A kind of flue-cured tobacco extract and electronic cigarette liquid

Abstract

The invention discloses flue-cured tobacco extract and electronic cigarette liquid. Tobacco leaves, tobacco shreds, tobacco powder and / or tobacco ash of flue-cured tobacco serve as raw materials for the flue-cured tobacco extract, and extract solvent is added into a Soxhlet extractor so that Soxhlet extraction can be conducted on the raw materials; as an improvement, a vacuum pump is connected to a condensation pipe of the Soxhlet extractor so that the vacuum degree in the Soxhlet extractor can be kept within the range of 20 mmHg to 80 mmHg; the temperature of condensate in the condensation pipe is 5 DEG C below zero or lower; after Soxhlet extraction is completed, the condensate is collected and concentrated into the flue-cured tobacco extract. A whole Soxhlet extraction system is in a negative pressure state, the boiling point of the extract solvent is reduced, the extraction temperature is reduced, the solvent circulation in the extraction process is accelerated, the extraction frequency is increased, and efficiency is higher. Meanwhile, the solvent heating temperature is lower, and therefore the extraction condition is more moderate, the excessive chemical reaction, caused by solvent high-temperature heating, between aroma components in the extract is avoided, and the extract contains less offensive odor.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, in particular to a flue-cured tobacco extract and electronic cigarette liquid. Background technique [0002] As a new type of tobacco product, electronic cigarette liquid determines the sensory style characteristics of electronic cigarette, so the preparation of electronic cigarette liquid becomes the key to electronic cigarette products. The basic technical principle of the electronic cigarette is that when smoking the electronic cigarette, the battery of the electronic cigarette supplies power to the atomizer of the electronic cigarette, the atomizer starts to work, and atomizes the liquid stored in the electronic cigarette to generate smoke. The smoke liquid in electronic cigarettes, also known as "smoke oil", is stored in absorbent materials, commonly known as "adsorbent cotton". The liquid in the e-cigarette is actually a formula essence, which is atomized into "smoke" when sm...

AI Technical Summary

Problems solved by technology

This traditional method, 1. The extraction efficiency is not high, because a certain solvent is easy to reach saturation, and the required aroma components can no longer be extracted from the tobacco; 2. In order to improve the extraction efficiency, it will be heated until reflux, and the temperature will rise to the solvent. The boiling point will also bring unnecessary miscellaneous gases to the extracted product; 3. It needs to be filtered after extraction, especially for the filtration after soot extraction, which is very time-consuming

[0004] At present, a common problem with e-cigarette products is that e-cigarette liquids lack or have weak tobacco flavor characteristics, and some are even closer to food such as chewing gum. There is a large deviation in style from smoking cigarettes, and the overall style is close to food
