Continuous tea dryer, microwave tunnel tea dryer, dried tea sterilizer

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 microwaveis 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;

4. Due to the fast evaporation speed, easy to form porous, good water complex content easy to dissolution when making tea.
