Description

TECHNICAL FIELD

[0001] Various embodiments of the present application relate to a method of manufacturing a tobacco medium, and more particularly, to a method of manufacturing a tobacco medium using paper-making type reconstituted tobacco. BACKGROUND

[0002] In recent years, there is an increasing demand for a technology for replacing a method of supplying an aerosol by burning a conventional cigarette. For example, a method being researched is as follows: generating an aerosol from an aerosol generating material in a liquid state or a solid state, or generating a vapor from an aerosol generating material in a liquid state, and then supplying an aerosol having a flavor by passing the generated vapor through a flavor medium in a solid state, etc.

[0003] Accordingly, there is an increasing demand for a system of heating a cigarette or an aerosol generating material using an aerosol generating device to generate an aerosol. In recent years, a method of generating an aerosol in a low-temperature heating or non-heating manner is on the rise. Research is actively being conducted to improve nicotine delivery even in a low-temperature heating or non-heating manner. SUMMARY

[0004] PROBLEMS TO BE SOLVED BY THE INVENTION One example of manufacturing a tobacco medium is a method of using reconstituted tobacco. In the manufacturing process, the reconstituted tobacco needs to be treated with a pH adjusting solution (e.g., a mixture of water and potassium carbonate), and in this process, the reconstituted tobacco can be agglomerated. It is important to set the moisture content of the reconstituted tobacco to prevent the reconstituted tobacco from being agglomerated.

[0005] On the other hand, the moisture limit available for the reconstituted tobacco (e.g., the moisture content set by a user) is very important. Since the pH adjusting solution contains water, the higher the moisture threshold, the more the pH adjusting solution can be treated. When the pH of the reconstituted tobacco is further increased and a tobacco medium is prepared, the nicotine delivery amount of an aerosol generating article including the tobacco medium can eventually be increased.

[0006] Therefore, when treated with a pH adjusting solution, it is important to use reconstituted tobacco that can be set to a high moisture content without being agglomerated with each other.

[0007] Embodiments provide a method of manufacturing a tobacco medium by treating paper-making type reconstituted tobacco with a pH adjusting solution.

[0012] Effects of Invention The manufacturing method of the tobacco medium according to the embodiment can increase the amount of nicotine delivered by the aerosol generating article using the tobacco medium.

[0027] The present invention may be implemented in the forms that can be realized in the various embodiments described above, or may be implemented and practiced in many different forms, and is not limited to the embodiments described herein.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] Figures 1 to 3 An aerosol generation system according to various embodiments of the present invention is shown.

[0030] Reference Figures 1 to 3 The aerosol generation system 3 may include an aerosol generation device 1 and an aerosol generation article 2.

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

[0032] The main body 10 may have an upwardly opening space for inserting the aerosol-generating article, i.e., the rod 2. This upwardly opening space may be referred to as the insertion space. The insertion space may be formed to be recessed to a predetermined depth towards the interior of the main body 10 to allow at least a portion of the rod 2 to be inserted. In this case, a separate receiving portion (not shown) may also be provided in the recessed portion of the main body 10. The receiving portion includes the insertion space, and therefore the rod 2 can also be accommodated in the receiving portion. The depth of the insertion space may correspond to the length of the region of the rod 2 containing the aerosol-generating substance and / or medium.

[0033] The lower end of rod 2 can be inserted into the interior of the main body 10, and the upper end of rod 2 can protrude outward from the main body 10. The user can put the exposed upper end of rod 2 into their mouth and inhale air.

[0034] The interior of the cartridge 19 may include an aerosol-generating substance in any of the following states: liquid, solid, gas, or gel. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it may be a liquid containing non-tobacco substances.

[0035] For example, the liquid composition may contain water, solvent, ethanol, plant extracts, fragrance, flavoring agent, or vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring ingredients. The flavoring agent may contain ingredients capable of providing the user with a variety of fragrances or flavors. The vitamin mixture may be a mixture of at least one of vitamins A, B, C, and E, but is not limited to. Additionally, the liquid composition may contain aerosol forming agents (such as glycerin and propylene glycol).

[0036] The cartridge 19 may be integrally formed with the body 10 or detachably attached to the body 10. For example, the cartridge 19 may be installed in the body 10 by inserting it into the body 10. However, it is not limited to this; the cartridge 19 may also be fixed so that the user cannot remove it.

[0037] On the other hand, the components of the aerosol generating device 1 other than the cartridge 19 can be referred to as the main body. Accordingly, the main body may include a power supply 11, a control unit 12, and a sensor 13, and the cartridge 19 is detachably attached to the main body.

[0038] The cartridge 19 can be installed on the main body 10 while containing the aerosol generating substance inside. However, it is not limited to this; the aerosol generating substance can also be injected into the interior of the cartridge 19 while it is attached to the main body 10.

[0039] Reference Figure 1 The smoke cartridge 19 can be integrally formed with the main body 10 and is connected to the insertion space through the airflow channel CN.

