Embodiment of the invention

Hereinafter, the present invention will be described in detail. In the present invention, "X to Y" includes X and Y which are fractional values thereof.
The production method of the present invention includes a step 1 of humidifying and then drying the tobacco filling, and a step 2 of preparing a tobacco rod portion in which the tobacco filling obtained in the step 1 is filled in a tubular wrapper.
1. 1. Process 1
(1) Tobacco filling The tobacco filling is a material that is filled in a wrapper and used for smoking. Although known tobacco fillers can be used in the present invention, it is preferable to include a tobacco sheet from the viewpoint of ease of production. The tobacco sheet is a sheet-shaped tobacco material, and in the present invention, a reconstructed tobacco sheet is preferable. In one aspect, the term "tobacco sheet" means a sheet-like tobacco material or a material derived from the sheet-like tobacco material (eg, a cut piece). The reconstituted tobacco sheet is a tobacco sheet containing a reconstituted product (reconstructed tobacco or reconstituted tobacco granules) composed of fine powder of a plant belonging to the genus Tobacco. The tobacco sheet may be a papermaking sheet manufactured by a papermaking method, a cast sheet manufactured by a casting method, or an extrusion sheet manufactured by an extrusion method.

The papermaking method is a method in which a mixture containing a tobacco raw material and a liquid medium such as water is made into paper and dried to produce a sheet. The mixture usually contains pulp or fibrous tobacco material. The casting method is a method in which a mixture containing a tobacco raw material and a liquid medium such as water is developed (cast) on a substrate and dried to produce a sheet. The extrusion method is a method for producing a sheet by extruding a mixture containing a tobacco raw material and a liquid medium such as water from a die such as a T die.

The tobacco filling may contain an aerosol-forming substrate. The aerosol-forming substrate is a material that is vaporized and cooled by heating to form an aerosol, or is atomized to produce an aerosol. Known aerosol-forming substrates can be used, and examples thereof include polyhydric alcohols such as glycerin and propylene glycol (PG), triethylcitrate (TEC), triacetin and the like having a boiling point of more than 100 ° C. Can be mentioned. The amount of the aerosol-forming substrate in the tobacco filling is preferably 1 to 40% by weight, more preferably 5 to 30% by weight, still more preferably, by dry weight (weight excluding mixed water, the same applies hereinafter). It is 5 to 20% by weight. If the amount of the aerosol-forming substrate exceeds the upper limit, it may be difficult to manufacture the tobacco filling, and if it is less than the lower limit, the amount of smoke sensation may decrease.

When using a reconstructed tobacco sheet, it is preferable to release the sheet-fed form and supply it quantitatively to step 1. Release means to loosen the reconstructed tobacco sheet (in the form of a single leaf) that is laminated and agglomerated into one sheet. The size is not limited, but in one embodiment, the single-leaf reconstructed tobacco sheet is a columnar body, and its cross section is a quadrangle having a side of 3 to 10 cm.

When transporting a single-leaf regenerated tobacco sheet, it is preferable to fill it in a packaging container having a shape and size that is easy to handle. An example of a packaging container is the C-48 box, which is known among cigarette manufacturers. The C-48 box is made of cardboard and measures approximately 115 x 70 x 75 cm. The single-wafer regenerated tobacco sheet can be directly filled in the C-48 box, but may be packed in a plastic bag and then housed in the C-48 box in order to suppress quality changes during transportation. .. According to the embodiment of the present application, the C-48 box is filled with about 100 to 200 kg of a reconstructed tobacco sheet in a single-wafer form.

Another aspect is a method of transporting a recycled tobacco sheet in a bobbin shape. In the reconstructed sheet manufacturing process, a vertically continuous sheet having a width of 10 to 100 cm can be wound around a core to form a bobbin shape. When the regenerated tobacco sheet transported in the bobbin shape is used in the present invention, it is necessary to cut the reconstructed tobacco sheet to a predetermined size using a shredder or the like before the reconstructed tobacco sheet is subjected to the step 1.

(2) Humidification Humidification can be performed using a known device, but in the present invention, it is preferable to use a cylinder type device from the viewpoint of efficiency. The device includes a water supply device, a heating device, an exhaust device, and a rotating device that rotates around the central axis of the cylinder. Humidification is carried out by supplying water from the water supply device to the tobacco filling. The humidification conditions are adjusted so that the water content of the tobacco filling after humidification is about 15 to 25% by weight. In one embodiment, the temperature of the inner wall of the cylinder can be set to 50 to 70 ° C., the flow rate of air in the cylinder can be set to 0.05 to 0.15 m / sec, and the residence time of the tobacco filling can be set to about 3 to 6 minutes. The size of the cylinder is not limited, but in one embodiment, the diameter is about 2 to 4 m and the length is about 5 to 10 m. Humidification is more preferably carried out by ventilating the inside of the cylinder. When the tobacco filling is heated, some of the low boiling point content components such as ammonia are volatilized and discharged to the outside of the cylinder by exhaust gas, thereby reducing the negative taste and aroma during use.

