Microwave power

How it works
The Speed Oven contains a high-
frequency tube called a magnetron. It
converts electrical energy into
microwaves. The microwaves are then
distributed evenly throughout 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 container being used.
Microwaves can penetrate porcelain,
glass, cardboard and plastics, but not
metal. Do not, therefore, use dishes
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
billion 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 center. The
moisture, fat and sugar content of food
will affect the speed at which it is
cooked.
Advantages
– Food can generally be cooked with
little liquid or oil.
– Defrosting, heating and cooking is
faster than using a conventional
oven.
– Nutrients, such as vitamins and
minerals, are generally retained.
– The color, texture and taste of food
are not impaired.
Microwaves stop being produced
when the program is interrupted or the
door is open. While in operation the
closed, sealed door prevents
microwaves from escaping the
appliance.
