Description

Technical Field

[0001] This invention relates to tobacco blends for tobacco sheets and methods for producing the same; tobacco sheets and methods for producing the same; heated non-burning flavor inhalers; and heated non-burning flavor inhalation systems. Background Technology

[0002] Flavor is obtained from a combustible flavor inhaler (cigarette) by burning a tobacco filling material containing tobacco leaves. Heated-non-burning flavor inhalers have been proposed as an alternative to combustible flavor inhalers, where flavor is obtained by heating rather than burning the flavor source (e.g., tobacco sheet). For example, PTL 1 discloses a method for producing tobacco sheet in which a first composition comprising a first binder and an aerosol forming agent and a second composition comprising tobacco material, filler, and optionally a second binder are combined to form a mixture of the first and second compositions, and the mixture is extruded to form a sheet of aerosol-generating material.

[0005] PTL 1: WO 2022 / 096860 A1 Summary of the Invention

[0006] The problem to be solved by the present invention

[0007] However, when tobacco blends (the starting materials for tobacco sheets) are produced using conventional methods, agglomerates are easily formed, resulting in a lack of uniformity and potential stickiness. Therefore, when tobacco blends obtained through conventional methods are used to produce tobacco sheets, especially via rolling, production efficiency may decrease, and the uniformity of the resulting tobacco sheets may also decline. Furthermore, conventional methods may require a longer production time for the tobacco blends.

[0008] Therefore, the object of the present invention is to provide a method for producing a tobacco mixture for tobacco sheets, the method enabling the production of a tobacco mixture for tobacco sheets with fewer agglomerates, uniformity and low viscosity in a short time, and also to provide a method for producing tobacco sheets, the method comprising the above method.

Detailed Implementation

[0047] [Method for producing tobacco blends for tobacco sheets]

[0048] The method for producing a tobacco mixture for tobacco sheets according to this embodiment includes the following steps: shearing a sheet starting material in a mixer having a rotatable first blade by means of the rotation of the first blade, the sheet starting material including tobacco raw material, binder, water and aerosol source.

[0049] In the method according to this embodiment, a sheet starting material comprising tobacco raw material, binder, water, and aerosol source is sheared and mixed by rotating a first blade disposed within a mixer. The term "shear mixing" as used in this specification means that the sheet starting material is mixed while the first blade is rotating and cutting (mixing is achieved through the shear force generated by the rotating blade). In the method according to this embodiment, by rotating the first blade to shear and mix the sheet starting material, large-volume particle agglomerates are moved to the lower region of the mixer, where the agglomerates are sheared and refined and dispersed in a short time. Therefore, the resulting tobacco mixture for tobacco sheets contains fewer agglomerates, is homogeneous, and has low viscosity.

[0050] Sheet starting materials include tobacco raw materials, binders, water, and aerosol sources. Sheet starting materials may also include other components besides tobacco raw materials, binders, water, and aerosol sources. Examples of other components that may be cited include pulp, flavoring components, and fillers.

[0051] Whole tobacco or parts of tobacco can be used as tobacco raw materials, and the parts of tobacco that can be used include leaves, veins, stems, roots, flowers, and mixtures thereof. There are no particular restrictions on the variety of tobacco raw materials, but examples that can be used include flue-cured tobacco, burley tobacco, local varieties of tobacco, and oriental tobacco, etc. These can be used alone or in combination of two or more. The tobacco raw materials used can be in a fresh leaf state that is not yet dried immediately after harvest, or they can be materials that have been dried and aged after harvest, or combinations thereof can be used. In addition, tobacco midrib or expanded tobacco obtained by processing the above-mentioned tobacco raw materials can also be used. These tobaccos can be used alone, or several types of varieties or parts can be used in combination. In addition, tobacco extracts obtained by extracting these tobacco raw materials using proton or non-proton solvents can also be used as tobacco raw materials. The content of tobacco raw materials included in the sheet starting material is preferably 50% to 95% by mass, more preferably 60% to 90% by mass, and even more preferably 70% to 80% by mass. It should be noted that the percentage content indicates the mass percentage of tobacco raw materials relative to 100% by mass of sheet starting material (excluding water). This also applies to the percentage content of the other components (excluding water) given below.

