Smoking article

A smoking article, such as a cigarette, comprises a lighting end and a mouth end. The smoking article possesses an aerosol-generation system that includes (i) a heat generation segment, and (ii) an aerosol-generating region or segment. A mouth end piece segment can be located at the mouth end of the smoking article. A segment of tobacco cut filler, gathered tobacco paper, or other type of flavor source material, can be positioned between the mouth end piece segment and the aerosol-generation segment. Optionally, segment composed of tobacco cut filler can be positioned so as to provide a lighting end segment. The smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the mouth end piece segment, the aerosol generation segment, at least a portion of the length of the heat generation segment, any segment located between the mouth end piece and aerosol generation segments, and at least a portion of the length of the optional lighting end segment. Alternatively, the smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the aerosol-generating segment, at least a portion of the length of the heat generation segment, at least a portion of any segment located downstream from the aerosol-generating segment, and at least a portion of the length of the optional lighting end segment, thereby forming a cigarette rod; and the cigarette rod is connected or attached to a filter element using a tipping type of material and arrangement.

Smokable rod for a cigarette

InactiveUS20050066986A1Not easily dislodgedNot overly flakeyTobacco preparationCigar manufactureEngineeringTobacco smoke
A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with an optional burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and an optional burn suppressing agent. Alternatively, a smokable rod possesses a single blend of smokable materials; at least a portion the smokable material being a tobacco material carrying a relatively high amount of aerosol forming material; and optionally at least a portion of the smokable material being in intimate contact with a burn suppressing agent. A filtered cigarette can be produced by attaching a filter element to one end of any of those smokable rods.

Reconstructed tobacco coating liquid component-component group chemical kitchen combination, coupling preparation, and coupling preparation process

The invention relates to a reconstructed tobacco coating liquid component-component group chemical kitchen combination, coupling preparation, and a coupling preparation process. Discarded waste tobacco leaves and stems are subjected to presoaking and enzymatic leaching or extraction to make tobacco leaf or stem enzymatically-leached/extracted solution, or tobacco leaf and stem mixed leached/extracted solution, certain components and component groups such as protein, pectin, chloride, nicotine, nitrosamines, nitrates and the like in the tobacco leaf and stem leached/extracted solution or tobacco leaf and stem leached/extracted mixture can be selectively converted, reduced or removed by combination of enzymolysis, Maillard reaction conversion, membrane separation/concentration or column separation, freeze separation, ethanol precipitation and the like, and the coupling preparation process for chemical components and component groups in the chemical kitchen, and accordingly, recombination or fitting, combination, regulation and coke reduction and harm reduction of the chemical components and component groups of the reconstructed tobacco coating liquid are achieved, quality of reconstructed tobacco is improved, and industrial technical integration and innovation on combination and coupling of the reconstructed tobacco coating liquid are realized.

Bagging oral containing tobacco and manufacture method thereof

The invention relates to a tobacco, in particular to a bagged lip tobacco, and is characterized in that the bagged lip tobacco comprises package and moist tobacco powder particles in the package; wherein, the tobacco powder particles are mainly composed of the ingredients by weight ratio as follows: tobacco ingredient is 10 percent to 70 percent, water is 10 percent to 60 percent, acid-base modifying agent is 0.01 percent to 2 percent, correctives are 1 percent to 20 percent, and humectants are 1 percent to 10 percent. The preparation method sequentially comprises the steps as follows: tobacco ingredient is crushed and screened to obtain coarse tobacco powders with different particle sizes; the coarse tobacco powders are added with water for mixing, and fumigated by using vapor, added with the correctives, cooled, added with different modifying agents, humectants, and flavoring agents, and packed, so that the tobacco is obtained. The bagged lip tobacco has the advantages that the use is convenient; no crumbs fall on a mouth when in use; no smoke is sent out to harm others at the same time; the bagged lip tobacco makes up for the disadvantages of the existing chewing tobacco lip tobacco, and provides the contented sensation similar to the traditional cigarettes and chewing tobacco products to tobacco consumers.

Intensive curing barn precise curing process for flue-cured tobacco

The invention discloses an intensive curing barn precise curing process for flue-cured tobacco. The process mainly comprises three curing stages, namely a yellowing stage, a color fixing stage and a stem drying stage, wherein three key temperature and humidity points are controlled in the yellowing stage; four key temperature and humidity points are controlled in the color fixing stage; one key temperature and humidity point is controlled in the stem drying stage; a flue-cured tobacco temperature and humidity automatic control system is adopted in an entire curing process; and a temperature sensor and a humidity sensor are arranged on the top layer of a down-draft intensive curing barn or the bottom layer of an up-draft bulk curing barn. Through the process, error and loss of manual operation brought by operation by experience are reduced, curing quality of tobacco leaves is improved, curing cost is reduced, and high operability is guaranteed. As proved, badly cured tobacco such as green and miscellaneous tobacco and the like is obviously reduced, proportion of orange tobacco and first-class tobacco is increased, the cured tobacco has a loose structure and increased oil content, and appearance quality inside and outside the tobacco leaves and availability are obviously improved.
