cellulose acetate tow.

[0116] According to one embodiment, the medium portion (220) of the aerosol generating article (2) may include two segments, each segment including different elements. For example, the first segment (240) of the medium portion (220) may include a tobacco medium (222) made of a paper-like sheet, and the second segment (250) may include a cooling element (226). In this case, the cooling element (226) may correspond to either a tube filter or a pipe filter, and the suction resistance of the aerosol generating article (2) may be reduced through the cooling element (226).

[0117] Referring to FIG. 5a, a first segment (240) including a tobacco medium (222) may be placed in a compartment A (e.g., compartment A of FIG. 4) of the medium section (220), and a second segment (250) including a cooling element (226) may be placed in a compartment B (e.g., compartment B of FIG. 4) of the medium section (220).

[0118] That is, the outside air introduced through the front plug (210) can be sequentially passed to the second segment (250) and the filter unit (230) after being mixed with components such as nicotine released from the tobacco medium (222) of the first segment (240).

[0119] Referring to FIG. 5b, the second segment (250) including the cooling element (226) may be placed in section A of the medium section (220), and the first segment (240) including the tobacco medium (222) may be placed in section B of the medium section (220). That is, the outside air introduced through the shear plug (210) may be sequentially passed to the first segment (240) and the filter section (230) after its temperature is lowered through the cooling element (226) of the second segment (250).

[0120] In another embodiment, the medium portion (220) may include two segments containing the same element. For example, the first segment (240a) and the second segment (240b) of the medium portion (220) may each contain a tobacco medium (222).

[0121] Referring to FIG. 5c, a first segment (240a) including a tobacco medium (222) may be placed in a section A of the medium section (220), and a second segment (240b) including a tobacco medium (222) may be placed in a section B of the medium section (220).

[0122] In one embodiment, the first segment (240a) can be manufactured by filling the tobacco medium (222) into an acetate filter, and the second segment (240b) can be manufactured by filling the tobacco medium (222) into a paper filter.

[0123] However, this is only one embodiment and is not limited thereto. In another embodiment, the first segment (240a) may be manufactured by filling the tobacco medium (222) into a paper filter, and the second segment (240b) may be manufactured by filling the tobacco medium (222) into an acetate filter. In addition, the first segment (240a) and the second segment (240b) may be manufactured by filling the tobacco medium (222) into an acetate filter, or may be manufactured by filling the tobacco medium (222) into a paper filter.

[0124] Table 5 below is data analyzing the mainstream smoke (e.g., aerosol) components of the aerosol generating article (2) illustrated in FIGS. 5a to 5c. In this case, the medium portion (220) of the aerosol generating article (2) includes a tobacco medium (222) manufactured from a paper-like sheet.

[0125] Nicotine transfer amount (mg) Total smoke condensate (mg) TE part Nicotine transfer amount (mg) ME part Nicotine transfer amount (mg) Degree 5a 0.15 34.2 0.6 9 0.35 Degree 5b 0.09 32.2 0.28 0.62 Degree 5c 0.25 29.4 0.8 7 0.93

[0126] The experiment was conducted as follows. According to the ISO (International Organization for Standardization) smoking conditions, a total of 20 aerosol-generating articles (2) were smoked using an automatic smoking machine, and the mainstream smoke of the cigarette smoke was captured by a Cambridge filter. After smoking, the total particulate matter (TPM) captured by the Cambridge filter was extracted with isopropyl alcohol to measure the nicotine content. The TE (tobacco end) part described in Table 5 may refer to the distal end of the aerosol-generating article or the end inserted into the aerosol-generating device. The ME (mouth end) part may refer to the proximal end of the aerosol-generating article or the end that comes into contact with the user's mouth.

[0127] As a result of the experiment, the amount of nicotine transferred and the amount of nicotine transferred were measured to be higher when the tobacco medium (222) was applied to two segments (e.g., FIG. 5c) compared to when the tobacco medium (222) was applied to one segment (e.g., FIGS. 5a and 5b). In particular, it can be seen that the amount of nicotine transferred and the amount of nicotine transferred were higher compared to the total smoke condensate value indicating the amount of vaporization. This result is because more tobacco medium (222) was applied to the medium section (220).

[0128] Figure 6 is a flowchart showing a method for manufacturing a tobacco medium according to one embodiment.

[0129] Referring to Figure 6, the process of manufacturing a tobacco medium from a paper-like leaf is depicted in chronological order.

[0130] At step S610, the manufacture of the tobacco medium may begin with the step of providing a paper-rolled sheet. The paper-rolled sheet may be produced through the following process.

