采用微波真空干燥方式干燥绿茶，绘制了不同微波功率、真空度、装载量条件下的干燥曲线、干燥速率曲线，对干燥过程中绿茶干燥特性、数学模型进行了研究。研究表明：随着微波功率的增大，绿茶茶叶的干燥速率也在增大。真空度越高，干燥速率越大。装载量越少，干燥速率越大。干燥过程主要分为加速、降速两阶段，无明显恒速干燥阶段。量化各因素对干燥速率的影响，建立了page数学模型，为绿茶生产提供理论依据。
採用微波真空榦燥方式榦燥綠茶，繪製瞭不同微波功率、真空度、裝載量條件下的榦燥麯線、榦燥速率麯線，對榦燥過程中綠茶榦燥特性、數學模型進行瞭研究。研究錶明：隨著微波功率的增大，綠茶茶葉的榦燥速率也在增大。真空度越高，榦燥速率越大。裝載量越少，榦燥速率越大。榦燥過程主要分為加速、降速兩階段，無明顯恆速榦燥階段。量化各因素對榦燥速率的影響，建立瞭page數學模型，為綠茶生產提供理論依據。

In this paper ,the green tea was dried by microwave vacuum ,and the drying characteristics and mathematical model in different microwave power ,vacuum ,loading conditions was draw .Studies show that :With the microwave power increasing ,the water loss rate of green tea also increased .Increasing the vacuum ,the water loss rate increased .When reducing the loading ,the water loss rate increased .It could be divided into acceleration and deceleration two phases in drying process ,and did not have significant con-stant drying phase .Quantifying various factors on the drying rate ,and the mathematical model was estab-lished ,it can provide a theoretical basis for the production of green tea .
