Tobacco cut filler has an extremely high filling capacity. Tobacco cut filler is contacted with tap water under extraction conditions, and resulting aqueous tobacco extract is separated from the water insoluble extracted tobacco material. The extracted tobacco material is contacted with humectant, provided at a desired moisture level, and subjected to volume expansion conditions. Volume expanded extracted tobacco materials are used as smokable materials in cigarette manufacture.

Process for increasing the filling power of tobacco material

Denicotinized tobacco cut filler is provided by (i) extracting the cut filler with an aqueous denicotinized extract and thereby providing a mixture of aqueous extract and extracted cut filler, (ii) deliquoring the mixture of aqueous extract and extracted cut filler such that a certain level of tobacco extract remains in contact with the extracted cut filler, and (iii) drying the deliquored tobacco extract/extracted cut filler to provide a processed cut filler. Greater than 90 percent of the nicotine present in tobacco cut filler can be removed therefrom using such process steps.

Tobacco processing

A process and apparatus for producing plastic-bound propellant powders and explosives in crystalline form, with the apparatus including an extruder comprising a casing with a feed opening, optionally a solvent supply opening and one or two extruder shafts with kneading and conveying segments. For processing the plastic binders, which polymerize photochemically or under X-rays, a casing section transparent for the rays is provided, with polymerization within the extruder being initiated by UV/VIS or X-radiation sources arranged around it and the radiation intensity and/or the wavelength of the radiation are controlled as a function of the pressure difference over a given path in a compression zone of the extruder, in such a manner that the propellant or explosive strand or strands leave the extruder in a dimensionally stable and cuttable manner.
