Problems solved by technology

While good results are possible with such systems, the use of conventional electrodes may make the electromagnetic field in the compartment non-uniform, which may lead to uneven thawing of the load and / or hot spots that may inappropriately cook portions of the load

Abstract

A heat augmentation system includes one or more multi-level electrodes configured to radiate electromagnetic energy into the cavity in response to receiving an RF signal from a radio frequency (RF) signal source. Each multi-level electrode is positioned adjacent to the wall of the cavity, and each multi-level electrode includes a base portion coupled to the elevated portion. The radiation surfaceof the elevated portion is at a height of at least 0.5 centimeters (cm) from the radiation surface of the base portion.

Description

technical field [0001] Embodiments of the subject matter described herein relate generally to apparatus and methods for heating and / or thawing loads using radio frequency (RF) energy. Background technique [0002] Conventional capacitive food defrosting systems include large planar electrodes contained within a heating compartment. After placing the food load between the electrodes, low power electromagnetic energy is supplied to the electrodes to generate an electromagnetic field in the heating compartment which gently heats the food load. While good results are possible with such systems, using conventional electrodes can make the electromagnetic field in the compartment non-uniform, which can lead to uneven thawing of the load and / or hot spots that can improperly cook portions of the load. Contents of the invention [0003] According to a first aspect of the present invention there is provided a heat augmentation system coupled to a cavity for containing a load, the he...
