    Abstract: A convection heating apparatus with smoke and grease management means and an improved temperature controlled gas delivery system. The apparatus includes an exterior cabinet, an interior chamber and intermediate walls disposed between the exterior cabinet and interior chamber such that an intermediate cavity is provided between the interior chamber and intermediate walls and an outer cavity is provided between the exterior cabinet and intermediate walls. The apparatus further includes a product support, preferably a conveyor, disposed in the interior chamber. A blower for circulating temperature controlled gas into said interior chamber is also provided which is in fluid communication with at least one duct (preferably a plurality) having a jet plate with orifices positioned to direct temperature controlled gas toward the product support. A second blower is provided for circulating air through the outer cavity and intermediate cavity to cool the exterior cabinet walls and interior chamber walls. An improved air delivery duct is provided having a dual taper resulting in uniform distribution of the temperature controlled gas to a food product. An air filtering system is also provided comprising a perforated filter plate or louvers and/or catalytic converter disposed in the temperature controlled gas return path.

    Abstract: Apparatus to transfer heat to the surface of a product includes a product support, a duct having a duct entrance, a duct outlet and a longitudinal duct axis and a plenum for delivering temperature controlled fluid into the entrance of the duct such that fluid flows longitudinally of the duct toward the outlet. A perforated plate has at least one orifice, having an orifice axis extending generally toward a product support for forming a jet of fluid, having a jet axis, flowing in a predetermined direction. The longitudinal duct axis of the duct is rotated relative to the orifice axis for changing the direction of the jet axis relative to the orifice axis for moving the jet axis relative to the product support.

    Abstract: A combination microwave and air impingement oven has two magnetrons and an air handling system that includes two or more reciprocating ducts through which air is dispensed into the oven. The rotating ducts are configured to stir microwave energy in the oven to prevent formation of hot spots and to sweep microwave radiation over the surface of the food product. A foraminous partition, configured to encircle a portion of the cooking chamber, has a central portion and extremities mounted to divide the interior of the cabinet into a cooking chamber and an air heating chamber. The partition extends around a major part of the periphery of the cooking chamber such that air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.

    Abstract: The invention is an apparatus and method for measuring the heat transfer and the rate of heat transfer in thermal exchange processes such as food processing, thermosetting of plastics, and freezing processes. The apparatus comprises a target module and a data recording module. The target module comprises a target having a known mass and known thermal characteristics. The black body edge effects of the target are minimized by an edge shield positioned adjacent to the target. The edge shield is physically separated from the target so that conductive heat transfer between the two elements is minimized. The edge shield supports the target such that at least one surface of the target is exposed to the surrounding environment. A temperature sensor measures the change in temperature of the target. The data recording module may be insulated so that the calorimetric data may be recorded in extreme temperature environments.
