1 is a flowchart exemplarily illustrating a method for manufacturing a plate-like sheet according to some embodiments of the present invention.

Referring to Figure 1, the manufacturing method of the leaf sheet includes the steps of selecting a tobacco material (S10), pulverizing the selected tobacco material (S20), pulverized tobacco material and propylene glycol (Propylene Glycol) and glycerin (Glycerin) A step of preparing a slurry by mixing (S30), manufacturing a plate-leaf sheet using a slurry in which tobacco material, propylene glycol, and glycerin are mixed (S40) and processing the plate-leaf sheet (S50) can do.

In the step (S10) of selecting the tobacco material, the tobacco material may include at least one tobacco species of xantho, Bury, Orient, and Cigar species. For example, the tobacco material may comprise from about 0% to 20% xanthium, from about 0% to 50% burry species and from about 0% to 30% orient species, by total weight of the tobacco material, Of course, the present invention is not limited thereto.

The tobacco material may also include filler tobacco. A filler tobacco herein may refer to a tobacco that is not a specific tobacco type, but is primarily used to supplement other tobacco types used in the formulation and does not induce a specific characteristic aroma aroma in the final product. Filler tobacco can be obtained from stems, stems or petioles.

In the step of pulverizing the selected tobacco material (S20), the selected tobacco material may be pulverized to a particle size suitable for forming a slurry. For example, ground tobacco material, ie, tobacco powder, may have an average particle size of about 0.03 mm to about 0.12 mm, but is not limited thereto.

The step of preparing a slurry by mixing the pulverized tobacco material with propylene glycol and glycerin (S30) is a process of mixing the pulverized tobacco material with a binder such as guar gum and gum arabic, and transferring the mixed solution to a slurry mixing tank process, transferring the pulp to a slurry mixing tank, and the like. In addition, for preparing the slurry, the pulverized tobacco material may be administered to a slurry mixing tank containing pulp and a humectant. Here, the slurry may be processed by a high shear mixer to ensure uniformity and homogeneity of the slurry. Water can also be added to the slurry to achieve the desired viscosity and moisture.

Meanwhile, the weight of the moisturizer in the slurry (eg, the combined weight of propylene glycol and glycerin) may be approximately 20% to 30% based on the total weight of the slurry. That is, the humectant may be casing as part of the primary flavoring in the slurry. For example, the slurry may consist of about 65% by weight of ground tobacco material, about 25% by weight of propylene glycol and glycerin, about 5% by weight of guar gum, and about 5% by weight of pulp, but is not limited thereto.

In some embodiments, the weight of propylene glycol included in the slurry may be 3% to 13% based on the total weight of the slurry, and the weight of glycerin may be 7% to 27% based on the total weight of the slurry. Preferably, the weight of propylene glycol contained in the slurry may be 3% to 10% based on the total weight of the slurry, and the weight of glycerin may be 12% to 22% based on the total weight of the slurry. More preferably, the weight of propylene glycol included in the slurry is 3% to 7% (eg about 5%) relative to the total weight of the slurry, and the weight of glycerin is 18% to 22% (eg, about 5%) relative to the total weight of the slurry. For example, about 20%).

On the other hand, as will be described later, in the plate-leaf sheet processed in the processing step (S50) of the plate-leaf sheet (eg, a plurality of plate-leaf strands), propylene glycol is additionally added (eg, For example, about 0.1% to 5%) relative to the total weight of the processed platelet sheet) may be added, and in this case, propylene glycol and glycerin in the slurry may be added in consideration of sensory characteristics such as taste and taste durability of non-combustible smoking articles. The weight ratio may be different.

Specifically, in the slurry preparation step (S30), the weight of propylene glycol contained in the slurry is 8% to 12% (eg, about 10%) relative to the total weight of the slurry, and the weight of glycerin is 13 compared to the total weight of the slurry % to 17% (eg, about 15%). In this case, in the secondary flavoring step performed after the processing step (S50) of the plate-leaf sheet, the preferred weight of propylene glycol additionally added to the processed plate-leaf sheet is 1% to 2% based on the total weight of the processed plate-leaf sheet (eg, about 1.5%).