[0040] Reference Figure 2 A space is formed on one side of the main body 10, and at least a portion of the cartridge 19 can be inserted into the space formed on one side of the main body 10, so that the cartridge 19 can be installed in the main body 10. The airflow channel CN ​​can be defined by a portion of the cartridge and / or a portion of the main body 10, and the cartridge 19 can communicate with the insertion space through the airflow channel CN.

[0041] on the other hand, Figure 1 The aerosol generating device 1 shown has its components arranged in a row. Figure 2 The aerosol generating device 1 shown depicts a cartridge 19 and a stick 2 arranged in parallel. However, the internal structure of the aerosol generating device 1 is not limited to the illustration. In other words, the configuration of the power supply 11, control unit 12, sensor 13, and cartridge 19 can be changed depending on the design of the aerosol generating device 1.

[0042] Reference Figure 3 ,like Figure 2 As shown, the smoke cartridge 19 can be installed in the main body 10. In this case, the smoke cartridge 19 (not the main body) provides an insertion space. That is, in... Figure 3In the middle, rod 2 can be inserted into the inside of smoke cartridge 19.

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

[0044] The main body 10 can be configured such that, with the cartridge 19 inserted, external air can flow into the interior of the main body 10. At this time, the external air flowing into the main body 10 can pass through the cartridge 19 and flow to the user's mouth.

[0045] The cartridge 19 may include: a storage section C0 containing an aerosol-generating substance; and / or a heating section 24 for heating the aerosol-generating substance in the storage section C0. A liquid delivery device for impregnating (containing) the aerosol-generating substance may be disposed inside the storage section C0. The liquid delivery device may include a core material, such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic. The conductive track of the heating section 24 may be formed as a coil wound around the liquid delivery device or in contact with one side of the liquid delivery device. The heating section 24 may be referred to as a cartridge heater 24.

[0046] The cartridge 19 can operate via electrical or wireless signals transmitted from the main body 10, changing the phase of the aerosol-generating substance inside the cartridge into a gaseous phase, thereby performing the function of generating aerosols. Here, aerosol can refer to a gaseous mixture of vaporized particles generated by the aerosol-generating substance and air.

[0047] Aerosols can be generated by heating the liquid transport device and the liquid composition absorbed by it through the heating section 24. On the other hand, since the aerosol generating device 1 does not include a heater for the heating rod 2, it is not possible to directly heat the rod through a heater or the like (meaning no heating). However, steam can also be generated in the rod as the hot aerosol generated in the heating section 24 passes through it.

[0048] Therefore, as the aerosol (primary aerosol) generated by the heating unit 24 passes through the rod 2, the aerosol may contain tobacco substances, and secondary aerosols can be generated in the rod 2 through the high-temperature aerosol. The primary and secondary aerosols are mixed, and the aerosol containing tobacco substances can be inhaled into the user's mouth through one end of the rod 2.

[0049] On the other hand, the heater is omitted in the embodiments, but it is not limited thereto. In another embodiment, the heater may heat the rod at a lower temperature to generate an aerosol (which means low-temperature heating).

[0050] The aerosol generating device 1 may include a cover (not shown). The cover is detachably attached to the body 10 to cover at least a portion of the cartridge 19 attached to the body 10. A rod 2 may penetrate the cover and be inserted into the body 10.

[0051] Power supply 11 provides power to enable the components of the aerosol generating device to operate. Power supply 11 may be referred to as a battery. Power supply 11 can supply power to at least one of the control unit 12, sensor 13, and 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, sensor 13, and cartridge 19. The control unit 12 can control the operation of the display, motor, etc., installed in the aerosol generating device. The control unit 12 can determine whether the aerosol generating device 1 is in an operational state by checking the status of each component of the aerosol generating device 1.

[0053] The control unit 12 can analyze the results detected by the sensor 13 and control the subsequent processing. For example, the control unit 12 can control the power supplied to the heating unit 24 based on the results detected by the sensor 13, so as to start or stop the operation of the heating unit 24. For example, the control unit 12 can control the amount of electricity supplied to the heating unit 24 and the power supply time based on the results detected by the sensor 13, so as to enable the heating unit 24 to heat to a specified temperature or maintain an appropriate temperature.

[0054] 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, sensor 13 may detect at least one of the temperature of the heating element 24, the temperature of the power supply 11, and the internal and external temperatures of the body 10. For example, sensor 13 may detect a user's puff. For example, sensor 13 may detect whether the stick 2 is inserted into the insertion space. For example, sensor 13 may detect the color of a portion of the outer packaging paper of the stick 2. For example, sensor 13 may detect whether the cartridge 19 is installed. For example, sensor 13 may detect whether the cap is installed.

[0055] In one embodiment, the aerosol generating article 2 may include a front-end plug 210, a medium section 220, and a filter section 230. Referring below... Figure 2 The constituent elements of aerosol-generating article 2 are described in detail.

[0056] Figure 4 This is a diagram illustrating an embodiment of an aerosol-generating article including a medium section having two segments.

