  • Patent number: 11700967
    Abstract: A method and apparatus for filling a steam chamber. In one exemplary embodiment, a steam chamber is placed in selective communication with a vacuum pump and a heat transfer medium, such as a source of deaerated water. The steam chamber is then placed in communication with the vacuum pump, which draws a vacuum on the steam chamber and begins removing air from the interior thereof. Once a sufficient vacuum has been drawn on the steam chamber and substantially all of the air removed therefrom, the steam chamber may be placed in communication with the heat transfer medium. In one exemplary embodiment, the heat transfer medium is deaerated water. A predetermined amount of heat transfer medium is then allowed to fill the steam chamber. Once the predetermined amount of deaerated water has been received within the steam chamber, a steam chamber may be sealed.

  • Patent number: 7156087
    Abstract: An outdoor multi-method cooker for preparing a wide variety of different foods at the same time using selective convection, radiant, or conduction cooking operations with or without smoke, or combinations thereof, using a single heat source. The cooker has a horizontal central longitudinal chamber with a firebox at one end and a pair of stacks at the opposed end, a main oven, a pair of lateral smokeless ovens, a warming compartment, and a griddle above the firebox, all disposed transversely on the longitudinal chamber in parallel spaced relation, and a steam table along the upper portion of the longitudinal chamber. The cooker operates on the principle of equalization of natural differential pressures caused by rising warmer air, similar to the draw created by the upper portion of a fireplace, for drafting hot gases or smoke laden hot gases from the combustion source and selectively routing it through passageways into and around the various components.

  • Patent number: 5467697
    Abstract: A chafing dish assembly which contains a pair of rings that support a pair of heating elements located below a water tray. The water tray is elevated above the heating elements by a frame supported by a pair of pivoting legs. Located within the water tray are a pair of food dishes. The heating elements heat the water within the tray, which heats the food within the dishes. The frame has a bent top edge which provides a ledge for the water tray. The rings are cantilevered from the frame so that the weight of the heating elements deflect the rings away from the water tray. The height of the flame and the weight of the heating elements decrease as the fuel within the elements becomes expended. The reduction in the weight of the heating element induces an upward movement of the rings toward the water tray, wherein the smaller flame is moved into closer proximity with the tray to provide a more uniform heating process of the food.

  • Patent number: 5381729
    Abstract: The warming device of the present invention includes a food tray or pan formed from metal so as to promote the conduction of heat to the food contained in the pan. The pan is held within a sump vessel adapted to contain a heat transfer fluid such as water. The sump vessel is a unitary bowl-shaped container having side and bottom walls and an upper open wide mouth for receiving the food pan whereby the food pan, when inserted, is located within the sump vessel so that the bottom portion of the food pan is spaced from the wall of the sump vessel to define a chamber suited for containing water and steam between the sump vessel and the food pan. The sump vessel has heat-insulating qualities that reduce heat loss and promote the transmission of heat to the food pan. A heat dissipator plate formed from a metal or other conductor of heat is connected to a wall of the sump vessel with an air space between the heat dissipator plate and the sump vessel.