When propylene glycol exceeding the above numerical range is used in the slurry for the production of leaf sheets, the amount of atomization of the manufactured non-combustible smoking article is reduced. Flavors such as burnt taste and steamed taste become stronger due to heating. On the other hand, when propylene glycol and glycerin in the same weight ratio as described above are used for the preparation of the slurry, even when the finished non-combustible smoking article is heated to a temperature suitable for smoking, the occurrence of odors such as burnt taste and steamy taste is reduced, and from the initial stage of smoking It is also possible to maintain a lasting tobacco taste until the second half.

On the other hand, in some embodiments for increasing the amount of nicotine transfer, the slurry may additionally include at least one basic material selected from among potassium carbonate, potassium bicarbonate, sodium carbonate, sodium hydrogen carbonate, and calcium carbonate. The basic material may be added such that the slurry has a pH of 7 to 10, preferably 7.0 to 9.0, more preferably 7.5 to 9.5, but is not limited thereto.

The step (S40) of manufacturing a plate leaf sheet using the slurry in which the tobacco material, propylene glycol, and glycerin are mixed may include a process of casting the mixed slurry and a process of drying the cast slurry, and thus A plate-like sheet having a homogeneous and uniform thickness can be manufactured. Here, the plate-like sheet may be manufactured to have a thickness of approximately 0.1 mm to 1.5 mm.

On the other hand, the plate-like sheet prepared in this way is a tobacco raw material comprising at least one of xanth, burry, orient, and cigar; glycerin and propylene glycol; a binder comprising at least one of guar gum and gum arabic; and cellulosic pulp.

The manufactured plate leaf sheet may be processed into a form to be filled in each non-combustible smoking article (S50). For example, the processed platelet sheet may be a plurality of engraved platelet sheets or a plurality of platelet strands (ie, in the form of cut filler).

For example, the platelet sheet can be processed into a plurality of engraved platelet sheets having a width of approximately 1 mm to 6 mm (eg 5 mm) and a length of approximately 8 mm to 17 mm (eg 15 mm). . Alternatively, the platelet sheet may be processed into a plurality of platelet cut fillers having a width of about 0.8mm to 1.2mm (eg, 1mm) and a length of about 10mm to 14mm (eg, 12mm).

On the other hand, although not shown in FIG. 1, in some embodiments, after the processing step (S50) of the plate leaf sheet, a secondary flavoring process for further enhancing the taste and flavor of cigarettes and imparting a characteristic flavor for each product group is processed. It may also be performed in addition to the lamellar sheet. In this case, in the method of manufacturing a plate leaf sheet according to some embodiments of the present invention, propylene glycol may be additionally added in addition to the perfume materials used in the secondary flavoring process. For example, the weight of propylene glycol additionally added to the plate leaf sheet processed in the secondary flavoring process may be about 0.1% to 5% (preferably, 1% to 2%) based on the total weight of the plate leaf sheet processed. have.

The battery 1100 supplies power used to operate the aerosol generating device 1000 . For example, the battery 1100 may supply power to the heater 1300 or the vaporizer 1400 to be heated, and may supply power required for the control unit 1200 to operate. In addition, the battery 1100 may supply power required to operate a display, a sensor, a motor, etc. (not shown) installed in the aerosol generating device 1000 .

The controller 1200 may control the overall operation of the aerosol generating device 1000 . Specifically, the controller 1200 may control the operation of the battery 1100 , the heater 1300 , and the vaporizer 1400 , as well as other components that may be included in the aerosol generating device 1000 . In addition, the controller 1200 may determine whether the aerosol generating device 1000 is in an operable state by checking the state of each of the components of the aerosol generating device 1000 .

The controller 1200 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, it can be understood by those skilled in the art that the present embodiment may be implemented in other types of hardware.

The heater 1300 may be heated by power supplied from the battery 1100 . For example, when a cigarette is inserted into the aerosol-generating device 1000 , the heater 1300 is inserted into a partial region inside the cigarette 2000 , and the heated heater 1300 is the temperature of the aerosol-generating material in the cigarette 2000 . can raise

The heater 1300 may be an electrically resistive heater. For example, the heater 1300 may include an electrically conductive track, and the heater 1300 may be heated as current flows through the electrically conductive track. However, the heater 1300 is not limited to the above-described example, and may be applicable without limitation as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 1000 or may be set to a desired temperature by the user.

