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.

HOW MICROWAVES COOK FOOD

Microwave oven is a Group 2 ISM equipment in which radio frequency energy is intentionally generated and used in
the form of electromagnetic radiation for the treatment of material. This oven is a Class B equipment suitable for use in
domestic establishments and in establishments directly connected to a low voltage power supply network which
supplies buildings used for domestic purposes.

In a microwave oven,
electricity is converted
into microwave by the
MAGNETRON.
The microwaves
bounce off the metal
walls and the metal
door screen.
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.

foods contain water to a
more or lesser extent.
