The lower end of the stirrer 22 extends to the bottom of the distillation still 1 through the stirring mounting port 126 to stir the medicine in the distillation still 1. In order to improve the stirring effect of the stirrer 22, the stirrer 22 has two layers of stirring centers, a cross-shaped stirring blade is arranged at the lower end of the stirrer 22, and a push-type stirring blade is arranged in the middle section.
The distillation head 4 is provided with a vertical section 41 and an inclined section 42, and the inclined section 42 is inclined downwards. The inclined upper end is communicated with the inner side of the upper part of the vertical section, the inclined lower end is connected with the distillation opening 123, and two ends of the vertical section 41 are respectively connected with the lower end of the vertically installed condensation pipe 5 and the upper end of the connecting bent pipe 6. The upper end of the condensation pipe 5 is connected with a vacuum extractor (not shown in the figure), and the lower end of the connecting elbow 6 is connected with a collecting bottle 8. A valve 7 is arranged on the connecting elbow 6. The valve 7 is closed, so that the lower part of the vertical section 42 can become a temporary storage separation area, condensed substances can overflow, the condensed substances flow back to the distillation still 1 along the inclined section 41, and standing layering is realized in the storage separation area. In prior art devices, the condensed liquid material drips or slides along the wall of the distillation head at the junction of the distillation head and the condenser tube.

The stirring mechanism 2 is started and heated through the interlayer of the tank body 11. The effective components in the medicine bottle are heated to shift gas phase from liquid phase and enter the condensation pipe 5 along the distillation head 4, and the gas phase substance is changed into liquid phase again when meeting cold and falls into the vertical section of the distillation head 4. Because the valve 7 blocks the passage between the distillation head 4 and the collecting bottle 8, the condensed medicine can only flow back into the distillation kettle 1 for distillation again, so that manual transfer is not needed. On the other hand, during sampling analysis, a proper amount of medicine is put into the liquid collecting bottle 8, then the valve 7 is closed, the vacuum pumping port 81 is opened, the sample can be taken out for analysis after the normal pressure is recovered, after sampling is completed, the liquid collecting bottle 8 is vacuumized again, and fraction collection operation can be continued by opening the valve 8. Due to the arrangement of the valve 7, the vacuum distillation operation is not influenced in the sampling analysis process, and the vacuumizing treatment is not required to be repeated. Moreover, the device is made of transparent glass, so that the device can be fully utilized to observe the state of the medicine. For some medicine components which can be separated, the length of the vertical section 42 of the distillation head 4 can be properly increased, so that the lower part of the vertical section is a storage separation area, and the liquid at the lowest layer in the vertical section 42 is discharged by intermittently opening the valve 7, so that the medicine layers are separated, and the distillation and classification operation is realized.
