  • Patent number: 8642929
    Abstract: A steaming oven having a collector plate disposed in an oven chamber. A collector plate is disposed above a boiling water reservoir in the oven chamber. The collector plate has a drain tube inserted into an overfill tube. Waste material from the steam and food droppings is conveyed from the oven chamber via the drain tube and the overfill tube. A barrier shields one or more water level probes or sensors from water turbulence, thereby providing reliable water level sensing by the water level probes or sensors.

  • Patent number: 8304697
    Abstract: A smoker device having a low profile fits beneath the lower most rack of an oven thereby allowing full use of all possible shelves of the oven. The smoker device comprises a uniquely shaped bi-level heater element that allows the smoker device pan to be cradled just above the bottom wall of the oven chamber. A method and system allow a processor control of the smoker device manually or automatically as a part of a programmed recipe.

  • Publication number: 20030024922
    Abstract: The present invention generally relates to a system and method for a table top food warming system for applying steam to various sized portions of food for cooking of the food, as well as injecting steam into the food itself to increase its internal temperature. A preselected amount of water is transported via a pump to a preheated steam chamber. Upon contact with the preheated steam chamber, the water is vaporized and exits as steam through holes in a portion plate holding the food serving.

  • Patent number: 4011805
    Abstract: A convection steamer apparatus and method having improved heat-transfer characteristics for rapidly and effectively processing food items or the like at atmospheric pressure and at a relatively low constant steam temperature comprising a steam generator and distribution system for delivering steam in a turbulent controlled path to a heating chamber. A diffuser device acts to introduce substantially dry steam into the distribution system and a pressure differential generator device communicates with the chamber for continuously inducing a pressure differential to continuously purge air and/or unused steam from said chamber to maintain turbulent, generally orbital flow of dry steam in heat-transfer relation around the food items to be processed.The invention further contemplates an improved construction for an atmospheric closure for fluid and heat sealing of the heating chamber during the processing of such food items or the like.