[0052] The sheet starting material includes an adhesive that binds the components forming the sheet starting material together. Polysaccharide thickeners may be used as adhesives. Suitable polysaccharide thickeners include starches, such as pregelatinized corn starch and hydroxypropyl potato starch; carboxymethyl cellulose (CMC); and pullulan. These may be used alone or in combination of two or more. The content of the adhesive included in the sheet starting material is preferably 1% to 20% by mass, more preferably 3% to 15% by mass, and even more preferably 5% to 10% by mass.

[0053] In this specification, "aerosol source" refers to a component that generates an aerosol vaporization component when heated, which is then cooled to thereby generate an aerosol. Aerosol sources that may be cited include polyols and triacetin esters, etc. Examples of polyols that may be cited include glycerol, propylene glycol, sorbitol, xylitol, erythritol, and 1,3-butanediol. These can be used alone or in combination of two or more. The content of the aerosol source included in the sheet starting material is preferably 1% to 30% by mass, more preferably 5% to 25% by mass, and even more preferably 10% to 20% by mass.

[0054] The sheet starting material according to this embodiment includes water. To achieve the advantageous effect of good formability, when the resulting tobacco mixture for tobacco sheets is rolled to produce tobacco sheets, the moisture content of the sheet starting material is preferably 45% by mass or less, more preferably 10% by mass to 40% by mass, even more preferably 20% by mass to 40% by mass, and particularly preferably 25% by mass to 35% by mass. When the tobacco mixture for tobacco sheets is rolled to produce tobacco sheets (laminated sheets or rolled sheets), the sheet starting material used has a lower moisture content than when tobacco sheets (paper sheets or cast sheets) are produced using normal papermaking or casting methods. Sheet starting materials with lower moisture content are difficult to mix, which therefore makes it more difficult to obtain a uniform tobacco mixture for tobacco sheets. The method according to this embodiment makes it possible to obtain a uniform tobacco mixture for tobacco sheets, which is particularly effective when using sheets with such low moisture content. It should be noted that the percentage moisture content indicates the percentage of water contained in the sheet starting material relative to the total mass of 100% of the sheet starting material.

[0055] The sheet starting material according to this embodiment may contain pulp as a tobacco sheet reinforcing agent. When the sheet starting material includes pulp, the pulp content in the sheet starting material is preferably 1% to 20% by mass, more preferably 3% to 15% by mass, and even more preferably 5% to 10% by mass.

[0056] From the perspective of imparting flavor to tobacco sheets, the starting material of the sheet according to this embodiment may include flavoring components. In this specification, "flavoring component" refers to a flavoring component other than tobacco components. There are no particular limitations on the type of flavoring component, and flavoring agents, taste materials, and cooling agents can be cited as examples. The nature of the flavoring component is not critical, and examples such as solid and liquid can be cited. Furthermore, a single component may be used, or multiple components may be combined.

[0057] Examples of flavoring agents selected from the following can be used alone or in combination as suitable flavoring agents: tobacco extracts and tobacco components, sugar-containing and sugar-based flavoring agents, licorice (Glycyrrhiza glabra), cocoa, chocolate, fruit juices and fruits, seasonings, alcoholic beverages, herbs, vanilla, and flower-based flavoring agents, etc.

[0058] Flavoring agents can employ a wide range of flavoring components, as disclosed in, for example, the following publications: “Published Collection of Well-Known Prior Arts (Flavor and Fragrance)” (March 14, 2007, JPO); “Saishin Koryo noJiten [Encyclopedia of Scents – Latest Edition] (popular edition)” (February 25, 2012, edited by Soichi ARAI, Akio KOBAYASHI, Izumi YAJIMA, and Michiaki KAWASAKI, Asakura Publishing Co., Ltd.); and “Tobacco Flavoring for Smoking Products” (June 1972, RJ REYNOLDS TOBACCO COMPANY).

[0059] Flavoring agents selected from the following categories may be cited individually or in combination as examples of flavoring agents: isothiocyanates, indoles and their derivatives, ethers, esters, ketones, fatty acids, aliphatic higher alcohols, aliphatic higher aldehydes, aliphatic higher hydrocarbons, thioethers, thiols, terpenes, phenolic ethers, phenols, furfural and its derivatives, aromatic alcohols, aromatic aldehydes, and lactones. Flavoring agents can also be components that produce a cooling / warming sensation.

