Opposed Heater Type Patents (Class 99/389)
  • Patent number: 5758567
    Abstract: A toaster has electrical parts which are energized from a mains voltage. The bread is conveyed to a toasting chamber (4) by means of a lift (6) and a handle (12). In the end position of the handle (12) a main switch (SW5) is turned on, as a result of which the electrical parts can be powered from the mains voltage. The heating elements receive mains voltage via triacs controlled by a microcontroller. After completion of the toasting cycle the microcontroller turns off the heating elements, which precludes burning of the bread, even if the main switch remains in its on-position as a result of a mechanical defect. Subsequently, the microcontroller checks the presence of the mains voltage. In that case a signalling device is activated to warn the user that the mains voltage supply to the toaster has not yet been turned off.

    Abstract: A cooked food staging device and method is provided. The cooked food staging device allows previously cooked food items, particularly sandwich fillings such as hamburger patties, fish fillets, biscuits, Canadian bacon, pork sausage, eggs, chicken patties, chicken fillets and nuggets, to be stored over extended periods of time at an elevated temperature without significant deleterious effects to the appearance, taste and texture of the food while avoiding risk of bacterial contamination. The food staging device is composed of a plurality of discrete compartments bounded by upper and lower heated compartment surfaces. Food can be stored within the compartments in trays having side walls of a height such that a gap is achieved between the top of the tray and the upper compartment heated surface to limit and control the evaporation of liquid from the food stored therein.

  • Patent number: 4669373
    Abstract: A compact two-sided cooking device is disclosed for use with an existing grill to permit two-sided cooking of food products, such as hamburger patties, on a relatively limited basis. The device includes a cooking assembly having an electrically-powered cooking platen which can be selectively positioned on food products on the grill for effecting accelerated two-sided cooking thereof. The present cooking device has been particularly configured for use in conjunction with, and for rocking movement on, a commercially-sized restaurant grill, and provides greatly reduced cooking times so that a customer's order can be freshly and efficiently prepared even during relatively slow business hours.

  • Patent number: 4493308
    Abstract: A broiler for cooking food products has an upper heating unit located in a spaced relationship from the food and a lower heating unit in a close heat transfer relationship with the food. The upper unit is preferably a U-shaped radiant fire tube with a gas-fired power burner mounted at one end as a heat source. Hot flue products exiting the radiant tube are directed to the lower heating unit which is preferably a heat pipe assembly with evaporator and condenser zones for a working fluid. In one form the condenser zone includes a generally flat wall portion with a cooking surface defining a set of upwardly facing grooves. In another form the condenser zone is a series of generally parallel pipes that extend under the food in a horizontal, mutually spaced relationship. A movable rack supports the food and moves it into and out of a cooking relationship with the condenser zone of the heat pipe assembly.

  • Patent number: 4474107
    Abstract: An improved food oven and method of preparing food is disclosed characterized by a double-oven compartment structure with each compartment having multiple infrared heating rod arrays and a smoker unit adapted to prepare food disposed within the compartment. Operation of the heating rod arrays and smoker units are monitored by a novel electronic control system which permits independent baking, broiling, barbecuing, smoking and hold-warming of foods disposed within each compartment. The compartments further incorporate a unique vent system which automatically generates a convectional airflow through each of the compartments to reduce isolated temperature gradients within the compartments and effectuate a generally uniform preparation of food.

  • Patent number: 4453457
    Abstract: An oven in a cooking machine has a pair of spaced parallel endless conveyor chains mounted therein and driven by a motor. Pivotally supported baskets for holding food are connected normal to the conveyor chains. Electrical heating elements disposed between and above the baskets are supported in the oven for cooking the food products. Guide rails maintain the baskets horizontally disposed as the baskets move adjacent to the heating elements. A sauce tank disposed in one end of the oven receives the baskets containing the food products. Each of the baskets is immersed in the sauce once during each cycle of operation. To remove the cooked food products from the oven, spaced runners are shifted over the sauce tank to prevent the baskets of food products from being dipped into the sauce. A movable collar connects and disconnects the conveyor chains to the motor. A door at the front of the oven has counterweights to facilitate opening and closing of the door by an operator.

  • Patent number: 4421015
    Abstract: Food articles are heated by radiation in the near infrared wavelength range of 0.72 .mu.m to 2.5 .mu.m. Food articles can be thawed, heated or fully cooked direct from the frozen condition in this way. Hamburger patties are cooked in a conveyor cooker between rows of sources of such radiation. The sources are energized at half voltage during standby periods so that the conveyor is held at a temperature such that it has a searing effect on patties cooked by exposure to the radiation. Full energization is effected by operation of a switch in response to placement of a patty on the conveyor through a flap connected with the switch. A separate conveyor carries hamburger bun halves beneath a third row of the sources. In a static area employing sources of the radiation, reflector and screening arrangements provide even diffuse radiation in the heating zone and control of the heating effect is obtained by selective energization of the sources for selectively variable periods.

  • Patent number: 4413173
    Abstract: An electric oven toaster construction wherein an interrupt mechanism is provided for interrupting operation of a toast timer controller when the oven toaster door is opened. An interrupt lever is positioned between a door operated rod and a heat-up/cool-down bi-metal timer controller so that when the door is opened the interrupt lever moves the toasting period controller to its off position. Thus, when the door is opened during a toasting cycle operation, the toasting period controller is returned to its off position so that a user is required to reset a new full-toast cycle when the door is reclosed. This arrangement prevents undertoasted bread that could result if fresh bread is inserted in the middle of a toasting cycle.
