Abstract

See full text

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 (14, 24) is fed and from which the extraction agent is again discharged, wherein the extraction occurs in an extruder (10, 20) 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 (13, 23) and a conveyor unit (5) in the housing, and having an extraction agent inlet (3) and an extract outlet (7), wherein the housing is associated with a screw extruder (10, 20), wherein the extract is separated from the extruder (10, 20) to the outside environment by means of the pressure generated therein across the drop of pressure.
