<p>According to a method for the heating of dielectric materials, the heat generation is done by oscillating electromagnetic radiation of one or more frequencies withing the frequency range 300kHz-299 MHz, preferably within the frequency range 1 MHz-299 MHz and best of all within the frequency range 12 MHz-200 MHz. In an apparatus for the heating of dielectric materials, preferably of organic nature, the heat is generated by oscillating electromagnetic radiation within the frequency range 300 kHz-299 MHz. The apparatus comprises a chamber (10) consisting of an upper wall (12), a bottom wall (11) and side walls (13, 14, 15, 16) made of electric conducting materials, which walls together with at least one generator (19) are connected to a common reference potential at which the generator (19) is arranged to feed at least one with the chamber cooperating antenna (17) in order to get the electromagnetic radiation in this chamber.</p> |