In other words, the aerosol generated by the vaporizer 1400 may move along the airflow path of the aerosol generating device 1000, and the airflow path passes the aerosol generated by the vaporizer 1400 through the cigarette to the user. It can be configured to be For example, the vaporizer 1400 may include, but is not limited to, a liquid reservoir, a liquid delivery means, and a heating element. For example, the liquid reservoir, liquid delivery means and heating element may be included in the aerosol generating device 1000 as independent modules.

The liquid reservoir may store the liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing material comprising a volatile tobacco flavor component, or may be a liquid comprising a non-tobacco material. The liquid storage unit may be manufactured to be detachable/attached from the vaporizer 1400 , or may be manufactured integrally with the vaporizer 1400 .

The liquid delivery means may deliver the liquid composition of the liquid reservoir to the heating element. For example, the liquid delivery means may be, but is not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

The heating element is an element for heating the liquid composition delivered by the liquid delivery means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, or the like. In addition, the heating element may be composed of a conductive filament, such as a nichrome wire, and may be arranged to be wound around the liquid delivery means.

The heating element may be heated by supplying an electrical current, and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated.

For example, the vaporizer 1400 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

Meanwhile, the aerosol generating device 1000 may further include general-purpose components in addition to the battery 1100 , the controller 1200 , the heater 1300 , and the vaporizer 1400 . For example, the aerosol generating device 1000 may include a display capable of outputting visual information and/or a motor for outputting tactile information. In addition, the aerosol generating device 1000 may include at least one sensor (a puff detection sensor, a temperature sensor, a cigarette insertion detection sensor, etc.). In addition, the aerosol generating device 1000 may be manufactured in a structure in which external air may be introduced or internal gas may flow out even in a state in which the cigarette 2000 is inserted.

For example, the cradle may be used to charge the battery 1100 of the aerosol generating device 1000 . Alternatively, the heater 1300 may be heated in a state in which the cradle and the aerosol generating device 1000 are coupled.

The cigarette 2000 may be divided into a first part including an aerosol generating material and a second part including a filter and the like. Alternatively, the second portion of the cigarette 2000 may also include an aerosol generating material. For example, an aerosol-generating material made in the form of granules or capsules may be inserted into the second part.

The entire first portion of the cigarette 2000 may be inserted into the aerosol generating device 1000 , and the second portion of the cigarette 2000 may be exposed to the outside.

Example 1

A non-combustible smoking article was prepared in the same manner as in Comparative Example 1, except that the leaf sheet used in the smoking material rod part was prepared using a slurry containing propylene glycol. Specifically, the platelet sheet used was prepared using a slurry containing about 5% by weight of propylene glycol and about 20% by weight of glycerin, and then cut into a plurality of platelet strands.

Example 2

A non-combustible smoking article was prepared in the same manner as in Example 1, except that propylene glycol was additionally added to the cut platelet strands. Specifically, about 1.5% of propylene glycol was additionally added to the cut platelet strands based on the total weight of the cut platelet strands.

Example 3

A non-combustible smoking article was prepared in the same manner as in Example 1, except that a plate-leaf sheet prepared using a slurry containing about 10% by weight of propylene glycol and about 15% by weight of glycerin was used.

Example 4

A non-combustible smoking article was prepared in the same manner as in Example 3, except that about 1.5% of propylene glycol based on the total weight of the cut platelet strands was additionally added to the cut platelet strands.

Example 5

A non-combustible smoking article was prepared in the same manner as in Example 1, except that a plate-leaf sheet prepared using a slurry containing about 15% by weight of propylene glycol and about 10% by weight of glycerin was used.

Experimental Example 1: Amount of ingredients in leaves and moisture content in leaves analyze

Tables 2 and 3 show the analysis results of the amount of component in the leaf and the content of the moisturizing agent in the leaf of the smoking articles according to Comparative Example 1 and Examples 1 to 6. Table 2 shows the components of nicotine, sugar, nitric acid and chlorine in the medium of the smoking article, and Table 3 shows the residual amounts of glycerin and propylene glycol in the medium of the smoking article.

