EXPLANATION OF MICROWAVE COOKING AND CONVECTION COOKING

The Sharp Convection-Microwave oven uses microwave
energy and the sheath heater to produce heat in the food to
be cooked.
Unlike conventional ovens, microwave energy will cook
foods without applying external heat.
Microwaves which are short electromagnetic waves of RF
(radio frequency) energy, pass through materials such as
glass, paper, china, and most plastics. Materials such as
metal and aluminum foil tend to reflect microwaves and
may be used only as recommended in the cooking
instructions.

CHAPTER I
PRODUCT DESCRIPTION
Materials with a high moisture content, like most foods,
will absorb microwave energy. As the microwave energy,
at a frequency of 2,450 Megahertz enters the food, the
molecules align themselves with the energy. However,
cooking by microwave energy only, produces no brown-
ing or searing (unless cooking a roast of sufficient thick-
ness). This microwave oven is, therefore, equipped with
a sheath heater to provide browning of the food.
The combination of the heater plus high-speed circulation
of air by a circulating fan around the food provides fast
cooking and browning of foods conventionally with or
without the addition of microwave energy.
