Embodiment 1

[0022] The sample is a domestic brand of flue-cured tobacco

[0023] a. Take a pack of cigarettes of this brand and place them in an environment with a temperature of 20±2°C and a humidity of 65%±5% to balance for 24 hours, then take 5 cigarettes, take out the shredded tobacco and weigh the net weight as 2.8397g.

[0024] b. Under the magnifying glass, select shredded leaves, expanded stems, paper-making flakes, rolled flakes, and non-expanded stems according to the different appearance characteristics of various shredded tobacco. 0.0g.

[0025] c. Select ethyl acetate and cyclohexane as solvents, and blend them at a volume ratio of 1:2, with a density range of 0.83±0.02.

[0026] d. Put the shredded leaves into a beaker and add about 50ml of solvent. Let stand for about 2 minutes after stirring with a glass rod. Take out the expanded leaf shreds floating on the liquid surface, put it into an oven and dry it for one minute at about 100°C. Weigh and record as 0.2774g

Abstract

A method for measuring the proportion of shredded tobacco in a cigarette, the specific steps of the method are as follows: a. Put the cigarette in an environment with a temperature of 20±2°C and a humidity of 65%±5% to balance for 24±2 hours, and then take out the cigarette Tobacco in the branch, and weigh the net weight, recorded as W; b. Under the magnifying glass, select leaf shreds, expanded stems, paper sheets, rolled sheets, and non-expanded stems under the magnifying glass according to the different appearance characteristics of various tobacco cuts, and weigh them And record it as A, B, C, D, E in turn; c, put the shredded leaves into the container, add a volatile organic solvent with a density range of 0.83±0.02, stir and let it stand for 1 to 3 minutes, take out and float on the The expanded shredded leaves on the liquid surface are put into an oven and dried at 90-110°C, weighed and recorded as P; d. Through calculation, the proportions of various shredded tobaccos can be obtained. The present invention provides a comparatively complete and feasible method for quickly and accurately measuring the blending ratios of various shredded tobaccos in cigarettes, and can provide reliable technical parameters for correctly controlling the ratios of shredded tobaccos mixed in cigarettes.

Description

technical field [0001] The invention relates to a method for measuring the ratio of shredded tobacco in a cigarette, in particular to a method for separating different kinds of shredded tobacco and measuring the blending ratio of different kinds of shredded tobacco. technical background [0002] Each brand of cigarettes has certain style and quality characteristics. The style and characteristics of cigarettes are determined by factors such as their formula, processing, flavoring and ingredients, and selection of auxiliary materials. The formula is the premise of forming the style characteristics of the product. With the implementation of the "Framework Convention on Tobacco Control", cigarette manufacturers at home and abroad put the reduction of tar and harm, reduction of production costs and stable product style and characteristics in the first place. Due to the large proportion of the cost of tobacco leaves in the cost of cigarettes and the characteristics of high tar r...
