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.
CONVERSION CHARTS
In a microwave oven,
electricity is converted
into microwave by the
MAGNETRON.
REFLECTION
The microwaves bounce
off the metal walls and
the metal door screen.
TRANSMISSION
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
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 1
1 / 2 - 2 inches(4-5cm)
and as heat spreads through the food by
conduction, just as in a traditional oven, the food
cooks from the outside inwards.
