At present, the application of dryers in tea production often has three modes of operation:

1, for killing
2, used for secondary killing and drying
3, for drying and sterilization
The second method is often used in the famous tea processing production line. For example, after the drum greening machine is finished and preliminary shape is formed, the microwave tea drying machine is used for the second killing and the first drying, the purpose is to make the tea fully and Reduce the moisture content to facilitate the next process.

The use of microwave to kill the green leaves, the color is green, and the uniformity is good. After the green leaves are placed for 1h, the color remains green and the overall quality is better than that of the conventional drum type. This is because the microwave is used for tea to kill, it can simultaneously heat the inside and outside of the bud, and the microwave penetration ability is strong. As long as the operation is strictly in accordance with the instructions of the machine, the production time is consistent with the leaf, which can be completely blunt. The enzyme activity in the fresh tea makes the green leaves green and green.

The sterilization function of the microwave tea greening machine in tea processing, using microwave drying equipment to dry tea, can inhibit the growth of harmful molds such as Aspergillus, Penicillium and Fusarium in tea, thereby reducing the mildew of tea.
