Example Embodiment
[0027] Example 1
[0028] The present invention also provides a method for extracting nicotine using a complete set of short-path distiller equipment, including the following steps:
[0029] S1. The crude nicotine organic solution is pumped by the feed pump 14 to the feed port 15, and then enters the distillation tank 2 for the short-path distillation separation process. The feed temperature of the short-path distiller is 62 ℃, and the heating jacket is used 3 Heat the distillation tank 2 to 63°C, use the vacuum pump 5 to vacuum the distillation tank 2 and control the pressure at 12Pa; in order to improve the extraction rate of refined nicotine products, the distillation tank 2 is lightly assembled The ratio of the sub-to-heavy component is controlled to 2 / 3, and the speed of the film wiper 18 is controlled at 180r / min.
[0030] S2. The final light component refined nicotine product is discharged from the light component outlet 7 into the collection tank 6 for storage.