[0061] Components exhibiting sweetness, sourness, saltiness, umami, bitterness, astringency, fullness, spiciness, irritation, and astringency can be cited as examples of taste materials. Sugars, sugar alcohols, and sweeteners can be listed as examples of components exhibiting sweetness. Monosaccharides, disaccharides, oligosaccharides, and polysaccharides can be listed as examples of sugars. Natural and synthetic sweeteners can be listed as examples of sweeteners. Organic acids (and their sodium salts) can be listed as examples of components exhibiting sourness. Acetic acid, adipic acid, citric acid, lactic acid, malic acid, succinic acid, and tartaric acid can be listed as examples of organic acids. Caffeine (extract), naringin, and wormwood extract can be listed as examples of components exhibiting bitterness.

[0062] When the sheet starting material includes a flavoring component, the content of the flavoring component included in the sheet starting material is typically 10,000 ppm by mass or more, preferably 20,000 ppm by mass or more, and more preferably 25,000 ppm by mass or more, and typically 70,000 ppm by mass or less, preferably 50,000 ppm by mass or less, more preferably 40,000 ppm by mass or less, and even more preferably 33,000 ppm by mass or less.

[0063] The sheet starting material according to this embodiment may include fillers. Examples of fillers that may be cited include calcium carbonate, titanium dioxide, and kaolin. These may be used alone or in combination of two or more. When the sheet starting material includes fillers, the filler content in the sheet starting material may be from 10% by mass to 60% by mass, and preferably from 15% by mass to 45% by mass.

[0064] The components of the sheet starting material described above can be introduced entirely into the mixer at the beginning, and the sheet starting material can be shear-mixed, or the components of the sheet starting material can be introduced into the mixer sequentially and then shear-mixed. Particularly preferred is that the liquid and solid starting materials are premixed separately, and then the resulting liquid and solid mixtures are shear-mixed within the mixer, as this allows for a more uniform mixing of the sheet starting material components, enabling the production of a tobacco mixture for tobacco sheets containing fewer agglomerates and being more homogeneous. That is, the method according to this embodiment preferably further includes: a step of mixing a liquid starting material comprising water and an aerosol source to obtain a liquid mixture, and a step of mixing a solid starting material comprising tobacco raw materials and a binder to obtain a solid mixture, and then shear-mixing the liquid and solid mixtures within the mixer by rotating a first blade. For example, preferably, a liquid starting material comprising water and an aerosol source is premixed to prepare a liquid mixture separately, and a solid starting material comprising tobacco raw material and a binder is mixed in a mixer to prepare a solid mixture. The liquid mixture is then introduced into the mixer, and the liquid and solid mixtures are sheared and mixed by the rotation of a first blade. It should be noted that the binder can be added to the liquid starting material, or the binder can be added to both the liquid and solid starting materials.

[0065] There are no particular limitations on the mixer used in the method according to this embodiment, provided that the mixer includes a rotatable first blade. The first blade is preferably disposed on the inner bottom surface of the mixer because this allows the sheet starting material to circulate within the mixer, thereby enabling more efficient shear mixing of the sheet starting material. There are no particular limitations on the shape of the first blade; it can be a plate-shaped blade, such as a rectangular blade or a cross-shaped blade. There are no particular limitations on the number of first blades; there can be one, two, or more first blades. When there are two or more first blades, the plurality of first blades can be arranged in a stacked manner on the inner bottom surface of the mixer.

[0066] There are no particular limitations on the size of the mixer or the first blade. The mixer can have a capacity of, for example, 10 L to 30 L. The mixer can have an inner diameter of, for example, 100 mm to 600 mm. The mixer can have an internal depth of, for example, 100 mm to 600 mm. The span (maximum length) of the first blade can be, for example, 100 mm to 600 mm. Furthermore, the mass of the sheet starting material introduced into the mixer depends on the size of the mixer, but can be, for example, 1 kg to 10 kg.

