  • Patent number: 10123548
    Abstract: An anti-oxidation frying device includes a frying vessel having an electrically conductive body configured to heat cooking oil carried therein by a heating unit. A removable basket, also formed of electrically conductive material, is configured to be carried within the frying vessel to enable the cooking of food in the heated oil. A rectification circuit is coupled to the heating unit, the body of the frying vessel, and the basket. During operation the rectification circuit converts AC power from an external power source into a rippled, rectified AC current signal that is supplied to the heating unit, body of the frying vessel, and the basket, so as to create a reducing environment of available electrons for absorption by the cooking oil and food as it is prepared, thus extending the life of the cooking oil.

  • Patent number: 6505546
    Abstract: A vessel for cooking food under pressure wherein the shape of a bottom surface of the vessel and the position of heating elements which heat cooking fluid contained within the vessel act to form a cool zone in a region near the bottom surface. Within the cool zone, the temperature of the cooking fluid is maintained below the cooking temperature so that food particles dislodged from the food being cooked do not burn and contaminate the cooking fluid. In addition, the temperature in the cool zone is maintained above the boiling point of water so that moisture contained within the food particles is continuously evaporated during the cooking cycle, preventing boil over conditions. A novel pressure release system is provided for intermittently operating a pressure release valve near the end of the cooking cycle. A computer controller controls operation of the release valve based upon the temperature of the cooking fluid to eliminate sudden drops in temperature.

A combination of gears and a drive chain transfers the rotational movement of the drive shaft to rotational movement of the jacking screw, and a shielding sleeve engages threads on the jacking screw, such that the sleeve is raised or lowered by the rotational movement of the jacking screw. Each sleeve includes a fixing pin or bolt for engaging a basket mounting hinge.

  • Patent number: 6293188
    Abstract: The invention provides a device for signaling a cooking state for at least one cooking item, such as an egg, a potato, a pepper, rice, noodles, that are being cooked in a liquid cooking medium. The device includes an at least partially floating jacket, a temperature sensor arranged in thermally conductive communication with the floating jacket, an analog-to-digital converter, a digital computing unit and a signaling device. The digital computing unit includes a digital delay portion to delay a temperature value of the liquid cooking medium that is measured by the sensor and digitized with the analog-to-digital converter. The delay portion has at least one thermal time constant to provide a thermally delayed inner temperature value as an output of the delay portion. A switching device is provided to activate the signaling device once a first temperature threshold is reached by the output of the delay portion, for signaling a first cooking state of the at least one cooking item.

  • Patent number: 6269737
    Abstract: A cooking apparatus includes a container, a spigot, a lid, and a food support. The container has a bottom surface and a side wall that extends upwardly from the bottom surface to a top edge of the side wall. The spigot is attached to the container side wall and has a valve member that is selectively positionable between opened and closed positions. The spigot valve member allows liquid contents of the container to drain from the container when in the opened position, and prevents the contents from draining out of the container when in the closed position. The food support is comprised of a perforated horizontal member with a perforated side wall extending upwardly from the horizontal member. A plurality of vertical members spaced around the periphery of the horizontal member extend upwardly from the horizontal member.

  • Patent number: 6162478
    Abstract: The invention relates to a process for preparation of hen's eggs during which the eggs are put into a cooking chamber of an egg-cooking container (2) closeable by a cover (8), which chamber contains a liquid heat-supplying medium, preferably water. The preparation temperature during a first preparation stage is below the boiling temperature of the water, and during a following second preparation stage is held below the temperature of the first preparation stage but above 55.degree. C. During the first preparation stage, the water starts at a temperature of approx. 55.degree. C. and is heated at a high heating rate to a temperature of at least 90.degree. C. during a first period with the result that the eggs rapidly reach a core temperature of approx. 58.degree. to 75.degree. C. At the start of the second preparation stage, the water temperature is reduced at a high cooling rate to a final temperature of between 80.degree. C. and 55.degree. C.

  • Patent number: 5931081
    Abstract: The present invention features an electrical, frying appliance that uniformly cooks food items placed within its food basket. This frying appliance automatically immerses and extracts the cooking basket into and out of an aluminum oil bowl containing heated oil. In this fashion, the food in the basket is uniformly fried during the cooking cycle. The frying appliance contains a translationally movable basket that operates by a transmission wire driven by a shaft. The translational movement of the food basket allows the food in it to lie flat as it is immersed in the aluminum oil bowl. The food basket remains substantially horizontal during its movement between its immersed and non-immersed positions. In this fashion, the food items are prevented from shifting around in the frying basket. This allows the food to fry evenly within the basket and, when cycled, to be drained of oil periodically.
