How your microwave oven works

Microwave ovens are safe. Microwave energy is not hot It causes food to make its own heat, and it’s thus heat that cooks the food

Mode Mixer

Magnetron

Ceramic

Bottom

Oven Cavity

Metal Floor

Microwaves are like TV waves or light waves. You can’t see them, but you can see what they do.

Microwaves pass through glass, paper and most plastics with- out heating them so food ab- sorbs the energy. Microwaves bounce off metal pans so food does not absorb the energy.

A magnetron in the micro- wave oven produces micro- waves. The microwaves move into the oven where they are scattered or stirred by a mode mixer (like a fan). Microwaves bounce off metal oven walls and are absorbed by food.

Microwaves may not reach the center of a roast. The heat around the outside is what cooks the roast all the way through. This IS one of the rea- sons for letting some foods [roasts, baked potatoes] stand for a while after cook- ing, or for stirring some foods during the cooking time.

The ceramic bottom of your microwave oven lets micro- waves through. Then they bounce off a metal floor, back through the ceramic bottom and are absorbed by the food.

The microwaves		disturb
water	molecules	in the	food.
As the	molecules	bounce
around	bumping	into	each

other, heat is made, like rub- bing your hands together. This is the heat that cooks.
