Embodiment 1

[0021] Get 10 parts of tobacco raw material, after soaking for 0.5 hours, loosen the fiber slurry with a beating degree of 20 ° SR with pulping equipment; dilute the slurry with deionized water to a concentration of 1.2% by weight, and make a sheet base with papermaking equipment; Take 5 parts of rosemary, put them in the extraction device, under the conditions of extraction pressure 28MPa, extraction temperature 50°C, analysis pressure 7.0MPa, analysis temperature 60°C, CO 2 Under the condition of a flow rate of 25kg / h, the supercritical extract was obtained after constant temperature and pressure extraction for 3 hours; the supercritical extract was taken and placed in a molecular distillation equipment. Under the conditions of rotation / min and flow rate of 2mL / min, the residue was obtained; the residue was heated to 150°C, placed in a molecular distillation equipment, at a vacuum of 5Pa, the heating temperature was 350°C, and the rotor scraping speed was 280 rpm , flow rate...

Embodiment 2

[0024] Get 20 parts of tobacco raw material, after soaking for 2 hours, loosen the fiber slurry with beating degree of 40°SR with pulping equipment; dilute the slurry with deionized water to a concentration of 0.5% by weight, and make a sheet base with papermaking equipment; Take 1 portion of citronella grass, put it in the extraction device, and extract it at an extraction pressure of 25MPa, an extraction temperature of 40°C, an analysis pressure of 5.5MPa, an analysis temperature of 60°C, and CO 2 Under the condition of a flow rate of 25kg / h, the supercritical extract was obtained after constant temperature and constant pressure extraction for 3 hours; the supercritical extract was taken and placed in a molecular distillation equipment. Under the conditions of rotation / min and flow rate of 2.4mL / min, the residue was obtained; the residue was heated to 180°C, placed in molecular distillation equipment, and the vacuum degree was 10Pa, the heating temperature was 400°C, and the ...

Embodiment 3

[0027] Repeat Example 1, with the following differences: the weight percent concentration of the slurry is 1.0%, and the natural spice plant is basil; Dry to obtain the low-temperature tobacco material 3.

[0028] After the medium-temperature tobacco material 3 prepared by this method was added to non-combustible cigarettes, compared with the blank control, the aroma was fuller, the feeling of moistening was better, and the irritation was reduced after sensory evaluation.

Abstract

The invention discloses a method for preparing medium-temperature tobacco material used for a non-combustion cigarette. Mashing is directly carried out on tobacco raw material to prepare a substrate, aroma components are extracted from natural fragrant plant flowers through a supercritical CO2 fluid extraction-molecule distillation method, and then the substrate is coated with the aroma components to obtain the needed medium-temperature tobacco material. According to the method, the aroma components contained in the tobacco raw material self are kept to the maximum, and the selectivity of the supercritical CO2 fluid extraction-molecule distillation method is used for achieving directed extraction of chemical constituents of which the boiling point is from 300 DEG C to 400 DEG C in the natural fragrant plants, so that regulating and controlling of the chemical constituents of the medium-temperature tobacco material are achieved. The prepared medium-temperature tobacco material is rich in aroma, harmonious in smoke, good in sense organ comfort, obvious in sweet feeling and prominent in faint scent characteristic.

Description

technical field [0001] The invention belongs to the technical field of combustion-free cigarettes, and in particular relates to a preparation method of a medium-temperature tobacco material used in combustion-free cigarettes. Background technique [0002] The development of new non-combustible cigarettes is the focus and hotspot of tobacco industry research at the present stage. Although many achievements have been made in related research, the research on the directional release of aromatizing substances at a specific temperature is still blank. For traditional cigarettes, because they are burned at about 800°C, a large amount of tar and various aroma components are produced, and some components produced by combustion are harmful to the health of smokers. Therefore, it is of great practical significance for the development of cigarettes to develop tobacco materials that can release smoke similar to normal smoking cigarettes through dry distillation at a lower temperature. ...