[0131] First, tobacco leaves are heated to a high temperature. The tobacco liquid component (which, when concentrated, can become tobacco concentrate) is then separated, leaving behind tobacco-free residue. These residues can be dried to form paper. This paper is called "paper." The tobacco concentrate, which is the result of the separation and concentration of the tobacco liquid component in the previous step, can be mixed with pulp to form a tobacco concentrate. For example, a tobacco concentrate may contain 88% tobacco concentrate and 12% pulp by weight, based on the total weight.

[0132] By spraying tobacco concentrate onto a paper sheet, processing the paper sheet with the tobacco concentrate applied thereon into a sheet, and then re-drying the sheet at a high temperature, a paper-making sheet can be produced. At this time, the tobacco concentrate can be included in the paper-making sheet at 30 to 40 wt% based on the total weight of the paper sheet.

[0133] At step S620, a first flavoring treatment step may be performed on the paper-like sheet. The first flavoring agent may include a humectant. Furthermore, the first flavoring agent may include the aforementioned plant-based flavoring agent, animal-based flavoring agent, alcohol-based compound, aldehyde-based compound, ester-based compound, and combinations thereof.

[0134] The first flavoring step can impart flexibility and moisture retention to the tobacco leaf and enhance the unique flavor of the tobacco. This first flavoring step can be performed before the paper-rolled tobacco leaf is cut into pieces and becomes a finished product. This first flavoring step can improve workability in the manufacture of tobacco media.

[0135] At step S630, the first flavor-treated paper-like sheet may be dried. During the drying process, some of the first flavoring agent may evaporate. To compensate for the flavor loss due to the evaporation of the flavoring agent, a second flavoring treatment may be performed.

[0136] At step S640, the dried paper-cut sheet may be cut into pieces. The cut paper-cut sheet may be processed as a finished product. By cutting the paper-cut sheet before the second flavoring treatment, the effect of the second flavoring can be enhanced.

[0137] At step S650, a pH adjustment solution may be applied to the paper-like sheet. This pH adjustment solution may be applied alone or in conjunction with the secondary flavoring treatment described below. The pH adjustment solution may include, for example, potassium carbonate and water. Depending on the solubility of potassium carbonate, the pH adjustment solution may be prepared by dissolving potassium carbonate in water to the maximum extent possible.

[0138] In the step of treating the pH adjustment solution, a process of spraying the pH adjustment solution onto the paper-making plate leaf at a rate of 1 L per minute for 5 minutes and mixing the paper-making plate leaf may be included so that the pH adjustment solution can evenly contact the paper-making plate leaf. At this time, the ambient temperature may be maintained at 20 to 30 degrees Celsius, or room temperature (25 degrees Celsius).

[0139] The pH adjusting solution can be applied to the paper-rolled tobacco sheet until the moisture content of the paper-rolled tobacco sheet reaches 9 wt% to 12 wt%, or 10 wt% to 11 wt%, or 10.5 wt%, based on the total weight of the paper-rolled tobacco sheet. As a result, the final moisture content of the tobacco medium can reach 9 wt% to 12 wt%, or 10 wt% to 11 wt%, or 10.5 wt%. By setting the moisture content in this manner, the paper-rolled tobacco sheet can be prevented from clumping together and the pH value of the tobacco medium can be increased.

[0140] At this time, the amount of potassium carbonate added relative to the total weight of the tobacco concentrate included in the paper-making plate leaf may be 8 wt% to 14 wt%, or 10 wt% to 12 wt%, or 10.5 wt% to 11.5 wt%, or 11.1 wt%. By setting the amount of potassium carbonate added relative to the total weight of the tobacco concentrate in this way, the pH value of the tobacco medium can be prevented from increasing beyond the appropriate range. Accordingly, the phenomenon of a decrease in nicotine transfer and a decrease in taste sensation due to an increase in the pH value can be prevented.

[0141] Meanwhile, in step S650, a second flavoring treatment step, in which a second flavoring substance different from the first flavoring substance is applied to the paper-like plate of the cut finished product, may be performed together with the pH adjustment solution treatment step. The second flavoring substance may include any one of the aforementioned plant-based flavorings, animal-based flavorings, alcohol compounds, aldehyde compounds, and ester compounds. Furthermore, the second flavoring substance may be composed of only one of the aforementioned flavorings and compounds. The secondary flavoring treatment may be omitted depending on the embodiment.

[0142] In addition, according to the method for manufacturing a tobacco medium according to the embodiments, the amount of nicotine transferred to an aerosol generating article to which the tobacco medium is applied can be improved.

[0143] In addition, according to the method for manufacturing a tobacco medium according to the embodiments, the cost of manufacturing the tobacco medium can be reduced.