[0057] In one embodiment, the aerosol generating article 2 may include a front-end insert 210, a medium section 220, and a filter section 230. Specifically, the front-end insert 210, the medium section 220, and the filter section 230 may be arranged sequentially along the length direction of the aerosol generating article 2. In addition, besides Figure 2 In addition to the constituent elements shown, the aerosol generating article 2 may also include other general constituent elements.

[0058] In one embodiment, the front-end plug 210 can introduce external air into the interior of the aerosol generating article 2. In this invention, when the aerosol generating article 2 is a non-heated aerosol generating article, the front-end plug 210 can introduce aerosol generated by a single component (e.g., a cartridge 19 containing a liquid composition) as external air into the interior of the aerosol generating article 2. Specifically, this is achieved through a heating element (e.g., Figure 1 The heating section 24) heats the aerosol generating material to generate primary aerosols, which can flow into the upper insert of the aerosol generating article contained in the containment section.

[0059] In one embodiment, the front-end plug 210 may include one of an acetate filter formed from cellulose acetate tow and a paper filter formed from paper. When the front-end plug 210 includes an acetate filter formed from cellulose acetate tow, the front-end plug 210 may be manufactured in a fragrance-producing manner.

[0060] For example, when the front-end plug-in 210 includes an acetic acid filter, a fragrance liquid containing a flavoring substance can be sprayed onto the acetic acid filter, and individual fibers coated with the fragrance liquid can be included inside the acetic acid filter. As another example, when the front-end plug-in 210 includes an acetic acid filter, the acetic acid filter can include a capsule containing a flavoring substance.

[0061] Flavoring substances may include, but are not limited to, menthol.

[0062] For example, aromatic substances may also include cinnamon, sage, herbs, chamomile, galangal, persimmon, lavender, bergamot, lemon, orange, cinnamon, jasmine, ginger, vanilla, spearmint, peppermint, acacia, coffee, celery, sandalwood, and cocoa, among other plant-based flavorings.

[0063] For example, fragrance substances may also include animal-derived fragrances such as musk, ambergris, castoreum, and civet.

[0064] For example, aroma compounds may also include alcohols such as geraniol, linalool, anethole, and eugenol. Aroma compounds may also include aldehydes such as vanillin, benzaldehyde, and anisaldehyde. Aroma compounds may also include esters such as isoamyl acetate, linalyl acetate, isoamyl propionate, and linalyl butyrate.

[0065] In one embodiment, the medium section 220 may include a tobacco medium. In this case, the tobacco medium may include reconstituted tobacco leaves. Reconstituted tobacco leaves, along with tobacco leaves and flavorings, are important factors in determining the flavor and composition of tobacco.

[0066] Depending on the manufacturing method, reconstituted tobacco can be classified into pulp-based and paper-based types. In this invention, the tobacco medium constituting the medium section 220 can be manufactured into "paper-based reconstituted tobacco".

[0067] Reconstituted tobacco leaves can contain approximately 70% of the relatively expensive raw leaves by weight. Furthermore, reconstituted tobacco leaves undergo a conveyor belt manufacturing process with a lengthy drying process, resulting in relatively high manufacturing costs.

[0068] In contrast, paper-based reconstituted tobacco can be manufactured using relatively inexpensive base paper. Furthermore, paper-based reconstituted tobacco is produced by spraying tobacco concentrate into sheets and then drying them, resulting in lower manufacturing costs.

[0069] Furthermore, compared to reconstituted tobacco using pulp, paper-based reconstituted tobacco offers advantages in terms of setting a relatively higher moisture limit. The moisture limit setting is closely related to the treatment of the reconstituted tobacco with a pH-adjusting solution, which will be explained in detail below.

[0070] Table 1 below compares aerosol-generating articles containing tobacco media made from pulp-reconstituted tobacco leaves with aerosol-generating articles containing tobacco media made from paper-reconstituted tobacco leaves.

[0071] Table 1

[0072] The above data represent the pH, nicotine content, and nicotine transfer of tobacco media produced by treating two types of reconstituted tobacco leaves with a pH-adjusting solution. The data for pulp-based reconstituted tobacco leaves are the results from experimental condition 2 (described later), and the data for paper-based reconstituted tobacco leaves are the results from experimental condition 5 (described later). Both types of reconstituted tobacco leaves were treated with the pH-adjusting solution while still in their finished product state.

[0073] pH-adjusting solutions may contain water and a pH-adjusting agent. For example, a pH-adjusting solution is a mixture of water and a pH-adjusting agent. That is, a pH-adjusting solution is made by dissolving a pH-adjusting agent in water.

[0074] pH adjusters can adjust the pH of tobacco media to alkaline. pH adjusters may include, but are not limited to, at least one of potassium carbonate (K2CO3), sodium bicarbonate (NaHCO3), and mixtures thereof.

[0075] Referring to Table 1, even though the proportion of nicotine in pulp-reconstituted tobacco is larger relative to the total weight, the nicotine transfer in paper-reconstituted tobacco is four times that in pulp-reconstituted tobacco. This is related to the fact that the pH value of tobacco media made from paper-reconstituted tobacco is higher than that of tobacco media made from pulp-reconstituted tobacco.

