摘要: 在往复槽锅龙井茶炒制机加工过程中,茶叶水分变化由恒率失水和降率失水组成。往复槽锅为一典型的对心曲柄滑块机构,写出了位移S、速度V和加速度a与时间t的运动方程。将茶叶视为质点,计算出茶叶的受力的大小。茶叶在槽锅内受往复撞击力被理直、受压棒滚压而成扁平形状。

Abstract: During the period of processing of longjing tea in the Reciprocation-trough type machine, the change of moisture content possessed an equal rate and a reducing rate. Because the trough movement is a standard crank mechanism, the movement equation on the displacement(s), speed(v), acceleration(a) and time(t) was established. Regarding the tea leaf as particle, the size of receiving force of tea leaf could be calculated. The tea leaves formed straight shape under the acting of strike force in reciprocation tough and formed flat shape under the pressing of weight pole.

Key words: Longjing tea, Reciprocation trough, Shaping
