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: A method and apparatus for vending a hot food product wherein a sealed container is moved from a protective sleeve and deposited in an oven where heat is transferred to the container for initially melting a protective sealing film and then heating the food product. After the food product has been heated, the container is removed from the oven and reinserted into the protective sleeve prior to dispensing the heated food product.

Abstract: Apparatus for transferring heat between temperature controlled air dispensed from a pair of oscillating ducts and a food product in a cabinet having an interior compartment bounded by front, side and rear walls. A foraminous partition, having a central portion and extremities, is mounted to divide the interior of the cabinet into a cooking chamber and an air conditioning chamber. It is configured to encircle a portion of the cooking chamber such that the air conditioning chamber extends around a major part of the periphery of the cooking chamber wherein air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.
