ABSTRACT OF THE DISCLOSURE A method of feeding fibrous ligno-cellulose raw material into a pressurized vessel such as a digester operating at approximately 300 pounds per square inch. The raw material is first pre-compacted by a screw conveyor and subsequently compacted to a density of at least 45 pounds per cubic foot of oven dry material to form a plug in a feeding conduit communicating with the digester. During the pre- compacting and compacting stage, the moisture of the material is maintained at a natural level of about 10% to 50% by weight. The plug thus forms a continuously advancing mass of material which-separates the interior of the digester from the surrounding atmosphere without the need of special valve means normally used in prior art. The advancement of the plug takes place along a straight line generally coincident with the centreline of the screw conveyor but axially spaced from same.