[0076] By using pH adjusters, the nicotine delivery of the tobacco medium can gradually increase as the pH of the tobacco medium is adjusted to alkalinity (i.e., the higher the pH of the tobacco medium). In particular, when aerosol-generating article 2 is a non-heated aerosol-generating article, if the pH of the tobacco medium is not adjusted to alkalinity (i.e., the pH of the tobacco medium is close to weakly acidic), the nicotine release rate is slower at low temperatures, resulting in lower nicotine delivery. This can reduce user smoking satisfaction.

[0077] By adjusting the pH of the tobacco medium to alkaline using a pH-adjusting solution, sufficient nicotine can be delivered at low temperatures even without direct heating via a separate heating element. Therefore, it can be considered advantageous to increase the pH simply by treating with more pH-adjusting solution.

[0078] However, if reconstituted tobacco is overtreated with a pH-adjusting solution, the water in the solution can cause the tobacco to clump. To prevent clumping, the water or pH-adjusting solution needs to be treated appropriately. Therefore, the moisture content of the reconstituted tobacco needs to be set at a certain level, i.e., a moisture limit needs to be set (e.g., a user-defined moisture content), and the reconstituted tobacco should be treated with the pH-adjusting solution according to the set amount.

[0079] Typically, pH-adjusting solutions are used by dissolving a pH adjuster in water; therefore, the higher the moisture threshold, the more pH-adjusting solution can be used for treatment. Thus, in the case of reconstituted tobacco without clumping, it is important to set the moisture limit available for reconstituted tobacco in a way that maximizes nicotine delivery.

[0080] Pulp-reconstituted tobacco contains glycerol, making it prone to clumping when treated with pH-adjusting solutions. Paper-reconstituted tobacco, on the other hand, does not contain glycerol and is therefore relatively drier than pulp-reconstituted tobacco. Consequently, the moisture limit for paper-reconstituted tobacco can be higher than that for pulp-reconstituted tobacco. From this perspective, paper-reconstituted tobacco can be treated with a larger volume of pH-adjusting solution compared to pulp-reconstituted tobacco.

[0081] Table 2 below shows the moisture content (in weight %) relative to the total weight of the reconstituted tobacco leaves and the amount of potassium carbonate added relative to the tobacco powder in the reconstituted tobacco leaves before and after treatment with the pH-adjusting solution (in weight %).

[0082] At this point, relative to the total weight of the reconstituted tobacco leaves, the reconstituted tobacco leaves may contain 85% by weight of tobacco powder, 5% by weight of guar gum, 5% by weight of pulp, and 5% by weight of glycerin. The tobacco powder may be made from a mixture of burley tobacco and flue-cured tobacco leaves in a 6:4 ratio. However, tobacco powder is not limited to this and may also be generated from tobacco scraps, stems, and / or tobacco processing. Additionally, tobacco powder may include pulverized tobacco leaves, pulverized reconstituted tobacco, etc. Furthermore, tobacco powder may correspond to at least one type of tobacco powder from flue-cured, burley, flambéed, sun-cured, and air-cured tobacco. The pH-adjusting solution is a mixture of water and potassium carbonate, and may refer to an aqueous solution of potassium carbonate. The water content can be determined by loss on drying (LOD).

[0083] Table 2

[0084] As mentioned above, reconstituted tobacco pulp contains glycerol and other substances, which can cause physical problems such as stickiness and clumping when treated with pH-adjusting solutions. Therefore, the moisture threshold for pH-adjusting solution treatment should not be too high for reconstituted tobacco pulp.

[0085] Under conditions where the moisture threshold is limited, in order to increase the pH value and maximize treatment with the pH-adjusting solution, the moisture content of the reconstituted tobacco pulp needs to be minimized before pH-adjusting solution treatment. Referring to Table 2, the moisture content before pH-adjusting solution treatment was uniformly 3% by weight under all experimental conditions.

[0086] Experimental condition 1 was designed as follows: considering the physical property issues arising from treatment with pH-adjusting solution, the moisture threshold of the reconstituted tobacco pulp was set to 7% by weight, thus achieving a moisture content of 7% by weight when treated with pH-adjusting solution. Under these conditions, the amount of potassium carbonate added relative to the tobacco powder was 5.8% by weight.

[0087] Experimental condition 2 was designed as follows: considering that the amount of potassium carbonate added relative to tobacco powder is directly proportional to the pH value of reconstituted tobacco leaves, compared with experimental condition 1, treatment with a pH adjusting solution was used to further increase the pH value, with the amount of potassium carbonate added reaching 8% by weight relative to tobacco powder. The results showed that the water content after treatment with the pH adjusting agent reached 8.6% by weight. This means that a large amount of water was injected into the pulp reconstituted tobacco leaves, leading to problems such as stickiness and clumping.

[0088] Experimental condition 3 was designed as follows: compared to experimental condition 2, the amount of water was reduced and the moisture threshold was set to 7% by weight. Treatment was performed with a pH-adjusted solution, and the amount of potassium carbonate added reached 8% by weight relative to the tobacco powder. Under these conditions, the solubility of potassium carbonate in water became a concern.

