Problems solved by technology

This method only characterizes the mixing degree of cigarette leaf groups in each process before shredding, and cannot characterize the blending ratio and uniformity of reconstituted tobacco leaves in finished shredded tobacco and cigarettes after shredding
[0004] In the prior art, there is no relevant report on using the total ash value as a marker to characterize the blending ratio of reconstituted tobacco cigarettes

Embodiment 1

[0026] A method for detecting the blending uniformity of reconstituted tobacco leaf cigarettes includes the following steps:

[0027] Take about 1000 grams of tobacco leaves and about 500 grams of reconstituted tobacco leaves that are representative of a certain cigarette brand without remanufactured tobacco leaves, and bake them in an oven at 105°C for 2 hours (to the absolute dryness), and then pulverize them. The difference in ash content of cigarette formula tobacco leaves is 7.52%;

[0028] Add 0%, 3%, 6%, 9%, 12%, 16%, 20% of the pulverized reconstituted tobacco to the pulverized cigarette formula tobacco powder, respectively, and test the total ash value;

[0029] Analyze the detection data, find the correlation between the blending ratio of reconstituted tobacco in the cigarette leaf group formula and the total ash value through the scatter diagram, and obtain the correlation formula, that is, the linear equation between the blending ratio and the ash value:

Embodiment 2

[0037] A method for detecting the blending ratio of reconstituted tobacco leaf cigarettes includes the following steps:

[0038] (1) Take about 1,000 grams of tobacco and 500 grams of reconstituted tobacco, which are representative of a certain cigarette brand without remanufactured tobacco, and bake them in an oven at 105°C for 2 hours (to dryness), and then pulverize them. The difference in ash content between reconstituted tobacco and cigarette formula tobacco is 6.82%;

[0039] (2) Add 0%, 2%, 6%, 10%, 14%, 18% of the pulverized reconstituted tobacco to the pulverized cigarette formula tobacco powder, and test the total ash value of different samples. ;

[0040] (3) Analyze the detection data, find the correlation between the blending ratio of reconstituted tobacco in the cigarette leaf group formula and the total ash value through the scatter diagram, and obtain the correlation formula:

[0041] Y=16.237X-199.17, R 2 =0.9981

[0047] A method for detecting the blending ratio of reconstituted tobacco leaf cigarettes includes the following steps:

[0048] (1) Take about 1,000 grams of tobacco and 500 grams of reconstituted tobacco, which are representative of a certain cigarette brand without remanufactured tobacco, and bake them in an oven at 105°C for 2 hours (to dryness), and then pulverize them. The difference in ash content between reconstituted tobacco and cigarette formula tobacco is 5.0%;

[0049] (2) Add 0%, 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18%, 20% to the pulverized cigarette formula tobacco powder. The reconstituted tobacco leaves are tested for the total ash content;

[0050] (3) Analyze the detection data, find the correlation between the blending ratio of reconstituted tobacco in the cigarette leaf group formula and the total ash value through the scatter diagram, and obtain the correlation formula:

Abstract

The invention discloses a method for detecting the blending proportion of reconstituted tobacco cigarette. The method comprises the following steps: (1) baking representative cigarette formula tobaccowithout reconstituted tobacco of a cigarette brand and pure reconstituted tobacco till the two are absolutely dry, and pulverizing the two separately; (2) separately adding 0% to 20% of the pulverized reconstituted tobacco into the pulverized cigarette formula tobacco, and respectively detecting the total ash value; (3) analyzing detection data and looking for the correlation between the blendingratio of the reconstituted tobacco in cigarette blending formulation and the total ash value, so as to obtain a linear equation between the blending proportion and the ash value; (4) sampling the finished cut tobacco or the finished cigarettes at uniform interval on line, crushing the samples, detecting the ash value, substituting the ash value into the linear equation, so as to obtain the blending proportion of the reconstituted tobacco in the finished cut tobacco. The detection method is simple and feasible, has the characteristics of being more scientific and precise than an existing manual sorting method, and provides technical support for precise regulation of cigarette formula.

Description

Technical field [0001] The invention relates to the technical field of reconstituted tobacco by papermaking, in particular to a detection method for the blending ratio and blending uniformity of reconstituted tobacco. Background technique [0002] Paper-making reconstituted tobacco is one of the main raw materials of cigarettes. The raw materials used in reconstituted tobacco are mainly threshing and redrying, tobacco stems, stalks, tobacco dust and other wastes in the cigarette production process, and some low-grade tobacco leaves that are difficult to use in formulas. In order to improve the adaptability of papermaking and the drainage performance of the slurry, 5%-10% calcium carbonate is usually added to the slurry. The existing remanufactured tobacco leaves are mixed with tobacco during the process of cigarette processing, and there are problems such as shredding and running, low shredding qualification rate, and filament entanglement. The existence of these problems makes t...
