Abstract
An improved magnetic field stop. The field stop adjusts to allow different sizes of products to be passed through a microwave heating system. The field stop prevents undue radiation from escaping a heating chamber which is used in a microwave heating process for a variety of substrates.
Claims4
A field stop system for use with a heating enclosure that heats an object with microwaves, the system comprising:
- one or more microwave resonators;
- a positioning mechanism coupled to the microwave resonators for moving the resonators in relation to the object;
- and
- a sensing and controlling system coupled to the positioning mechanism for determining a position of the microwave resonators relative to the object and, in response, causing the mechanism to move the resonators in relation to the object.
