In addition, the smoking article may contain solid materials based on tobacco raw materials, such as leaf tobacco, cut filler, reconstituted tobacco, and the like. Smoking materials may contain volatile compounds.

1 is a flowchart exemplarily illustrating a method of manufacturing a smoking article according to some embodiments of the present invention.

Referring to FIG. 1 , the method for manufacturing a non-combustible smoking article includes the steps of injecting a smoking material into a roasting container (S10), sealing the roasting container and then heating to roast the smoking material (S20), and naturally cooling the roasting container. After that, it may include the steps of opening the sealed roasting container (S30) and manufacturing a non-combustible smoking article using the roasted smoking material (S40).

In the step (S10) of injecting the smoking material into the roasting container, an inner space capable of accommodating the smoking material is provided inside the roasting container, and the inner space may be configured to be sealed in the roasting step (S20). .

On the other hand, when the roasting step is performed in a dry roasting method, no solvent is present in the roasting container. In contrast, when the roasting step is performed in a wet roasting method, a solvent is provided in the roasting container, and the smoking material is put into the solvent to be roasted.

When the roasting step is performed in a wet roasting method, the solvent may be a liquid having a boiling point of approximately 200°C to 500°C. In some embodiments, the solvent may have a higher boiling point than the temperature inside the roasting container in the roasting step (S20). The solvent may be, for example, glycerol.

On the other hand, the roasting container may include a cooling space in fluid communication with the inner space in which the smoking material is accommodated. The cooling space may be cooled by a cooling device in which a cooling material composed of water, a solvent having an alcohol functional group, an oil such as oil, or a mixture thereof is circulated therein.

Meanwhile, the inside of the cooling device through which the cooling material is circulated may not be in fluid communication with the internal space of the roasting container and the cooling space.

In this case, the cooling space is cooled by the cooling material, and accordingly, at least a portion of the flavor component released into the gas phase by heating the smoking material is cooled by the cooling material in the cooling space and being roasted or roasted. It may be reduced to smoking material. In other words, the flavor component released from the smoking material may not be directly captured by the cooling material, but may simply serve to cool the gas containing the flavor component released. In other words, in the reduction of the released flavor component, the cooling material may not serve as a solvent for collecting the released flavor component.

Meanwhile, the temperature of the cooling material may be approximately -100°C to 80°C. Preferably, the temperature of the cooling material may be approximately -50 °C to 80 °C. More preferably, the temperature of the cooling material may be approximately -20°C to 40°C.

The smoking material in the roasting step (S20) may be a tobacco raw material that is not physically processed, or may be a smoking material that is physically processed as a medium finally used for smoking articles. For example, the smoking material may be first roasted in a leaf tobacco state or in a leaf tobacco powder state, and then processed into a plate leaf or cut filler. Alternatively, after being first processed into a plate leaf or cut filler, the roasting process may be performed.

In some embodiments, the roasted smoking material may include tobacco raw materials, such as xanthan, burry, orient.

Meanwhile, the smoking material in the roasting step (S20) may be acidic or neutral. That is, the pH of the smoking material may be 0 or more and 7 or less. In other words, the smoking material has not been subjected to a pH adjustment process such as adding a basic material to increase the amount of nicotine transfer and taste of the smoking material.

In some embodiments, the temperature inside the roasting vessel in the roasting step (S20) may be approximately 100 ℃ to 350 ℃. Preferably, the temperature inside the roasting container in the roasting step may be approximately 150 °C to 350 °C. More preferably, the temperature inside the roasting vessel in the roasting step may be approximately 180 °C to 350 °C (eg, 250 °C).

On the other hand, the roasted smoking material may have a weight of 85% to 99% of the weight of the smoking material before the roasting step (S20). Preferably, the roasted smoking material may have a weight of 93% to 97% of the weight of the smoking material prior to roasting.