[0067] During the shear mixing of the sheet starting material, the circumferential speed (tangential rotational speed of the first blade) of the first blade is preferably from 50 m / min to 700 m / min, more preferably from 75 m / min to 650 m / min, and even more preferably from 100 m / min to 600 m / min. A circumferential speed of the first blade within this range allows for more efficient shear mixing of the sheet starting material. During the shear mixing of the sheet starting material, the rotational speed per minute (rpm) of the first blade is preferably from 50 rpm to 700 rpm, more preferably from 75 rpm to 650 rpm, and even more preferably from 100 rpm to 600 rpm. A rotational speed per minute of the first blade within this range allows for more efficient shear mixing of the sheet starting material. The shear mixing time of the sheet starting material depends on the mixer performance, but can be, for example, from 60 seconds to 600 seconds.

[0068] The mixer preferably further includes a rotatable second blade on the upper portion of the inner side surface of the mixer. As the sheet starting material is shear-mixed, the rotation of the second blade creates a flow that feeds the sheet starting material located in the upper region of the mixer to the lower region of the mixer. This promotes circulation of the sheet starting material within the mixer, allowing for more efficient shear-mixing of the sheet starting material.

[0069] There are no particular restrictions on the shape of the second blade; it can be a plate-shaped blade, such as a rectangular blade or a cross-shaped blade. There are no particular restrictions on the number of second blades; there can be one, two, or more. When there are two or more second blades, they can be arranged in a stacked manner on the inner side surface of the mixer. There are no particular restrictions on the span (maximum length) of the second blades; this span can be, for example, from 50 mm to 300 mm.

[0070] During the shear mixing of the sheet starting material, the circumferential speed (tangential rotational speed of the second blade) of the second blade is preferably from 75 m / min to 300 m / min, more preferably from 100 m / min to 250 m / min, and even more preferably from 125 m / min to 200 m / min. A circumferential speed of the second blade within this range allows for more efficient shear mixing of the sheet starting material. During the shear mixing of the sheet starting material, the rotational speed per minute (rpm) of the second blade is preferably from 200 rpm to 800 rpm, more preferably from 300 rpm to 700 rpm, and even more preferably from 400 rpm to 600 rpm. A rotational speed per minute of the second blade within this range allows for more efficient shear mixing of the sheet starting material.

[0071] The mixer preferably further includes plate-shaped blades on its inner upper surface. These blades are positioned substantially perpendicular to the inner bottom surface of the mixer and attached to the inner upper surface. The blades may be attached in a direction facing the center of the mixer (the central axis of the mixer lies along the extension line of the plate-shaped blades). When the sheet starting material is shear-mixed, the blades create a flow that feeds the sheet starting material located near the inner side surface of the mixer to the central region of the mixer. This promotes the flow and circulation of the sheet starting material within the mixer, allowing for more efficient shear mixing of the sheet starting material.

[0072] There are no particular restrictions on the shape of the blade, as long as the blade is plate-shaped and can be, for example, a rectangular blade or the like. When the blade is rectangular, the length of one side of the blade (the longer side in the case of a rectangle) can be, for example, 60 mm to 300 mm. In addition, the length from the top surface of the mixer to the lower part of the blade can be, for example, 100 mm to 400 mm.

[0073] [Tobacco blends for use in tobacco sheets]

[0074] The tobacco mixture for tobacco sheets according to this embodiment is produced by the production method of the tobacco mixture for tobacco sheets according to this embodiment. The tobacco mixture for tobacco sheets is uniform and has low viscosity because it is produced by the method according to this embodiment. Therefore, using this tobacco mixture for tobacco sheets, it is particularly possible to efficiently produce uniform tobacco sheets by rolling.

[0075] [Methods for producing tobacco sheets]

[0076] The method for producing tobacco sheets according to this embodiment includes the following steps: a step of producing a tobacco mixture for tobacco sheets by means of the method of this embodiment; and a step of producing tobacco sheets by using such a tobacco mixture for tobacco sheets. In the method for producing tobacco sheets according to this embodiment, the tobacco mixture for tobacco sheets is produced by means of the method of this embodiment, thus enabling the production of a tobacco mixture for tobacco sheets with fewer agglomerates, uniformity, and low viscosity in a short time. Therefore, uniform tobacco sheets can be produced efficiently. The above effect is even more pronounced when the step of producing tobacco sheets includes: a step of extruding the tobacco mixture for tobacco sheets to obtain a sheet extrudate, and a step of rolling the sheet extrudate to obtain tobacco sheets (i.e., when tobacco sheets are produced by a rolling process).