[0089] At room temperature (25℃), the solubility of potassium carbonate in water is approximately 112 g / 100 mL. In experimental conditions 1 and 2, a pH-adjusting solution was used to maximize the solubility of potassium carbonate in water at room temperature. However, as shown in experimental condition 3, if the water content is 7% by weight and the amount of potassium carbonate added reaches 8% by weight, theoretically, an aqueous solution of potassium carbonate (pH-adjusting solution) with approximately 158 g / 100 mL of dissolved potassium carbonate in water at room temperature would be required. Since this pH-adjusting solution exceeds the solubility of potassium carbonate in water (112 g / 100 mL), it cannot be prepared. Therefore, experimental condition 3 is not feasible.

[0090] Table 3 below shows the moisture content (in weight %) relative to the total weight of the paper-type reconstituted tobacco leaves and the amount of potassium carbonate added (in weight %) relative to the tobacco concentrate of the paper-type reconstituted tobacco leaves before and after treatment with the pH-adjusting solution. The paper-type reconstituted tobacco leaves may contain 88% by weight of tobacco concentrate and 12% by weight of pulp relative to the total weight of the paper-type reconstituted tobacco leaves. That is, the paper-type reconstituted tobacco leaves may be treated with a tobacco concentrate containing 88% by weight of tobacco concentrate and 12% by weight of pulp relative to the total weight of the paper-type reconstituted tobacco leaves. In this case, the tobacco concentrate may be made from a mixture of burley tobacco leaves and flue-cured tobacco leaves in a 6:4 ratio. However, the tobacco concentrate is not limited to this and may also be generated from tobacco scraps, stems, and / or tobacco processing. Additionally, the tobacco concentrate may be made from pulverized tobacco leaves, pulverized reconstituted tobacco, etc. Furthermore, the tobacco concentrate may be made from at least one type of tobacco powder selected from flue-cured tobacco, burley tobacco, flambéed tobacco, sun-cured tobacco, and air-cured tobacco. pH-adjusting solutions are mixtures of water and potassium carbonate, and can refer to aqueous solutions of potassium carbonate. The water content can be determined by the loss on drying.

[0091] Table 3

[0092] Because paper-based reconstituted tobacco does not contain glycerin, it is less sticky or clump-forming than pulp-based reconstituted tobacco and is relatively drier. Therefore, the moisture threshold can be set to a relatively high value.

[0093] In experimental conditions 4 to 7, the water content before treatment with the pH-adjusting solution was uniformly set at 3% by weight, and the treatment was carried out at room temperature with a pH-adjusting solution in which potassium carbonate was maximally soluble in water (approximately 112 g / 100 mL).

[0094] Experimental condition 4 was designed as follows: as shown in Experimental condition 1 in Table 2, the moisture threshold of the paper-type reconstituted tobacco was set to 7% by weight, thus achieving a moisture content of 7% by weight when treated with the pH-adjusting solution. Under this condition, the amount of potassium carbonate added was 5.8% by weight relative to the tobacco concentrate.

[0095] Experimental condition 5 was designed as follows: considering the physical property issues arising from treatment with pH-adjusted solutions, the moisture threshold of the paper-type reconstituted tobacco was set to 10.5% by weight, thus achieving a moisture content of 10.5% by weight when treated with the pH-adjusted solution. Under this condition, no water-based stickiness or clumping issues occurred in the paper-type reconstituted tobacco. Under this condition, the amount of potassium carbonate added relative to the tobacco concentrate was 11.1% by weight, which was relatively increased compared to experimental condition 1 in Table 2 and experimental condition 4 in Table 3.

[0096] Experimental condition 6 was designed to set the moisture threshold of the paper-based reconstituted tobacco leaves at 12% by weight, thereby achieving a moisture content of 12% by weight when treated with the pH-adjusted solution. Under this condition, the amount of potassium carbonate added relative to the tobacco concentrate was 13.2% by weight, which was relatively increased compared to experimental condition 5. However, the viscosity increased compared to experimental condition 5, but this did not cause any problems.

[0097] Experimental condition 7 was designed to set the moisture threshold of the paper-based reconstituted tobacco leaves to 14% by weight, thereby achieving a moisture content of 14% by weight when treated with the pH-adjusting solution. Under this condition, the amount of potassium carbonate added was 15% by weight relative to the tobacco concentrate. Compared with experimental condition 6, the amount of potassium carbonate added was relatively increased, but problems such as stickiness and clumping occurred.

[0098] In summary, the amount of potassium carbonate added relative to tobacco concentrate is directly proportional to the amount of pH-adjustable solution that can be processed and the pH value of reconstituted tobacco. Therefore, as shown in Tables 2 and 3, paper-based reconstituted tobacco has a higher pH value than pulp-based reconstituted tobacco, and thus the aerosol-generated articles made using paper-based reconstituted tobacco have a higher nicotine delivery.

[0099] In addition, even when paper-based reconstituted tobacco is used to manufacture aerosol-generating products, an appropriate amount of pH-adjusting solution is needed to prevent problems such as stickiness and clumping between the paper-based reconstituted tobacco leaves.