More specifically, when the roasting step is performed in a dry roasting method, in the roasting step (S20), the temperature inside the roasting container is about 200° C. to 250° C., and the temperature of the smoking material injected into the roasting container is about It may be carried out for about 2 hours to 3 hours under the conditions of 100°C to 180°C. In this case, the moisture reduction rate of the smoking material by the roasting may be 2% to 15% (preferably, 5% to 7%). That is, the roasted smoking material may have a weight of 85% to 98% (preferably, 93% to 95%) based on the weight of the smoking material before roasting.

In contrast, when the roasting step is performed in the wet roasting method, the roasting step (S20) is performed at a temperature of 200° C. to 250° C. inside the roasting container, and a temperature of the smoking material put into the roasting container at 180° C. to 250° C. It may be carried out for 3 to 4 hours under the condition of ℃. In this case, the moisture reduction rate of the smoking material by the roasting may be 2% to 15% (preferably, 3% to 5%). That is, the roasted smoking material may have a weight of 85% to 98% (preferably, 95% to 97%) based on the weight of the smoking material before roasting.

In some embodiments, the roasting step S20 may have a plurality of stages having different temperature conditions during roasting. More specifically, the roasting step (S20) includes a first roasting stage and a second roasting stage performed after the first roasting stage, wherein the first roasting stage has an internal temperature of approximately 150°C to 200°C. It is carried out for 0.5 hour to 1.5 hours under the conditions, and the second roasting stage may be performed for 1 hour to 2 hours under the condition that the temperature inside the roasting vessel is approximately 200°C to 250°C.

After the roasting step (S20), the sealed roasting container may be opened after being naturally cooled for about 3 to 6 hours at room temperature. That is, the air in the roasting container may communicate with the outside air after the natural cooling. While the sealed roasting container is naturally cooled, an appropriate amount of flavor components among the flavor components released from the smoking material into the gas phase may be reduced to the smoking material.

As the roasted smoking material is included in the medium of the non-combustible smoking article, the non-combustible smoking article can be assembled (S40). As described above, if the smoking material in the roasting step (S20) is a non-physically unprocessed tobacco raw material such as leaf tobacco or leaf tobacco powder, the roasted smoking material is processed into a plate leaf or cut filler, and then the non-combustible smoking article It can be used in manufacturing, but is not limited thereto. That is, if the smoking material in the roasting step (S20) is in a processed form such as plate leaf or cut filler, the processing step may be omitted.

Step S40 may include a process of wrapping the roasted smoking material through a smoking material wrapper, a process of combining the smoking material wrapped in the wrapper with an acetate filter, etc. through a tipping wrapper, and the like. The description will be omitted.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through Examples and Comparative Examples. However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

Comparative Example 1

For the example, a non-combustible smoking article having the same structure as that of the smoking article 300 shown in FIG. 5 manufactured for testing was manufactured. In particular, in the smoking material unit 310 (refer to FIG. 5 ), a smoking material to which a pH control (eg, addition of a basic material, etc.) process and a roasting process are not applied were used.

Example 1

A smoking article similar to that of Comparative Example 1 was prepared, except that roasted smoking material was used in the smoking material part. The roasting of the smoking material was carried out in a dry roasting method, and the temperature inside the roasting container was 100° C. to 150° C., and the temperature of the smoking material put into the roasting container was 50° C. to 100° C. It was carried out for about 2.5 hours.

Example 2

The same smoking article as in Example 1 was prepared except that the roasting was performed for about 5 hours. That is, the roasting of the smoking material was carried out for about 5 hours under the condition that the temperature inside the roasting container was 100° C. to 150° C. and the temperature of the smoking material put into the roasting container was 50° C. to 100° C.

Example 3

Smoking articles were prepared in the same manner as in Example 1 except for the roasting temperature conditions. The roasting of the smoking material was carried out for about 2.5 hours under the condition that the temperature inside the roasting container was 200°C to 250°C and the temperature of the smoking material put into the roasting container was 100°C to 180°C.

