小型医用蒸馏回收提取锅的研制及其应用

The development of small medical distillation and recycling pot and its application

目的：研制一种金属制的小型医用蒸馏回收提取锅,以作为1--10 kg药材量的挥发油提取及较低沸点的有机溶媒的回收,并考察其提取挥发油及乙醇回收的效果。方法：自制包括加热、冷凝及收集部分的小型医用提取锅,并考察其提取效果：1将该提取锅分别在直火加热、水蒸汽蒸馏状态下同玻璃提取仪器进行挥发油的提取对照实验;2将该提取锅同玻璃蒸馏器分别用于50%乙醇的回收对照实验。结果：1分别使用研制的蒸馏回收提取锅及玻璃蒸馏器,无论用水蒸汽蒸馏或直火加热提取挥发油时所提取的挥发油数量基本相同,差异无统计学意义;2分别用研制的蒸馏回收提取锅及玻璃蒸馏器进行乙醇回收时,所回收的乙醇量基本相同,差异无统计学意义。结论：小型医用蒸馏回收提取锅可作为1--10 kg药材量的挥发油提取或较低沸点的有机溶媒回收提取用,值得推广。

Objective：To develope a kind of small medical distillation and recycling pot for 1~10kg amount of herbs to extract volatile oil and recycle the organic solvents with low boiling point, and examined effect of volatile oil extraction and ethanol recovery effect.Methods： We made a small medical distillation and recycling pot heating, including extraction condensing and collecting part. We examined the following extraction： （1）The small medical distillation and recycling pot and glass extraction apparatus were used to extract volatile oil respectively in a direct fire heating and steam distillation in the control experiments; （2）The small medical distillation and recycling pot and glass extraction apparatus were used to recycle 50% ethanol in the control experiments.Results： （1）In the volatile oil extraction experiments whether direct fire heating or steam distillation, the small medical distillation and recycling pot could extract the essential oil as many as the glass distillation, with no statistical differences. （2）the small medical distillation and recycling pot could recycle ethanol as many as the glass distillation, also with no statistical differences. Conclusion： The small medical distillation and recycling pot could be used for 1-10kg amount of herbs to extract volatile oil and recycle the organic solvents with low boiling point, and worthy recommending.