(3) Drying By drying, the tobacco filling can be put into a state suitable for storage. Drying can be performed by a known method, but in the present invention, it is preferable to adopt an air flow drying method or an annual drying method from the viewpoint of efficiency. The former is a method in which a heated air flow (preferably superheated steam) and a tobacco filling are brought into contact with each other in a pipe to perform drying. Examples of such a device include those described in International Publication 2013/052490. In this method, it is also possible to give a characteristic flavor character to the tobacco filling. In this method, the moisture in the tobacco filling is dried in a short time, so that the dried tobacco filling can be inflated compared to before drying, and the shape of the dried tobacco filling is curled. Therefore, the bulkiness of the tobacco filling increases. In addition, since it is dried in a short time under the atmosphere of a large amount of superheated steam, the amount of oxygen in the atmosphere when heated in the drying step can be reduced, and the chemical change of the unwanted tobacco filling caused by oxygen is suppressed. can.

The latter is a method of heating and drying the tobacco filling in a cylinder type device. With this method, it is also possible to remove highly volatile components contained in the tobacco filling. Since this method requires a longer time to dry than the air flow drying method, it is preferable in that fine moisture control can be performed and accurate finish of outlet moisture can be achieved.

(4) Embodiment Hereinafter, step 1 will be described with reference to preferred embodiments.
(4-1) First Embodiment 1) Preparation Figure 1 shows the first embodiment. According to this embodiment, a reconstructed tobacco sheet in a single-wafer form is prepared and released. The water content of the reconstituted tobacco sheet at this stage is preferably 5 to 15% by weight. The aerosol-forming substrate is added before or after release. The amount of the aerosol-forming substrate in the sheet is preferably 5 to 30% by weight. Foreign matter is removed from the released reconstituted tobacco sheet. It is also possible to use a blend silo to mix the reconstituted tobacco sheets to homogenize the quality.

2) Humidification Next, humidify the reconstituted tobacco sheet. The equipment used for humidification and the humidification conditions are as described above. At this time, the water content of the reconstituted tobacco sheet is adjusted to 15 to 25% by weight. Further, in this step, unfavorable components derived from the tobacco raw material (components that give an astringent taste, etc.) are removed.

3) Addition of additives (incense)
In this step, additives are added to the reconstituted tobacco sheet after humidification. The additive is a material other than a raw material such as a reconstructed tobacco sheet and an aerosol-forming base material. Additives include tobacco powder; fragrances; the aforementioned aerosol-producing substrates; tobacco aroma enhancers such as acids and alkalis; solvents such as ethanol, water, benzyl alcohol and propylene glycol; antioxidants such as polyphenols or vitamins. Be done. The additive can be added by a known method, but it can be carried out by filling a rotating cylinder type device with a reconstructed tobacco sheet and spraying a fragrance or the like. Above all, the addition of tobacco powder or fragrance, which is a flavor component, is particularly referred to as fragrance, and in this embodiment, it is preferable to perform fragrance. The aroma at this stage is suitable for adding a flavor component having a relatively large molecular weight. This is because such a flavor component has a low vapor pressure and a high affinity with water, and therefore, when added to a reconstituted tobacco sheet after humidification, it easily penetrates into the inside of the sheet.

