Problems solved by technology

In order to achieve a better loosening effect for the tobacco sheets, the return air temperature of the current loosening and moisture regaining equipment is mostly about 65°C. Under this condition, the aroma and aroma of the high-grade tobacco leaf raw materials are greatly lost. Therefore, the high-grade tobacco leaf raw materials need to be at a lower temperature In order to more effectively develop the potential and use value of tobacco leaves
However, under this condition, the loosening effect is poor, and the loosening rate of the smoke sheet is mostly between 90% and 95%, which cannot well complete the task of loosening and regaining moisture.
[0004] (2) The smoke sheet is heated unevenly in the process of loosening and regaining moisture
One is that the tobacco leaf raw materials are pressed into blocks for storage and transportation after threshing and re-baking. The block materials enter the loosening and dampening drum, and a small part of the tobacco leaves in the center of the material cannot be effectively dispersed. heated
The second is that the change of steam flow makes the scattered smoke sheet heated unevenly
[0005] (3) The current loose moisture regain equipment has a high breakage rate
When the cigarette block enters the drum-type tobacco leaf dampening machine, it is difficult for the blocky material to regain moisture in a short time. Due to the rotation of the drum, the rakes and lifting plates in the drum will lift up the cigarette block and then drop it. Larger crushing, so the traditional loose moisture regaining method has a high tobacco leaf crushing rate in the drum-type tobacco leaf moisture conditioning machine

Embodiment 1

[0036] Such as figure 1 As shown, the unboxed cigarette bale was cut into 1 slice, and the slice direction was perpendicular to the layering direction of the tobacco leaves in the pack into 3 slices. The slices were cut with multi-knife thin cuts, and the slice thickness of the cut tobacco block was 80 mm. After cutting, the cigarette block 4 is turned over 90° by the traction of the box-turning mechanism 5 and then placed on the moving mesh belt (or mesh plate) 6 of the tunnel type pre-increasing moisture regain loosening machine. The layering direction of the cigarette block 4 is perpendicular to the moving mesh belt ( Or stencil) 6 sides. After cutting, the cigarette block adopts a stable release mechanism (that is, the box turning mechanism), so that the cigarette block can be placed neatly on the downstream equipment, and the posture meets the requirements.

Embodiment 2

[0046] Such as figure 1 As shown, the unboxed cigarette bale was cut into 1 slice, and the slice direction was perpendicular to the layering direction of the tobacco leaves in the pack into 3 slices. The slices were cut with multi-knife thin slices, and the slice thickness of the cut tobacco block was 150 mm. After cutting, the cigarette block 4 is turned over 90° by the traction of the box-turning mechanism 5 and then placed on the moving mesh belt (or mesh plate) 6 of the tunnel type pre-increasing moisture regain loosening machine. The layering direction of the cigarette block 4 is perpendicular to the moving mesh belt ( Or stencil) 6 sides.

Embodiment 3

[0056] Such as figure 1As shown, the unboxed cigarette bale was cut into 1 slice, and the slice direction was perpendicular to the layering direction of the tobacco leaves in the pack into 3 slices. The slices were cut in a multi-knife thin-cut method, and the slice thickness of the cut tobacco block was 220 mm. After cutting, the cigarette block 4 is turned over 90° by the traction of the box-turning mechanism 5 and then placed on the moving mesh belt (or mesh plate) 6 of the tunnel type pre-increasing moisture regain loosening machine. The layering direction of the cigarette block 4 is perpendicular to the moving mesh belt ( Or stencil) 6 sides.

Abstract

The invention provides a loosening and dampening method of tobacco leaves under condition of low intensity, which comprises the following steps of: packing the cigarettes in a divider to be divided into blocks, performing pre-warming dampening and loosening via a pre-warming and moistening treatment link and then performing warming moistening and loosening treatment via a hot wind loosening and dampening link at a constant flow for the tobacco leaves subjected to the pre-warming dampening and loosening treatment. The warming moistening and loosening treatment is carried out on the divided blocks under condition of low intensity (the temperature of the passing tobacco leaves is below 50 DEG C) by comprehensively utilizing various loosening and dampening methods such as warming method, moistening method, mechanical method, and the blocks are heated uniformly in the whole loosening and dampening process, thus the loosening rate of the blocks is improved, the crushing rate is reduced, thepurpose of reducing the fragrance loss of the tobacco leaves is achieved and the essence of the tobacco especial for high-class tobacco is maintained to a maximum extent.

Description

technical field [0001] The invention relates to a method for loosening and dampening tobacco leaves in the tobacco industry, in particular to a method for loosening and dampening tobacco leaves under low-strength conditions. Background technique [0002] According to the requirements of group processing with special techniques, in the tobacco leaf loosening and rehydration process, high-intensity treatment conditions should be adopted for middle and low-grade tobacco leaf raw materials to remove tobacco miscellaneous gases, reduce irritation, and improve the quality of tobacco leaves; high-grade tobacco leaf raw materials should be treated with low-intensity treatment Conditions (the temperature of the processed tobacco leaves ≤ 50°C, the same below), in order to reduce the aroma loss of the tobacco leaf raw materials and retain the unique tobacco fragrance of the high-grade raw materials to the greatest extent. However, the research and application show that the existing lo...