Example 4

The same smoking article as in Example 3 was prepared except that the roasting was performed for about 5 hours. That is, the roasting of the smoking material was carried out for about 5 hours under the condition that the temperature inside the roasting container was 200°C to 250°C and the temperature of the smoking material put into the roasting container was 100°C to 180°C.

Example 5

Smoking articles were prepared in the same manner as in Example 1 except for the roasting temperature conditions. The roasting of the smoking material was carried out for about 2.5 hours under the condition that the temperature inside the roasting container was 350° C. to 400° C. and the temperature of the smoking material put into the roasting container was 250° C. to 310° C.

Experimental Example 1: Evaluation of nicotine transition rate according to dry roasting process conditions

In order to evaluate the nicotine migration rate according to the dry roasting process conditions, the nicotine migration rates of the smoking articles prepared according to Examples 1 to 5 and Comparative Example 1 were analyzed and shown in Table 1. Smoking articles in Experimental Example 1 were inserted into an aerosol generating device having the same structure as the aerosol generating device 1000 shown in FIG. 7 to be described later and heated to about 150° C. to 200° C. to generate an aerosol. The nicotine transition rate was calculated as the ratio of the total amount of nicotine contained in the aerosol to the total amount of nicotine contained in smoking articles.

division roasting conditions moisture
Decrease rate (%) nicotine
Fulfillment rate (%) time (h) Internal temperature (℃) Medium temperature (℃) Comparative Example 1 Roast not in progress - 4.3 Example 1 2.5 100-150 50 to 100 2 12.5 Example 2 5 100-150 50 to 100 3 16.7 Example 3 2.5 200-250 100-180 6 24.9 Example 4 5 200-250 100-180 8 23.0 Example 5 2.5 350-400 250-310 12 13.8

As shown in Table 1, it can be confirmed that in all of Examples 1 to 5 in which dry roasted smoking material was used, a higher nicotine transfer rate was observed compared to Comparative Example 1 in which non-roasted smoking material was used. In the case of manufacturing non-combustible smoking articles by roasting, it can be expected that the nicotine transfer rate can be increased only through the roasting process without other additives, and thus the user's taste can be improved. When smoking material is used, at least part of the nicotine salt, which is an ionic bond between nicotine and organic acid, present in the smoking material before roasting is converted to a pre-nicotine state, so that when smoking a smoking article, a high taste transition is achieved even at a lower heating temperature than before. It is possible, and according to the roasting, it is possible to increase the intrinsic deep flavor of the smoking material.

In addition, the smoking material according to the embodiments of the present invention is advantageous in terms of inhalation safety of the aerosol because basic substances for increasing the amount of nicotine transfer are not added to the smoking material, and the problem of odor generation such as ammonia odor that may occur during smoking is fundamentally eliminated. In this way, it is possible to simplify the manufacturing process of smoking articles and lower the manufacturing cost as it is also unnecessary to add additional flavor to solve the odor. do.

In particular, the dry roasting method was carried out for about 2.5 hours under the condition that the temperature inside the roasting container was 200 ° C to 250 ° C and the temperature of the smoking material put into the roasting container was 100 ° C to 180 ° C, and the moisture reduction rate was about 6%. The effect of increasing the nicotine transition rate in Example 3 was found to be the most excellent. In Examples (Examples 1 and 2) of lower temperature and/or less process time compared to Example 3, the amount of conversion to the prenicotine state is not sufficient, so it is predicted that the effect of increasing the nicotine transition rate is relatively low, compared to Example 3 In the embodiments of high temperature and/or a long process time (Examples 4 to 5), moisture in the smoking material is excessively reduced by excessive heating, the smoking material is carbonized, or decomposition of prenicotine in the smoking material (Examples 4 to 5). ), the effect of increasing the nicotine transition rate is predicted to be relatively low.

