OPERATION THEORY OF MICROWAVE OVEN
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.
There is 3 properly 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.
Installation of Microwave Oven
1) To ensure sufficient ventilation, the distance of back of oven to the wall or cabinet should be at
least 10 cm, side of oven to the wall or cabinet should be at least 5 cm, the top of oven to the ceiling
or cabinet should be at least 20 cm.
2) Do not place any object on the top of oven.
3) The position of the oven shall be such that it is far from the TV, Radio or antenna as picture
disturbance or noise may occur.
4) The oven shall be so installed that the plug is accessible.
Utensils guide
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 is 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 Micro

Never use the ceramics which are decorated with metal
rim or glazed .
Can not be used for long time microwave cooking.
It should not be used when cooking meat or chops as
the oven temperature may do damage to the film
