Abstract: A method for drying granulated dielectric materials including superhigh frequency heating of granules which are moved in heating space by a strong hot air flow. The granules are moved at a variable speed, a negative temperature gradient is produced, and humid air is removed from the heating space. According to the invention, the apparatus for drying granulated dielectric materials includes a superhigh frequency generator and a drying chamber which, in turn, has an input waveguide and an output waveguide interconnected by a waveguide elbow. An air inlet and a granules inlet are connected to an input of the input waveguide. The output waveguide has an air separator arranged at its input and a resonator bin arranged at its output.