On the other hand, it can also be confirmed that, in the case of the dry roasting method in Examples 1 to 5, the increase in the nicotine transfer rate was relatively large compared to the wet roasting method in Examples 8 to 12 to be described later.

Example 6

A smoking article similar to that in Example 3 was prepared except that the roasting step was performed in two stages. The roasting process of smoking material includes a first roasting stage and a second roasting stage performed after the first roasting stage, wherein the first roasting stage is performed for about 1 hour under the condition that the temperature inside the roasting container is 100°C to 150°C. and the second roasting stage was performed for about 1.5 hours under the condition that the temperature inside the roasting vessel was 200°C to 250°C.

Example 7

A smoking article similar to that in Example 3 was prepared except that the roasting step was performed in two stages. The roasting process of smoking material includes a first roasting stage and a second roasting stage performed after the first roasting stage, wherein the first roasting stage is performed for about 1 hour under the condition that the temperature inside the roasting container is 100°C to 150°C. and the second roasting stage was performed for about 1.5 hours under the condition that the temperature inside the roasting vessel was 200°C to 250°C.

Experimental Example 2

In order to evaluate the effect of increasing the nicotine migration rate according to the roasting process conditions, the nicotine migration rates of the smoking articles prepared according to Examples 3, 6 and 7 and Comparative Example 1 were analyzed and shown in Table 2.

division roasting conditions nicotine
Fulfillment rate (%) Comparative Example 1 Roast not in progress 4.3 Example 3 200~250℃, 2.5h 24.9 Example 6 Primary 100~150℃, 1h Secondary 200~250℃, 1.5h 24.1 Example 7 Primary 150~200℃, 1h Secondary 200~250℃, 1.5h 26.5

As shown in Table 2, the primary roasting is performed for 1 hour under the condition that the temperature inside the roasting container is 100° C. to 150° C., and the second roasting is performed for 1.5 hours under the condition that the temperature inside the roasting container is 200° C. to 250° C. The nicotine transfer rate in Example 6 was slightly reduced compared to Example 3, but the primary roasting was performed for 1 hour under the condition that the temperature inside the roasting container was 100° C. to 150° C., and the temperature inside the roasting container was It can be seen that the nicotine transition rate in Example 7, in which the secondary roasting was performed for 1.5 hours under the conditions of 200°C to 250°C, increased compared to Example 3.

Example 8

A smoking article similar to that of Comparative Example 1 was prepared, except that roasted smoking material was used in the smoking material part. The smoking material was roasted by a wet roasting method, and glycerol was used as the solvent. The roasting was carried out for about 3.5 hours under conditions where the temperature inside the roasting container was 100° C. to 150° C., and the temperature of the smoking material put into the roasting container was 80° C. to 140° C.

Example 9

The same smoking article as in Example 8 was prepared except that the roasting was performed for about 6 hours. That is, the roasting of the smoking material was carried out for about 6 hours under the condition that the temperature inside the roasting container was 100° C. to 150° C. and the temperature of the smoking material put into the roasting container was 80° C. to 140° C.

Example 10

Smoking articles were prepared in the same manner as in Example 8 except for the roasting temperature conditions. The roasting of the smoking material was carried out for about 3.5 hours under the condition that the temperature inside the roasting vessel was 200°C to 250°C and the temperature of the smoking material put into the roasting vessel was 180°C to 250°C.

Example 11

A smoking article similar to that in Example 10 was prepared except that the roasting was performed for about 6 hours. That is, the roasting of the smoking material was carried out for about 6 hours under the condition that the temperature inside the roasting container was 200° C. to 250° C. and the temperature of the smoking material put into the roasting container was 180° C. to 250° C.

Example 12

Smoking articles were prepared in the same manner as in Example 8 except for the roasting temperature conditions. The roasting of the smoking material was carried out for about 3.5 hours under the condition that the temperature inside the roasting container was 350° C. to 400° C. and the temperature of the smoking material put into the roasting container was 300° C. to 360° C.

