Abstract: A constraint mechanism for holding products as they are processed through a microwave applicator, used specifically for constraining products as they travel on one or more continuous conveyors.

Abstract: Apparatus for pasteurizing and/or sterilizing foodstuffs. In one representative embodiment, an apparatus for pasteurizing or sterilizing a packaged foodstuff includes at least one cavity in which the foodstuff to be pasteurized or sterilized is positioned. The cavity is configured such that, as microwave energy radiates into the cavity, the cavity operates as a single-mode cavity for sterilizing or pasteurizing the foodstuff. In another embodiment, methods are provided for optimizing a microwave system for sterilizing or pasteurizing a foodstuff.

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.

Abstract: A continuous feed microwave applicator having a choke formed along a longitudinal gap. A conveyor may be fit to run along the length of the applicator, within the gap.

Abstract: A combination cabinet and folding bed wherein the bed may be stored in the cabinet. The cabinet can be used for other purposes, for example, a drop-down shelf on one or more sides can be provided. The folding bed is a unique arrangement of three pallets that can open out from the cabinet into a continuous horizontal surface or can fold back on each other in substantially a configuration and can be stored in the cabinet in an upside down configuration.
