Description
Technical Field
The invention relates to a cigarette production process, in particular to a method for reducing the loss of a cigarette stem removing process by reducing the stem content in leaves.
Background
At present, cigarette production, especially production of fine cigarettes, generally has the problems of large cigarette weight and fluctuation of suction resistance, easy falling of a cigarette combustion cone, more bamboo joint cigarettes and hollow cigarettes, broken cigarettes and the like, and the analysis reason is caused by high content of stems in tobacco shreds, so that the cigarette industry must adopt a stem removing process in the production process to reduce the content of the stems in the tobacco shreds, but the process loss is large in the stem removing process due to limited technical conditions at present, and great economic loss is generated.
According to survey statistics, the tobacco shred loss of the conventional cigarette caused by removing the stems is about 0.1 Kg/box, and the tobacco shred loss of the slim cigarette caused by removing the stems is about 0.3 Kg/box; the tobacco shred loss is 35 ten thousand Kg as measured by the productivity measurement of 200 ten thousand boxes of conventional cigarettes and 50 ten thousand boxes of slim cigarettes each year. According to the rough measurement of the amount of the tobacco consumed by the single box of cigarettes at present, the number of the converted cigarettes is about 1 ten thousand boxes; that is, 1 ten thousand boxes of cigarettes are lost each year due to stalk removal, and if the economic value is further converted, the economic value loss is too large.
The root of these problems is the high stem content in the leaves of all the raw tobacco lamina material in cigarette production. According to the current industry standard requirement, the stem content in the tobacco leaves is basically about 2.0 percent, but the stem content mainly refers to the tobacco stems with the diameter of more than 1.5mm, and the capillary stems with the diameter of less than 1.5mm are not counted into the stem content of the tobacco strips, and the capillary stems with the diameter of less than 1.5mm are the real reason of high cut tobacco stem tip content. In addition, the capillary stems with the diameter less than 1.5mm are also tobacco stems which are difficult to remove in the threshing and redrying process, and can be removed only by adopting special threshing equipment and a personalized process.
The invention solves the problem that the tobacco industry is difficult to solve in the processes of manual stem picking, tobacco shred making, stem picking by wind, rolling and stem picking by reducing the key technical application of free stems, leaf-carrying stems, capillary stems and the like in the tobacco sheets from the tobacco processing source.
