Example Embodiment

[0040] Example 1

[0041] This embodiment takes B011 flue-cured tobacco leaves in Xuchang, Henan Province as an example, and specifically prepares electronic cigarette oil. The specific process is as follows.

[0042] (1) Microwave cracking

[0043] After cutting Henan Xuchang B011 flue-cured tobacco leaves into shreds, place them in a constant temperature and humidity box for 24 hours to equilibrate to make the moisture reach 12%-14%. Take 100g of shredded tobacco and place them in the quartz reaction flask, and place the quartz reaction flask in the cracking furnace cavity In the center, microwave cracking is carried out; for specific cracking, the microwave cracking power is 900W and the cracking is 120s.

[0044] (2) Extraction

[0045] The cracked product produced after microwave cracking in step (1) was extracted with 200 mL of absolute ethanol, the ultrasonic extraction power was 40%, and after 30 minutes of extraction, it was concentrated under reduced pressure to no liquid dri...

Example Embodiment

[0066] Examples 2~3

[0067] Example 2 and Example 3 respectively took Henan Xuchang C076 flue-cured tobacco leaf and Burley Hubei Enshi B1F tobacco leaf as examples, specifically prepared e-liquid and e-liquid, and the specific preparation process was the same as in Example 1.

[0068] The content changes of some components in the e-liquid prepared in the foregoing Examples 1 to 3 are summarized as shown in Table 2 below.

[0069] Table 2 Comparison of main aroma components of cut tobacco cracked products after molecular distillation and those without molecular distillation

[0070] .

[0071] It can be seen from the above table that after the pyrolysis product of cut tobacco is further subjected to molecular distillation, the important tobacco flavor components in the e-cigarette oil are significantly higher than the important tobacco flavor components in the e-cigarette oil obtained without molecular distillation (due to nicotine and cigarette strength Related, and its content is f...

Abstract

The invention belongs to the technical field of electronic cigarette, and particularly relates to a preparation method of electronic tobacco tar. The preparation method of the electronic tobacco tar comprises the steps of microwave pyrolysis, extraction, molecular distillation to obtain light components and heavy components and the like. Due to the fact that firstly pyrolysis operation is carried out, compared with a general preparation method, tar and other harmful substances can be effectively reduced when molecular distillation is carried out later; and on the other hand, the light components and the heavy components are obtained through molecular distillation treatment, after electronic cigarette liquid is prepared further, the quality of electronic cigarette fragrance can be effectively improved, so that the electronic cigarette fragrance is grace and fine, traditional cigarette characteristic fragrance is achieved, strength, satisfaction and sensory quality are improved, and thus better practical value is achieved.

Description

technical field [0001] This application belongs to the technical field of electronic cigarettes, and specifically relates to a patent application for a method for preparing electronic cigarette oil. Background technique [0002] Generally speaking, new tobacco products mainly include new cigarettes, electronic cigarettes and smokeless tobacco, among which new cigarettes are mainly heat-not-burn cigarettes, and smokeless tobacco products mainly include snus and chewing tobacco. Due to the characteristics of less harmfulness, higher safety, and the ability to properly eliminate the hazards of second-hand smoke, and especially the convenience of smoking, new tobacco products have achieved relatively rapid development in recent years. [0003] Compared with existing traditional cigarettes, e-cigarettes in new tobacco products can more vividly simulate the smoking process and better meet the physiological, psychological and behavioral needs of smokers. Therefore, they are conside...
