In the example shown in FIG. 1, each tobacco strand 23 is mutually parallelly arrange|positioned along the long-axis direction of the tobacco rod 2. As shown in FIG. In addition, each tobacco strand 23 is extended and arrange|positioned from the front end surface 2a of the tobacco rod 2 to the rear end surface 2b. In addition, the code|symbol 25 shown in FIG. 1 is an aerosol flow path formed by the clearance gap between each tobacco strand 23 comrades. In this embodiment, since each tobacco strand 23 is arranged parallel to each other along the long axis direction of the tobacco rod 2 , for example, the aerosol flow path 25 extends along the long axis direction of the tobacco rod 2 . formed to do

Here, although the detail of the manufacturing method of the tobacco strand 23 and the tobacco rod 2 provided with this is mentioned later, for example, the tobacco raw material obtained by shape|molding the tobacco raw material containing an aerosol generating base material into a sheet shape. It can be obtained by cutting the sheet by slitting it with a slitter or the like. The tobacco raw material sheet may be a so-called reconstituted tobacco sheet. The reconstituted tobacco sheet is, for example, homogenized tobacco by adding a binder, a gelling agent, a crosslinking agent, a flavoring agent, a viscosity modifier, a humectant, a reinforcing material, etc. method), a casting method (slurry method), a rolling method, or an extrusion method may be used to form and dry the sheet into a sheet shape. Homogenized tobacco is, for example, a tobacco material obtained by pulverizing, grinding, and mixing leaf tobacco, dried tobacco leaves, lean tobacco, expanded tobacco, reconstituted tobacco, and the like.

Next, the mouthpiece part 3 is demonstrated. The support part 4 is a segment located in the front end side of the mouthpiece part 3, and located in the connection end where the mouthpiece part 3 is connected with the tobacco rod 2. As shown in FIG. The support part 4 is located just downstream of the tobacco rod 2, and is arrange|positioned in the state which contact|abutted with the rear end of the tobacco rod 2. The support part 4 may be a hollow cellulose acetate tubular body, for example. In other words, the support part 4 may be formed through a center hole in the center of the cross section of the cylindrical cellulose acetate fiber bundle. In addition, the support part 4 may be a paper filter filled with cellulol fiber, a paper tube, etc. as another form. As long as it is a paper tube having a certain thickness, it can function effectively as the support part 4 . The support part 4 is a cooling part 5 in the heating cigarette 1 when the electric heater of the heating device to which the heated cigarette 1 is applied is inserted into the cigarette rod 2, the cigarette filling material 21 in the heating cigarette 1 ) to prevent it from being pushed downstream. Moreover, the support part 4 also functions as a spacer for separating the cooling part 5 of the heated cigarette 1 from the tobacco rod 2 .

The cooling unit 5 is located immediately downstream of the supporting unit 4 , and is disposed in contact with the rear end of the supporting unit 4 . In use of the heated cigarette 1 , the volatile substances emitted from the tobacco rod 2 (tobacco filling material 21 ) flow along the cooling section 5 toward the downstream side. The volatiles emitted from the tobacco rod 2 (tobacco filling 21 ) are cooled in the cooling section 5 , thereby forming an aerosol that is inhaled by the user. In the form shown in FIG. 1, the cooling part 5 is formed by the hollow branch pipe which has the ventilation hole 5a which can introduce|transduce external air. However, the cooling part 5 does not need to have the ventilation hole 5a. Moreover, the cooling part 5 may have the heat absorbing agent arrange|positioned so that the flow of a volatile substance and an aerosol may not be obstructed. For example, the cooling unit 5 may be formed of a filter material in which a plurality of flow paths (through holes) are formed along the longitudinal direction (axial direction) of the mouthpiece unit 3 .

The filter part 6 is a segment located at the rear end of the mouthpiece part 3, that is, the inlet end 1a side.

The heating device 100 includes a case (

) has a housing 102 . In the housing 102 , an electric heater 103 , a controller (control unit) 104 , a power source 105 , and the like are housed. The housing 102 has an accommodation cavity 107 including an opening 106 into which the tobacco rod 2 of the heated cigarette 1 is inserted. The accommodation cavity 107 is a cylindrical hollow part for accommodating the tobacco rod 2, and corresponds to the rod accommodation part in which the tobacco rod 2 can be attached. Further, the present invention may be provided as a heated tobacco product including a heated cigarette 1 and a heating device 100 to which the heated cigarette 1 is applied.

