摘要： A conveyor oven having a heating chamber and an oven chamber. A conveyor is disposed in the oven chamber to convey food products between an entry port and an exit port. An air impingement assembly is disposed to provide jets of impingement air toward the food product. A fan blower, a heater and a moisture delivery device are arranged to provide heat and moisture to an airflow to the air impingement assembly so that the jets of air are heated and laden with moisture and provide as a blanket-like mixture of air and moisture at the surface of the food product.

摘要： A convection oven with laminar airflow and/or moisture injection. A radial airflow fan is used to provide a circulating airflow that is substantially even and substantially turbulence free. The circulating airflow is provided to an oven chamber via a plurality of egress ports that rim a divider wall disposed between the oven chamber and a fan chamber. The airflow interleaves with a plurality of pans in the oven chamber to provide a laminar airflow. Moisture is injected into the circulating airflow either upstream of the fan or by flashing water onto the hot blades of the fan from either the low pressure side or the high pressure side of the fan.

摘要： A combination microwave gas convection oven having a tubular burner operating in an induced draft environment. A blower system draws air from a combustion chamber forcing it into the heating cavity. The slight pressure created in the combustion chamber draws in air from the heating cavity through perforations communicating therebetween completing the convection recirculation. The negative pressure in the combustion chamber also causes secondary combustion air to be drawn up along the sides of the burner which is positioned adjacent to an aperture in the floor of the combustion chamber. A plurality of top ports in the burner provides low port loading. The structure provides good flame characteristics with low noise of combustion.

摘要： A gas-fueled oven which is capable of safely assuming high temperatures such as occur during pyrolytic self-clean cycles and which employs a single multi-purpose fan for directing cool air flows over wall surfaces, for providing aspiration and temperature dilution of hot flue products, and for providing combustion air for a power broiler burner.
