Publication number: 20230371573Abstract: 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.Type: ApplicationFiled: September 14, 2021Publication date: November 23, 2023Inventors: Matthias LINK, Dietmar FRANKE, Frank PLÜCKHAHN
