Description

Technical Field

[0001] This invention relates to the field of cigarette production technology, and in particular to a method for controlling the purity of cigarettes. Background Technology

[0002] Tobacco constitutes a large proportion of cigarettes, and its quality directly affects the overall taste of the cigarette and the consumer's experience. Even after drying, tobacco often still contains many tangled clumps, wet clumps, charred pieces, stems, and other components, which affect the structure of the tobacco and the quality of the finished cigarette.

[0003] The stems and fibrous parts in the tobacco leaves affect the consistency of the sensory quality of cigarettes. Some finished cigarettes may even exhibit popping or tilting during combustion. Furthermore, this can lead to weight deviations and cigarette pack misalignment during the rolling process. It also affects the appearance of the cigarettes, and in severe cases, the stems and fibrous parts can puncture the cigarette paper. Therefore, it is necessary to control the purity of the tobacco leaves during production to ensure the physical and sensory quality of the cigarettes. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to disclose a method for controlling the purity of cigarettes. This method adjusts the amount of stems and stalks removed by air separation during the cigarette making and tobacco processing stages, thereby reducing the content of stems and stalks in the tobacco and leaves, thus ensuring the purity of the produced cigarettes and guaranteeing the smoking experience.

[0005] Specifically, the method for controlling the purity of cigarettes according to the present invention includes the following steps:

[0006] S1: Calculate the percentage of cigarettes containing tampers produced. If the percentage of cigarettes containing tampers is not less than 3% per 100 cigarettes, the purity of the cigarettes is deemed substandard, and proceed to step S2.

[0007] S2: Adjust the ratio of stems and twigs removed by air separation of tobacco shreds during the cigarette rolling process, and then recalculate the twig content of the produced cigarettes. If the cigarette purity meets the standard, proceed to the next process. If it does not meet the standard, repeat step S2 until the shred content of stems and twigs reaches the upper limit of the standard, and then proceed to step S3.

[0008] S3: Adjust the ratio of leaf shreds to stems during the tobacco processing, and then repeat step S2. If the tobacco purity meets the standard, proceed to the next process. If the stem content in the cigarette reaches the upper limit of the standard, but the percentage of cigarettes with stems still does not meet the standard, repeat step S3.

[0009] Furthermore, step S2 specifically includes:

[0010] S21: Statistical analysis of the percentage of stems and twigs removed from tobacco during the current cigarette-making process;

[0011] S22: Test the stem content of the current cigarette rolling process and compare it with the standard value of stem content. If it does not reach the upper limit of the standard value, adjust the amount of stem removed by the tobacco air separation and calculate the ratio N of stem removed by the tobacco air separation in the cigarette rolling process after adjustment.

[0012] S23: If the retesting and statistical analysis of the amount of tobacco sticks produced still does not meet the technical requirements, repeat the aforementioned steps until the amount of tobacco sticks reaches the upper limit of the standard.

[0013] Furthermore, when the circumference of the cigarette is 19mm, the values ​​of M and N range from 2.3% to 3.5%.

[0014] When the circumference of the cigarette is 20mm, the values ​​of M and N range from 2.3% to 3%.

[0015] When the circumference of the cigarette is 22.5mm, the values ​​of M and N range from 2.3% to 3%.

[0016] Furthermore, in step S22, the standard value for the filament content of the stem is 15%-30%.

[0017] Furthermore, step S3 specifically includes:

[0018] S31: Statistical analysis of the percentage of stems and twigs removed by air separation during the current silk-making process;

[0019] S32: Test the filament content of the stems in the current silk-making process and compare it with the standard filament content of the stems. If it does not reach the upper limit of the standard value, adjust the amount of stems removed by the leaf filament air separation and statistically analyze the ratio Z of stems removed by the leaf filament air separation in the silk-making process after adjustment.

[0020] S33: Repeat step S2;

[0021] S34: If the purity of the cigarette meets the standard, proceed to the next process. If the amount of shredded stems in the cigarette rolling process reaches the upper limit of the standard, but the shredded stem content of the cigarette still does not meet the standard, repeat the above steps and increase the amount of shredded stems removed by the leaf air separation in the cigarette making process until the shredded cigarette content meets the standard requirements. Statistically calculate the ratio of shredded stems removed by the leaf air separation in the cigarette making process after adjustment, Z1.

[0022] Furthermore, the leaf filament air separation and stem removal ratio is the ratio of the total weight of leaf filaments with stems removed in each production batch to the total weight of leaf filaments in each production batch before drying.

[0023] Furthermore, when the circumference of the cigarette is 19mm, the values ​​of Y, Z, and Z1 range from 0.2% to 0.8%.

[0024] When the circumference of the cigarette is 20mm, the values ​​of Y, Z, and Z1 range from 0.2% to 0.5%.

[0025] When the circumference of the cigarette is 22.5 mm, the values ​​of Y, Z, and Z1 range from 0.2% to 0.5%.

[0026] Furthermore, when the circumference of the cigarette is 19mm, the standard value for the filament content of the stem in step S32 is 2%-5%.

[0027] When the circumference of the cigarette is 20mm, the standard value of the filament content of the stem in step S32 is 1%-5%.

[0028] When the circumference of the cigarette is 22.5 mm, the standard value for the filament content of the stem in step S32 is 1%-5%.

[0029] The beneficial effects of this invention are:

[0030] This invention discloses a method for controlling the purity of cigarettes. It adjusts the amount of stems removed by air separation during the cigarette making and tobacco processing, thereby reducing the stem content in the tobacco and leaves, thus ensuring the purity of the produced cigarettes and the taste of the cigarettes. No additional processes are required, the process is simple, and it is conducive to widespread use. Detailed Implementation

Statistically calculate the percentage of shredded tobacco removed by the leaf air separation in the cigarette making process after adjustment, Z1.

[0047] The leaf filament air separation and stem removal ratio is the ratio of the total weight of leaf filaments with stems removed in each production batch to the total weight of leaf filaments before drying in each production batch. The value ranges of Y, Z, and Z1, and the standard values ​​of stem filament content are shown in Table 2.
