  • Patent number: 4839502
    Abstract: An oven that cooks foodstuffs containing water at temperatures up to 600 degrees Fahrenheit with longwave radiation generated by masking a cooking volume from radiant heating elements by blackened rigid inserts, which absorb shortwave and longwave radiation from the heating elements and uniformly reradiate the energy into the cooking volume as longwave radiation; non-condensing steam is injected into the oven until the vapor pressure of the water in the foodstuff attains a pressure at which water will migrate to the surface of the foodstuff to be evaporated; air is then passed through the oven to remove water from the foodstuff, while cooking with longwave radiation continues.

  • Patent number: 4739698
    Abstract: An apparatus for steaming food is disclosed. Food suspended within a compartment of the apparatus is cooked by steam rising from a reservoir of boiling water below. After passing through the food compartment, steam collects in a dome shaped lid where it condenses to water then which flows by means of a gutter device below the lid into channels along the food compartment walls to return to the reservoir without contacting the food.

  • Patent number: 4430557
    Abstract: A self-standing cooking apparatus is disclosed which consists of a pressurizable vessel having a door which can be latched and sealed, an integral steam-pressure source and integral upper and lower heating rod elements which serve as broil elements and bake elements, respectively, and a water-filled tray which can be disposed above the upper heating rod. An electrical control circuit enables selective energization of the bake and broil heat elements by continuous or controlled duration pulses of current which control the proportion of infrared energy that will be produced by the heating rods. The oven can be operated under pressure with the heating rods applying infrared radiation to the foodstuff being cooked in order to obtain browning or crisping of the foodstuff which is cooked at elevated pressure. The oven can also be operated in a conventional bake mode, a conventional broil mode, a steam cooking mode, a sealed cooking and warming mode and a toasting mode.

  • 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.