[0077] A method including the following steps can be cited as an example of a method for producing tobacco sheets by means of a rolling process.

[0078] (1) The step of extruding a tobacco mixture for use in tobacco sheets to obtain a sheet extrusion;

[0079] (2) The step of feeding the sheet extrusion between the rollers to roll the sheet extrusion; and

[0080] (3) The step of drying the rolled product in a dryer.

[0081] When producing tobacco sheets using this method, the surface of the rollers can be heated or cooled as needed, and the rotational speed of the rollers can be adjusted. The gap between the rollers can also be adjusted. One or more rollers can be used to obtain tobacco sheets with the desired basis weight.

[0083] The tobacco sheet according to this embodiment is produced by the method for producing tobacco sheets according to this embodiment. The tobacco sheet is uniform because it is produced by the method according to this embodiment. This uniformity of the tobacco sheet enables stable product quality, thereby allowing for a continuous and stable flavor delivery to the user when the tobacco sheet is used in a heated, non-burning flavor inhaler, as will be described later. The sheet also has high strength because the binder is uniformly mixed.

[0084] [Heated Flavor Inhaler]

[0085] The heated non-burning flavor inhaler according to this embodiment includes a tobacco-containing segment, which includes tobacco sheet according to this embodiment. Figure 1 An example of a heated, non-burning flavor inhaler according to this embodiment is shown. Figure 1 The heated non-burning flavor inhaler 1 shown includes: a tobacco-containing section 2 filled with tobacco sheet or the like according to this embodiment; a cylindrical cooling section 3 having circumferential perforations 8; a central perforation section 4; and a filter section 5. In addition to the tobacco-containing section, cooling section, central perforation section, and filter section, the heated non-burning flavor inhaler according to this embodiment may also have other sections.

[0086] There is no particular limitation on the axial length of the heated non-burning flavor inhaler according to this embodiment, but the axial length is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and even more preferably 50 mm to 60 mm. Furthermore, the circumferential length of the heated non-burning flavor inhaler is preferably 16 mm to 25 mm, more preferably 20 mm to 24 mm, and even more preferably 21 mm to 23 mm. In an exemplary aspect, the length of the tobacco section is 20 mm, the length of the cooling section is 20 mm, the length of the central hole section is 8 mm, and the length of the filter section is 7 mm. It should be noted that the length of the filter section can be selected from the range of 4 mm to 10 mm. Furthermore, the length can be selected such that the airflow resistance of the filter section is between 15 mmH2O / section and 60 mmH2O / section. For example, the lengths of these individual sections can be appropriately modified according to manufacturability and desired quality. The function of the heated non-burning flavor inhaler can still be achieved if only the filter section is located downstream of the cooling section without using the central hole section.

[0087] (Including tobacco section)

[0088] The tobacco-containing segment 2 includes a wrapping paper (hereinafter also referred to as "wrapping material") that contains tobacco sheets or the like according to this embodiment. There are no particular limitations on the method of wrapping tobacco sheets or the like with the wrapping paper, but the tobacco sheets or the like can be enclosed in the wrapping material, or a cylindrical wrapping material can contain the tobacco sheets or the like. When the tobacco sheet has a longitudinal shape (e.g., a rectangular shape), the tobacco sheet or the like can be wrapped inside the wrapping material such that its longitudinal direction is randomly oriented, or it can be wrapped such that its longitudinal direction is oriented in the axial direction of the tobacco-containing segment 2 or in a direction perpendicular to it.

