Embodiment 1

[0013] Embodiment 1: A method for reducing the loss of the cigarette stem removal process by reducing the stem content rate in the leaves. In the leaf threshing and redrying link, 5 knives and six sections are cut when feeding; the leaf threshing section adopts trapezoidal knives, Arranged in the shape of a character; one dozen adjusts the rolling speed to 48Hz; two dozen adjusts the rolling speed to 37Hz; three dozen adjusts the rolling speed to 40Hz; four dozen and five dozen adjust the rolling speed to 38Hz and 43Hz respectively; one to twelve winds The fan speeds of air separation are 35Hz, 37Hz, 37Hz, 36Hz, 40Hz, 42Hz, 44Hz, 45Hz, 38Hz, 40Hz, 42Hz and 45Hz; ℃ and 70℃, the temperature in the cooling zone is 33℃, and the temperature in zone 1 and zone 2 of the resurgence zone is 68℃ and 72℃ respectively.

[0014] In the processed tobacco products, the stalk content in the leaves is reduced from 2% to less than 0.5%, and the capillary stalk content is reduced from 1.0% to 0....

Embodiment 2

[0024] Embodiment 2: Taking Hubei Xiangyang rebaking factory as an example to process tobacco leaves in the middle of Fangxian County, respectively adopt the existing traditional technology mode and the method provided by the present invention (raw material slitting + new type of knife + combination of different shapes of frame bars + corresponding process parameters , Promptly above-mentioned embodiment 1) test, the result shows: test sample compares with reference sample, and the stalk-containing rate in the leaf is down to 0.36% by 1.94%, and capillary stalk content is down to 0.22% by 0.95%. The results of the silk rolling test show that the amount of stems removed by silk rolling is reduced by 71.3%, the loss of cut tobacco is reduced by more than 66.4%, the cigarette stems are reduced by about 21.5%, the product quality is stable and the quality defects are significantly reduced.

Embodiment 3

[0025] Embodiment 3: Taking Hubei Enshi rebaking factory to process Xuanen central tobacco leaves as an example, adopt the existing traditional technology mode and the method provided by the present invention respectively (raw material cutting + new type of knife + combination of different shaped frames + corresponding process parameters , Promptly above-mentioned embodiment 1) test, the result shows: compared with control sample, the stalk-containing rate in the leaf is reduced to 0.42% by 1.89%, and the capillary stalk content is reduced to 0.35% by 1.11%. The results of the silk rolling test show that the amount of stalks removed by silk rolling is reduced by 76.2%, the loss of cut tobacco is reduced by more than 68.7%, and the tobacco stems are reduced by about 23.9%. The stability of product quality is significantly improved, and the quality defects are significantly reduced.

[0026] In summary, the present invention has a significant effect on reducing the stalk content ...

Abstract

The invention provides a method for reducing loss of a cigarette silver rejecting technology by reducing the silver content in leaves. The method is implemented as follows: tobacco leaves are first cut in a threshing and redrying link, and equipment and corresponding process parameters at a threshing section are combined, that is, tobacco leaves are cut into six sections 5 times during feeding; then, trapezoid threshing tools arranged triangularly are adopted; frame bar assemblies in different sizes and shapes are matched properly, and the process parameters at the threshing section, such as threshing roll speed, wind separation efficiency, are adjusted mainly. The threshing and tearing efficiency of first threshing can be effectively improved from 70% to 90% or above; the silver content of leaves can be reduced effectively, the silver content of tobacco leaves is decreased from 2% to 0.5% or below after threshing, the process quality requirement of cigarette production (particularly thin cigarettes) for raw materials with low silver content can be met effectively, and a proper raw material foundation is laid for silver rejection during cigarette production.

Description

technical field [0001] The invention relates to a cigarette production process, in particular to a method for reducing the loss in the process of removing stems from cigarettes by reducing the stem content rate in leaves. Background technique [0002] At present, in the production of cigarettes, especially the production of slim cigarettes, there are common problems such as large fluctuations in cigarette weight and draw resistance, easy falling off of cigarette burning cones, more bamboo and short cigarettes, and puncture of cigarettes. Therefore, the cigarette industry must adopt the stem removal process in the production process to reduce the stem content in shredded tobacco. However, due to limited technical conditions, the process loss in the process of stem removal is relatively large. , resulting in large economic losses. [0003] According to the investigation and statistics, the shredded tobacco loss of conventional cigarettes due to removal of stems is about 0.1Kg...
