Abstract
An apparatus includes a microwave source emitting energy in a frequency range of about 300 Mhz to about 300 Ghz. At microwave cavity includes a stationary input section, a stationary output section, and a rotating processing section between the input section and the sample output section. A waveguide introduces microwave energy into at least one of the sample input section and the sample output section.
Claims33
An apparatus, comprising:
- a microwave source, wherein the source emits microwave energy in a frequency range of about 300 Mhz to about 300 Ghz;
- at least one microwave cavity comprising a stationary input section, a stationary output section, and a rotating processing section between the input section and the output section;
- and
- a waveguide to transmit the microwave energy from the source and introduce the microwave energy into at least one of the input section and the output section.
1 more element
A method, comprising:
- continuously introducing a sample material into a processing section of a microwave cavity;
- wherein the processing section comprises a secondary coupler;
- introducing microwave energy into the cavity, wherein the secondary coupler absorbs the microwave energy and heats the sample material to a target temperature;
- rotating the processing section;
- and
- continuously removing the processed sample material from the processing section.
