Description

Flavor molding for non-combustion heating flavor inhaler, method for producing the same, and non-combustion heating flavor inhaler

The present invention relates to a flavor molding for a non-combustion heating flavor inhaler, a method for producing the same, and a non-combustion heating flavor inhaler.

A combustion-type flavor inhaler (cigarette) obtains flavor by burning a tobacco filling containing leaf tobacco. As an alternative to the combustion type flavor inhaler, a non-combustion heating type flavor inhaler has been proposed in which flavor is obtained by heating a flavor source including tobacco material instead of burning it. The heating temperature of the non-combustion-heating flavor inhaler is lower than the combustion temperature of the combustion-type flavor inhaler, for example, about 400° C. or less. Thus, since the heating temperature of the non-combustion heating type flavor inhaler is low, an aerosol generating agent such as glycerin is added to the flavor source in the non-combustion heating type flavor inhaler from the viewpoint of increasing the amount of smoke. The aerosol-generating agent is vaporized by heating to generate an aerosol. Since the aerosol is supplied to the user together with flavor components such as tobacco components, the user can obtain sufficient flavor. For example, Patent Literature 1 discloses a flavor source for a combustion type flavor inhaler. Further, Patent Literature 2 discloses a flavor source for a non-combustion heating type flavor inhaler.

Here, the compression breaking strength of the flavor molded body with a pile-shaped plunger measured using a tablet hardness tester is 10 N or more.

The flavor molding according to the present embodiment has a shape of a certain size as a molding, so stickiness is suppressed, and since it has high strength, it is easy to handle as it is, and it is not necessary to fill a pot or wrapping paper. . In addition, since the flavor molding according to the present embodiment forms a carbonized layer on the surface to be heated to improve breaking strength, the strength is high even after use (after heating). Therefore, the shape of the molded body can be sufficiently maintained even after use, and post-processing is easy. Furthermore, in the flavor molded product according to the present embodiment, since the volatile flavor components are adsorbed by an adsorbent such as activated carbon, the volatile flavor components are gradually released from the adsorbent by heating, and the flavor components are stabilized throughout use. and volatilize. In addition, since the amount of water in the molded body can be suppressed by being adsorbed by the adsorbent, it is easy to mold during molding.

(Tobacco powder raw material)
Tobacco powder raw materials include, for example, leaf tobacco, leaf veins, stems, roots, flowers, etc. of tobacco which have been chopped into powder. The type of leaf tobacco is not particularly limited, and may be, for example, yellow variety, burley variety, native variety, oriental leaf, fermented leaves thereof, or the like. These tobacco powder raw materials may be used alone or in combination of two or more.

Although the average particle size of the tobacco powder raw material is not particularly limited, it is preferably 100 μm or less. When the average particle size is 100 μm or less, a molded flavor product having higher strength can be obtained. The average particle size is preferably 5 to 80 μm, more preferably 10 to 60 μm, even more preferably 20 to 50 μm. The average particle size is measured using a light scattering method.

(volatile perfume ingredients, adsorbents)

One of these volatile perfume components may be used, or two or more thereof may be used in combination.

The volatile fragrance component is adsorbed by the adsorbent. That is, the volatile perfume ingredients are retained in the adsorbent, and can be adsorbed and retained, for example, within the pores of the adsorbent. Examples of adsorbents include activated carbon, silica gel, ion exchange resins, molecular sieves and zeolites. One kind of these adsorbents may be used, or two or more kinds thereof may be used in combination. Among these, as the adsorbent, the volatile flavor component can be sufficiently retained, and as described later, the non-combustion heating type flavor inhaler is a microwave heating type flavor inhaler or an induction heating type flavor inhaler. In some cases, activated carbon is preferred from the viewpoint that it can generate heat during heating and increase the volatilization amount of the perfume component in the initial stage of use.

By containing two or more adsorbent particles in the flavor molded body, the adsorbent particles are dispersed in the flavor molded body, and the volatilization amount of the flavor component in each puff is further stabilized. Although the average particle size of the adsorbent particles is not particularly limited, it can be, for example, 0.3 to 2.0 mm. The average particle size is measured using a dry sieving method.

