4. Fittings and operation of the EDG 6500.0
The water in the water tank is turned into steam with the electric valve located on the steam generator.
A hose transports the water from the tank into the inside of the oven. An evaporation plate is located in
the bottom part of the oven. When water drips onto the hot plate it is immediately converted into steam.
It is therefore not necessary to fill water into the cookware. A pressure flap is closed to keep this steam
inside the oven. The pressure flap has several holes which prevent pressurisation and regulate the
pressure system.
The principle is not the same as for cooking in a pressure cooker, since here the internal pressure
exceeds the atmospheric pressure. The steam oven firstly fills up with steam and the temperature almost
reaches 100°C. An electric heating pad has been installed in the top part of the oven in order to avoid
condensation. A cross-flow cooling fan constantly cools the appliance and the pressure flap opens
three minutes before the cooking cycle is completed, hence enabling steam to escape. A safety
thermostat (210°C) protects the appliance from becoming overheated and two sensors located inside
the oven and in the steam generator constantly monitor the temperature.
