Abstract
A screw conveyor for transporting lignocellulose-containing material, including a housing containing a screw for transporting the lignocellulose-containing material from the inlet to the outlet of the housing, the screw including a screw core disposed along the screw axis and a screw thread surrounding the screw core, the screw thread including a screw depth defined by the distance between the periphery of the screw and the screw core, the inlet including at least one transverse plate dividing the inlet into at least two axial compartments for evenly distributing the lignocellulose-containing material at the inlet. A method for transporting lignocellulose-containing material by the screw conveyor, in which the axial length of the screw inlet being equal to or greater than the screw depth times the quotient between the axial speed of the screw and the incoming speed of the lignocellulose-containing material at the inlet.
