Abstract
A method and apparatus for drying wet granular and/or lumpy materials, employs a chamber having a material inlet, a material discharge outlet, an inlet for a heated drying fluid and a vapor outlet. A perforate sieve-type material support extends along a path between the material inlet and the material discharge outlet to provide communication between the drying fluid and vapor outlet through the material and a microwave generating and transmitting device is located above the material path to irradiate the material with microwave energy as a part of the drying energy supplied to the material.
