MICROWAVE OVEN
Dear Buyer!
We congratulate you on having
bought the device under trade name
“Saturn”. We are sure that our
devices will become faithful and
reliable assistance in your
housekeeping.
Avoid extreme temperature changes.
Rapid temperature change (e.g.
when the unit is moved from
freezing temperature to a warm
room) ma y cause con densatio n
inside the unit and a malfunction
when it is switched on. In this case
leave the unit at room temperatu re
for at least 1.5 hours before
switching it on.
If the unit has been in transit, leave
it indoors for at least 1.5 hours
before starting operation.
OPERATION THEORY OF
MICROWAVE OVEN
1. Microwave is a kind of high frequency
electromagnetic wave, which is
commonly distributed in the nature. But
the existing form of microwave is
dispersed so that it cannot be collected
together for heating purpose. The key
component of magnetron of microwave
oven will transform the energy of
electricity to microwave and huge energy
of microwave field is established under
the closed cavity. So the molecule of food
is caused to vibrate at very high speed
and the friction heat produced will cook
the food in a fast way.
2. There are 3 properties of microwave,
that is:
a) absorbability, the microwave can
cause the excess vibration of molecule of
va r i o u s fo o d s o as to o b t a i n th e h e a t i n g
purpose. But the infiltration ability is
largely depend on the size, thickness and
properties of the food.
b) penetrability, microwave can
penetrate through ceramics, glass,
temperature-resistant plastics. It is
required to use the containers whose
material have good microwave
penetrability to achieve best heating
result. See the below utensils guide.
c) reflectivity, microwave would be
reflected by the metal wall of interior
cavity so as to establish an even
magnetic field, thus can prevent the
overheating of partial area.
