Abstract: The skillet of the present disclosure includes a pan, a lid, and a gasket so that when the lid is placed on top of the pan, the lid is sealed to the pan because of the gasket. An interior space is defined, so that water and food product to be cooked can be placed therein. A fan is connected to the lid and circulates air within the interior space. A heating element supplies heat energy to the pan. A pressure release valve is connected to the lid, as is a pressure sensor. A controller can receive pressure readings from the pressure sensor, and control the heating element, fan, and pressure release valve to keep the pressure in the interior space within a desired level.

Abstract: A steam-jacketed kettle for cooking food includes a combustion chamber below the steam jacket. The combustion chamber is provided with an atmospheric gas burner for heating water in the steam jacket. The burner is disposed in an offset location at one side of the combustion chamber and a series of flue gas outlets are provided at the opposite side of the combustion chamber so that combustion gases tend to wash across the bottom wall of the steam jacket, for even heating. The flue gas outlets communicate with respective flue pipes that extend back through the steam jacket to a common flue gas collector, so that additional heat can be transferred from the gases in the flue pipes to the steam jacket.

Abstract: A cooking vessel includes a kettle partially surrounded by a vapour jacket. An evaporator for containing fluid is mounted to the kettle and includes a tubular portion and is in fluid communication with the jacket to act as a vapour source for the jacket and to receive condensed fluid from the jacket. A burner is mounted to the kettle and located within the tubular portion of the evaporator.