[0089] (Cooling section)

[0090] like Figure 1 As shown, the cooling section 3 can be formed by a cylindrical member 7. The cylindrical member 7 can be, for example, a paper tube obtained by processing cardboard into a cylindrical shape. The cylindrical member 7 and the mouthpiece liner 12, described later, are provided with perforations 8 penetrating both. The perforations 8 allow outside air to be introduced into the cooling section 3 during inhalation. Therefore, the aerosol vaporized component generated by heating the tobacco-containing section 2 is liquefied because the aerosol vaporized component comes into contact with outside air, causing its temperature to drop and forming an aerosol. There is no particular limitation on the diameter (span) of the perforations 8, but the diameter can be, for example, from 0.5 mm to 1.5 mm. There is no particular limitation on the number of perforations 8; there can be one, two, or more perforations. For example, multiple perforations 8 can be provided on the circumference of the cooling section 3.

[0091] The amount of outside air introduced through the perforation 8 is preferably 85 vol% or less, and more preferably 80 vol% or less, relative to the total volume of gas inhaled by the user. An outside air proportion of up to 85 vol% will sufficiently limit flavor reduction caused by outside air dilution. It should be noted that this is also referred to as the ventilation ratio. From a cooling perspective, the lower limit of the ventilation ratio range is preferably 55 vol% or more, and more preferably 60 vol% or more.

[0092] Furthermore, the cooling section can also be a segment of a sheet of material comprising pleats, folds, gathers, or folds. The cross-sectional profile of such an element can exhibit randomly oriented channels. Additionally, the cooling section can include a bundle of longitudinally extending tubes. Such a cooling section can be formed, for example, by wrapping pleated, gathered, or folded sheets with wrapping paper.

[0093] The axial length of the cooling section can be from 7 mm to 28 mm, and can be, for example, 18 mm. In addition, the cooling section can be substantially circular in its axial cross-sectional shape, with a diameter of, for example, 5 mm to 10 mm, and can be, for example, about 7 mm.

[0094] (Central hole segment)

[0095] The central hole segment is formed by a filling layer having one or more hollow portions and an inner core covering the filling layer (internal wrapping paper). For example... Figure 1 As shown, for example, the central hole segment 4 is formed by a filling layer 9 having a hollow portion and an inner core covering 10 covering the filling layer 9. The central hole segment 4 functions to increase the strength of the suction nozzle segment 6. The filling layer 9 can be formed, for example, as a rod with an inner diameter of φ1.0 mm to φ5.0 mm, packed with high-density cellulose acetate fibers, wherein a plasticizer containing triacetin is added, the amount of which is 6% to 20% by mass relative to the mass of cellulose acetate, and the plasticizer is cured. The filling layer 9 has high bulk density fibers, so air and aerosols flow only through the hollow portion during suction and hardly through the filling layer 9. The filling layer 9 inside the central hole segment 4 is a fiber filling layer, so the user will hardly feel any discomfort when touching the outside during use. In addition, the shape of the central hole segment 4 can also be maintained by thermoforming without the need for the inner core covering 10.

[0096] (Filtering section)

[0097] There are no particular restrictions on the configuration of filter section 5, but it can be formed by a single filling layer or multiple filling layers. The outer side of the filling layer can be wrapped with one or more sheets of wrapping paper. The airflow resistance of each section of filter section 5 can be appropriately changed by the amount and material of the filling material. For example, when the filling material is cellulose acetate fiber, the airflow resistance can be increased by increasing the amount of cellulose acetate fiber filling filter section 5. When the filling material is cellulose acetate fiber, the bulk density of cellulose acetate fiber can be 0.13 g / cm³. 3 Up to 0.18 g / cm 3 It should be noted that the airflow resistance is measured using an airflow resistance meter (trade name: SODIMAX, manufactured by SODIM).

[0098] There are no particular limitations on the circumferential length of the filter section 5, but it is preferably 16 mm to 25 mm, more preferably 20 mm to 24 mm, and even more preferably 21 mm to 23 mm. The axial length of the filter section 5 can be selected from 4 mm to 10 mm, and the axial length is chosen such that the airflow resistance is 15 mmH2O / section to 60 mmH2O / section. The axial length of the filter section 5 is preferably 5 mm to 9 mm, and more preferably 6 mm to 8 mm. There are no particular limitations on the cross-sectional shape of the filter section 5, but the cross-sectional shape can be, for example, circular, elliptical, or polygonal. Furthermore, easily broken capsules, flavor beads, or flavor materials containing flavoring agents can be directly added to the filter section 5.

