1. A food processing machine for processing a food product, the food processing machine comprising:
a one or more walls defining a chamber;
a conveyor configured to convey the food product through the chamber;
a convection heating system configured to heat the food product as the food product is conveyed through the chamber;
a microwave launch box system configured to emit microwave energy into the chamber and thereby further heat the food product as the food product is conveyed through the chamber;
a microwave monitoring detector for detecting microwave energy leaking from the food processing machine; and
a controller in communication with the microwave monitoring detector, the controller being configured to shut off a part of the microwave launch box system when microwave energy detected by the microwave monitoring detector is equal to or greater than a maximum allowable microwave energy leakage value.