As shown in FIG. 3 , an electric heater 103 is provided in the accommodation cavity 107 . The electric heater 103 shown in FIG. 3 has a cylindrical shape, and protrudes perpendicularly|vertically toward the opening part 106 side from the center part of the bottom part 107a in the accommodation cavity 107, have. However, the shape of the electric heater 103 is not specifically limited. For example, the tip side of the electric heater 103 may be pointed. For example, the electric heater 103 may have a conical shape and may taper gradually toward the front-end|tip side from the base end connected to the bottom part 107a in the accommodation cavity 107. In addition, the electric heater 103 may have a truncated cone shape (truncated cone shape), and may have a blade shape. In addition, the electric heater 103 may have another shape. In addition, the central axis of the electric heater 103 in this embodiment may be coaxial with the central axis of the accommodation cavity 107. As shown in FIG. In addition, the type of the electric heater 103 is not particularly limited, but for example, one in which a heating wire (for example, nichrome, iron chromium, iron nickel, etc.) is wrapped around a steel material, or a ceramic heater; A sheathed heater or the like may be used. Note that the sheath heater is a heater in which a heating wire is wrapped with a metal pipe together with a filler.

The electric heater 103 of the heating device 100 configured as described above is a so-called internal heating type heater. That is, when the tobacco rod 2 is mounted in the accommodation cavity 107 when the heated cigarette 1 is used, the tobacco filler 21 from the front end face 2a side of the tobacco rod 2 in the heated cigarette 1 . ), the electric heater 103 is fitted or inserted, and the cigarette filler 21 is heated from the inside by the electric heater 103 which heats up. The cigarette rod 2 mounted in the accommodation cavity 107 by the controller (control part) 104 being controlled by electricity supply from the power source 105 to the electric heater 103, and the electric heater 103 generating heat. of tobacco filler 21 (tobacco strand 23) is heated. As a result, the aerosol-generating base material contained in the tobacco filler 21 (tobacco strand 23) volatilizes to generate an aerosol, and the aerosol is supplied into the oral cavity of the user who inhales the mouthpiece part 3 .

According to the heated cigarette 1 in this embodiment, each tobacco strand 23 in the tobacco rod 2 is oriented so as to extend along the long axis direction (central axis CL1 direction) of the tobacco rod 2, It is arranged, and each tobacco strand 23 is aligned so as to extend along the long axis direction (central axis CL1 direction) of the tobacco rod 2 . Moreover, in the tobacco rod 2 in this embodiment, the aerosol flow path 25 which is a clearance gap between each tobacco strand 23 comrades is formed so that it may extend|stretch along the long-axis direction of the tobacco rod 2 . Therefore, the aerosol generated by the volatilization of the aerosol generating substrate contained in the tobacco strand 23 during heating by the electric heater 103 can be guided to the mouthpiece 3 through the aerosol flow path 25 . According to this, the aerosol produced|generated by the tobacco rod 2 originates in the contact with the tobacco strand 23, and it becomes difficult to condense, and it becomes difficult to filter by the tobacco strand 23. Therefore, according to the heated cigarette 1 in this embodiment, the delivery amount of the aerosol to the oral cavity of a user can be improved conventionally.

Moreover, according to the heated cigarette 1 in this embodiment, each tobacco strand 23 in the tobacco rod 2 is aligned along the long-axis direction (central axis CL1 direction) of the tobacco rod 2, Therefore, compared with the case where a tobacco raw material is randomly orientated conventionally, the act of fitting or inserting the electric heater 103 from the front-end|tip 1b side of the tobacco rod 2 becomes easy. Thereby, fitting or insertion of the electric heater 103 into the tobacco rod 2 is easy, and it is possible to provide the heated cigarette 1 excellent in usability to a user. As mentioned above, according to the tobacco rod 2 of the heating type cigarette 1 in this embodiment, it is excellent in the delivery amount of an aerosol, Furthermore, the smooth insertion of the electric heater 103 with respect to the tobacco filler 21 is attained. .

