摘要
The mass transfer model describing the separation of essential oils from plant materials has been proposed and the mass transfer coefficient has been obtained by fitting the present model to the experimental data for three kinds of plant materials. The validity of the model has been verified. To im' prove the vapor-solid contact, a mechanical agitator has been installed in the steam distillator. The effect of agitating rate on mass transfer coefficient has also been examined.
建立水蒸气蒸馏分离植物挥发油传质过程数学模型．对常规蒸馏器进行改进，加入搅拌装置强化了传质．通过３种植物蒸馏的实验数据，求取了总传质系数值并验证了数学模型，并讨论了搅拌转速对传质系数的影响．
