ABSTRACT:
A method for metering powdered or granular material onto a heated surface to vaporize such material. The method comprises providing a rotatable auger d for receiving powdered or granular material and as the rotatable auger rotates, such rotatable auger translates such powdered or granular material along a feed path to a feeding location. The method also providing at least one opening at the feeding location such that the pressure produced by the rotating rotatable auger at the feeding location causes the powdered or granular material to be forced through the opening onto the heated surface in a controllable manner. The material is agitated or fluidized proximate to the feeding location.