In addition, the heating apparatus applied to the heating type cigarette 1 in this embodiment may be equipped with the heater of the external heating type as shown in FIG. 4 instead of the internal heating type as shown in FIG. The heating device 100 shown in FIG. 4 has the same structure as the heating device 100 shown in FIG. 3 except that the electric heater 103 is an external heating type. The electric heater 103 shown in FIG. 4 is an annular external heating type heater formed along the cavity side peripheral wall 107b in the accommodation cavity 107. As shown in FIG. The electric heater 103 shown in FIG. 4 may be arrange|positioned along the cavity side peripheral wall 107A so that it may become coplanar with the cavity side peripheral wall 107b, for example. When the heated cigarette 1 is applied to the heating device 100 provided with the externally heated electric heater 103 as shown in FIG. 4 , when the heated cigarette 1 is used, it is mounted in the accommodation cavity 107 The tobacco filler 21 is heated by the electric heater 103 from the outside of the tobacco rod 2 .

Here, the preferable range of the volume filling factor of the tobacco strand 23 which occupies the tobacco rod 2 is demonstrated. The volume filling ratio of the tobacco strand 23 here refers to the ratio of the total sum of the volumes of all the tobacco strands 23 contained in the tobacco rod 2 with respect to the volume of the tobacco rod 2 . When the volume filling rate of the tobacco strand 23 is too high, we are concerned that the ventilation resistance of the tobacco rod 2 (tobacco filler 21) will become high too much. As a result, the aerosol generated by the tobacco rod 2 during use is filtered (captured) by the tobacco strand 23 in the tobacco rod 2 before being introduced into the mouthpiece portion 3, and the aerosol We are concerned that the amount of delivery decreases. On the other hand, when the volume filling rate of the tobacco strand 23 is too low, the heat transfer efficiency to the tobacco strand 23 at the time of heating by the electric heater 103 will fall, and the delivery amount of an aerosol will decrease. concerned For example, in the case of using the internal heating type electric heater 103 shown in FIG. 3 , in the state where the electric heater 103 is inserted into the tobacco rod 2 , the contact between the electric heater 103 and the tobacco strand 23 is It becomes insufficient, and there exists a possibility that the heating of the tobacco strand 23 may run short.

In view of the above circumstances, the present inventors obtained the knowledge that it is preferable to set the volume filling rate of the tobacco strand 23 which occupies the tobacco rod 2 to 50 vol% or more and 80 vol% or less, as a result of earnest examination. Thereby, it can suppress that the heat transfer efficiency from the electric heater 103 to the tobacco strand 23 falls, suppressing that the ventilation resistance of the tobacco rod 2 (tobacco filler 21) becomes high too much. As a result, it can suppress that the delivery amount of an aerosol decreases at the time of use. Moreover, when the volume filling rate of the tobacco strand 23 is lower than 50 vol%, in addition to the heat transfer efficiency from the electric heater 103 to the tobacco strand 23 falling, the manufacturing aptitude of the tobacco rod 2 will become low. There are concerns. Moreover, when the volume filling rate of the tobacco strand 23 exceeds 80 vol%, it will become difficult to insert the electric heater 103 into the tobacco rod 2, or ventilation resistance will become easy to become high, and an aerosol is midway. There is a possibility that it traps (captures) and reduces the delivery efficiency of the aerosol. For the above reason, it is preferable to make the volume filling rate of the tobacco strand 23 which occupies the tobacco rod 2 into the range of 50 vol% or more and 80 vol% or less.

Here, the preferable range of the volume filling rate of the tobacco strand 23 occupying the tobacco rod 2 is the difference in the heating method of the electric heater 103 of the heating device 100 to which the heated tobacco 1 is applied (internally heated heater) , an externally heated heater). In addition, when the electric heater 103 is an internal heating type, whether the electric heater 103 is in the state inserted in the tobacco rod 2 (the state in which the tobacco rod 2 is attached to the heating apparatus 100) or not. Also, the preferred ranges of the volume filling factor of the tobacco strands 23 are different. For example, when the electric heater 103 of the heating device 100 to which the heated cigarette 1 is applied is an external heating type heater, the volume filling rate of the tobacco strand 23 occupying the tobacco rod 2 is 60 vol% It is preferable that it is 80 vol% or more and 80 vol% or less.

