A kind of preparation method of shredded tobacco stem

A technology for tobacco cut stems and tobacco products, which is applied in the process of rolling or defibrating tobacco stems, tobacco and tobacco cut stem preparation fields, and can solve the problems affecting the compatibility between cut stems and cut leaves and the uniformity and uniformity of component mixing. The degree, fullness, and vividness need to be improved, and the physical shape of the leaf silk is very different, so as to achieve the effect of outstanding physical quality indicators and sensory quality, high overall smoking quality, and rich tobacco flavor.

Problems solved by technology

[0004] At present, most of the dry cut stems in the industry are airflow or tunnel drying methods. These two drying methods can make the cut stems obtain a higher filling rate, which is beneficial to the reduction of coke and consumption of cigarette products; but these two drying processes The cut stems produced are mostly flakes, which are quite different from the shredded leaves in physical form, which affects the compatibility of the shredded stems and shredded leaves and the uniformity of component mixing
The shredded stem technology used in traditional tobacco stems is shredded first and then expanded, and the processing intensity in the drying and swelling stage is low. The shredded stem technology cannot fully meet the requirements of cigarettes in the following aspects: ① texture of tobacco stems Tightness, poor wettability, poor absorption effect on feed liquid, feed liquid sprayed on the surface, feed liquid can not guarantee effective penetration and absorption; ②Poor blending uniformity, homogenization level is affected; ③Due to insufficient expansion and If the air selection is not eliminated, it will cause bursting and burning cones to fall; ④The color transfer quality of the stalks is poor, and the uniformity, fullness, and vividness of the color need to be improved, which directly affects the blending ratio of cut stalks in cigarettes and utilization rate; ⑤The processing intensity is low, resulting in heavier miscellaneous gas and greater irritation when smoking cigarettes

Abstract

The invention discloses a tobacco stem preparation method. The tobacco stem preparation method comprises the following steps: (1) tobacco stem pretreatment: preparing tobacco stem raw materials into homogeneous-morphology tobacco stems; (2) stem moistening: pumping vapor into the tobacco stems processed in the step (1) to perform stem moistening till the moisture content is 35-40%, and balancing moisture for 180-240 min; (3) defibering and stem stripping: feeding the tobacco stems processed in the step (2) into a fluffer to perform defibering and stem stripping, wherein after defibering and stem stripping, the moisture content of the stems is 30-35%; (4) stem expanding: expanding the stems processed in the step (3) by use of high-pressure vapor till the expansion rate is 50-80%; (5) stem drying: performing tunnel-type hot-air three-stage drying on the stems processed in the step (4); and (6) screening. The prepared tobacco stems is high in filamentation rate, uniform in filamentation, appropriate in structure, good in elasticity and toughness, higher in smoking quality than traditional tobacco stems and strong in cigarette adaptability.

Description

technical field [0001] The invention belongs to the fields of tobacco, shredded tobacco stem rubbing or defibrating technology, and preparation of shredded tobacco stems, and in particular relates to a preparation method of shredded tobacco stems. Background technique [0002] Tobacco stems are an important part of tobacco leaves. Tobacco stems, which account for about 25% of the mass of tobacco leaves, can be obtained after separation of tobacco leaves. Tobacco stems can be processed into shredded stems, which are one of the filling materials for cigarettes. The treated stems had a higher filling value and lower tar release compared to the shredded leaves. Adding a proper amount of shredded stems to the cigarette formula can not only make full use of tobacco leaf resources and reduce production costs, but also effectively reduce the amount of tar in cigarettes and improve the safety of cigarette products. Because cut stems have certain inherent sensory quality defects, the...
