Problems solved by technology

In addition, the length of shredded tobacco is also closely related to the shape of the leaves. At present, the leaves produced by threshing and redrying are mostly elongated or wicker-shaped. It meets the requirements of suitable shredded tobacco structure. Therefore, while improving the structure of the blade, the shape of the blade must also be further improved

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...

Abstract

The invention provides a method for optimizing cut tobacco structure by improving structure and shape of threshed and re-dried tobacco leaves; an orthohexagonal frame railing is adopted by the first turn of a threshing section, the dimensions of the frame railng are in the combination of 2.5''-3.5'', and corresponding rolling rate is regulated to be 40-45Hz; the 2.5'' combination of an orthohexagonal frame railing and a rhombic frame railing is adopted by the second turn, and corresponding rolling rate is regulated to be 30-35Hz; a 2.5'' rhombic frame railing is adopted by the third turn, and corresponding rolling rate is regulated to be 35-40Hz; a 2.0'' round frame railing is adopted by the fourth turn and the fifth turn, and corresponding rolling rate is regulated to be 30-40Hz; the rotation speed of a corresponding pneumatic separating fan for 1-12 pneumatic separation is regulated to be 40-50Hz; and the temperature of a corresponding re-drying section is regulated to be 60-80 DEG C, the temperature of a cooling area is regulated to be 35-40 DEG C and the temperature of a resurgence area is regulated to be 60-70 DEG C. By virtue of the method disclosed by the invention, a large-leaf rate can be effectively reduced while a medium-leaf rate and a small-leaf rate can be improved, and chip and dust rate can be controlled, so that appropriate raw material basis is provided for the optimization of cut tobacco structure.

Description

Technical field [0001] The invention relates to a cigarette production process, in particular to a method for optimizing the shredded tobacco structure by improving the structure and shape of threshing and redrying leaves. Background technique [0002] With the full use of sliced ​​tobacco, threshing and redrying has also become an indispensable and important link in the cigarette industry. Threshing and redrying is not only the separation and redrying of tobacco leaves and stalks, but also plays an important role and significance for the quality of late-stage silk making, formula and quality. Leaf structure refers to the proportion of leaves of different sizes in the leaves after threshing. It is an important indicator to measure the quality of threshing and is also the main factor affecting the structure of tobacco. The structure of tobacco determines the quality of cigarettes (such as the weight of a single cigarette). , Cigarette density, end thread amount, short end rate an...