In addition, when the electric heater 103 of the heating device 100 to which the heated cigarette 1 is applied is an internal heating type heater, the volume filling rate of the tobacco strand 23 occupying the tobacco rod 2 is 50 vol% or more and 75 vol% It is preferable that it is below, and it is more preferable to set it as 60 vol%. The volume filling factor up to the above refers to the preferred range of the volume filling factor of the tobacco strand 23 before mounting the tobacco rod 2 in the receiving cavity 107 of the heating device 100 . When the electric heater 103 is an internally heated heater, the electric heater 103 is inserted into the tobacco rod 2 so that the tobacco strands 23 in the tobacco rod 2 are heated by the electric heater 103 into the tobacco rod. (2) is pushed to the outer periphery and expanded. Taking that into consideration, the preferred range (50 vol% or more and 75 vol%) of the volume filling rate of the tobacco strand 23 in the case where the electric heater 103 of the heating device 100 to which the heated cigarette 1 is applied is an internal heating type heater. The following) becomes lower than the preferable range (60 vol% or more and 80 vol% or less) of the volume filling rate of the tobacco strand 23 in the case where the electric heater 103 is an external heating type heater.

In addition, when the electric heater 103 of the heating device 100 to which the heated cigarette 1 is applied is an internal heating type heater, the tobacco rod 2 is mounted in the receiving cavity 107 , that is, the internal heating type heater. It is preferable that the volume filling rate of the tobacco strand 23 in the state inserted into the tobacco rod 2 is 60 vol% or more and 80 vol% or less. Here, the volume filling rate of the tobacco strand 23 in the state where the tobacco rod 2 is attached to the accommodation cavity 107 is the electric heater 103 from the volume of the tobacco rod 2 ) is the ratio of the sum total of the volume of the tobacco strand 23 to the volume calculated by subtracting the volume occupying it.

Moreover, when the volume of the tobacco strand 23 contained in the tobacco rod 2 in this embodiment compares under the same conditions, the one with a larger surface area of the tobacco strand 23 improves the delivery amount of an aerosol. If the width of the individual tobacco strands 23 is large, when the internally heated electric heater 103 is inserted into the tobacco rod 2 , the volume filling rate of the tobacco strands 23 is the cross section of the tobacco rod 2 . It tends to become non-uniform|heterogenous within surface), and there exists a possibility that a difference may become easy to produce in the delivery characteristic of an aerosol. Therefore, from the viewpoint of increasing the delivery amount of the aerosol and making the delivery characteristics of the aerosol uniform, it is preferable to arrange more tobacco strands 23 with a small cross-sectional area on the tobacco rod 2 . However, when the cross-sectional area of the tobacco strand 23 is made small too much, the tensile strength of the tobacco strand 23 will become small too much, and we are concerned about the manufacturability of the tobacco rod 2 falling. Then, from a viewpoint of ensuring all of the improvement of the delivery amount of an aerosol, the uniform delivery of an aerosol, and the improvement of the manufacturing aptitude of the tobacco rod 2 in a balanced way, the width dimension of the cross section in the tobacco strand 23 is 0.4 mm or more It is preferable to set it as 3 mm or less, and it is preferable to make the thickness dimension of the cross section in the tobacco strand 23 into 0.02 mm or more and 1.3 mm or less. In addition, as for the length dimension along the long-axis direction in the tobacco strand 23, the aspect made into 10 mm or more and 50 mm or less is mentioned as an example. Moreover, as mentioned above, since the cross-sectional area of the tobacco strand 23 in this embodiment is uniform over the full length, when heated by the electric heater 103, the long axis of the tobacco strand 23 It becomes difficult to produce a difference in the amount of generation of aerosol in a direction.

Moreover, in this embodiment, although the angular dimension of the tobacco rod 2 is not specifically limited, The length in the long-axis direction of the tobacco rod 2 shall be 10 mm or more and 50 mm or less, and the tobacco rod 2 An example in which the diameter of the cross section orthogonal to the major axis direction of is 5.0 or more and 8.0 mm or less can be exemplified. Moreover, in the heating apparatus 100 to which the heated cigarette 1 is applied, the aspect which sets the maximum diameter of the electric heater 103 to 2.5 mm or more and 3.2 mm or less can be illustrated. And the ratio of the maximum diameter of the electric heater 103 with respect to the diameter of the cross section of the tobacco rod 2 can illustrate the aspect made into 0.3 or more and 0.6 or less. Moreover, the aspect which makes the length of the long-axis direction of the tobacco strand 23 arrange|positioned in the tobacco rod 2 into the dimension substantially the same as the length in the long-axis direction of the tobacco rod 2 is mentioned as an example.

