US Patent 7105780 Cooking device and procedure

The cooking device has a tank with an electrical heater means containing a basket for the food connected to an actuator suitable for moving it between a position inside and a position at least partially outside the tank. A first temperature sensor of a portion of the tank and a timer are connected to a control for moving the basket in relation to the signals which the control receives from the temperature sensor and from the timer. In the cooking procedure when the first sensor detects the cooking temperature, the basket is lowered and, at the same time, the timer is started for a preset time period. At the end of the time period the control deactivates the heater and commands the removal of the basket from the tank.