The fragrances include the following, which can be used alone or in combination of two or more.
Acetanisol, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, trans-annetol, staranis oil, apple juice, peruval balsam oil, honeywort absolute, benzaldehyde, benzoin resinoid, benzyl alcohol, benzoate Lactone benzyl acid, benzyl phenylacetate, benzyl propionate, 2,3-butandione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamon oil, carobu absolute, β-carotene, carrot juice, L-carboxylic, β-cariophyllene, cassia Bark oil, cedar wood oil, celery seed oil, chamomile oil, cinnamaldehyde, silicic acid, cinnamyl alcohol, cinnamyl silicate oil, citronella oil, DL-citronellol, clarisage extract, cocoa, coffee, cognac oil, coriander oil, Cuminaldehyde, davana oil, δ-decalactone, γ-decalactone, decanoic acid, dill herb oil, 3,4-dimethyl-1,2-cyclopentandione, 4,5-dimethyl-3-hydroxy-2,5-dihydro Fran-2-one, 3,7-dimethyl-6-octenoic acid, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, ethyl 2-methylbutyrate, ethyl acetate, ethyl butyrate, Ethyl hexaneate, ethyl isovalerate, ethyl lactate, ethyl laurate, ethyl levulinate, ethyl maltor, ethyl octanate, ethyl oleate, ethyl palmitate, ethyl phenylacetate, ethyl propionate, ethyl stearate, ethyl valerate , Ethylvaniline, ethylvaniline glucoside, 2-ethyl-3, (5 or 6) -dimethylpyrazine, 5-ethyl-3-hydroxy-4-methyl-2 (5H) -furanone, 2-ethyl-3-methylpyrazine , Eucalyptor, Pheneglique Absolute, Gene Absolute, Lindow Root Infusion, Geraniol, Geranyl Acetate, Grape Juice, Guayacol, Guava Extract, γ-Heptalactone, γ-Hexalactone, Hexanoic Acid, Sis-3-Hexen-1 -Ol, hexyl acetate, hexyl alcohol, phenylacetate hexyl, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4- (3-hydroxy-1-butenyl) -3,5,5-trimethyl-2 -Cyclo Hexen-1-one, 4- (para-hydroxyphenyl) -2-butanone, sodium 4-hydroxyundecanoate, immortel absolute, β-ionone, isoamyl acetate, isoamyl butyrate, isoamyl phenylacetate, isobutyl acetate, phenylacetic acid Isobutyl, jasmine absolute, cola nut tincture, labdanum oil, lemon terpenless oil, kanzo extract, linalol, linaryl acetate, lobage root oil, maltol, maple syrup, menthol, menthon, L-mentyl acetate, paramethoxybenzaldehyde, methyl -2-Pyrrolyl ketone, Methyl anthranilate, Methyl phenylacetate, Methyl salicylate, 4'-Methylacetophenone, Methylcyclopentenolone, 3-Methylvaleric acid, Mimosa absolute, Toumitsu, Myristic acid, Nerol, Nerolidel, γ-Nonalactone, Natsumegu oil, δ-octalactone, octanal, octanoic acid, orange flower oil, orange oil, orris root oil, palmitic acid, ω-pentadecalactone, peppermint oil, petitgrain paraguay oil, phenethyl alcohol, phenylacetate phenethyl, phenylacetic acid , Piperonal, Plum Extract, Propenylguaetol, propyl Acetate, 3-Propyridenphthalide, Prune Juice, Pyruvate, Rasen Extract, Rose Oil, Lamb Liquor, Sage Oil, Sandalwood Oil, Sparemint Oil, Stilax Absolute, marigold oil, tea distillate, α-terpineol, terpinyl acetate, 5,6,7,8-tetrahydroquinoxaline, 1,5,5,9-tetramethyl-13-oxacyclo (8.3.0.0) (4.9)) Tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil, tomato extract, 2-toridecanone, triethyl citrate, 4- (2,6,6-trimethyl-1-cyclohexenyl) ) 2-Buten-4-one, 2,6,6-trimethyl-2-cyclohexene-1,4-dione, 4- (2,6,6-trimethyl-1,3-cyclohexadienyl) 2-buten- 4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin, veratoraldehyde, violet leaf absolute, N-ethyl-p-menthan-3-carbamide ( WS-3), ethyl-2- (p-mentor) N-3-Carboxamide) Acetate (WS-5), sugar (sucrose, fructose, etc.), cocoa powder, carob powder, coriander powder, licorice powder, orange peel powder, rose pip powder, chamomile flower powder, lemon verbena Powder, peppermint powder, leaf powder, sparemint powder, black tea powder, natural vegetable fragrances (eg jasmine oil, lemon oil, vetiver oil, lobage oil), esters (eg mentyl acetate, isoamyl propionate, etc.), alcohol Kinds (eg, phenylethyl alcohol, cis-6-nonen-1-ol, etc.).

It is also preferable to add an antioxidant as an additive. It has been reported that TSNAs (Tobacco specific nitrosamines) are contained in the tobacco vapor of the non-combustion heating type flavor suction article (Non-Patent Document 1). In the non-combustion heating type flavor suction article, the tobacco filling is continuously heated for a long time at the time of use. Therefore, in the tobacco filling of the non-combustion heating type flavor suction article, unintended components may be generated by heating for a long time. By adding an antioxidant, the above reaction can be suppressed and the production of unintended components can be suppressed.

As the antioxidant, for example, an antioxidant known as a food additive can be used. Examples include ascorbic acid, erythorbic acid, ascorbic acid, catechin, dihydrocaffeic acid, p-coumaric acid, ferulic acid, 3- (4-hydroxyphenyl) propionic acid, quercetin, esculetin, kenferol, caffeic acid, tocopherol, Examples include dibutylhydroxytoluene (BHT), quinic acid, chlorogenic acid, rutin, scopoletin, and cinnamic acid. The antioxidant is preferably at least one selected from the group consisting of gallic acid and erythorbic acid. The antioxidant is contained in the tobacco filling in an amount of, for example, 0.25 to 10% by weight, preferably 0.25 to 5.0% by weight, more preferably% by weight, based on the tobacco filling. The antioxidant can be added to the tobacco filling by melting or dispersing it in a solvent such as water or ethanol and spraying it.

4) Stamping In this process, the scented reconstituted tobacco sheet is stamped. The cutting can be performed using a known device, but in the present invention, the reconstructed tobacco sheet is supplied by pressing and supplying the reconstructed tobacco sheet so that its end is parallel to the extending direction of the blade of the knife drum, and the strand is It is preferable to cut it into a shape. The shape of the strand can be about 0.6 to 1.5 mm in width from the viewpoint of ease of filling the wrapper. The length of the strand after cutting is the size of the sheet-fed reconstructed tobacco sheet supplied to the cutting process, and the crushed state of the sheet-fed reconstructed tobacco sheet in each process, during cutting, and cutting. Although it is determined by the crushed state of the subsequent strand, it is preferably about 5 to 40 mm from the viewpoint of ease of filling in the wrapper. It is preferable to supply the reconstructed tobacco sheet to the cutting machine using a metering tube. In this step, in order to efficiently perform cutting, the water content of the reconstructed tobacco sheet supplied to the cutting step may be adjusted to 15 to 25% by weight.

