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. Ethyl acetate and cyclohexane are selected as solvents and blended 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

The invention relates to a method for testing the thread tobacco ratio of cigarette, which comprises: a, arranging the cigarette into the condition with the temperature as 20+-2 Deg. C and the humidity as 65+-5% to be balanced for 24+-2 hours, then taking out the thread tobacco from cigarette to be weighted as W; b, under the microscope, based on different appearances of variable thread tobacco, selecting thread tobacco, expanding thread, paper sheet, rolling sheet and non-expanded thread, to be weighed and recorded as A, B, C, D, E; c, inputting thread into container, and adding organic solvent whose density range is 0.83+-0.02 to be mixed and laid for 1-3 minutes, and taking out the expanding thread floating on the liquid to be input into bake stove at 90-110Deg. C to be weighted and recorded as P; d, calculating to obtain the ratios of different threads. The invention has high speed and high accuracy to support controlling the ratio of doping thread in cigarette.

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...
