Problems solved by technology

[0004] In the traditional processing process, it is limited to improve the flavor absorption of shredded leaves by adjusting the processing parameters of the equipment
A large number of experiments have shown that for medium and high-grade high-quality leaf silk, when the process gas treatment temperature is higher than 100°C, the aroma of the dried leaf silk will be significantly worse, and the amount of aroma will also be significantly reduced. Obviously, only by adjusting the existing drying The process parameters in the method cannot meet the lower processing intensity requirements, and cannot meet the quality requirements of leaf shred moisture and odor absorption at the same time
On the other hand, neither the convect

Embodiment 1

[0012] Experiment No. 1 leaf shreds 1800kg, balance the moisture content to 20%, and then import it into the airflow drying equipment by lifting the material belt. The temperature control range of the airflow in the first zone is 80-90℃; The temperature of the back leaf shreds is 40°C, and the moisture content is 16%. The leaf silk with a moisture content of 16% after drying is introduced into the drum drying equipment by lifting the material belt. The temperature of the cylinder wall is set at 80°C. After drying again, the outlet leaf silk temperature is 45.4°C and the moisture content is 12.55%. The water content of cut leaves after treatment in this example is shown in attached table 1, the temperature of cut leaves after treatment is shown in attached table 2, the filling value of shredded leaves after treatment is shown in attached table 3, and the sensory evaluation results of shredded leaves after treatment are shown in Table 2 As shown in Attached Table 4, the chemical...

Embodiment 2

[0014] Experiment No. 2 shredded leaf is 1800kg. After the moisture content is balanced to 20%, it is introduced into the airflow drying equipment by lifting the material belt. The temperature control range of the airflow in the first zone is 85-95℃; The temperature of the back leaf shreds is 42°C, and the moisture content is 15%. The leaf silk with a moisture content of 15% after drying is introduced into the drum drying equipment by lifting the material belt. The temperature of the cylinder wall is set at 75°C. After drying again, the outlet leaf silk temperature is 43.6°C and the moisture content is 12.55%. The water content of cut leaves after treatment in this example is shown in attached table 1, the temperature of cut leaves after treatment is shown in attached table 2, the filling value of shredded leaves after treatment is shown in attached table 3, and the sensory evaluation results of shredded leaves after treatment are shown in Table 2 As shown in Attached Table 4,...

Embodiment 3

[0016] Experiment No. 3 leaf shreds 1800kg, balance the moisture content to 20%, and then import the material belt into the air drying equipment through the lifting material belt. The temperature control range of the air flow in the first area is 90-100°C; The temperature of the back leaf shreds is 45°C, and the moisture content is 14%. The leaf silk with a moisture content of 14% after drying is introduced into the drum drying equipment by lifting the material belt. The temperature of the cylinder wall is set at 70°C. After drying again, the outlet leaf silk temperature is 41.9°C and the moisture content is 12.54%. The water content of cut leaves after treatment in this example is shown in attached table 1, the temperature of cut leaves after treatment is shown in attached table 2, the filling value of shredded leaves after treatment is shown in attached table 3, and the sensory evaluation results of shredded leaves after treatment are shown in Table 2 As shown in Attached Ta...

Abstract

The present invention discloses a cut tobacco -drying technics during processing cigarette, which comprises two steps: the first step is to balance the water content of cut tobacco to 20 percent, and the cut tobacco is guided into a pneumatic drier, wherein the technics air temperature in the first section of pneumatic drier is controlled between 80 and 100 DEG C, and that in the second section is controlled between 70 and 90 DEG C, then the cut tobacco with 20 percent water content is dried and the water content is lowered to about 14 to 16 percent; and the second step is that the dried cut tobacco is guided into a roller dry machine for the secondary drying procedure, wherein the temperature of the wall of the roller is controlled between 70 and 80 DEG C, to control the water content of the dried cut tobacco between 12.0 percent and 13.0 percent. The present invention can not only improve both the uniformity of the water content and temperature stability of the processed tobacco with increased filling capability of the dried tobacco, but also reduce the loss of the fragrance of tobacco, to significantly decrease the content of injurious ingredients contained in cigarette such as tar, smoke and nicotine.

Description

technical field [0001] The invention relates to a material drying process, in particular to a leaf shred drying method in the cigarette processing process. Background technique [0002] Drying is the most important production link in the cigarette processing process. Its basic task is to remove part of the moisture in the tobacco material, improve its filling capacity and processing resistance, and at the same time improve the flavor of the tobacco material and reduce irritation and miscellaneous gas. [0003] There are two main drying methods for tobacco materials. One is the convective drying method, which achieves the purpose of drying and dehumidification through the convective heat transfer between the high-temperature air flow and the leaf (stem) silk. The other is the conductive drying method, which achieves the processing quality requirements through the slow conduction between the drum wall and the leaf silk. Regardless of the airflow drying method or the drum dryi...
