Problems solved by technology

However, after the CTD airflow drying equipment replaces the original cut stem expansion and drying equipment in the traditional cut stem processing flow, the filling value of the processed cut stem is only 4.0cm 3 / g About 10% expansion rate, low usability as cigarette filling material

Embodiment 1

[0018] A process for drying cut stems by CTD airflow, including pressing and cutting tobacco stems after warming and humidifying, shredding, heating and humidifying (HT) cut stems, and drying cut stems by CTD airflow. The cutting width is 0.12mm, the material temperature at the outlet of the cut stem heating and humidification (HT) is controlled at 93°C, the flow rate of cut stems dried by CTD airflow is 2300kg / h, and the process gas temperature of the CTD expansion joint is 235°C.

[0019] After testing, the filling value of CTD air-dried cut stems has changed from 4.05cm 3 / g increased to 4.95cm 3 / g (the weight of the force measuring head is 3kg), the expansion rate is increased by 22%. The proportion of Zhenlong Class A special stalks used in Zhenlong (Xiangyun) increased from 7% to 12%, and the sensory quality score of cigarettes increased by 0.4 points; the leaf consumption of a single box of Zhenlong (Xiangyun) decreased from 35.52kg to 34.75kg . See the table below ...

Embodiment 2

[0022] A process for drying cut stems by CTD airflow, including pressing and cutting tobacco stems after warming and humidifying, shredding, heating and humidifying (HT) cut stems, and drying cut stems by CTD airflow. The cutting width is 0.10mm, the material temperature at the outlet of the cut stem is controlled to increase temperature and humidity (HT) to 95°C, the flow rate of cut stems dried by CTD airflow is 2500kg / h, and the process gas temperature of CTD expansion joint is 230°C.

[0023] After testing, the filling value of CTD air-dried cut stems has changed from 4.05cm 3 / g increased to 5.36cm 3 / g (the weight of the force measuring head is 3kg), the expansion rate is increased by 32%. The proportion of Zhenlong Class A special stalks used in Zhenlong (Xiangyun) increased from 7% to 12%, and the sensory quality score of cigarettes increased by 0.5 points; the leaf consumption of a single box of Zhenlong (Xiangyun) decreased from 35.52kg to 34.55kg . See the table ...

Embodiment 3

[0026] A process for drying cut stems by CTD airflow, including pressing and cutting tobacco stems after warming and humidifying, shredding, heating and humidifying (HT) cut stems, and drying cut stems by CTD airflow. The cutting width is 0.08mm, the material temperature at the outlet of the cut stem heating and humidification (HT) is controlled at 90°C, the flow rate of cut stems dried by CTD airflow is 2800kg / h, and the process gas temperature of the CTD expansion joint is 225°C.

[0027] After testing, the filling value of CTD air-dried cut stems has changed from 4.05cm 3 / g increased to 4.77cm 3 / g (the weight of the force measuring head is 3kg), the expansion rate is increased by 18%. The proportion of Zhenlong Class A special stalks used in Zhenlong (Xiangyun) increased from 7% to 12%, and the sensory quality score of cigarettes increased by 0.3 points; the leaf consumption of a single box of Zhenlong (Xiangyun) decreased from 35.52kg to 34.82kg . See the table below ...

Abstract

The invention belongs to the tobacco processing technical field, and in particular relates to a CTD pneumatic drying technology for stem. The pneumatic drying technology for stem CTD comprises the steps as follows: pressing the tobacco stem after increasing temperature and moistening, shredding, and CTD pneumatic drying the stem, the stem temperature increasing and increasing process (HT) is executed before the CTD pneumatic drying process for the stem, and the outlet temperature of the stem temperature increasing and increasing process (HT) is 90-95 DEG C. by adopting the technology, the filling value of CTD pneumatic drying for the stem can be raised, the inherent quality of the stem is effectively improved, the use ratio of the stem in the tobacco is raised and the tobacco cost is reduced.

Description

technical field [0001] The invention relates to a technique for CTD airflow drying of cut stems, which belongs to the technical field of tobacco processing. Background technique [0002] Tobacco stems are an important part of tobacco leaves, accounting for about 25% of the total weight of tobacco leaves. If the tobacco stems can be processed into high-quality shredded stems through reasonable processing, the utilization rate of tobacco leaf raw materials can be improved, waste can be reduced, and production components can be reduced. At the same time, the filling value of the shredded stem is 4.0-6.0cm 3 / g (the weight of the force measuring head is 3kg), which is 3.5-4.5cm higher than the filling value of shredded tobacco 3 / g (the weight of the force measuring head is 3kg) has obvious advantages. Using shredded stems in finished shredded tobacco can increase the filling capacity of shredded tobacco and the air permeability during combustion, improve the combustibility o...