In Table 2, referring to the results of Examples 1 to 4, the amount of nicotine component showed a tendency to increase as the amount of propylene glycol added increased, but in Examples 5 and 6, the amount of nicotine component was rather slightly decreased. In the case of total sugar, there was no significant difference between Comparative Examples and Examples, but slightly increased results were confirmed in Examples 3 and 4.

Referring to Table 3, in the case of propylene glycol, the residual amount compared to the added amount showed a tendency to generally decrease, and in the case of glycerin, there was no significant difference between the added amount and the residual amount. The change in the residual amount of moisturizer according to the addition of propylene glycol in the secondary fragrance was different depending on the amount of propylene glycol added in the primary fragrance. Specifically, Example 2 showed a significant difference in the residual amount of propylene glycol compared to Example 1, but in Examples 4 and 6, there was no significant difference in the residual amount of propylene glycol compared to Examples 3 and 5.

Experimental Example 2: Smoke component analysis

In order to analyze the smoke components of the smoking articles according to Comparative Example 1 and Examples 1 to 6, the smoke components of mainstream smoke during smoking of the smoking articles 2 weeks after manufacture were analyzed. The smoke collection for component analysis was repeated 4 times for each sample and 8 puffs for each time, and the component analysis results based on the average value of the collection results for 3 times are shown in Table 4. Cigarettes were tested according to HC (Health Canada) smoking conditions using a non-combustible automatic smoking device in a smoking room with a temperature of approximately 20° C. and a humidity of approximately 62.5%.

Referring to Table 4, in Examples 1 to 6 in which propylene glycol was added to the slurry for preparing the platelet and/or to the cut platelet pieces, compared to Comparative Example 1, total particle materials (TPM), nicotine and moisture were There was a tendency to decrease slightly, and a tendency to slightly increase in tar. In addition, looking at the results of Examples 1 to 6, as the amount of propylene glycol added increased, there was a tendency that the amount of tar transfer generally increased. No significant change was observed in the amount of nicotine transfer according to the amount of propylene glycol added.

On the other hand, in Examples 5 and 6, compared to Comparative Example 1 and other Examples, a significantly greater decrease in moisture in the smoke and a decrease in the amount of glycerin transfer were observed, and accordingly, a decrease in the amount of atomization and the expression of a burnt taste were expected.

Experimental Example 3: Smoking sensory evaluation according to Comparative Example 1, Example 1 and Example 5

Comparative Example 1 using a slurry containing 25% glycerin, Example 1 using a slurry containing 5% propylene glycol and 20% glycerin, and Example 1 using a slurry containing 15% propylene glycol and 10% glycerin The smoking articles of 5 were subjected to sensory evaluation during smoking using the aerosol generating device 1000 . Sensory characteristics evaluation was conducted for a total of 19 evaluation panel members, and a total of 7 points was used as the standard.

9 is an evaluation result of sensory characteristics of smoking articles according to Comparative Example 1, Example 1, and Example 5; Referring to FIG. 9 , no significant difference was observed for taste intensity characteristics between Examples and Comparative Examples, but differences between Examples and Comparative Examples were observed in all of the atomization amount, taste, irritation, taste/scent consistency, and clean aftertaste characteristics.

Specifically, in the case of Example 1, it can be seen that the same level of taste and atomization characteristics as those of Comparative Example 1 were exhibited, but taste/scent consistency and clean aftertaste were increased, and at the same time, taste and irritation were significantly reduced.

On the other hand, in Example 5, rather than in Comparative Example 1, the taste increased, and the amount of atomization and the consistency of taste/scent were significantly reduced, which, as in Example 5, contained propylene glycol or more and glycerin was less than the reference value, as in Example 5. It is expected that the amount of moisture or glycerin transfer throughout the year decreases according to the deterioration of the moisturizing properties, and the carbonization problem of smoking materials occurs.

A person of ordinary skill in the art related to this embodiment will understand that it can be implemented in a modified form without departing from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
