An apparatus for extruding dry powdered materials into stick form. The apparatus comprises a housing which contains a rotatable auger that conveys and extrudes the powdered material through an outlet orifice. The auger is composed of a pair of helical flight sections with the downstream flight section having a smaller pitch than the upstream flight section. The powdered material is fed to the upstream flight section through an inlet feed conduit and is extruded through the outlet orifice which is located adjacent the end of the downstream flight section and disposed generally transverse to the axis of the auger. The extruded powder rod is cut into short lengths which are conveyed to a collection area.
