Process for the Extrusion of Wood Pellets, Co-Ratating Twin-Screw Extruder for the Extrusion of Wood Pellets, and Corresponding Wood Pellets

Abstract

The invention relates to a method for extruding wood pellets, the method being characterized in that it comprises at least the steps of: (a) providing pieces of wood; (b) grinding and partially drying, in a twin-screw extruder including at least shear generating elements, pieces of wood to obtain wood particles having a reduced water content compared to the pieces of wood; (c) compressing the particles and shaping in at least one die to obtain wood pellets. The invention also relates to a wood pellet capable obtained with this method and a co-rotating twin-screw extruder intended for the extrusion of wood pellets
