Abstract: A method of processing tobacco fines into a non-continuous tobacco material includes providing a pre-sized tobacco stem material that has a Dp90 particle size of less than 2.5 mm and a Dp50 particle size of between 0.7 mm and 1.5 mm, combining the pre-sized tobacco stem material with tobacco fines to provide a tobacco initial material, wherein the tobacco initial material includes between 40% and 60% pre-sized tobacco stem material (by mass). The method can include processing the initial material by setting the initial material to a predefined increased moisture content, subjecting the initial material to an increase in temperature and subjecting the initial material an increased pressure in order to bind the tobacco fines to the tobacco stem material, and conveying the initial material through a conveyor. The method can include feeding the processed tobacco material through a shearing gap such that the processed tobacco material is defibrated by expansion.

Abstract: A method of processing tobacco fines into a non-continuous tobacco material, the method including providing a pre-sized tobacco stem material that has a Dp90 particle size of less than 3 mm and a Dp50 particle size of less than 2 mm. The method also includes combining the pre-sized tobacco stem material with tobacco fines to provide a tobacco initial material, and processing the initial material by setting the initial material to a predefined increased moisture content, subjecting the initial material to an increase in temperature and subjecting the initial material an increased pressure in order to bind the tobacco fines to the tobacco stem material. There is also provided a non-continuous tobacco material produced by the method, a component for a delivery system including non-continuous tobacco material produced by the method, a product and a smoking article including the component.

Abstract: A method of treating tobacco material with superheated steam to reduce the nicotine content of the tobacco material after the treatment compared to the nicotine content of the tobacco material before the treatment. Also provided is treated tobacco material which has been contacted with superheated steam to reduce its nicotine content, as well as the use of superheated steam to treat tobacco and tobacco industry products that include the treated tobacco material.

Abstract: A method of treating tobacco material including combining pre-cut and/or pre-expanded stem with lamina to form an initial combination of stem and lamina; cutting the initial combination of stem and lamina; expanding the combination of stem and lamina; and intermittently contacting the expanded combination of stem and lamina with a heated surface to produce a treated tobacco material. An apparatus is also provided for treating tobacco material. Also provided is a treated tobacco material, as well as products including the same.

Abstract: Tobacco constituent releasing components comprising an agglomerated structure formed from a precursor composition comprising tobacco particles and one or more aerosol forming agents, processes for preparing tobacco constituent releasing components, and various tobacco industry products including the tobacco constituent releasing components.

Abstract: A method of treating cut stem tobacco material by expanding the cut stem to provide a first expanded tobacco material having a fill value at least about 10% greater than the fill value of the untreated cut stem tobacco material; intermittently contacting the first expanded tobacco material with a heated surface to provide a second expanded tobacco material with a moisture content of from 0 to about 10% OV and a fill value at least 5% greater than the fill value of the first expanded tobacco material; and (c) adjusting the moisture content of the second expanded tobacco material from about 5% to about 30% OV to provide an expanded product, wherein the fill value of the expanded product is at least 50% greater than the fill value of the untreated cut stem tobacco material when measured at a normalized moisture content of 14.5% OV.

Abstract: A process is provided for the treatment of tobacco. The process comprises securing the tobacco within a moisture-retaining material and exposing the tobacco material to an ambient processing temperature of above 55° C., with the tobacco having a packing density of at least 200 kg/m3 on a dry matter weight base at the start of the process and a moisture content of between about 10% and 23%. The treated tobacco may have desirable organoleptic properties.
