A method for increasing bulkiness of reconstituted tobacco by adding tobacco stem particles includes (1) pulverizing a first portion of tobacco stems to obtain tobacco stem particles; (2) classifying the tobacco stem particles with mesh sieves and selecting the tobacco stem particles with a predetermined mesh size; (3) extracting a second portion of the tobacco stems with water and grinding to form a tobacco stem slurry that has a beating degree of 12-14° SR, and mixing the tobacco stem slurry with tobacco leaves in a weight ratio of 6:4 and grinding to obtaining a tobacco slurry that has a beating degree of 18-20° SR; (4) cutting plant fiber pulp boards and dispersing in water to form a plant fiber pulp; (5) preparing a filler solution that contains 10 wt % of a mineral filler; (6) mixing, rolling and drying to obtain the reconstituted tobacco.

According to one embodiment, a method of producing a tobacco molded article, includes formulating a tobacco kneaded material by kneading a tobacco mixture containing a tobacco raw material, a binder and water, molding the tobacco kneaded material to obtain a molded body and adding a flavor to the molded body.

A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.

An article for use in a non-combustible aerosol provision system includes an aerosol-generating component circumscribed by a first wrapping material including a cellulose based material. The cellulose based material can have a basis weight greater than about 40 grams per square metre. There is also described a rod of aerosol-generating material having a length of less than 30 mm and wrapped in a first wrapping material and an outer wrapping material which extends at least partially over the rod of aerosol-generating material. There is also described a rod of aerosol-generating material wrapped in a first wrapping material and an outer wrapping material which extends over the rod of aerosol-generating material by a distance of between about 30% and 80% of the length of the rod of aerosol-generating material. A non-combustible aerosol provision system is also described.
