Steam reduction
If a cooking temperature above approx.
80 °C has been set, the appliance door
will automatically open a fraction just
before the end of a cooking programme
to release some of the steam from the
cabinet.
Steam reduction
will appear in
the display. The door will then close
again automatically.
Steam reduction can be switched off if
you wish (see "Settings - Steam
reduction"). If switched off there will be
a lot of steam emitted from the cabinet
when the door is opened.
Microwave power
How it works
In the steam oven with microwave there
is a high-frequency tube called a
magnetron. This converts electrical
energy into microwaves. These
microwaves are distributed evenly
throughout the oven interior, and
rebound off the metal sides of the oven
interior to reach the food from all sides.
In order for microwaves to reach the
food, they must be able to penetrate the
cooking utensil being used. Microwaves
can penetrate porcelain, glass,
cardboard and plastics, but not metal.
Do not, therefore, use utensils made of
metal, or which contain metal, for
example in the form of gold or silver
trim. The metal reflects the microwaves
and this could cause sparking. The
microwaves cannot be absorbed.
Microwaves pass through a suitable
container and find their way directly into
the food. All food contains moisture
molecules which, when subjected to
microwave energy, start to oscillate
2.5 thousand million times a second.
The friction caused by this vibration
creates heat, which first starts
developing around the outside of the
food and then slowly penetrates
towards the centre. The moisture, fat
and sugar content of food will affect the
speed at which it is cooked. The heat is
generated in the food itself.
Advantages
Food can generally be cooked without
adding much liquid or cooking oil.
Microwaves stop being produced as
soon as the cooking process is
interrupted or the appliance door is
opened. When the appliance is in
operation, the closed, sealed door
prevents microwaves escaping from
the appliance.
