摘要： A conveyor oven has a modulating gas valve which raises and lowers the thermal output of a burner that heats the oven. A bypass line passes a minimum amount of gas to prevent the burner from completely shutting down during periods while the oven remains above a threshold demand for more heat. Electrical isolation is provided between temperature controlling devices to prevent an electrical feed back which might otherwise prevent a complete shut down of the oven during hazardous conditions.

摘要： An automatic oven cooks or bakes a food product over a timed period of time during which a burner delivers heat to the oven cavity. Thermocouple sensors in the cavity control a modulator which regulates the amount of gas flowing to the burner to maintain a uniform temperature in the oven. A conveyor carries the food product in order to time the baking period.

摘要： A conveyor oven includes a controller configured to change the operation of a first set of burners and a second set of burners from a cooking mode to an energy saving mode based at least in part upon detection of the absence of food in the oven chamber. The first set of burners operating at a first intensity during the cooking mode and are off during the energy saving mode. The second set of burners operating at a first intensity during the cooking mode and being adjustable to a different intensity during the energy saving mode, where the second set of burners produce heat during the different intensity.

摘要： A plurality of small, low cost conveyor toaster/ovens can be stacked with substantially no physical spacing required between the units. In part the stackability results from a blower/fan that drives cooling air through a common plenum surrounding the conveyor. The cooling air is sucked into one side of the unit and then divided between the lower motor compartment and the upper air plenum flowing over the top and bottom of the oven. The air is then recombined to cool the rear compartment and exits the unit via several vents in the back and opposite side of the oven. A control panel enables the user to pre-select different menu schedules which can be modified, as required. Each selection is identified by a single digit on a key pad in the control panel. The actual temperature within the toaster/oven is sensed by a thermocouple in contact with the heater element sheath. The control converts the stored data via a mathematical function and in response to temperatures sensed on the heater. In order to provide both toasting and hearth baking the conveyor may be equipped with either of two types of endless belts, one being a tightly woven herringbone belting material that hearth bakes the food product. The other type of endless belt is made of an open wire link belting material.

摘要： A conveyor toaster has air chambers at opposite sides and at the top of the oven for reducing surface temperatures of the out side housing panels of the oven which a worker might touch. A wire link conveyor belt extending through the oven and carrying food products at a speed which toasts those food product during their dwell time within the oven. The conveyor belt is tensioned by a spring bias so that a force directed against the spring bias creates a slack which enables an installation, removal, and reinstallation of the conveyor belt. A heating element is supported at a height above the belt which may be during manufacturing to accommodate the height of a food product conveyed by the conveyor. A loading rack at the front of the housing has two stable positions for enabling either batch loading or continuous loading.

摘要： A multi-zone restaurant type of griddle is modularly constructed so that all maintenance may be done at the front of the griddle housing. The griddle plate is only three-eights of an inch thick with heat being spread uniformly by an aluminum plate in intimate contact with the bottom of the griddle plate. A thermocouple temperature sensing element is located at the bottom of a hole in the underside of the griddle plate so that the element is very near the cooking surface and is sensitive to the temperature of the load on the cooking surface, as distinguished from being sensitive to the temperature of the heating element below the griddle plate. With the modular construction, the front access, and light weight, all of the repairable parts of the griddle may be removed and replaced by one man as distinguished from most prior art griddles where two-man service teams were routinely required because they had to lift and invert a very heavy griddle which had a very thick steel griddle plate.

摘要： A control device for a multi-zone conveyor oven constructed according to the present invention comprises a microprocessor-based controller, appropriate control software, a keyboard and display for interaction with a user, means for sensing the conveyor speed and the heating chamber temperature, and means for controlling the power supplied to the conveyor motor and the heating elements. The controller provides facilities for user programming of sets of oven parameters, each set corresponding to a particular food product to be cooked in the oven. Each set of parameters includes the total cook time for the product and a desired temperature which is independently selectable for each heating zone. Once a set of parameters has been programmed, it is assigned to a particular key on the keyboard, and the user may select that entire set of parameters by simply pushing the assigned key. The parameters are stored in the EEPROM to prevent their loss during electrical power interruptions. High-accuracy, low hysteresis temperature control of the oven is provided by pulse-width-modulating the power supplied to the heating elements. Accurate and repeatable control of cooking time is provided by controlling the speed of the motor driving the product transport conveyor. Such control is provided by pulse-width-modulating the power supplied to the motor according to motor speed information derived by sensing the motor shaft position. The controller also provides extensive fault detection, and degrades oven performance as gracefully as possible.
