Abstract: A continuous system for heating articles that pass through an oven cavity heated by microwave energy. A conveyor used to continuously feed items through the oven cavity contains one or more dividing mechanisms arranged along its longitudinal axis. The dividing mechanism(s) prevent at least some of the articles from touching one another while being heated. The dividing mechanism may take the form of one or more o-ring cord dividers that are wrapped around and driven by the conveyor. In an alternate embodiment, the dividing mechanism may comprise a plurality of molds defining a specific outer contour for the articles to be heated.
