Abstract: There is provided a heated aerosol-generating article for producing an inhalable aerosol, the heated aerosol-generating article including: an aerosol-forming substrate that is a homogenized tobacco material including tobacco, a fat having a melting point between 20° C. and 50° C., and one or more aerosol-formers, the homogenized tobacco material containing at least 60% tobacco on a dry weight basis. A homogenized tobacco material is also provided.

Abstract: A method of forming homogenized tobacco material is provided, including forming a homogenized slurry including tobacco powder; casting the homogenized slurry onto a moving belt; incorporating a porous reinforcement sheet into the cast homogenized slurry; and drying the cast homogenized slurry with the incorporated porous reinforcement sheet to form the homogenized tobacco material, the porous reinforcement sheet having anisotropic properties such that the porous reinforcement sheet has a higher tensile strength in a longitudinal direction thereof than in a transverse direction thereof.

Abstract: There is provided a method of making rods having predetermined values of cross-sectional porosity, and a cross-sectional porosity distribution value for use as an aerosol-forming substrate in a heated aerosol-generating article, including providing a continuous sheet of aerosol-forming material having a specified width and a specified thickness; gathering the sheet transversely relative to a longitudinal axis thereof; circumscribing the gathered sheet with a wrapper to form a continuous rod; severing the rod into a plurality of discrete rods; determining values of cross-sectional porosity and cross-sectional porosity distribution for at least one of the discrete rods; and controlling one or more manufacturing parameters to ensure that the cross-sectional porosity and cross-sectional porosity distribution values of subsequent rods are within the predetermined values.

Abstract: The invention relates to a method for the preparation of a homogenized tobacco material, said method comprising: —pulping and refining cellulose fibres to obtain fibres having a mean size comprised between about 0.2 millimetres and about 4 millimetres; —grinding a blend of tobacco of one or more tobacco types to a tobacco powder having a mean size comprised between about 0.03 millimetres and about 0.12 millimetres; —combining the pulp with the tobacco powder blend of different tobacco types and with a binder in an amount comprised between about 1 percent and about 5 percent in dry weight basis of the total weight of the homogenized tobacco material, so as to form a slurry; —homogenizing the slurry; and—forming the homogenized tobacco material from the slurry.

Abstract: The present invention relates to a method of preparation of a slurry for the production of a homogenized tobacco material, said method comprising: —suspending a binder in an aerosol-former to form a suspension; —creating a cellulose pulp from cellulose fibers and water; —providing a tobacco powder blend; and —combining said suspension of binder in aerosol-former, said cellulose pulp and said tobacco powder blend to form said slurry.

Abstract: An aerosol-generating article is provided, including a plurality of elements assembled in the form of a rod, the plurality of elements including an aerosol-forming substrate, and a mouthpiece filter located downstream from the aerosol-forming substrate within the rod. The aerosol-generating article further includes a volatile flavor-generating component disposed between the aerosol-forming substrate and the mouthpiece filter within the rod. In some embodiments, the volatile flavor-generating component is supported by a low resistance support element located between the aerosol-forming substrate and the mouthpiece filter. In some embodiments, the volatile flavor-generating component is menthol.
