Abstract
A method and a device for pressing a liquid extract from a material to be pressed include a screw press which conveys the material to be pressed along a pressing route and applies pressure to it. In addition, at least one extracting agent is added to the material to be pressed and is removed, together with the extract, from the pressed material. The extracting agent is supplied to the material to be pressed in an amount that is no more than twice the weight of the extract contained in the material to be pressed. At least a portion of the extracting agent dissolves in the extract.
