1,The principle of microwave drying
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field enerLD can be converted to heat enerLD in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.

3, The principle of green tea kill out
Through the high temperature damage and passivation fresh tea of enzyme activity, inhibition of fresh leaves of tea polyphenols, enzymatic oxidation, the evaporation of moisture, make fresh leaf tea become soft, easy to RouNian forming, and at the same time, send out green smell good, promote the formation of the aroma of a kind of tea steps.