5) Drying In this step, the strand-shaped reconstructed tobacco sheet is dried. The equipment and drying conditions used for drying are as described above. At this time, the water content of the reconstituted tobacco sheet is adjusted to 8 to 12% by weight. Further, in this step, the bulkiness of the strand-shaped reconstructed tobacco sheet is improved.

6) Mixing of non-tobacco materials In this step, a solid additive carrying a filler or a fragrance is added to the strand-shaped reconstructed tobacco sheet. Examples of the filler include strand-shaped paper, strand-shaped calcium carbonate sheet, granular porous polysaccharide beads, and the like. From the viewpoint of enhancing the mixing property, it is preferable that the material to be added has a shape close to that of the strand. For example, adding a perfume-carrying polysaccharide sheet as a solid additive carrying a perfume has an advantage that the taste and aroma at the time of use of a non-combustion heating type flavor suction article can be enhanced. The perfume-supporting sheet to be mixed with the tobacco filler is based on the thickening polysaccharide disclosed in Japanese Patents 5941988, 5934799, 5514953, and 541574. It is preferable in terms of the balance of fragrance release performance during use. The shape of the fragrance-supporting polysaccharide sheet can be 0.5 to 1.5 mm in width, 2 to 4 mm in length, and about 70 μm in thickness. The mixing method is not limited, and a method of merging a conveyor carrying a strand-shaped reconstructed tobacco sheet with a conveyor carrying an engraved fragrance-supporting polysaccharide sheet and mixing the two, or both. Is introduced into a cylinder type mixer and mixed.

7) Incense Incense may be applied again to the reconstructed tobacco sheet having a strand shape after drying. The method of incense and the components used are as described above. The aroma at this stage is suitable for adding a flavor component having a relatively small molecular weight. After this step, the tobacco filling can be processed into a flavor-sucking article without drying. Therefore, in this step, a strong scent characteristic should be given to the final product by adding a flavor component that expresses a relatively volatile scent. Can be done.

8) Primary storage The strands thus obtained are stored. The stored tobacco filler (strand) is subjected to step 2.

(4-2) Second Embodiment FIG. 2 shows a second embodiment. In this embodiment, two lines are used. In one line, the reconstructed tobacco sheet A is prepared by carrying out 1) to 3) of the first embodiment. Similarly, in the other line, 1) to 3) of the first embodiment are carried out to prepare the reconstructed tobacco sheet B. At this time, it is preferable that the reconstituted tobacco sheets A and B are composed of different components. Further, the incense may be applied to both the reconstituted tobacco sheets A and B, may be applied to one of them, or may not be applied to both of them.

Next, the reconstituted tobacco sheets A and B are mixed. The mixing ratio is appropriately adjusted so that the desired flavor can be achieved. By mixing the two at this point, the mixing efficiency can be improved, and the mixed product can be subjected to processes such as cutting and drying, so that the product can be made more uniform.

Subsequently, the mixture of the reconstituted tobacco sheets A and B is subjected to a cutting, drying, mixing with a non-tobacco material, and aromatling process, and the obtained product is first stored. These steps are as described in the first embodiments 4) to 8).

This aspect is suitable for manufacturing brands with different flavor characteristics. For example, when the base material common to these brands is the reconstructed tobacco sheet A, another brand can be efficiently manufactured by appropriately using the reconstructed tobacco sheet B which is a sub-raw material at the time of brand switching. In addition, if there is a missing component in the analysis of the reconstituted tobacco sheet A during the production of the reconstructed tobacco sheet A, the quality is stabilized by mixing the reconstructed tobacco sheet B designed to supplement the component. Mixtures of reconstituted tobacco sheets can also be produced.

Examples of the types of tobacco used as the material for reconstituted tobacco include yellow species, Burley species, Orient species, and native species in Nicotiana rustica, which can be used alone or in combination. Usually, these blend ratios are changed to achieve the desired taste and aroma. As a design concept for blending sheet A and sheet B, for example, the ratio of yellow type and orient type is increased as the constituent tobacco types (the total amount of both is preferably more than 50% by weight of the total amount of tobacco). Sheet A was prepared (more preferably 80% by weight or more), and the proportion of Burley or native species was increased as the constituent tobacco types (the total amount of both is preferably more than 30% by weight of the total amount of tobacco). , More preferably 80% by weight or more) Prepare the sheet B. By determining the blending ratio of the sheet A and the sheet B according to the desired taste and aroma, it is possible to produce a flavor suction article having a large number of variations while preparing two types of sheets.

In addition to the above-mentioned four types of tobacco whose flavor changes depending on the type, there are types of tobacco having strong taste and aroma characteristics even in a small amount. Examples of such cigarettes include cigarettes called Peric, Latakia, and Dark Fire Cured. These varieties are the same as the yellow, Burley, Orient, or Native varieties described above, but are smoked or fermented under forced high temperature and high moisture after harvesting at leaf tobacco farmers. Specially treated tobacco, such as fermented tobacco such as pellic and dark fire cure, or smoked tobacco such as latakia, is slightly blended to give it a unique flavor characteristic. Express. When a reconstructed tobacco sheet containing pellic, latakia, dark fire cure, etc. is used as the sheet B, the variation of brand characteristics can be expanded. The total blending amount of peric, latakia and dark fire cure is preferably 1.0% by weight or more and less than 10.0% by weight, more preferably 1.0% by weight or more and less than 5.0% by weight of the total amount of tobacco. Is.

