Abstract

The substance is passed through a tube of a material permeable by microwaves, positioned in a field of microwaves. The equipment for the heating process includes a tube of a material permeable to microwaves, and means of feeding the substance into the tube together with mechanical means of progressing the substance through the tube. There is a resonating chamber inside which the tube is located and there are means of producing microwaves inside the resonating chamber. Used for the application of heat under fully controlled circumstances to a particular substance in granule or particle of powder form, in motion.
