A combined machine for the thermic drying treatment of dielectric products includes a box-like casing which defines a process chamber or cavity configured to receive a dielectric product placed on support means and to be thermally treated to obtain the drying thereof. A pumping means is operatively connected to the box-like casing and configured to be operated to create vacuum conditions inside the process chamber or cavity in the presence of the dielectric product. In particular, the combined machine includes an electric generator configured to generate a radio frequency output signal, at the desired output power, and applicator means, contained in the process chamber or cavity and electrically connected with the electric generator, configured to develop an electromagnetic field at a treatment zone of the dielectric product defined in the process chamber or cavity for heating the dielectric product itself.