(4-3) Third Embodiment FIG. 3 shows a third embodiment. In this embodiment, two lines are used. In one line, 1) to 5) of the first embodiment are carried out to prepare a strand-shaped reconstructed tobacco sheet A. Similarly, in the other line, 1) to 5) of the first embodiment are carried out to prepare a strand-shaped reconstituted tobacco sheet B. At this time, it is preferable that the reconstituted tobacco sheets A and B are composed of different components. Further, the incense may be applied to both the reconstituted tobacco sheets A and B, or may be applied to one of them.

Next, the strand-shaped reconstituted tobacco sheets A and B are mixed. The mixing ratio is appropriately adjusted so that the desired flavor can be achieved.

Subsequently, the mixture is subjected to a mixing and incense step with a non-tobacco material, and the obtained product is first stored. These steps are as described in the first embodiments 6) and 7).

This aspect is suitable for producing a brand having different flavor characteristics as in the second aspect. For example, when the base material common to these brands is the reconstructed tobacco sheet A, another brand can be efficiently manufactured by appropriately using the reconstructed tobacco sheet B which is a sub-raw material at the time of brand switching. In addition, if there is a missing component in the analysis of the reconstituted tobacco sheet A during the production of the reconstructed tobacco sheet A, the quality is stabilized by mixing the reconstructed tobacco sheet B designed to supplement the component. The reconstituted tobacco sheet A can also be manufactured. Further, in this embodiment, the reconstructed tobacco sheets A and B are subjected to cutting and drying, respectively, so that the conditions can be set according to the individual characteristics. For example, when the fragrance added to the reconstituted tobacco sheet A and the fragrance added to the reconstructed tobacco sheet B are different, the optimum drying conditions differ depending on the fragrance, but in this embodiment, there is an advantage that conditions suitable for the fragrance can be selected. There is.

(4-4) Fourth Embodiment FIG. 4 shows a fourth embodiment. In this embodiment, two lines are used. In one line, the reconstructed tobacco sheet A is processed by carrying out 1) to 3) of the first embodiment. Similarly, in the other line, lamina is processed. Lamina is a deboned leaf obtained by removing the middle bone from tobacco leaves. FIG. 4 shows a form in which two types of laminas are used, but one or more types of laminas can be used. At this time, it is preferable that Lamina A and B are composed of different components. The steps up to the scenting step of lamina can be carried out in the same manner as in 1) to 3) of the first embodiment.

Next, Lamina A and B are mixed, and the mixture is further humidified. Humidification can be carried out in the same manner as in 2) of the first embodiment. The humidified mixture is further mixed with the aromatized reconstituted tobacco sheet A, which is then subjected to a cutting, drying, mixing with non-tobacco material and aromatizing steps, and the obtained product is first stored. .. These steps are as described in the first embodiments 4) to 8). Further, the incense may be applied to one or more of the reconstituted tobacco sheets A, Lamina A, and Lamina B, or may be applied to all of them.

In this aspect, the effect described in the second aspect can be obtained. Further, if a lamina having a higher swelling property than that of the tobacco sheet is mixed, the filling amount for achieving the same winding hardness can be reduced as compared with the case where the tobacco rod portion is formed only by the tobacco sheet.

(4-5) Fifth Embodiment FIG. 5 shows a fifth embodiment. In this embodiment, two lines are used. In one line, 1) to 5) of the first embodiment are carried out to prepare a strand-shaped reconstructed tobacco sheet A. Similarly, in the other line, a mixture of lamina A and B is prepared in the same manner as in 1) to 3) of the first embodiment, and this is further applied to 2), 3), 5 of the first embodiment. ), Humidify, cut and dry.

Next, the strand-shaped reconstituted tobacco sheet A and the strand-shaped lamina mixture are mixed. The mixing ratio is appropriately adjusted so that the desired flavor can be achieved.

Subsequently, the mixture is subjected to a mixing and incense step with a non-tobacco material, and the obtained product is first stored. These steps are as described in the first embodiments 6) and 7). Further, the incense may be applied to one or more of the reconstituted tobacco sheets A, Lamina A, and Lamina B, or may be applied to all of them.

In this aspect, the effect described in the third aspect can be obtained. Further, as described in the fourth aspect, the filling amount can be reduced.

(5) Other Steps The production method of the present invention may further include a step of measuring the components of the tobacco filling and adjusting the addition amount of the additive based on the measurement result. At this time, it is preferable to convey the measurement result to the controller so that the information can be transmitted from the controller to the additive addition device. In particular, it is preferable to measure the nitrite of the tobacco filling and determine the amount of the antioxidant added based on this. If the amount of the antioxidant added is excessive, the cost will increase or the flavor will be impaired. Therefore, by determining the appropriate amount, it is possible to provide a user-friendly product without causing such a problem.

