Problems solved by technology

Although the application of this technology is relatively common, generally speaking, there are still certain differences between the e-cigarette liquid (e-liquid) prepared by the prior art method and the traditional cigarette in terms of smoking taste and smoking quality. There is still room for further improvement in the preparation method of e-liquid (e-liquid)

Embodiment 1

[0041] In this example, taking B011 flue-cured tobacco leaves in Xuchang, Henan as an example, electronic cigarette oil was specifically prepared, and the specific process is briefly described as follows.

[0042] (1) Microwave cracking

[0043] Shred the flue-cured tobacco leaves of Xuchang, Henan Province B011, and place them in a constant temperature and humidity box to balance for 24 hours, so that the moisture content reaches 12%-14%. Take 100g of shredded tobacco and place it in a quartz reaction bottle, and place the quartz reaction bottle in the cracking furnace chamber In the center, microwave cracking is carried out; for specific cracking, the power of microwave cracking is 900W, and the cracking time is 120s.

[0044] (2) Extraction

[0045] The pyrolysis product produced after microwave pyrolysis in step (1) was extracted with 200 mL of absolute ethanol, and the ultrasonic extraction power was 40%. After the extraction was completed for 30 minutes, it was concentr...

Embodiment 2~3

[0067] In Example 2 and Example 3, taking C076 flue-cured tobacco leaves of Henan Xuchang and Hubei Enshi B1F tobacco leaves of Burley tobacco as examples, e-liquid and e-liquid were prepared, and the specific preparation process was the same as that of Example 1.

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

[0069] Table 2 Comparison results of the main aroma components of cut tobacco pyrolysis products after molecular distillation and without molecular distillation

[0070] .

[0071] It can be seen from the above table that after further molecular distillation of the pyrolysis products of shredded tobacco, the content of important tobacco aroma components in e-liquid is significantly higher than that in e-liquid without molecular distillation (due to nicotine and cigarette strength related, and its content is far greater than the content of other aroma substances, so it is exclu...

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...
