MICROWAVE SYSTEM FOR HEATING VOLUMINOUS ELONGATED LOADS

摘要

Microwave heating system comprising an elongated cylindrical metal cavity intended for heating a voluminous elongated load. The system comprises microwave feeding means arranged to generate a single mode of the circular type TEm;n;p (a so-called whispering gallery mode) inside said 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.
