The tea processing is a traditional industry. In order to improve the processing quality of tea and modernize the industry, it is necessary to apply new science and technology in the primary and deep processing industries of tea, and advanced microwave technology has good application prospects in tea.

The application prospect microwave machine in tea processing.
1. Microwave tea fixation:
The production of green tea, oolong tea, health tea, etc. requires heating treatment to inactivate the activity of polyphenol oxidase, evaporate part of the water, volatilize the smell of green grass, and soften the tissue. At present, the frying method is commonly used in production, and a few places use the steam finishing method. The test results showed that the quality of tea leaves processed by microwave curing and frying was good, and there was no significant difference, but the microwave curing time was short (1/8 of the frying time) and could be carried out continuously.
2. Microwave tea drying:
During the general hot air drying process, the outside of the material is heated, the surface is dried, and the heat is transferred inward. Its direction is opposite to the direction of moisture diffusion and transfer, affecting the outward evaporation of moisture. The microwave is internal heating, and the parts with high water content will heat up faster. Therefore, in the process of microwave drying, the migration speed of moisture from the inner layer to the outer layer is fast, and the drying speed is obviously faster than that of hot air drying.

The application of microwave drying in tea drying has the following advantages:
(1) fast drying speed;
(2) good product quality;
Because the surface temperature of the tea is not too high, there are few changes in chlorophyll, the color is green and durable, there is less aroma loss, and the drying is uniform At the same time, due to the fast evaporation of water, it is easy to form porosity, the rehydration of the product is good, and the content is easy to dissolve when making tea.
