Tea processing is a traditional industry in China. In order to improve the processing quality and industrial modernization of tea, it is necessary to apply new science and technology in tea primary processing industry and deep processing industry, and advanced microwave technology has a good application prospect in tea. Microwave refers to the ultra-high electromagnetic wave between the radio and the light wave at 3OMHz-300000MHz. Currently, microwave devices used in the food industry have a center wavelength of 0.328 m (frequency 915 MHz) or 0.1225 m (frequency 2450 MHz).
General hot air drying process, material external heated, surface drying, heat transfer inwards, the direction and water diffusion direction in the opposite direction, affect the moisture to evaporate.But microwave's an internal heating, The part of high water content heat up faster.So in the microwave drying process, water migration speed from the inner to the outer is high, drying speed is significantly faster than hot air drying.

Application of microwave drying in the drying tea has the following advantages:
1) Fast drying speed ;
2) High products quality, because tea surface temperature is not too high, less chlorophyll changes, colour and lustre is green emerald green, less aroma loss;
3) Uniform drying;
Due to the fast evaporation speed, easy to form porous, good water complex content easy to dissolution when making tea.