[0099] like Figure 1 As shown, the central hole segment 4 and the filter segment 5 can be connected by an outer core wrapping material (outer wrapping paper) 11. For example, the outer core wrapping material 11 can be a cylindrical paper. Furthermore, the central hole segment 4 containing the tobacco segment 2, the cooling segment 3, and the connecting central hole segment 4, as well as the filter segment 5, can be connected by means of a mouthpiece liner 12. These connections can be formed, for example, by coating the inner surface of the mouthpiece liner 12 with adhesive (such as vinyl acetate-based adhesive), inserting the aforementioned three segments therein, and wrapping these segments with the mouthpiece liner. It should be noted that these segments can also be connected to multiple liners via multiple individual connectors.

[0100] [Heated but not burning flavor inhalation system]

[0101] The heated non-burning flavor inhalation system according to this embodiment includes: a heated non-burning flavor inhaler according to this embodiment, and a heating device for heating the tobacco segment of the heated non-burning flavor inhaler. The heated non-burning flavor inhalation system according to this embodiment may have components other than the heated non-burning flavor inhaler and the heating device according to this embodiment.

[0102] Figure 2 An example of a heated, non-burning flavor inhalation system according to this embodiment is shown. Figure 2 The heated non-burning flavor inhalation system shown includes: a heated non-burning flavor inhaler 1 according to this embodiment; and a heating device 13 for externally heating the tobacco-containing segment of the heated non-burning flavor inhaler 1.

[0103] Figure 2 (a) shows the state of the heated non-burning flavor inhaler 1 before it is inserted into the heating device 13, and Figure 2 (b) shows the state in which the heated non-burning flavor inhaler 1 is inserted into the heating device 13 for heating. Figure 2 The heating device 13 shown includes a body 14, a heater 15, a metal tube 16, a battery unit 17, and a control unit 18. The body 14 includes a cylindrical recess 19, and the heater 15 and the metal tube 16 are disposed on the inner side surface of the recess 19, at a position corresponding to the tobacco-containing segment in the insertion recess 19 of the heated non-burning flavor inhaler 1. The heater 15 may be a resistive heater, wherein the battery unit 17 supplies power according to commands from the control unit 18 that controls the temperature, causing the heater 15 to heat up. The heat emitted from the heater 15 is transferred to the tobacco-containing segment of the heated non-burning flavor inhaler 1 through the metal tube 16, which has high thermal conductivity.

[0104] Figure 2(b) is a schematic diagram showing a gap between the outer periphery of the heated non-burning flavor inhaler 1 and the inner periphery of the metal tube 16. However, for the purpose of efficient heat transfer, it is preferable that there is no gap between the outer periphery of the heated non-burning flavor inhaler 1 and the inner periphery of the metal tube 16. It should also be noted that the heating device 13 heats the tobacco-containing section of the heated non-burning flavor inhaler 1 from the outside, but the tobacco-containing section can also be heated from the inside.

[0105] There are no particular limitations on the heating temperature generated by the heating device, but the temperature is preferably 400°C or lower, more preferably 150°C to 400°C, and even more preferably 200°C to 350°C. It should be noted that the heating temperature indicates the temperature of the heater in the heating device.

[0106] Example

[0107] The embodiments will be described in detail below by way of examples, but the embodiments are not limited to those examples.

[0108] [Example 1]

[0109] Prepare the mixer. The mixer has a capacity of 20 L, an inner diameter of 340 mm, and an internal depth of 310 mm. The mixer includes a rotatable first blade on its inner bottom surface. The first blade is plate-shaped, with four rectangular blades arranged in a stacked configuration, spanning (maximum length) of 315 mm. Furthermore, the mixer includes a rotatable second blade on the upper portion of its inner side surface. The second blade is plate-shaped, with three rectangular blades arranged in a stacked configuration, spanning (maximum length) of 120 mm. The mixer further includes a plate-shaped blade on its inner upper surface. This blade is positioned substantially perpendicular to the inner bottom surface of the mixer and attached to the inner upper surface. The blade is attached in a direction facing the center of the mixer (the central axis of the mixer lies on the extension line of the plate-shaped blade). The blade is square, with one side having a length of 120 mm. The length from the top surface of the mixer to the lower portion of the blade is 190 mm.

