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 directly connected to a low
voltage power supply network which supplies buildings
used for domestic purposes.
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

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

ABSORPTION
Microwave Water Molecule Absorption Vibration
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.
