Recycling cooking oven with catalytic converter

摘要

A recycling cooking oven for cooking at least in part by hot air impingement and providing a substantially closed environment, comprises: a) a cooking chamber 22 is for receiving a stream of hot air from a thermal plenum 20 via a plurality of openings in a top of cooking chamber 22; b) a thermal plenum 20 is located upstream of cooking chamber 22 and includes a heating means for supplying hot air downwardly into cooking chamber 22 via the plurality of openings 30; c) means 24 is for causing the stream of hot air to circulate in substantially a continuous travel path including thermal plenum 20 and d) a catalytic converter 50 is disposed in the continuous travel path of the stream of hot air for flamelessly oxidizing oxidizable components in the hot air of the stream leaving cooking chamber 22, thereby both to remove them from the hot air of the stream and to release at least some additional heat energy into the hot air of the stream. Cooking chamber 22 cooks food therein at least partially with streams of hot air from the plurality of openings and such foods adding oxidizable components to the hot air.
