  • Patent number: 8863652
    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.

  • Publication number: 20090165778
    Abstract: A char-broiler for cooking a food product having a housing, a plurality of burners disposed within housing that defining a cooking zone. The char-broiler also provides for a manifold and at least one valve associated the plurality of burners in the cooking zone; and at least one cover that has a deployed position to cover the plurality of burners in the cooking zone and a non-deployed position to uncover the plurality of burners in the cooking zone. The least one cover is capable of adjusting the flow of gas through at least one valve based on a position of the at least one cover, the temperature in the cooking zone or both position of the at least one cover and a temperature in the cooking zone.

  • Patent number: 6805112
    Abstract: A convection oven having multiple airflow patterns within a cooking chamber during a baking cycle. In one embodiment, at least one reversible blower wheel rotatable at varying speeds produces separate airflow states to create multiple airflow patterns within the cooking chamber during a baking cycle. In another preferred embodiment, at least one adjustable airflow control surface mounted within the cooking chamber creates multiple airflow patterns within the cooking chamber during the baking cycle.

  • Patent number: 6557543
    Abstract: A convection oven having a high pressure duct distribution system to produce airflow within a cooking chamber of the convection oven. The high pressure airflow is easily tuned to produce a precise airflow pattern within the cooking chamber by opening and/or closing individual nozzles which extend from a duct of the duct distribution system into the cooling chamber.

  • Patent number: 4601237
    Abstract: An adjustable meat press for two-sided cooking of food products is disclosed, characterized by a movable cooking device having a planar heated cooking surface which is connected with a grill having a fixed heated cooking surface for pivotal movement between open and closed positions. The movable cooking device includes a plurality of incrementally adjustable cams having a camming surface which protrudes beyond the cooking surface of the movable device to space the movable cooking surface from the grill cooking surface by a selected distance. Owing to the provision of a plurality of cams, the movable cooking surface is accurately maintained parallel to the grill cooking surface when the movable device is in its closed position to uniformly press and cook one or more food products arranged therebetween. A unique spring and slide mechanism controls the movement of the movable cooking device relative to the grill between the open and closed positions.
