WHAT ARE MICROWAVES?

Microwaves are energy waves, similar to those used

for TV and radio signals.

Electrical energy is converted into microwave

energy, which is directed into the oven cavity via a

waveguide. To prevent food and grease entering the

wave guide it is protected by the waveguide cover.

Microwaves cannot pass through metal, because of

this the oven cavity is made of metal and there is a

fine metal mesh on the door.

During cooking the microwaves bounce off the sides

of the oven cavity at random.

Microwaves will pass through certain materials, such

as glass and plastic, to heat the food.

(See "Suitable Cookware" on page GB-21).

Water, sugar and fat in food absorb microwaves

which cause them to vibrate. This creates heat by

friction, in the same way your hands get warm when

you rub them together.

The outer areas of the food are heated by the

microwave energy, then the heat moves to the

centre by conduction, as it does in conventional

cooking. It is important to turn, rearrange or stir food

to ensure even heating.

Once cooking is complete, the oven automatically

stops producing microwaves.

Standing time is necessary after cooking, as it

enables the heat to disperse equally throughout the

food.
