Embodiment 1

[0028] The present invention also provides a method for extracting nicotine by utilizing a complete set of short-path distillers, comprising the following steps:

[0029] S1. Pump the crude nicotine organic solution from the feed pump 14 to the feed port 15, and then enter the distillation tank 2 for short-path distillation and separation process, wherein the feed temperature of the short-path still is 62°C, and the heating mantle is used to 3. Heat the inside of the distillation tank 2 to 63°C, use the vacuum pump 5 to vacuumize the distillation tank 2, and control the pressure at 12Pa; The ratio of component to heavy component is controlled to be 2 / 3, and the rotating speed of film wiper 18 is controlled at 180r / min simultaneously.

[0030] S2. The final light component refined nicotine product is discharged into the collection tank 6 from the light component outlet 7 for storage.

[0031] The method for preparing the crude nicotine organic solution in S1 comprises the foll...

Abstract

The invention relates to the technical field of nicotine extraction and in particular relates to a device and a method for extracting nicotine by using complete equipment of a short-range distiller. The device comprises a bottom plate, wherein a support rack is fixed on the bottom plate; a distillation tank body is mounted on the support rack; the outer side of the distillation tank body is wrapped with a heating jacket; a motor is connected with the top end of the distillation tank body through a fixing sleeve; the output shaft of the motor is connected with a rotating shaft; a distributor is connected with the upper end of the rotating shaft; membrane scrapers are connected with two sides of the rotating shaft; a condensation circulation pipeline is arranged in the middle inside the distillation tank body; a condenser is connected with the lower end of the condensation circulation pipeline; a feeding hole is formed in one side of the upper end of the distillation tank body; a feeding pump is mounted on one side of the feeding hole; a heavy component outlet is formed in one side of the lower end of the distillation tank body; a light component outlet is formed in the bottom end of the distillation tank body; a vacuum interface is further formed in one side of the lower end of the distillation tank body; and a vacuum pump is connected with the vacuum interface. The invention further provides a method for extracting nicotine by using the complete equipment of the short-range distiller. By adopting the device and the method, the problems of low nicotine yield and purity are solved.

Description

technical field [0001] The invention relates to the technical field of nicotine extraction, in particular to a device and method for extracting nicotine by using a complete set of short-path distillers. Background technique [0002] Natural nicotine, also known as nicotine, is an important medicine, natural pesticide, spice, and chemical raw material. It can be used to produce safe and effective smoking cessation products, electronic cigarettes, and low-toxicity and no residue pesticides. Nicotine with a purity of more than 99.9% is in great demand, and the price at home and abroad is more than 1 million yuan / ton. At present, nicotine is mainly extracted from tobacco or tobacco sticks and tobacco leaves discarded from tobacco production. [0003] Existing nicotine extraction methods such as steam distillation, sulfuric acid stripping, supercritical fluid extraction and ion exchange focus on the extraction rate of nicotine, and mostly use simple distillation methods to refin...
