Abstract:
A cooking device that is capable of rapidly cooking food products such as in toasting bread products or cooking pizza. The cooking device uses air impingement from above and/or below the food product. In some cases an infrared heater is additionally used to impart a desired color and crunchiness about a surface of the food product. In some cases, a boost in thermal energy is applied to the bottom of the food product vis-à-vis the top thereof. In some cases, the boost is due to an extra heater, which may be gas or electric. The device is particularly adapted for toasting bread products, cooking sandwich products (toasting the bread and heating the sandwich filler) and/or cooking pizza. Rapid cooking times are achieved by delivering more thermal energy to the top or bottom of the food product, depending on the type thereof, to give quality and speed. For example, a pizza can be cooked to have a crisp bottom without burning a cheese topping.
Abstract:
Coatings containing at least 85% by volume crystalline mullite with less than 15% by volume of amorphous material and mullite dissociation phases are plasma sprayed onto the surface of a silicon based ceramic substrate by closely controlling the plasma spray parameters including the mullite feed stock and its particle size, the nozzle outlet stand-off distance, movement of the substrate past the plasma flow, back side heating of the substrate and the powder feed rate through the plasma spray gun.
Abstract:
A combination convection/microwave oven in which a food product is cooked by microwave energy from a source thereof and by a heated airflow provided by a thermal energy source and a blower. The food product is located in the near field of the microwave energy. The oven includes a controller that operates the thermal energy source and/or the blower according to temperature and or time to improve cooking results. The cooking procedure includes a soak interval during which the thermal energy source, the blower and/or the microwave energy source is turned off, whereby the temperature of the food product is permitted to equilibrate and thereby provide more uniform cooking. The food product may be located directly on the rack or in a microwave transparent or reflective container.
Abstract:
A combination convection/microwave oven in which a food product is cooked by microwave energy and by a heated airflow provided by a thermal energy source and a blower. The oven is capable of cooking food in a microwave reflective pan. Microwave energy enters the oven below the pan and is guided to a spacing between the pan and oven sides and then reflected by the sides and top of the oven to the food product in the pan. The heated airflow is laminar with an upper layer and a lower layer. The pan is positioned at about the interface of the two layers so that the upper layer is incident on the food product and the lower layer is incident on the bottom of the pan.

Abstract:
A combination oven that is operable with convection air, impingement air and microwave energy in various combinations thereof. The oven has an oven chamber and a fan box that are located front to back. A fan in the fan box circulates heated air by discharging via openings in a top and a bottom and taking in via an intermediate opening of a baffle plate. Impingement plates are easily installed and removed in the oven chamber to provide impingement air upwardly or downwardly. At least one of the impingement plates is installed and removed by a sliding motion. Microwave energy is provided through the side walls of the oven chamber.

Intake ports for cooling air are located in a bevel between the side walls and bottom wall of the oven's outer enclosure so as to allow the oven to be located right next to other structures, such as a wall. An interlock assembly is also provided for the oven door.

Abstract:
Cooking apparatus having first and second platens with product recognition. A positioning mechanism moves the second platen toward the first. A detector senses the second platen making contact with a food product disposed on the first platen and provides a signal. A controller uses the signal to measure the travel distance of the second platen. The product thickness is a function of the travel distance, which is used to select a cooking procedure for the food product. The controller then executes the selected cooking procedure to cook the food product. The detector can include a micro switch, proximity sensor, touch sensor, strain sensor, thermal sensor, optical sensor, sonar sensor or positioning load change sensor.