Experimental Example 3: Evaluation of nicotine transition rate according to wet roasting process conditions

In order to evaluate the nicotine migration rate according to the wet roasting process conditions, Table 3 shows the nicotine migration rates of smoking articles prepared according to Examples 8 to 12 and Comparative Example 1 described above.

division roasting conditions moisture
Decrease rate (%) nicotine
Fulfillment rate (%) time (h) Internal temperature (℃) Medium temperature (℃) Comparative Example 1 Roast not in progress - 4.3 Example 8 3.5 100-150 80-140 One 15.6 Example 9 6 100-150 80-140 2 18.2 Example 10 3.5 200-250 180-250 4 22.4 Example 11 6 200-250 180-250 5 20.0 Example 12 3.5 350-400 300-360 7 18.9

As shown in Table 3, it can be confirmed that in all of Examples 8 to 12 in which wet roasted smoking materials were used, higher nicotine transfer rates were observed compared to Comparative Example 1 in which non-roasted smoking materials were used. In particular, the inside of the roasting container In Example 10, the moisture reduction rate was about 4%, which was carried out by a wet roasting method for about 3.5 hours under the condition that the temperature of 200 ° C. to 250 ° C. and the temperature of the smoking material put into the roasting container was 180 ° C to 250 ° C. It was found that the effect of increasing the nicotine transfer rate was the most excellent among wet roasting Examples 8 to 12.

On the other hand, comparing the nicotine transfer rate of Example 8 and Example 1 (see Table 1), when the temperature inside the roasting container is 100 ° C to 150 ° C, wet roasting (Example 8) is dry roasting (Example 1) It was found to be more advantageous in increasing the nicotine adherence rate compared to the previous study. In addition, comparing the nicotine transfer rates of Example 12 and Example 5 (see Table 1), when the temperature inside the roasting container was 350 ° C to 400 ° C, also wet roasting (Example 12) was compared to dry roasting (Example 5) ) compared to the nicotine transition rate. However, comparing the nicotine migration rates of Example 10 and Example 3 (see Table 1), dry roasting (Example 3) was found to be more advantageous in securing the maximum nicotine migration rate compared to wet roasting (Example 10).

Based on these results, it can be seen that dry roasting is more advantageous to maximize the increase in nicotine transfer rate, but dry roasting has more influence on roasting conditions than wet roasting.

Experimental Example 4: Sensory evaluation

Sensory evaluation during smoking was performed on smoking articles of Comparative Example 1 in which non-roasted smoking material was employed, Examples 3 and 5 in which dry roasting smoking material was employed, and Example 10 in which wet roasting was performed. Sensory characteristics evaluation was conducted for a total of 61 evaluation panel members, and a total of 7 points was used as the standard.

2 is an evaluation result of sensory properties of smoking articles according to Comparative Examples 1, 3, 5, and 10; As shown in FIG. 2 , in all of Examples 3, 5 and 10, the feeling of hitting and taste during smoking was greater than that of Comparative Example 1.

In Examples 3 and 10, it can be seen that the off-flavor was lowered compared to Comparative Example 1, but in Example 5 it could be confirmed that the off-taste was rather increased compared to Comparative Example 1, which was caused by the roasting temperature higher than necessary in Example 5. It is expected that the taste and taste increase due to carbonization of the smoking material.

In Examples 3 and 10, it was confirmed that the feeling of hitting and taste during smoking increased and at the same time, the effect of reducing the taste and taste was also present, and this effect was confirmed to be more pronounced in Example 3.

Meanwhile, the roasted smoking material according to the embodiments of the present invention described above is employed in the smoking material units 110, 210, and 310 of the non-combustible smoking articles 100, 200, and 300 shown in FIGS. 3 to 5 . can be However, of course, the structure of the non-combustible smoking article employing the roasted smoking material part is not limited thereto.
