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.

Method for the continuous drying of wet, granular and/or lumpy materials

The invention relates to a method for separation of liquids from a mixture of solid matter and liquids by supplying said mixture to a separation member which is permeable by liquid, simultaneously applying a vacuum to the underside of said separation member, and subjecting said separation member to vibrations. The invention also includes a device for carrying out said method.