[0100] On the other hand, when the pH value of the tobacco medium is high, nicotine continues to be released from the tobacco medium during the unused storage of the aerosol-generating article 2, thereby reducing the actual amount of nicotine delivered when the aerosol-generating article 2 is used subsequently. Additionally, if the pH value of the tobacco medium is too high, an off-odor may be generated in the aerosol-generating article 2, thus affecting the user's smoking experience.

[0101] When the aerosol generating article 2 is a non-heated aerosol generating article, when the pH value of the tobacco medium is about 7 to about 10, or about 8 to about 9, the delivery of nicotine and the user's smoking satisfaction can be improved.

[0102] Table 4 below shows the relationship between the amount of potassium carbonate added (in weight %) relative to the pH value of the tobacco concentrate in papermaking reconstituted tobacco.

[0103] Table 4

[0104] Referring to Table 4, it can be seen that the pH value increases with the increase of potassium carbonate addition. As mentioned above, even if the pH value is too high, the nicotine delivery will decrease and affect the smoking experience. Therefore, for sufficient nicotine delivery, the appropriate pH range needs to be considered when adjusting the amount of potassium carbonate added.

[0105] In one embodiment, the media section 220 may include at least one of an acetate filter formed from cellulose acetate tow and a paper filter formed from paper.

[0106] For example, when the media section 220 includes at least one of an acetic acid filter and a paper filter, the interior of the filter may be filled with tobacco media. In this case, the tobacco media may be filled to a density of about 2 mg / mm to about 8 mg / mm inside the filter. Alternatively, the tobacco media may be filled to a density of about 4 mg / mm to about 6 mg / mm inside the filter.

[0107] When the pH of the tobacco medium contained in the medium section 220 is adjusted to alkaline by a pH adjusting solution, the amount of nicotine released from the tobacco medium can be increased under low temperature conditions. Therefore, when the medium section 220 is manufactured by filling it with pH-adjusted tobacco medium, either the acetic acid filter or the paper filter can maintain its absorption of nicotine released from the tobacco medium, thus preventing the released nicotine from being released to the outside of the aerosol-generating article 2.

[0108] The media section 220 may include a first segment and a second segment. During the manufacturing process of the media section 220, the first and second segments are manufactured independently; therefore, the first and second segments are interconnected but distinguishable. The first segment may be adjacent to the front-end insert 210, and the second segment may be adjacent to the filter section 230. For both segments, refer to... Figures 5a to 5c This will be discussed later.

[0109] In one embodiment, the filter section 230 may be positioned opposite to the front-end insert 210, with the medium section 220 as the center. The filter section 230 can filter at least one of the substances contained in the mainstream smoke, including the aerosol generated by the medium section 220.

[0110] In one embodiment, the filter section 230 can be of various shapes. For example, the filter section 230 can be a cylindrical rod or a hollow tubular rod. Alternatively, the filter section 230 can also be a recessed rod.

[0111] In one embodiment, the filter section 230 may include either an acetate filter formed from cellulose acetate filaments or a paper tube filter formed from paper. In this case, when the filter section 230 includes an acetate filter formed from cellulose acetate filaments, the filter section 230 can be configured to produce a fragrance.

[0112] For example, when the filter section 230 includes an acetic acid filter, a fragrance liquid containing a flavoring substance can be sprayed onto the acetic acid filter, and individual fibers coated with the fragrance liquid can be included inside the acetic acid filter. As another example, when the filter section 230 includes an acetic acid filter, the acetic acid filter may also include a capsule containing a flavoring substance. The flavoring substance that may be included in the filter section 230 may be the same as or similar to the flavoring substance that may be included in the front-end insert 210.

[0113] In one embodiment, one of the front-end plug 210 and the filter section 230 may contain a fragrance substance.

[0114] For example, when the front-end plug 210 includes a capsule containing a fragrance substance or fibers coated with a fragrance liquid containing a fragrance substance, the filter section 230 may not contain a fragrance substance. That is, if the front-end plug 210 contains a fragrance substance, the filter section 230 may include an embedded rod formed of cellulose acetate tow, or it may include a paper tube formed of paper.

[0115] For example, when the filter section 230 includes a capsule containing a fragrance substance or fibers coated with a fragrance liquid containing a fragrance substance, the front insert 210 may not contain a fragrance substance. That is, if the filter section 230 contains a fragrance substance, the front insert 210 may include an acetate filter formed of cellulose acetate tow, or it may include a paper tube formed of paper.

[0116] The aerosol generating article 2 can be made into a cylindrical shape. In one embodiment, when the aerosol generating article 2 is made into a cylindrical shape, its length can be from about 24 mm to about 72 mm. For example, the length of the front-end insert 210 can be from about 6 mm to about 18 mm, the length of the medium section 220 can be from about 12 mm to about 36 mm, and the length of the filter section 230 can be from about 6 mm to about 18 mm. However, the length of the aerosol generating article 2 and the components constituting it is not limited to this and can be varied in various ways according to the manufacturer's design.

