Problems solved by technology

A supercritical extraction method is disclosed in the patent document 02133758.6, which mainly uses liquid carbon dioxide as a solvent. The extracted net oil is of good quality and high oil yield, but the operation is complicated, and it is difficult for producers to generally master it, and the production cost is very high. It is more suitable to extract a small amount of high-grade absolute oil. If it is used to produce tobacco leaf absolute oil, the first is that the production capacity is too low, but the cost is too high
In addition, the laboratory microwave-assisted extraction method of tobacco leaf absolute disclosed in patent document 200810186049.5 overcomes the disadvantages of the conventional solvent extraction method, such as large solvent loss and high operational risk, and also overcomes the supercritical extraction method. It is complex and the production cost is lower than that of supercritical extraction, but it is only a laboratory research method and has not been produced yet. Moreover, it is extracted with a mixed organic solvent, and the solvent is difficult to reuse. The waste is large and the cost is naturally high.

[0021] Example 1: Take 300 kilograms of tobacco leaves, dry them to a moisture content of 11wt%, crush them to a particle size of less than 5mm, put them into a 4-ton straight-cylinder extraction tank with an ultrasonic generator, add 3000 liters of petroleum ether, soak for 40 minutes, start Ultrasonic leaching with an ultrasonic generator for 20 minutes to release the extract; then add 1,800 liters of petroleum ether, start the ultrasonic leaching with the ultrasonic generator for 10 minutes, and release the extract; combine the two extracts, concentrate under vacuum, and start to control the temperature at 40 ℃, the vacuum degree is 0.06mpa, when the solvent is recovered, the temperature is increased to 55℃, the vacuum degree is 0.08mpa, and then concentrated for about 20 minutes to obtain 2.74 kg of extract with a specific gravity of 1.19; add 15 liters of 95% to the extract while stirring Continue to stir for 30 minutes, let it stand for 8 hours, and filter. Add 3% of the w...

Abstract

The invention relates to a production method for extracting tobacco leaf clean oil. The production method includes: taking tobacco leaves and / or waste defective tobacco powder as raw materials; disposing the raw materials in an extracting device of an ultrasonic generator after drying and smashing; using fat-soluble organic solvent for extraction, using water-soluble organic solvent for dissolving, and obtaining needed tobacco leaf clean oil through filtering and depressurizing and compressing of filtrate. A principle that ultrasonic waves are high in penetrability in liquid medium is utilized, so that the solvent can quickly immerse the tobacco leaves and break cells at normal temperature and within short time to enable tobacco oil to be extracted by the solvent as soon as possible. Extraction is completed at the normal temperature and within the short time, solvent consumption is low, and oil yield is high, so that energy consumption is lowered remarkably, yield is increased, production cost is lowered greatly, and operating dangerousness is lowered relatively.

Description

Technical field [0001] The invention relates to a production method for extracting absolute tobacco oil, belonging to the technical field of chemical preparation. Background technique [0002] Tobacco leaf absolute is widely used in people's daily life. In the tobacco industry, tobacco leaf absolute is a frequently used additive or used as an indispensable ingredient in smoking cessation products. In addition, due to its special fragrance and certain physiological activity, many chemical products often use it as an additive for fragrance adjustment or antibacterial and insecticide. In recent years, as the substitute of cigarettes, e-cigarettes continue to be accepted by more and more smoking enthusiasts, as the atomization liquid of e-cigarettes, there are also essential tobacco leaf absolutes. As the amount of e-cigarettes increases, With the increasing coming, there are also tobacco leaf absolutes of uneven quality, and there are even products that use tobacco leaf extract t...
