MICROWAVE OVEN

摘要

An oven for heating food has a cooking chamber through which air may be circulated by means of a blower in a blowing housing. A collector for collecting airborne particles is disposed in an air return path located between the cooking chamber and the blower housing. The collector is maintained at a temperature less than the temperature of the circulating air to collect airborne particles adjacent the collector. The oven may be used in or form part of 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.
