    摘要: 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.

    摘要: A method and apparatus for heating a product which includes a plurality of tapered ducts in a cabinet above and below a conveyor to form streams which are directed toward the product. Spent air is drawn through return ducts which have intake openings centered between entrance and exit openings in the cabinet and centered between lateral edges of a conveyor and between the tapered ducts to provide a balanced flow of spent air in the cabinet to the return opening. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a conveyor extends to cause most of the heated air to be drawn to the return duct opening and to maintain internal pressure in the cabinet to prevent ingress and egress of air through the opening.

    摘要: A method and apparatus for heating or cooling a product which includes a plurality of tapered ducts in cabinet above and below a turntable to form streams which are directed toward the product. Spent air is drawn through intake openings in return ducts in the cabinet. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a product is loaded on the turntable in a loading zone to cause most of the heated air to be drawn to return duct openings and to maintain internal pressure in the baking zone in the cabinet to prevent ingress and egress of air through the loading opening. Orifices are formed in a circular array of rings such that the sum of the areas of orifices in each ring spaced from the axis about which the turntable rotates is substantially equal.

    摘要: 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.