(6) Preparation of Reconstructed Tobacco Sheet The following describes a preferred embodiment for preparing the reconstructed tobacco sheet.
(6-1) Papermaking method As the tobacco plant material, yellow species, Burley species, Orient species, or native species in Nicotiana tabacum can be used alone or in combination. The plant site may be any one or combination of flowers, leaves, veins, stems, or roots.

Tobacco plant material is roughly crushed to a size of about 1 to 40 mm or less and used for extraction with water. The extraction temperature is preferably 30 to 90 ° C., and the extraction time is preferably 10 to 45 minutes.

Next, the mixture that has undergone the extraction step is subjected to a separation operation by centrifugation or using a wire mesh, and is separated into an extract and a residue. The extract is concentrated under reduced pressure under a temperature condition of 40 to 70 ° C. so that the ratio of the extract to water is 40 to 55% by weight. An aerosol-forming substrate such as glycerin is mixed with the concentrated solution. After mixing the residue with the coarsely ground wood pulp, it is treated with a refiner to make the fibers fluffy, and then further ground to make the size uniform. A mixture of the residue and wood pulp is suspended in a large amount of water, supplied in a fixed amount on a mesh wire used in a paper manufacturing process, dehydrated and dried to obtain a sheet. The concentrate is sprayed onto the sheet. After spraying, dry again. Finally, the sheet may be bobbin-wound, or may be shredded, cut into 3 to 10 cm squares, and stored in a container.

2. 2. Step 2
In this step, a tobacco rod portion in which the tobacco filler obtained in step 1 is filled in a tubular wrapper is prepared. For example, a tobacco rod portion can be manufactured by preparing paper as a wrapper and wrapping the tobacco filler with the paper. Alternatively, the tobacco rod portion can be manufactured by preparing a tubular wrapper and filling the inside thereof with a tobacco filler. The cross-sectional shape of the tubular wrapper is not limited and can be circular, elliptical, or polygonal.

3. 3. Characteristics The tobacco filling obtained by the production method of the present invention has particularly excellent swelling property. The swelling property is a volume per unit weight when a mass of tobacco filling (preferably chopped) is compressed with a constant force, and is also an index of bulk density. Specifically, it is calculated by the following formula from the height of the tobacco carved cylinder obtained after applying a load of 11.4 kg in a measuring cylinder having a diameter of 95 mm in which the sample is placed for 5 seconds.
FP = (A × h5) / W [cm ³ / 100g]
FP: Bulkiness A: Cross-sectional area of the tobacco carved cylinder W: Weight of the tobacco carved h5: Height of the tobacco carved cylinder at the end of the load

The tobacco rod part of the flavor suction article (or smoking article) is mainly manufactured by wrapping the tobacco filling with a columnar paper wrapper. Generally, the tobacco rod part tends to be preferred by users if it is hard to some extent. To make the tobacco rod part harder, it is conceivable to increase the filling amount of the tobacco filling, but increasing the filling amount causes an increase in cost. However, a highly bulging tobacco filler can provide a tobacco rod portion with the required hardness with a smaller filling amount.

3. 3. Non-combustion heating type flavor suction article Smoking articles include flavor suction articles in which the user tastes the flavor by suction, and smokeless tobacco (smokeless smoking article) in which the user tastes the flavor by directly including the product in the nasal cavity and oral cavity. The flavor suction article can be roughly classified into a combustion type smoking article typified by a conventional cigarette and a non-combustion type smoking article. The tobacco rod portion of the present invention is used for non-combustion heating type flavor suction articles used by heating among non-combustion type smoking articles.

The non-combustion heating type flavor suction article may be heated by a heating device separate from the article, or may be heated by a heating device integrated with the article. In the former flavor suction article (separate type), the non-combustion heating type flavor suction article and the heating device are collectively referred to as a "non-combustion heating type smoking system". An example of a non-combustion heating type smoking system will be described below with reference to FIGS. 6 and 7.

FIG. 6 is a schematic cross-sectional view showing an example of a non-combustion heating type smoking system, and shows a state before inserting the heater 12 into the tobacco rod portion 20A of the non-combustion heating type flavor suction article 20. At the time of use, the heater 12 is inserted into the tobacco rod portion 20A. FIG. 7 is a cross-sectional view of the non-combustion heating type flavor suction article 20.

As shown in FIG. 6, the non-combustion heating type smoking system includes a non-combustion heating type flavor suction article 20 and a heating device 10 for heating the tobacco rod portion 20A from the inside. However, the non-combustion heating type smoking system is not limited to the configuration shown in FIG.

The heating device 10 shown in FIG. 6 includes a body 11 and a heater 12. Although not shown, the body 11 may include a battery unit and a control unit. The heater 12 can be a heater due to electric resistance, and is inserted into the tobacco rod portion 20A to heat the tobacco rod portion 20A.

The figure shows a mode in which the tobacco rod portion 20A is heated from the inside. However, the aspect of the non-combustion heating type flavor suction article 20 is not limited to this, and in another aspect, the tobacco rod portion 20A is heated from the outside.

The heating temperature by the heating device 10 is not particularly limited, but is preferably 400 ° C. or lower, more preferably 50 to 400 ° C., and even more preferably 150 to 350 ° C. The heating temperature refers to the temperature of the heater 12 of the heating device 10.