In this way, a plurality of cigarette strand continuums 300 superimposed on the long wrapping web 400 on the garnish belt 1350 are conveyed along the conveying path P by the garnish belt 1350 in the process of being conveyed, in a rod shape. A wrapper web 400 is wound around the outer periphery of the aligned plurality of tobacco strand continuum 300 , and the plurality of tobacco strand continuum 300 is wrapped by the wrapper web 400 . And in the seam formed by the edge portions overlapping each other, the wound web 400 has an adhesive (eg, hot melt adhesive, CMC (carboxymethyl cellulose), PVA (poly vinyl alcohol), EVA (ethylene vinyl acetate copolymer resin), etc.) are applied. Thereby, the tobacco rod continuum 500 which has a rod shape and has a long length is shape|molded (forming process, S102 in FIG. 6).

In addition, in the manufacturing method of the tobacco rod 2 in this embodiment, with respect to the some tobacco strand continuum 300 obtained in the cutting process (cutting section 1200), at least one of a fragrance|flavor and an aerosol generating base material. An addition step of adding may be further included. For example, the addition process may include wrapping a plurality of continuum of tobacco strands 300 with a wrapper (wrap web 400) in a forming process (forming section 1300), the plurality of continuum of tobacco strands 300. With respect to it, you may add at least one of a fragrance|flavor and an aerosol generating base material. Although the method of adding the fragrance or aerosol-generating substrate to the plurality of continuous tobacco strands 300 is not particularly limited, the tobacco strand continuum 300 may be added by discharging the fragrance or the aerosol-generating substrate from the addition nozzle. do. Of course, the addition nozzle for adding a fragrance|flavor and the addition nozzle for adding the aerosol generating base material may be provided separately. Moreover, although menthol etc. can be illustrated as a fragrance|flavor, you may add another fragrance|flavor. In the process of wrapping a plurality of continuum of tobacco strands 300 with a wrapper (wrap web 400) in the forming process (forming section 1300) as described above, a fragrance or aerosol generating substrate is added to the continuum of cigarettes 300.

The tobacco rod continuum 500 obtained in the forming section 1300 (forming process) is sent to a cutting section 1400 located at the rear end of the forming section 1300 . The cutting section 1400 has a cutting means such as a rotary cutter or a knife, and the long tobacco rod continuum 500 is cut to a predetermined length in the cutting section 1400 . That is, in the cutting step (S103 in Fig. 6), the tobacco rod continuum 500 obtained in the forming step (S102 in Fig. 6) is sequentially cut into individual tobacco rods, whereby the tobacco rods of the heated tobacco 1 are is obtained In addition, as is clear from the description up to the above, the plurality of tobacco strand continuums 300 cut from the tobacco raw material sheet 200 in the cutting section 1200 are cut in the axial direction in the cutting section 1400 until they are cut, It continues along the conveyance direction in the conveyance path P.

As mentioned above, according to the manufacturing method of the tobacco rod 2 in this embodiment, and the rod manufacturing apparatus 1000, the tobacco rod 2 concerning the heated tobacco 1 can be manufactured suitably. In particular, in the method for manufacturing the tobacco rod 2 and the rod manufacturing apparatus 1000 in the present embodiment, the tobacco raw material sheet 200 is continuously cut into a plurality of continuous tobacco strands 300 in the cutting section 1200 . Then, before cutting short the tobacco strand continuum 300 in the cutting section 1400, the tobacco strand continuum 300 aligned along the conveying path P is cut in the forming section 1300 from the wrapper (wrap web 400). )), and is characterized in that it is molded into a long tobacco rod continuum (500). By doing in this way, the some tobacco strands 23 can be aligned and arrange|positioned so that the some tobacco strands 23 may extend along the axial direction of the tobacco rod 2 . That is, it is possible to easily manufacture a tobacco rod 2 in which a plurality of tobacco strands 23 are arranged parallel to each other along the long axis direction of the tobacco rod 2 .

