Fremgangsmåde til bearbejdning af finskåren tobak til et ikke-kontinuerligt tobaksmateriale

There is provided a method of processing tobacco fines into a non-continuous tobacco material. The method 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 0.7mm and 1.5mm, combining the pre-sized tobacco stem material with tobacco fines to provide a tobacco initial material, wherein the tobacco initial material comprises between 40% and 60% pre-sized tobacco stem material (by mass). The method can also 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, wherein the conveyer is operated at a throughput of greater than 100 kg/hr. The method can also include feeding the processed tobacco material through a shearing gap such that the processed tobacco material is defibrated by expansion, wherein the shearing gap is arranged between shearing surfaces, wherein a rotatable shearing member comprises one of the shearing surfaces, wherein the shearing member comprises at least 140 grooves and wherein the grooves each have a maximum width in the circumferential direction of the shearing member of between 0.7mm and 1mm. 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 comprising the component.
