Embodiment 1
[0012] Example 1: A method for optimizing the shredded tobacco structure by improving the structure and shape of the threshing and redrying blades. In the threshing and redrying process, a quadruple of the threshing section adopts a regular hexagonal frame, and the frame size is 2.5" respectively. , 3.0″, 2.5″ and 3.5″, adjust the rolling speed to 43Hz; two-fighting and two-in-one use 2.5” regular hexagon and diamond frame, adjust the rolling speed to 31Hz; three-fighting use 2.5” diamond frame to adjust the rolling speed 40Hz; four dozens and five dozens use a 2.0" circular frame, respectively, and the rolling speeds are 35Hz and 40Hz respectively. The speeds of the air separation fan for one to twelve winds are 42Hz, 40Hz, 41Hz, 46Hz, 41Hz, 46Hz. , 42Hz, 45Hz, 43Hz, 45Hz, 50Hz and 50Hz; the temperature of drying zone one to four in the re-bake section is 65℃, 72℃, 79℃ and 65℃ respectively, the temperature of the cooling zone is 38℃, and the moisture regain zone one and two Th...
Embodiment 2
[0023] Example 2: Taking the processing of Hongda C3F tobacco leaves in Huili Redrying Plant in Sichuan as an example, the existing traditional technology mode (single diamond frame) and the method provided by the present invention (combination of different shapes of frame + corresponding process parameters) That is, the above-mentioned example 1) was tested, and the results showed that in the leaf structure after roasting, compared with the control sample, the rate of large pieces was reduced by about 56.2%, the rate of medium pieces was increased by about 28.5%, and the rate of small pieces was increased by about 66.5%. , The stalk-containing rate in leaves is reduced by about 71.25%. The silk making test showed that compared with the control sample, the proportion of cut tobacco on the test sample was reduced by about 22.5%, the proportion of cut tobacco on the 3.35mm net increased by about 26.8%, and the proportion of cut tobacco on the 1.70mm net increased by about 23.7%. ...
Embodiment 3
[0030] Example 3: Taking the processing of Baokang K326C3F tobacco leaves in Xiangyang Redrying Plant in Hubei Province as an example, the existing traditional technology mode (single diamond frame) and the method provided by the present invention (combination of frames of different shapes + corresponding process parameters) are respectively adopted, namely The above-mentioned Example 1) was tested and the results showed that in the leaf structure after roasting, compared with the control sample, the large slice rate of the test sample was reduced by about 52.7%, the medium slice rate was increased by about 36.5%, and the small slice rate was increased by about 59.9%. The stalk-containing rate in leaves was reduced by about 62.9%. The silk-making test showed that compared with the control sample, the proportion of tobacco cut on the 90mm net was reduced by about 21.1%, the proportion of tobacco cut on the 3.35mm net increased by about 12%, and the proportion of cut tobacco on th...