Also, in the present embodiment, it is preferable that the adsorbent is not exposed on the surface of the molded flavor product. Since the adsorbent is not exposed on the surface of the flavor molded body, the appearance is improved, and when the flavor molded body is molded, the adsorbent such as activated carbon does not adhere to the molding machine, thereby improving production efficiency. For example, by covering the surface of a flavor molded body containing an adsorbent with components of a flavor molded body that does not contain an adsorbent, it is possible to obtain a flavor molded body in which the adsorbent is not exposed on the surface. It can be visually confirmed that the adsorbent is not exposed on the surface of the molded flavor product.

In addition, it is presumed that the addition of ethanol dehydrates some hydroxyl groups of the cellulose contained in the tobacco powder raw material and condenses them with nearby cellulose, resulting in the formation of a flavor molding having high strength. Thus, in the method according to the present embodiment, it is not necessary to use a general binding agent (binder) during molding, and most of the ethanol used is removed, so the flavor is not affected, and A flavor molding having high strength can be obtained.

Each step in the method according to the present embodiment will be described below, but the method according to the present embodiment may include steps other than the raw material mixing step, compression molding step, and ethanol removal step. Further, the ethanol removal step may be performed during the compression molding step or after the compression molding step, as long as it is after the raw material mixing step.

(Raw material mixing process)
In this step, a tobacco powder raw material, an adsorbent that adsorbs volatile flavor components, ethanol, and an aerosol source are mixed to form a mixture. As for the amount of ethanol to be mixed, it is preferable to mix 1 to 20 parts by mass of ethanol with 100 parts by mass of the tobacco powder raw material. By mixing 1 part by mass or more of ethanol with 100 parts by mass of tobacco powder raw material, a flavor molding having higher strength can be obtained. Compression molding can be easily performed by mixing 20 parts by mass or less of ethanol with 100 parts by mass of the tobacco powder raw material. In this step, it is more preferable to mix 3 to 17 parts by mass, more preferably 5 to 15 parts by mass, of ethanol with 100 parts by mass of the tobacco powder raw material.

In this step, other ingredients such as cellulose powder, tea powder, Labiatae plant powder, Umbelliferae plant powder, etc. are added in addition to the tobacco powder raw material, the adsorbent that adsorbs the volatile flavor component, ethanol and the aerosol source. Further mixing is possible. In particular, cellulose powder can further improve the strength of the molded flavor product. Although the method of mixing the raw materials is not particularly limited, they can be mixed using a general mixer such as a V-type mixer.

(Compression molding process)
In this step, the mixture obtained in the raw material mixing step is compression-molded. A compression molding machine used for compression molding is not particularly limited, and examples thereof include a rotary tableting machine. The conditions for compression molding are not particularly limited, but molding is preferably performed at a compression pressure of 2 kN or more, for example. As described above, at least part of the ethanol may be removed by natural drying or the like during compression molding.

(Ethanol removal step)
In this step, at least part of the ethanol is removed from the mixture. Here, as described above, at least part of the ethanol may be removed from the mixture during the compression molding step, or may be removed from the molded body obtained after the compression molding step. may

In this step, it is preferable to remove at least part of the ethanol at 10-40°C. Ethanol can be sufficiently removed by removing at least part of the ethanol at 10° C. or higher. In addition, by removing at least part of the ethanol at 40° C. or less, it is possible to suppress the influence of heating on the flavor. The temperature at which at least part of the ethanol is removed is more preferably 15 to 35°C, still more preferably 20 to 30°C. When at least part of the ethanol is removed at 10-40° C., for example, at least part of the ethanol can be removed by drying at 10-40° C. for 30-180 minutes. At least part of ethanol can be removed by, for example, an electric oven, hot air drying, tunnel dryer, air drying, or the like. In addition, it is preferable to remove ethanol in an open space rather than in a closed space.

By this step, 90% by mass or more of ethanol contained in the mixture (molded body) is preferably removed, more preferably 95% by mass or more is removed, and 99% by mass or more is removed. More preferably, it is especially preferred that all ethanol is removed.
