Production method for extracting absolute oil of tobacco leaves

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...

AI Technical Summary

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 extraction method of tobacco leaf absolute disclosed in the patent document 200810186049.5 overcomes the shortcomings of conventional solvent extraction methods, 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.
