High frequency dielectric heating system

摘要

A method and apparatus for dielectric drying is disclosed wherein a load to be heated positioned on a carrier the bottom of which provides a secondary electrode is moved with the carrier a dielectric heating chamber having a primary electrode positioned above load when said load on said carrier is moved into an operative position in the chamber. The carrier and load are elevated into heating position and this movement simultaneously connects the secondary electrode to ground, so that when high frequency power is applied to the primary electrode the circuit is made to dielectrically heat the load.
