MICROWAVING PRINCIPLES

Microwave energy
has been used in this country to cook and reheat
food since early experiments with RADAR in World War ll. Microwaves are
present in the atmosphere all the time, both naturally and manmade sources.
Manmade sources include radar, radio, television, telecommunication links
and car phones.

In a microwave oven, electricity is converted into
microwave by the MAGNETRON.
The microwaves bounce off the metal walls and
the metal door screen.
Then they pass through the cooking containers
to be absorbed by the water molecules in the
food, all foods contain water to a more or lesser
extent.
ABSORPTION
Microwave Water Molecule
The microwaves cause the water molecules to vibrate which causes
FRICTION, i.e. HEAT. This heat then cooks the food. Microwaves are also
attracted to fat and sugar particles, and foods high in these will cook more
quickly. Microwaves can only penetrate to a depth of 4-5cm and as heat
spreads through the food by conduction, just as in a traditional oven, the food
cooks from the outside inwards.
