Microwave system for heating voluminous elongated loads

摘要

A Microwave heating system includes an elongated cylindrical metal cavity intended for heating a voluminous elongated load. The system includes microwave feeding means arranged to generate a single mode of the circular type TEm;n;p (a so-called whispering gallery mode) inside the cavity in order to heat the elongated load, wherein the circumferential index m is at least 4, the radial index n=1 and the axial index p being >0. The heating system is preferably adapted for wood processing.
