OPERAITON 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 is 3 properties of microwave, that is
a) Absorbability: the microwave can cause the excess vibration of molecule of various food so as to obtain the
heating 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.
NSTALLATION OF MICROWAVE OVEN
1) To ensure sufficient ventilation, the distance from the back of microwave to the wall should be above10cm,
the side to the wall above 5cm, the top to the ceiling above 20 cm.
2) Do not place any objects on the top of microwave oven.
3) Keep the microwave oven far from the TV, Radio or antenna as picture disturbance or noise may occur.
4) Keep the plug accessible to the socket.
5)This is designed as a freestanding style and should not be placed in a cabinet.
UTENSILS GUIDELINE
It is strongly recommended to use the containers which are suitable and safe for microwave cooking. Generally
speaking, the containers which are made of heat-resistant ceramic, glass or plastic are suitable for microwave
cooking. Never use the metal containers for microwave cooking and combination cooking as spark is likely to
occur. You can take the reference of below table.
Material of container Microwave
Notes
Ceramic
Yes
Never use the ceramics which are decorated with metal
rim or glazed
Heat-resistant plastic
Yes
Can not be used for long time microwave cooking
Heat-resistant glass
Yes
Grill rack
No
Plastic film
Yes
It should not be used when cooking meat or chops as the
over temperature may do damage to the film
FOR THE FIRST USE
As there is manufacturing residue or oil remained on the oven cavity or heat element, it usually would smell the
odor, even a slight smoke, It is normal case and would not occur after several times use, keep the door or
window open to ensure good ventilation. So it is strongly recommended to place a cup of water in the turntable,
setting at high power and operate for several times.
