Abstract
A radio frequency (RF) heating system and process for rapidly and uniformly heating a plurality of articles on a convey line.
Claims25
A radio frequency (RF) heating system for heating a plurality of articles, said RF heating system comprising:
- an RF generator for generating RF energy;
- an RF waveguide configured to be substantially filled with a waveguide liquid and, when filled with said waveguide liquid, capable of transmitting at least a portion of said RF energy produced by said RF generator;
- an RF heating chamber configured to be substantially filled with a heating chamber liquid and, when filled with said heating chamber liquid, capable of receiving at least a portion of said RF energy transmitted through said RF waveguide;
- and
- a convey system received in said RF heating chamber and configured to convey said articles through said RF heating chamber while said articles are being heated by at least a portion of said RF energy.

A process for heating a plurality of articles using radio frequency (RF) energy, said process comprising:
- (a) passing RF energy through at least one RF waveguide substantially filled with a waveguide liquid;
- (b) introducing at least a portion of said RF energy into an RF heating chamber substantially filled with a heating chamber liquid;
- and
- (c) heating articles conveyed through said RF heating chamber using at least a portion of said RF energy.
