Abstract
In apparatus for deep fat frying, control circuitry is provided for regulating the temperature of heating elements. During cooking the heating elements are immersed in cooking fluid and are maintained at a selected temperature by an operating thermostat. Two high limit thermostats are provided to turn off the heaters if the temperature exceeds a predetermined safe limit. For cleaning, the heating elements are raised out of the cooking fluid and automatically disconnected from the operation and first high-limit thermostats. The heaters are cyclically actuated and deactuated by a thermal time delay relay, gradually raising the heater temperature to achieve pyrolytic cleaning of the heating elements. The second high-limit thermostat turns off the heating elements when a predetermined temperature is reached, ending pyrolytic cleaning.
