[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.

[0031] The preparation method of crude nicotine organic solution in S1 includes the following steps:

[0032] S3. Crush the tobacco leftovers to a particle size of 2mm for later use, and dilute the concentrated sulfuric acid to 13% H 2 SO 4 Solution for use;

[0033] S4. Add petroleum ether extract to the powdered tobacco leftovers obtained in S1 for extraction, wherein the mixing ratio of petroleum ether and the leftovers is 12mL/1g, the extraction time is 1h, and the extraction temperature is 40℃;

[0034] S5. Add 13% H obtained in S1 to the extract obtained in S2 2 SO 4 The solution is acidified, and after the acidification, the resulting mixed solution is filtered under reduced pressure to obtain a filtrate containing nicotine organic matter;

[0035] S6. Add 13% H obtained in S1 to the extract obtained in S2 2 SO 4 The solution is acidified, and after the acidification is completed, the resulting mixed solution is suction filtered to obtain a filtrate containing nicotine organic matter;

[0036] S7. The filtrate containing the nicotine organics obtained in S4 is subjected to vacuum distillation and concentration, and finally a crude nicotine organic solution with a nicotine content of 15% by mass is obtained.