Moreover, in the rod manufacturing apparatus 1000, the tobacco strand 23 which has a desired thickness is obtained by adjusting the thickness of the tobacco raw material sheet 200 wound up of the 1st bobbin 1100. Further, by adjusting the spacing of each cutter disk 1220 in the slitter 1210 disposed in the cutting section 1200, the tobacco strand 23 having a desired width is obtained. In addition, in this embodiment, when cutting the tobacco raw material sheet 200 in the cutting section 1200 (cutting process), since it was made to cut into the some tobacco strand continuum 300 which has a fixed width, the tobacco rod 2 ), it is possible to make the cross-sectional area (width dimension) of each tobacco strand 23 uniform. Thereby, at the time of use of the heated cigarette 1, it becomes easy to suppress that the location where the delivery characteristic of an aerosol is non-uniform|heterogenous within the cross section of the tobacco rod 2 arises, and can supply an aerosol stably to a user.

Moreover, in the manufacturing method of the tobacco rod 2 in this embodiment, with respect to the tobacco raw material sheet 200 used for manufacture of the tobacco rod 2, calendering process beforehand, the said tobacco raw material sheet 200. The calendering process which raises the density of , and the winding-up process of winding up the tobacco raw material sheet 200 after this calendering process is performed to the 1st bobbin 1100 may be included.

FIG. 8 : is a figure explaining the calendering process with respect to the tobacco raw material sheet 200. As shown in FIG. A calendering process is performed by pressing the tobacco raw material sheet 200 by continuously passing the tobacco raw material sheet 200 between a pair of press rollers 600 and 600 as shown in FIG. 7, for example. By calendering the tobacco raw material sheet 200, the tobacco raw material sheet 200 becomes dense, and the density can be raised. As a result, while suppressing that the volume filling rate of the tobacco strand 23 contained in the tobacco rod 2 after manufacture becomes high excessively or the ventilation resistance of the tobacco rod 2 becomes high excessively, the weight of the tobacco strand 23 can increase As a result, the delivery amount of the aerosol in the tobacco rod 2 can be increased further.

Moreover, the tobacco raw material sheet 200 after performing a calendering process as mentioned above is wound up by the 1st bobbin 1100 in a winding process. The tobacco raw material sheet 200 wound up by the 1st bobbin 1100 is used for manufacture of the tobacco rod 2 by being taken out continuously along the conveyance path P as demonstrated with FIG. 5 and FIG. do.

In addition, as for the manufacturing method of the tobacco raw material sheet 200, an appropriate method, such as a paper making method (paper making method), a casting method (slurry method), a rolling method, or an extrusion method, as mentioned above, can be employ|adopted. have.

8 : is a figure explaining the method of manufacturing the tobacco raw material sheet 200 by the papermaking method (the sheet making method). As shown in FIG. 8, first, in step S201, the tobacco raw material containing a tobacco core, tobacco lamina, thin tobacco, tobacco powder, etc. is extracted with water (extraction). process). At an extraction process, a mixture is obtained by heating at predetermined temperature and time, adding and stirring the 10-fold quantity of water with respect to a tobacco raw material, for example. And in step S202, the mixture obtained in the extraction process is compressed using, for example, a screw press dehydrator, etc., and isolate|separates into aqueous tobacco extract (liquid) and insoluble tobacco residue (solid) (separation process). Next, in step S203, after adding water and pulp (cellulose fiber) to the insoluble tobacco residue obtained in the separation process, the insoluble tobacco residue is refined using a refiner, for example, and the fiber length is It is made into fibers by trimming or fluffing the fibers (the beating process).

Next, in step S204, the insoluble tobacco residue and pulp fiberized in the beating process are made into a sheet form with a paper machine, and a base sheet is obtained by making it dry (papermaking process). Next, in step S205, an additive liquid containing an aerosol-generating base material such as a concentrate of the aqueous tobacco extract obtained in the separation step and glycerin and propylene glycol is added to the base sheet (flavoring step). Further, in the flavoring step, the concentrate of the aqueous tobacco extract added to the base sheet is obtained, for example, by concentrating the aqueous tobacco extract with an evaporator. Next, in step S206, the flavored base sheet obtained in the flavoring process is dried (drying process).

According to the above manufacturing method, the tobacco raw material sheet 200 can be manufactured according to the papermaking method (papermaking method). However, the said manufacturing method is an example, and addition, omission, and substitution of a process can be performed suitably. In addition, in the tobacco raw material sheet 200 manufactured by the papermaking method (the sheet making method), the content of the aerosol generating base material is 15.0 wt%, the content of the tobacco raw material is 79.05 wt%, and the content of the pulp is 5.95 wt% Although the aspect made in % is given as an example, it goes without saying that it is not limited to this. In addition, in the tobacco raw material sheet 200 manufactured according to the paper making method (the sheet making method), it is preferable that the content of the aerosol generating base material is 10 wt% or more and 25 wt% or less.