[0110] The following materials were prepared as starting materials for the sheet: 76 parts by mass of tobacco leaves (flue-cured / Oriental tobacco blend), 12 parts by mass of glycerol, 6 parts by mass of carboxymethyl cellulose (CMC) as a binder, 6 parts by mass of pulp, and water. The total mass of the sheet was 5 kg. Water was also prepared in an amount such that the total water content of the starting materials was 30% by mass. Glycerol and water were mixed in separate containers to obtain a liquid mixture. Simultaneously, the tobacco leaves, binder, and pulp were introduced into a mixer and sheared and mixed by the rotation of the first and second blades to obtain a solid mixture. During this process, the circumferential speed of the first blade was 594 m / min (600 rpm), the circumferential speed of the second blade was 188 m / min (500 rpm), and the mixing time was 180 seconds.

[0111] Following this, mixing and shearing are performed while the liquid mixture is introduced into a mixer containing the solid mixture over a 60-second time period. During this process, the circumferential speed of the first blade is 99 m / min (100 rpm), and the circumferential speed of the second blade is 188 m / min (500 rpm). After all the liquid mixture has been introduced, mixing and shearing are performed by rotating the first and second blades to obtain a tobacco mixture for tobacco sheets. During this process, the circumferential speed of the first blade is 594 m / min (600 rpm), the circumferential speed of the second blade is 188 m / min (500 rpm), and the mixing time is 180 seconds. The resulting tobacco mixture for tobacco sheets contains fewer agglomerates, is homogeneous, and has low viscosity.

[0112] [Comparison Example 1]

[0113] Prepare a can consisting of a rotatable kneader and a rotatable mixing container. The can has a capacity of 50 L, an inner diameter of 450 mm, and an internal depth of 360 mm. The can includes two rotatable kneaders attached to the upper inner surface of the can and arranged to extend from the upper inner surface just below the lower surface. Each kneader is a rod-shaped member twisted 180°, and the two kneaders are capable of rotating in opposite directions. Each kneader has a longitudinal length of 360 mm, a thickness of 30 mm, and a maximum width of 125 mm at the twisted section (the maximum distance between the opposing portions of the rods in the twisted section, i.e., the width of the kneader). Furthermore, the can includes a rotatable cylindrical mixing container that forms the inner wall of the can and contains the sheet starting material.

[0114] The following materials were prepared as starting materials for the sheet: 76 parts by weight of tobacco leaves (flue-cured / Oriental tobacco blend), 12 parts by weight of glycerol, 6 parts by weight of carboxymethyl cellulose (CMC) as a binder, 6 parts by weight of pulp, and water. The total mass of the sheet was 20 kg. Water was also prepared in an amount such that the total moisture content of the starting materials was 30% by weight. Glycerol and water were mixed in separate containers to obtain a liquid mixture. Simultaneously, tobacco leaves, binder, and pulp were introduced into a tank, and a kneader and mixing container were rotated to perform kneading without applying shear, resulting in a solid mixture. During this process, the kneader's circumferential speed was 98 m / min (250 rpm), the mixing container's circumferential speed was 21 m / min (15 rpm), and the mixing time was 300 seconds.

[0115] Following this, kneading is performed without shearing, while the liquid mixture is introduced into a container containing the solid mixture over a 60-second time period. During this process, the kneader's circumferential speed is 98 m / min (250 rpm), and the mixing container's circumferential speed is 21 m / min (15 rpm). After all the liquid mixture has been introduced, kneading is performed again without shearing by rotating the kneader and mixing container to obtain a tobacco mixture for tobacco sheets. During this process, the kneader's circumferential speed is 98 m / min (250 rpm), the mixing container's circumferential speed is 21 m / min (15 rpm), and the mixing time is 300 seconds.

[0116] In this comparative example, no shearing is applied when mixing the starting materials for the tobacco sheet, thus requiring a longer mixing time to obtain a homogeneous tobacco mixture with fewer agglomerates. Therefore, it is not possible to produce a tobacco mixture for tobacco sheets with fewer agglomerates, greater homogeneity, and lower viscosity in a shorter time.
