20100139674 | Tobacco Shredder With Double-Mounted Conveyor-Worm Shaft - The invention relates to a tobacco shredding device with a heatable pressure chamber ( | 06-10-2010 |
20100139675 | High-pressure forming process for tobacco material - The invention relates to a method of producing cut tobacco material, whereby a tobacco starting material is heated and brought to a first increased pressure in one method stage; whereby the tobacco material is pumped to a second increased pressure in the second method stage which is higher than the first increased pressure; and whereby the tobacco material, heated and placed under pressure, is expanded and fed through a forming tool ( | 06-10-2010 |
20110088705 | Defibration of Tobacco Material - The invention relates to a method of producing cut tobacco material, whereby a tobacco initial material is heated and placed under pressure and once heated and placed under pressure, the material is fed through a shearing gap and expanded and defibrated. It further relates to a device for producing cut tobacco material with a pressure chamber, which has a tobacco material inlet at the low-pressure end and a tobacco material outlet at the pressure end and a conveyor system for conveying the tobacco material from the inlet to the outlet, and the tobacco material outlet has a gap through which the material passes and expands, and the gap has walls which can be moved towards one another. It further relates to a smoking article containing such a cut, defibrated tobacco material product and the use of a plug screw feeder-extruder with a shearing gap outlet for defibrating tobacco material. | 04-21-2011 |
20110283556 | Production of smoking products by thermal extrusion - The invention relates to a method for producing a smoking product from a tobacco material, wherein the tobacco material is treated using at least one extrusion process, which comprises compaction with an increase in pressure and temperature and a mechanical treatment and sudden flash drying of the material at an outlet of an extruder ( | 11-24-2011 |
20110284015 | Modular tobacco preparation including extrusion - The invention relates to a tobacco preparation method, wherein a tobacco material is prepared through at least one extrusion process comprising compressing the material with an increase in pressure and temperature and mechanically processing and abruptly flash drying the material of an extruder outlet, wherein the tobacco material comprises a tobacco lamina material. The invention further relates to a tobacco preparation device comprising a dosing conveyor ( | 11-24-2011 |
20110309559 | Shaping and dimensioning of plant material containing cellulose - The invention relates to a method for shaping and dimensioning plant material containing cellulose, according to which the plant material is prepared by at least one extrusion process involving a compression by means of a pressure and temperature increase as well as mechanical processing of the material at an outlet of an extruder ( | 12-22-2011 |
20120006341 | Extractive Tobacco Material Extrusion - The invention relates to a method for extracting agents from a tobacco material, wherein the tobacco material is conveyed through a housing to which an extraction agent ( | 01-12-2012 |
20150136151 | Extractive Tobacco Material Extrusion - The invention relates to a method for extracting agents from a tobacco material, wherein the tobacco material is conveyed through a housing to which an extraction agent is fed and from which the extraction agent is again discharge, wherein the extraction occurs in an extruder under increased extrusion pressure by way of contacting the tobacco material with the extraction agent during a tobacco material extrusion process. The invention further relates to an extraction device for tobacco material, having a housing and a conveyor unit in the housing, and having an extraction agent inlet and an extract outlet, wherein the housing is associated with a screw extruder, wherein the extract is separated from the extruder to the outside environment by means of the pressure generated therein across the drop of pressure. | 05-21-2015 |