9 : is a figure explaining the method of manufacturing the tobacco raw material sheet 200 by the casting method (slurry method). As shown in FIG. 9, first, in step S301, after pulverizing a tobacco raw material including tobacco core, tobacco lamina, lean tobacco, tobacco fines, and the like, a small amount of binder (binder) and a reinforcing agent ( A slurry (suspension) is obtained by mixing, for example, a dissolving fiber of the pulp, a predetermined amount of an aerosol-generating substrate (such as glycerin or propylene glycol) and water in a stirred tank. (Slurry Acquisition Process). As a binder (binder), guar gum, xanthan gum, CMC (methylol cellulose), etc. can be illustrated.

And next, in step S302, a slurry web is obtained by casting (stretching) the slurry obtained in the slurry acquisition process in sheet form on a steel belt (support body), for example (casting process). Next, in step S303, the sheet-like slurry web stretched into a sheet shape is dried (drying process). By the above process, the tobacco raw material sheet 200 is obtained. In addition, in the tobacco raw material sheet 200 produced by the cast method (slurry method), the content of the aerosol generating base material (eg, glycerin) is 15.0 wt%, the content of the tobacco raw material is 76.0 wt%, Although the aspect in which the content of the pulp is set to 6.0 wt% and the content of the binder is set to 3.0 wt% is given as an example, it is needless to say that the present invention is not limited thereto.

As mentioned above, although embodiment which concerns on this invention was described, the manufacturing method and manufacturing apparatus of the tobacco rod in the heated tobacco which concerns on this invention, a heated tobacco product, and a heated tobacco are not limited to these. For example, in the said FIG.1 and FIG.2, the aspect which makes the strand-shaped tobacco strand 23 arrange|positioned on the tobacco rod 2 into a straight-line shape which does not have a bending part is an example Although demonstrated, the tobacco strand 23 should just have an elongate elongate shape extended in a long-axis direction, and may employ|adopt another shape. 11 : is a figure which shows the tobacco strand 23A which concerns on a modification. The tobacco strand 23A shown in FIG. 11 has a serpentine shape (zigzag shape). The tobacco strands 23A extending in the serpentine shape in this way are arranged and arranged in the tobacco rod 2 so that their long axis direction (extension direction) extends along the long axis direction of the tobacco rod 2 . . When inserting the electric heater 103 in the heating device 100 into the tobacco rod 2, the tobacco strand 23A having such a serpentine shape (zigzag shape) is performed by the electric heater 103 of the cigarette. Even if the strand 23A is pushed, the positional difference of the tobacco strand 23A in the long-axis direction of the tobacco rod 2 can be made hard to occur. As a result, at the time of insertion of the electric heater 103 into the tobacco rod 2, the escape of 23 A of tobacco strands from the tobacco rod 2 can be suppressed appropriately.

In addition, the tobacco strand 23A shown in FIG. 11 is compared with the straight-line tobacco strand 23 shown in FIGS. 1 and 2, the aerosol produced|generated by the tobacco rod 2 by heating by the electric heater 103. Although it is said that the flow passage of It is difficult, and the delivery amount of an aerosol can be improved conventionally.

In addition, in the case of having a serpentine shape (zigzag shape) as shown in Fig. 11, the width of the tobacco strand 23A is from the front end face 23a to the rear end face 23b. It is desirable to be uniform throughout. That is, as shown in FIG. 11, it is preferable that the width dimension W1 of the site|part parallel to the long-axis direction of 23 A of tobacco strands and the width dimension W2 of the site|part extended in the direction orthogonal to the said long-axis direction are the same. do. By doing so, it is possible to make the cross-sectional area of the tobacco strand 23A uniform over the entire length. As a result, at the time of heating 23 A of tobacco strands by the electric heater 103, the difference in the generation amount of the aerosol in the long-axis direction of 23 A of tobacco strands can be suppressed appropriately. In addition, although 23 A of tobacco strands shown in FIG. 11 have a serpentine shape (zigzag shape), you may have a wavy shape and other shapes.
