Mobile metallic temperature sensor as t iste ain c te temperature sensor was placed in parallel to the electric field component within microwave cavities h inte rnatin continuously through these four sections by a microwave transpar-ent conveyor belt. Microwave heating section is the key part which can elevate the temperature of a food product by more than 50 C (e.g., from 70 C to 121 C) in three minutes. This section has four connected single-mode microwave heating cavities each with a minor different internal configuration to provide complementary files are directly locations cation tha led the col In microwave heating, the temperature distributions at d locations are caused by uneven electric field distributions than one cold spots may exist in a microwave heated food product. Likewise, hot spots may also be present at different positions in microwave heated foods. Unlike multi-mode microwave heating systems in which heating patterns are difficult to predict due to the co-existence of several resonant modes within the frequency bandwidth that coincides with the power spectrum of industrial microwave generators (Chan and Reader, 2000), the single mode MATS system can provide a stable and predictable heating patter