[0117] The two sections of the medium section 220 will be described below.

[0118] Figures 5a to 5c It is Figure 4 The image shows a cross-sectional view of an aerosol-generating article cut along its length and viewed in the X-X' direction.

[0119] Reference Figures 5a to 5c In one embodiment, the aerosol-generating article 2 may include a front-end insert 210, a medium section 220, and a filter section 230. As shown in the drawings, the front-end insert 210 includes a paper filter (e.g., a paper tube) formed of paper, and the filter section 230 includes an acetic acid filter, which includes, but is not limited to, a capsule 232 containing a flavoring substance. In another embodiment, the front-end insert 210 may include an acetic acid filter, which includes a capsule 232 containing a flavoring substance, and the filter section 230 may also include an embedded rod formed of cellulose acetate tow.

[0120] In one embodiment, the medium section 220 of the aerosol-generating article 2 may include two segments, each comprising different elements. For example, the first segment 240 of the medium section 220 may include a tobacco medium 222 made from paper-based reconstituted tobacco, and the second segment 250 may include a cooling element 226. In this case, the cooling element 226 may correspond to either a tubular filter or a paper tube filter, and the inhalation resistance of the aerosol-generating article 2 may be reduced by the cooling element 226.

[0121] Reference Figure 5a The first segment 240 of the tobacco medium 222 can be configured in partition A of the medium section 220 (e.g., Figure 4 In partition A of the medium section 220, the second segment 250, including the cooling element 226, can be configured in partition B of the medium section 220 (e.g., Figure 4 In partition B of the middle.

[0122] That is, after the external air introduced through the front-end plug 210 is mixed with the nicotine and other components released in the tobacco medium 222 of the first section 240, it can pass through the second section 250 and the filter section 230 in sequence.

[0123] Reference Figure 5b The second section 250, including the cooling element 226, can be disposed in partition A of the media section 220, and the first section 240, including the tobacco media 222, can be disposed in partition B of the media section 220. That is, the external air introduced through the front-end plug 210 is cooled by the cooling element 226 of the second section 250, and then passes through the first section 240 and the filter section 230 in sequence.

[0124] In another embodiment, the medium portion 220 may include two segments comprising the same elements. For example, the first segment 240a and the second segment 240b of the medium portion 220 may each comprise tobacco medium 222.

[0125] Reference Figure 5c The first segment 240a of the tobacco medium 222 may be disposed in partition A of the medium section 220, and the second segment 240b of the tobacco medium 222 may be disposed in partition B of the medium section 220.

[0126] In one embodiment, the first segment 240a can be made by filling an acetic acid filter with tobacco medium 222, and the second segment 240b can be made by filling a paper filter with tobacco medium 222.

[0127] However, this is only one embodiment and is not limited thereto. In another embodiment, the first segment 240a can be made by filling a paper filter with tobacco medium 222, and the second segment 240b can also be made by filling an acetic acid filter with tobacco medium 222. Alternatively, both the first segment 240a and the second segment 240b can be made by filling an acetic acid filter with tobacco medium 222, or by filling a paper filter.

[0128] Table 5 below is the analysis Figures 5a to 5c The data shown in the figure represent the mainstream smoke (e.g., aerosol) composition of the aerosol generating article 2. At this time, the medium section 220 of the aerosol generating article 2 includes a tobacco medium 222 made of paper-type recycled tobacco leaves.

[0129] Table 5

[0130] The experiment was conducted as follows: Following the smoking conditions of the International Organization for Standardization (ISO), a total of 20 aerosol-generating items were inhaled using an automatic smoking machine, and the mainstream smoke was captured in a Cambridge filter. After smoking, the total particulate matter (TPM) captured on the Cambridge filter was extracted with isopropyl alcohol, and the nicotine content was determined.

[0131] The tobacco end (TE) described in Table 5 can refer to the distal end of the aerosol-generating article or the end inserted into the aerosol-generating device. The mouth end (ME) can refer to the proximal end of the aerosol-generating article or the end that contacts the user's mouth.

[0132] Experimental results show that, compared to the case where tobacco medium 222 is applied to a segment (e.g., Figure 5a and Figure 5bIn contrast, when tobacco medium 222 is applied to two segments (e.g., Figure 5c Under these conditions, the nicotine delivery and nicotine transfer are higher. In particular, it can be seen that the nicotine delivery and nicotine transfer are greater than the total particulate matter value showing the amount of vaporization. This is a result of the tobacco medium 222 being used more extensively in the medium section 220.

[0133] Figure 6 This is a flowchart illustrating a method for manufacturing tobacco media according to an embodiment.

[0134] Reference Figure 6 The process of manufacturing tobacco media from paper-based reconstituted tobacco leaves is shown in chronological order.

[0135] In step S610, the manufacture of the tobacco medium may begin with the step of providing paper-type reconstituted tobacco leaves. The paper-type reconstituted tobacco leaves may be made through the following process.

