摘要

设计并研制了一种用于草本油脂蒸馏的冷凝器。采用两种常用制冷剂R12和R134a从蒸汽-空气混合流中分离薄荷叶的水和精油分子，对冷凝器的性能进行了评价。在实验中，汽-气混合流动选择了三个风速水平(1、2和3 m/s)和温度水平(180、210和250 ℃)。对于这种冷凝器，R12的性能优于R134a制冷剂。在较低的风速和较低的温度条件下，对留兰叶精油的提取效果最好。

Distillation of herbaceous oils in the presence of non-condensable gases

A condenser was designed and developed for distillation of herbaceous oils. The performance of the condenser was evaluated by using two common refrigerants namely R12 and R134a to separate the water and essential oil molecules of spearmint (Mentha spicata) leaves from a vapor-air mixture flow. Three levels of air speed (1, 2 and 3 m/s) and temperature (180, 210 and 250 °C) were selected for the vapor-air mixture flow during the experiments. For this condenser, a better performance was observed for the R12 than the R134a refrigerant. The best performance of the condenser was obtained at lower air speeds and lower temperatures for the essential oil of spearmint leaves.
