Embodiment 1

[0020] The additive composed of glycerol and furanone at a ratio of 100:1 is prepared into an additive solution with a mass concentration of 25% by using ethanol-water with a volume ratio of 1:1 as a solvent, and sprays 92.3 per kilogram of tobacco leaves during the tobacco leaf feeding process. Add 1 gram of additive solution to the tobacco leaves, then make shredded tobacco according to the conventional shredding process, and roll it into cigarettes. The theoretical addition amount of additives in each cigarette is 15 mg (the amount of tobacco leaves in each cigarette is calculated on the basis of 0.65 g).

[0021] Control sample: Spray ethanol-water with a volume ratio of 1:1 on the tobacco leaves during the tobacco leaf feeding process, and then make shredded tobacco according to the conventional silk-making process, and roll it into cigarettes. The addition of ethanol-water to each cigarette The amount is the same as that used in the added sample.

Embodiment 2

[0024] The ratio of glycerol and furanone is 50:1, and the additive solution composed of glycerol and furanone is prepared into an additive solution with a mass concentration of 40% with pure ethanol, and the prepared additive solution is sprayed with 0.2 gram of additive solution per kilogram of tobacco shredded tobacco in the process of perfuming tobacco shreds. Tobacco, and rolled into cigarettes, the theoretical addition amount of additives in each cigarette is 0.05 mg (the amount of shredded tobacco in each cigarette is calculated as 0.63 g).

[0025] Control sample: ethanol was sprayed on the shredded tobacco during the process of flavoring the shredded tobacco, and rolled into cigarettes. The amount of ethanol added to each cigarette was the same as that used in the added sample.

Embodiment 3

[0028] The additive composed of glycerol and furanone at a ratio of 150:1 is prepared into an additive solution with a mass concentration of 30% using triacetic anhydride grease as a solvent, and the prepared additive solution is sprayed according to the weight of each kilogram of tow during the filter rod forming process 119.0 grams of the additive solution are sprayed on the filter tow, and then made into a filter rod according to the conventional process, and finally rolled into cigarettes, the theoretical addition amount of the additive in each cigarette is 5 mg (the amount of the tow in each cigarette is based on 0.14 g meter).

[0029] Control sample: Spray triacetic anhydride oil on the filter tow during the filter rod forming process, then make filter rods according to the conventional process, and finally roll into cigarettes. The same amount was used in the samples.

Abstract

The invention relates to a method for improving the particle size distribution concentration degree of cigarette aerosols, and belongs to the technical field of cigarettes. The method specifically comprises the steps of preparing an additive which is composed of glycerin and furanone according to a certain proportion into a solution with certain concentration, and afterwards, adding the solution to different parts of the cigarettes. By means of the method for improving the particle size distribution concentration degree of the cigarette aerosols, the distribution proportion of aerosols with the small particle diameters can be reduced, the distribution proportion of the aerosol particles with the middle particle diameters is increased, thus the thus distribution of smoke aerosols with the middle particle diameters is more centralized, and the deposition proportion of the smoke aerosols with the large particle diameters in the oral cavity and the nasal cavity is increased, so that cigarette smoke is richer, the sensory quality of the smoke is improved, the smoke aerosols with the small particle diameters entering the respiratory tract and the lung are reduced, and the safety of the cigarette smoke is improved.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, in particular to a method for improving the distribution concentration of cigarette aerosol particles. Background technique [0002] Cigarette smoke is an aerosol composed of thousands of chemical components. It is composed of particles of different particle sizes. The aerosol particles have the characteristics of uneven distribution, small change scale, and complexity. state distribution function. Due to the different deposition conditions of aerosol particles with different particle sizes in the human respiratory system, relatively speaking, most aerosol particles with large particle sizes remain in the mouth and nasal cavity, which has a greater impact on the sensory quality of smoke; aerosols with small particle sizes are mainly in the Deposition in the lungs and trachea has a greater impact on health. Therefore, changing the particle size distribution of cigarette smoke aerosol can chang...
