It contains a variety of volatile and semi-volatile aroma components, which have a significant impact on the sensory quality and style characteristics of cigarettes.

[0003] Currently, most tobacco pure oils are prepared by extraction using ethanol as a solvent. In the process of extracting tobacco fragments or cigarette dust with ethanol, the tobacco wax components on the surface of the tobacco leaves will inevitably be extracted into the ethanol extract. Only part of the tobacco wax components in the ethanol extract can be removed by filtration or centrifugation. A small amount of tobacco wax components will still be mixed into the tobacco pure oil. When the tobacco pure oil is applied to the atomizing liquid of an aerosol generating device, oily suspended matter is likely to appear, the atomizing liquid has poor solubility, and as the number of puffs increases, the ceramic core of the aerosol generating device is likely to suffer from serious carbon deposition or even core sticking, affecting the puffing experience of the aerosol generating device.

In the present application, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state; while "inside" and "outside" refer to the outline of the device.

[0023] In the related art, tobacco pure oil contains tobacco wax components. When tobacco pure oil is used in the atomizing liquid of an aerosol generating device, it is easy to cause the atomizing liquid to be poorly dissolved and the ceramic core of the aerosol generating device to be seriously carbonized or even sticky, which needs to be further improved.

[0024] To solve the above problems, the present invention provides a method for removing tobacco wax components from tobacco oil, comprising the following steps:

[0027] S3, allowing the mixed solution to settle to separate the tobacco wax components and the beeswax wax components, and filtering to obtain a tobacco oil alcohol solution from which the tobacco wax components have been removed.

[0028] In this embodiment, beeswax is added to the alcohol solution of tobacco oil, heated and stirred, so that tobacco wax components and beeswax are dissolved in the alcohol solution of tobacco oil to obtain a mixed solution, the mixed solution is allowed to settle to precipitate tobacco wax components and beeswax wax components, and the precipitated tobacco wax components and beeswax wax components are removed by filtering to obtain a tobacco oil alcohol solution with tobacco wax components removed. On the one hand, the beeswax wax component can absorb tobacco wax components when precipitating and then carry tobacco wax components to precipitate at the same time, the precipitated beeswax wax components can be in the form of flakes or feathers in the alcohol solution, the beeswax wax component particles are large and easy to filter, and when filtering the beeswax wax component, the tobacco wax components adsorbed on the beeswax wax components can be filtered and removed together, thereby removing the tobacco wax components in the tobacco oil; on the other hand, the mass ratio of beeswax to tobacco oil is (0.5-1):1, which can further ensure the removal effect of tobacco wax components in tobacco oil and reduce the residue of tobacco wax components in the tobacco oil alcohol solution.

In this embodiment, the temperature and time of the static sedimentation are set within the above range, which can reduce the solubility of the tobacco wax component and the beeswax wax component at a lower temperature, making it easier to precipitate from the mixed solution. In addition, the static sedimentation can provide enough time for the tobacco wax component and the beeswax wax component to slowly precipitate from the mixed solution, thereby improving the removal effect of the tobacco wax component and the beeswax wax component. Optionally, the temperature of the static sedimentation can be any one of 0°C, 1°C, 2°C, 3°C, 4°C, etc., or a range between any two of them; the time of the static sedimentation can be any one of 12h, 14h, 17h, 20h, 24h, etc., or a range between any two of them.

[0034] In one embodiment, in step S3, the filtration is performed by membrane separation filtration, and the membrane separation filtration uses a filter cloth with a mesh size of 1000 to 1500. Optionally, the mesh size of the filter cloth used for the membrane separation filtration can be any one of 1000 mesh, 1100 mesh, 1200 mesh, 1300 mesh, 1400 mesh, 1500 mesh, etc., or a range between any two of them.

[0104]

[0105]

[0106] Based on the test results of the above-mentioned Examples 1 to 6 and Comparative Examples 1 to 7, it can be seen that the tobacco clean oil alcohol solutions prepared in Examples 1 to 6 are all clear and transparent liquids with good aroma, sweetness and comfort; in addition, when the atomized liquid containing the tobacco clean oil alcohol solutions prepared in Examples 1 to 6 is used in an aerosol generating device, the problem of ceramic core sticking can be improved, and the user's smoking experience can be improved. Description: In this application, beeswax is added to the alcohol solution of tobacco clean oil, and the mass ratio of beeswax to tobacco clean oil is set to (0.5-1):1, which can ensure the removal effect of tobacco wax components in tobacco clean oil, reduce the residue of tobacco wax components in tobacco clean oil alcohol solution, and tobacco clean oil alcohol solution is not easy to have oily suspended matter.