As shown in FIG. 7, the non-combustion heating type flavor suction article 20 (hereinafter, simply referred to as “flavor suction article 20”) has a cylindrical shape. The circumference of the flavor suction article 20 is preferably 16 mm to 27 mm, more preferably 20 mm to 26 mm, and even more preferably 21 mm to 25 mm. The total length (horizontal length) of the flavor suction article 20 is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and even more preferably 50 mm to 60 mm.

The flavor suction article 20 is composed of a tobacco rod portion 20A, a filter portion 20C constituting a mouthpiece, and a connecting portion 20B connecting these.

The tobacco rod portion 20A has a columnar shape, and its total length (length in the axial direction) is preferably, for example, 5 to 100 mm, more preferably 10 to 50 mm, and more preferably 10 to 25 mm. More preferred. The shape of the cross section of the tobacco rod portion 20A is not particularly limited, but may be, for example, a circular shape, an elliptical shape, a polygonal shape, or the like.

The tobacco rod portion 20A has a tobacco filling 21 and a wrapper 22 wrapped around the tobacco filling 21. Further, the wrapper 22 may be a tobacco sheet made of the tobacco filler of the present invention.

The filter unit 20C has a cylindrical shape. The filter unit 20C has a rod-shaped first segment 25 filled with cellulose acetate acetate fiber and a rod-shaped second segment 26 also filled with cellulose acetate acetate fiber. The first segment 25 is located on the tobacco rod portion 20A side. The first segment 25 may have a hollow portion. The second segment 26 is located on the mouthpiece side. The second segment 26 is solid. The first segment 25 is composed of a first packed layer (cellulose acetate acetate fiber) 25a and an inner plug wrapper 25b wound around the first packed layer 25a. The second segment 26 is composed of a second packed layer (cellulose acetate acetate fiber) 26a and an inner plug wrapper 26b wound around the second packed layer 26a. The first segment 25 and the second segment 26 are connected by an outer plug wrapper 27. The outer plug wrapper 27 is adhered to the first segment 25 and the second segment 26 with a vinyl acetate emulsion-based adhesive or the like.

The length of the filter portion 20C is, for example, 10 to 30 mm, the length of the connecting portion 20B is, for example, 10 to 30 mm, the length of the first segment 25 is, for example, 5 to 15 mm, and the length of the second segment 26 is, for example, 5 to 15 mm. can do. The length of each of these individual segments is an example, and can be appropriately changed depending on the manufacturing aptitude, the required quality, the length of the tobacco rod portion 20A, and the like.

For example, the first segment 25 (center hole segment) is composed of a first packed layer 25a having one or more hollow portions and an inner plug wrapper 25b covering the first packed layer 25a. The first segment 25 has a function of increasing the strength of the second segment 26. The first packed layer 25a of the first segment 25 is filled with, for example, cellulose acetate fibers at a high density. A plasticizer containing triacetin is added to the cellulose acetate fiber in an amount of, for example, 6 to 20% by weight based on the weight of the cellulose acetate and cured. The hollow portion of the first segment 25 has, for example, an inner diameter of φ1.0 to φ5.0 mm.

The first packed layer 25a of the first segment 25 may be composed of, for example, a relatively high fiber filling density, or may be equivalent to the fiber filling density of the second packed layer 26a of the second segment 26 described later. May be good. Therefore, at the time of suction, air or aerosol flows only in the hollow portion, and almost no air or aerosol flows in the first packed bed 25a. For example, in the second segment 26, when it is desired to reduce the decrease due to the filtration of the aerosol component, for example, the length of the second segment 26 can be shortened and the first segment 25 can be lengthened by that amount.

Replacing the shortened second segment 26 with the first segment 25 is effective for increasing the delivery amount of the aerosol component. Since the first packed layer 25a of the first segment 25 is a fiber packed layer, the feeling of touch from the outside during use does not cause a sense of discomfort to the user.

The second segment 26 is composed of a second packed layer 26a and an inner plug wrapper 26b that covers the second packed layer 26a. The second segment 26 (filter segment) is filled with cellulose acetate fibers at a general density and has the filtering performance of a general aerosol component.

The filtration performance for filtering the aerosol (mainstream smoke) emitted from the tobacco rod portion 20A may be different between the first segment 25 and the second segment 26. At least one of the first segment 25 and the second segment 26 may contain a fragrance. The structure of the filter unit 20C is arbitrary, and may be a structure having a plurality of segments as described above, or may be composed of a single segment. Further, the filter unit 20C may be composed of one segment. In this case, the filter unit 20C may be composed of either the first segment or the second segment.

The connecting portion 20B has a cylindrical shape. The connecting portion 20B has a paper tube 23 formed in a cylindrical shape by, for example, thick paper. The connecting portion 20B may be filled with a cooling member for cooling the aerosol. Examples of the cooling member include a sheet of a polymer such as polylactic acid, and the sheet can be folded and filled. Further, a support portion for suppressing the position of the tobacco rod portion 20A from fluctuating may be provided between the tobacco rod portion 20A and the connecting portion 20B. The support portion can be made of a known material such as a center hole filter such as the first segment 25.

