Abstract: using microwave vacuum drying method and drying Green Tea, different microwave drying equipment, vacuum and load capacity under the condition of drying curve and drying rate curves, the drying characteristics, drying process Green Tea mathematical model is studied.
Research shows that: with the increase of microwave power, drying rate Green Tea tea is also increasing. The vacuum degree is higher, the greater the drying rate. The less load, the greater the drying rate. The drying process is mainly divided into two stages of acceleration and deceleration, no obvious stage of constant rate of drying. Quantifying various factors on the drying rate, establishes the page mathematical model, provide a theoretical basis for the production of Green Tea.
