Novel production process for cut tobacco stems

Abstract

The invention discloses a novel production process for cut tobacco stems. The novel production process comprises the steps as follows: carrying out vacuum moisture regaining and evaporating the stems; storing the stems; heating and humidifying; straightening the stems; pressing the stems; arranging the stems; cutting the stems; feeding; expanding and drying; and perfuming. According to the novel production process, the vacuum moisture regaining and stem evaporating mode is adopted for moisture regaining of the tobacco stems, so that the impurity gases in the tobacco stems can be removed and the smoke softness is improved. The thinly pressing and cutting mode is adopted, so that the physical forms of the formed cut stems are threadlike and are closer to cut tobaccos. The flash evaporation, expansion and drum drying mode is adopted for drying of the cut stems, so that the cut stems are better in crimpiness and are closer to the form of the cut tobaccos and the filling capability of the cut stems can be improved. The cut steams produced by the production process has the advantages that the filling value is high, the impurity gases in the tobacco stems are reduced, the fragrance is increased, cigarettes can be endowed with a certain burned sweet fragrance, the physical forms of the cut stems are closer to the cut tobaccos, and the suitability is better in the cigarettes.

Description

technical field [0001] The invention relates to the technical field of methods for preparing shredded tobacco stems. Background technique [0002] Tobacco stems are an important part of tobacco, and after separation of stem leaves, tobacco stems accounting for about 25% of the total weight of tobacco leaves can be obtained. The nature of the chemical components contained in tobacco stems is basically the same as that of tobacco leaves. If the tobacco stems are properly processed and utilized to make cut stems with high filling value and shape close to shredded tobacco, they can be used as filling raw materials for cigarettes. [0003] There are mainly two kinds of existing tobacco stem processing techniques. The first method is that the tobacco stems are directly cut into shreds after being sieved and dampened, and the stems are stored, and then the cut stems are fed, expanded and dried; On the basis of the above method, after the stored tobacco stems are warmed, they are ...

Problems solved by technology

[0004] In order to change the shape of the cut stems, the existing technology is to use a double-cut cut stem treatment process. This process is to cut the stems after the first cut of the tobacco stems after screening and rehydration, and then perform the second cutting process. , see Chinese patent CN480074 and CN101444328, the shredded stalk after this process is close to the shape of shredded leaves, but there are two defects in this process: the one is that when the cut tobacco stem is shredded again, it is easy to cut the stem at the cutter. Scattering and "running pieces" phenomenon; the second is that after the second shredding, part of the cut stems are easily cut into shreds, resulting in a high rate of shredded stems, resulting in the weight, density and weight of cigarettes after rolling. Significant increase in suction resistance affects rolling quality
