Abstract

The invention belongs to the field of tobacco products, and relates to a method for drying tobacco shreds, which comprises the following steps: (1) drying the tobacco shreds to obtain a 50-80 DEG C dried material; (2) treating the dried materials through a vibration tank, wherein the conveying speed ranges from 0.26 m/s to 0.35 m/s, the time ranges from 35 s to 50 s, the vibration frequency rangesfrom 4.10 Hz to 4.70 Hz, the amplitude ranges from 23 mm to 30 mm, and first materials are obtained; (3) conveying the first material by using a belt conveyor at a conveying speed of 0.6-0.7 m/s for8-40 seconds, and performingcooling to obtain a second material; (4) carrying out airflow separation on the second material at the airflow velocity of 4.3-6.8 m/s and the temperature not higher than that of the second material to obtain a material; (5) treating the material obtained in the step (4) in a vibration tank to obtain a third material; and (6) performing third material airflow separation. The invention relates to tobacco shreds, tobacco products and application. According to the method, the tobacco shred breakage rate is reduced, the filling value is increased, the ratio of macular cigarettes to mildewed cigarettes is reduced, and the sensory quality of cigarettes is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco products, and in particular relates to a method for drying shredded tobacco, and also relates to the prepared shredded tobacco, tobacco products and applications of the shredded tobacco. Background technique [0002] In the process of cigarette production and processing, shredded tobacco drying is an important process in cigarette shredding, which directly affects the sensory quality and physical quality of the product. The main purpose of shredded tobacco drying is to obtain the moisture content of shredded tobacco suitable for rolling cigarettes. During the shredded tobacco drying process, it is also necessary to remove stems, wet lumps, and soot dirt in the shredded tobacco material. Among them, the stem stick refers to the small-sized strip tobacco stem contained in the shredded tobacco material, and its hazard is that it is easy to pierce the cigarette, causing the fluctuation of the smoke in...
