Abstract:
1. An apparatus for heating and dispensing particulate material, comprising: a housing having an outlet portion having an axis and a central orifice on the axis; an outer susceptor mounted within the housing in coaxial alignment with the orifice, the outer susceptor having a perforated side wall, the side wall of the outer susceptor and the housing defining between them an annular outer bin having an inlet for receiving a portion of the particulate material prior to melting; an inner susceptor mounted within the outer susceptor in coaxial alignment with the orifice and being non rotatable relative to the outer susceptor, the inner susceptor having a perforated side wall, the side wall of the inner susceptor and the side wall of the outer susceptor defining between them an annular heating chamber that is open to the orifice, the side wall of the inner susceptor defining an inner bin having an inlet for receiving a portion of the particulate material prior to melting; an induction coil disposed within the heating chamber to cause the inner and outer susceptors to apply heat to the particulate material in the inner and outer bins and to cause the particulate material to melt and flow through perforations of the inner and outer susceptors into the heating chamber and from the heating chamber into the outlet portion and out the orifice; and wherein the outer bin and the inner bin having ends opposite the inlets that are closed so as to prevent the particulate material within the outer and inner bins from flowing directly to the orifice rather than through the perforations.
