Burley tobacco extractive, electronic tobacco juice and tobacco extraction method

Abstract

The invention relates to burley tobacco extractive, electronic tobacco juice and a tobacco extraction method. The raw materials of the burley tobacco extractive are tobacco leaves, cut tobacco leaves, tobacco powder and / or tobacco ash of burley tobacco, and Soxhlet extraction is carried out on the raw materials by adding an extraction solvent in a Soxhlet extraction device. The tobacco extraction method is characterized in that a condensation pipe of the Soxhlet extraction device is connected with a vacuum pump, and the vacuum degree of the Soxhlet extraction device keeps at 20-80 mmHg; the temperature of condensate in the condensation pipe is below minus 5 DEG C; after Soxhlet extraction, an extraction solution is collected and concentrated to obtain the burley tobacco extractive. The whole Soxhlet extraction system is in a negative pressure state, the boiling point of the extraction solvent is lowered, the extraction temperature is lowered, circulation of the solvent is accelerated in the extraction process, the extraction frequency is improved, and efficiency is higher. As the heating temperature of the solvent is lower, the extraction conditions are milder, extreme chemical reaction among aroma components in the extractive caused by high-temperature heating of the solvent is avoided, and less impurity gas in the extractive is generated.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarettes, and in particular relates to a Burley tobacco extract, an electronic cigarette liquid and a method for extracting tobacco. 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 ess...

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
