Problems solved by technology

In the patent document 02133758.6, a supercritical extraction method is disclosed, which mainly uses liquid carbon dioxide as a solvent. The quality of the extracted net oil is good and the oil yield is high, but the operation is complicated, and it is difficult for producers to generally master it. 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, firstly, the production capacity is too low, but the cost is too high
In addition, the laboratory microwave-assisted

Example Embodiment

[0018] 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 tons 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 1800 liters of petroleum ether and start the ultrasonic leaching with the ultrasonic generator for 10 minutes to 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, filter, and concentrate th...

Abstract

The invention relates to a production method for extracting the absolute oil of tobacco leaves, which comprises the following steps of: taking the tobacco leaves and/or waste tobacco dust as raw materials, drying, crushing, and putting the crushed raw materials into an extraction device with an ultrasonic generator; and extracting by using fat soluble organic solvent, dissolving by using water soluble organic solvent, filtering, and concentrating filter liquor under reduced pressure to obtain the required absolute oil of the tobacco leaves. In the method, the tobacco leaves can be infiltratedquickly by the solvent and oil cells can be ruptured by utilizing the principle of high penetrating power of ultrasonic waves in a liquid medium at normal temperature within a short time, so that tobacco tar is leached by the solvent as soon as possible. Due to short-time extraction at the normal temperature, less using amount of solvent and high oil yield, energy consumption is reduced obviously, the production capacity is improved, the production cost is reduced greatly, and the danger of operation is reduced relatively.

Description

technical field [0001] The invention relates to a production method for extracting tobacco leaf absolute, 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 an additive ingredient that is often used, or used as an indispensable ingredient for smoking cessation products. In addition, due to its special fragrance and certain physiological activity, many chemical products often use it as an additive for flavoring or antibacterial and insecticidal. In recent years, as electronic cigarettes, which are substitutes for cigarettes, have been accepted by more and more smoking enthusiasts, there is also essential tobacco leaf absolute in the atomization liquid of electronic cigarettes. At the same time, there are tobacco leaf absolutes of varying quality, and there are even products filled with tobacco leaf extracts, resulting in unstable...