The wrapper 28 is wound in a cylindrical shape on the outside of the tobacco rod portion 20A, the connecting portion 20B, and the filter portion 20C, and these are integrally connected. A vinyl acetate emulsion-based adhesive is applied to one surface (inner surface) of the wrapper 28 on the entire surface or substantially the entire surface except the vicinity of the ventilation hole portion 24. The plurality of ventilation holes 24 are formed by laser processing from the outside after the tobacco rod portion 20A, the connecting portion 20B, and the filter portion 20C are integrated by the wrapper 28.

The ventilation hole portion 24 has two or more through holes so as to penetrate the connecting portion 20B in the thickness direction. The two or more through holes are formed so as to be arranged radially when viewed from the extension line of the central axis of the flavor suction article 20. In the present embodiment, the ventilation hole portion 24 is provided in the connecting portion 20B, but may be provided in the filter portion 20C. Further, in the present embodiment, the two or more through holes of the ventilation hole portion 24 are provided side by side in a row at regular intervals on one ring, but at regular intervals on the two rings. The vent holes 24 in one row or two rows may be provided side by side in two rows, or the ventilation holes 24 in one row or two rows may be provided side by side in a discontinuous or irregular manner. When the user holds the mouthpiece and sucks it, the outside air is taken into the mainstream smoke through the ventilation hole portion 24. However, the ventilation hole portion 24 may not be provided.

<Definition>
The swellability is a numerical value calculated from the height of a tobacco-engraved cylinder obtained after applying a load of 11.4 kg for 5 seconds in a measuring cylinder having a diameter of 95 mm in which a sample is placed. In other words, it represents the volume per unit weight when the block of ticks is compressed with a constant force.
FP = (A × h5) / W [cm ³ / 100g]
FP: Bulkiness A: Cross-sectional area of the tobacco carved cylinder W: Weight of the tobacco carved h5: Height of the tobacco carved cylinder at the end of the load

[Comparative Example 1]
The reconstructed tobacco sheet (name: sheet 1) was stamped using a stamping machine (manufactured by Hauni, name KT2L) with a stamping width of 0.8 mm. The length of the engraving after cutting varied, but was in the range of approximately 5.0 mm to 30.0 mm. Moisture measurement and bulkiness measurement of the reconstructed tobacco sheet after stamping were performed. In the water content measurement, the weight loss when stored in an oven at 105 ° C. for 1 hour was calculated as the water content loss.
The results are shown below.
Moisture: 13.7 [% by weight]
Bulkiness: 303 [cm ³ / 100g]

[Comparative Example 2]
Except for changing the type of the reconstructed tobacco sheet to sheet 2, stamping was performed in the same manner as in Comparative Example 1 to evaluate the bulkiness. The results are shown below.
The results are as follows;
Moisture: 13.2 [% by weight]
Bulkiness: 342 [cm ³ / 100g]

[Example 1]
<Humidification>
The reconstructed tobacco sheet (name: sheet 1) is placed in a cylinder-type container (inner diameter 0.9 m, length 2.0 m) equipped with a water supply device, a heating device, and a rotating device, and steam is added to humidify the sheet. Was done. The product temperature of the reconstructed tobacco sheet at this time was about 50 to 70 ° C. When steam and hot water were added, exhaust was performed from the cylinder. The moisture content of the reconstituted tobacco sheet after humidification was 18.0% by weight.

<Stamping>
The humidified tobacco sheet was cut using a cutting machine (manufactured by Hauni, named KT2L) with a cutting width of 0.8 mm. The length of the engraving after cutting varied, but was in the range of approximately 5.0 mm to 30.0 mm. The water content was 18.0% by weight.

<Drying>
The tobacco sheet after cutting was dried using an air flow dryer. An airflow dryer (Garbuio / Dickinson, named EVA Dryer 400) was used.

<Evaluation>
Moisture measurement and bulkiness measurement of the reconstructed tobacco sheet after air flow drying were performed. In the water content measurement, the weight loss when stored in an oven at 105 ° C. for 1 hour was calculated as the water content loss. The results are shown below.
Moisture: 13.3 [% by weight]
Bulkiness: 354 [cm ³ / 100g]

[Example 2]
The reconstructed tobacco sheet was stamped by the same method as in Example 1 except that the type of the reconstructed tobacco sheet was changed to sheet 2, and the bulkiness was evaluated. The results are shown below.
Moisture: 13.2 [% by weight]
Bulkiness: 371 [cm ³ / 100g]
The above results are summarized in the table below.

Both types of the reconstructed tobacco sheet produced by the method of the present invention had higher swelling property than the reconstructed tobacco sheet produced in the comparative example. Since the value of swelling property is strongly influenced by the shape of tobacco at the time of measuring swelling property, in this example, all the shapes of tobacco carvings are the same. In addition, since the water content during tobacco cutting also affects the swelling property, in this example, the water content of the tobacco cutting is made to be the same as much as possible. As an empirical formula (empirical formula), there is a correction formula that corrects the moisture content of tobacco in terms of bulkiness, but in this example, the difference in water content at each level is small, and it was judged that the water content correction is unnecessary.