[0136] First, the tobacco leaves are heated to a high temperature. Then, the liquid tobacco components are separated (concentrating them to create a tobacco concentrate), leaving a solid component without tobacco. This solid component is dried to form a paper-like substance. This paper is called "base paper." The tobacco concentrate obtained in the previous step, after separating and concentrating the liquid tobacco components, can be mixed with pulp to create a tobacco concentrate. For example, the tobacco concentrate may contain 88% by weight of tobacco concentrate and 12% by weight of pulp relative to its total weight.

[0137] Tobacco concentrate is sprayed and coated onto base paper. The base paper coated with tobacco concentrate is then processed into sheets, and the sheets are dried at high temperature to produce paper-based reconstituted tobacco. At this point, based on the total weight of the base paper, the content of tobacco concentrate in the paper-based reconstituted tobacco can be 30% to 40% by weight.

[0138] In step S620, a first flavoring treatment step can be performed to treat the papermaking reconstituted tobacco leaves with a first flavoring substance. At this time, the first flavoring substance may contain a humectant. Furthermore, the first flavoring substance may contain plant-based fragrances, animal-based fragrances, alcohol compounds, aldehyde compounds, ester compounds, and combinations thereof, as described above.

[0139] The first flavoring process imparts flexibility and moisture retention to reconstituted tobacco leaves and enhances the inherent flavor of the tobacco. This first flavoring process can be performed before the paper-based reconstituted tobacco leaves are cut and become the finished product. During the manufacture of tobacco media, the first flavoring process can improve workability.

[0140] In step S630, the papermaking reconstituted tobacco leaves that have undergone the first flavoring treatment can be dried. During this process, a portion of the first flavoring substance may volatilize. To compensate for the loss of flavor due to the volatilization of the flavoring substance, a second flavoring treatment can be performed subsequently.

[0141] In step S640, the dried paper-type reconstituted tobacco leaves can be cut. The cut paper-type reconstituted tobacco leaves can be considered as finished products. Cutting the paper-type reconstituted tobacco leaves before the second flavoring treatment can improve the effect of the secondary flavoring.

[0142] In step S650, the papermaking reconstituted tobacco leaves may be treated with a pH-adjusting solution. This pH-adjusting solution treatment may be performed together with or separately from the secondary flavoring treatment described later. For example, the pH-adjusting solution may contain potassium carbonate and water. In this case, the potassium carbonate is maximally dissolved in water, based on its solubility, to prepare the pH-adjusting solution.

[0143] The step of treating with a pH-adjusting solution may include the following process: spraying the pH-adjusting solution onto the paper-forming reconstituted tobacco leaves at a rate of 1 L per minute for 5 minutes, and mixing the paper-forming reconstituted tobacco leaves to ensure that the pH-adjusting solution can uniformly contact the paper-forming reconstituted tobacco leaves. During this time, the ambient temperature can be maintained between 20°C and 30°C, or at room temperature (25°C).

[0144] Relative to the total weight of the paper-based reconstituted tobacco leaves, the leaves can be treated with a pH-adjusting solution until the moisture content reaches 9% to 12% by weight, 10% to 11% by weight, or 10.5% by weight. Results show that the final moisture content of the tobacco medium can reach 9% to 12% by weight, 10% to 11% by weight, or 10.5% by weight. Setting the moisture content in this way prevents the paper-based reconstituted tobacco leaves from clumping and increases the pH value of the tobacco medium.

[0145] Furthermore, the amount of potassium carbonate added relative to the total weight of tobacco concentrate contained in paper-based reconstituted tobacco leaves can be 8% to 14% by weight, or 10% to 12% by weight, or 10.5% to 11.5% by weight, or 11.1% by weight. By setting the amount of potassium carbonate added relative to the total weight of tobacco concentrate in this way, the pH value of the tobacco medium can be prevented from rising outside the appropriate range. This prevents the reduction in nicotine delivery and the decrease in smoking sensation caused by an increase in pH value.

[0146] On the other hand, in step S650, the second flavoring treatment step, which involves treating the cut finished paper-type reconstituted tobacco leaves with a second flavoring substance different from the first flavoring substance, can be performed together with the step of treating with a pH-adjusting solution. The second flavoring substance may include any one of the plant-based fragrances, animal-based fragrances, alcohol compounds, aldehyde compounds, and ester compounds as described above. Alternatively, the second flavoring substance may consist only of any one of the fragrances and compounds listed above. The two flavoring treatments may be omitted according to the embodiment.

[0147] Furthermore, the method for manufacturing the tobacco medium according to the embodiment can increase the nicotine delivery of aerosol-generated articles using the tobacco medium.

[0148] Furthermore, the method for manufacturing tobacco media according to the embodiments can reduce the cost of manufacturing tobacco media.

[0149] The embodiments of the present invention described above, or other embodiments thereof, are not mutually exclusive or distinct. In the embodiments of the present invention described above, various components or functions may be combined or used in combination with each other.

[0150] For example, configuration A described in a particular embodiment and / or drawing can be combined with configuration B described in other embodiments and / or drawings. That is, combinations can be made even if the combination between configurations is not directly described, unless described as impossible.

[0151] The above specific description should not be construed as limiting in all respects, but should be regarded as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
