The tea deactivation drying equipment uses the principle of microwave heating. During the heating process, the tea is heated, dehydrated, softened, volatilized grass odor, purified enzyme activity, and the appearance is green. 

Compared with the traditional tea fixation and drying methods, the equipment has the following advantages : reasonable design, compact structure, reliable performance, simple operation and convenient maintenance. 

1.Heating speed : Microwave directly heats the inside and outside of the tea at the same time. It can be processed without preheating. In traditional production, there needs to be a preheating process. 

2.Homogeneous heating : Microwave deactivation drying is to irradiate the tea evenly through the electromagnetic wave generated by the magnetron, and heat the inside and outside at the same time, without focal leaves, focal edges, debris, etc., while the traditional tea deactivation is conducted to the tea through the heating drum and the heat is not uniform, which is easy to produce external cooked endogenous, external dry and internal wet. It has burnt taste, burnt leaves and debris, which seriously affects the quality of tea. 

3.Less nutrient loss of tea : The tea leaves stay in the microwave heating box for a short time, and do not need air and steam heat conduction, so it can retain the nutrients in the tea to a large extent. Durable traditional de-enzyming and drying have a long retention time in the roll-to-roll de-enzyming machine and dryer, so the nutrients in the tea are lost more. 

4 、 Sterilization, alcoholization effect : tea in the picking, production process, often have the possibility of secondary pollution, microwave fixation, drying with sterilization, alcoholization function and the traditional process equipment does not have this function, microwave, especially for summer, autumn tea, in addition to the bitter taste, quite effective, this alcoholization function, other machinery is unable to generation. 

5 、 Reduce labor intensity, improve work efficiency : This equipment adopts automatic feeding and unloading, the operator only need to press the button, monitoring equipment running equipment and inspection of the degree of de-enzyming of fresh leaves, the whole de-enzyming, drying only need 1-2 people.
