1. A machine for providing thermic drying treatment of a dielectric product comprising:
box-like casing which defines a process chamber or cavity suitable for receiving a dielectric product placed on a supporting system and to be thermally treated to obtain drying of the dielectric product;
a vacuum pump operatively connected with said box-like casing and suitable to be operated to create vacuum conditions inside said process chamber or cavity in a presence of said dielectric product;
an electric generator for generating a radio frequency output signal, at a desired output power;
an applicator, contained in said process chamber or cavity and electrically connected with said electric generator, suitable to develop an electromagnetic field at a treatment zone of said dielectric product defined in said process chamber or cavity for heating said dielectric product;
wherein the applicator includes a pair of polarity opposed electrodes facing each other, arranged one with respect to an opposing other, according to a predetermined configuration; and
each of said pair of electrodes include a plurality of consecutively arranged electrodes, each of the plurality of consecutively arranged electrodes having a same polarity or an opposite polarity with respect to an adjacent one of the plurality of consecutively arranged electrodes.
