Tobacco piece scattering regionalization dampening system and process

Abstract

The invention discloses a tobacco piece scattering regionalization dampening system and tobacco piece scattering regionalization dampening process. The tobacco piece scattering regionalization dampening system comprises a vertical splitting machine, a conveyor belt, a natural scattering splitting machine, a vibration type heating dampening scattering machine and a regionalization type polygon dampening drum which are arranged in sequence. The natural scattering splitting machine comprises an annular upper flexure belt, an annular lower flexure belt and rotary rollers arranged in the upper flexure belt and in the lower flexure belt. The vibration type heating dampening scattering machine comprises a vibration groove body, a cover body and a humid airflow device, wherein a grid plate is arranged in the vibration groove body. A drum body of the regionalization type polygon dampening drum is sequentially regionalized into a scattering region, a dispersed region, a humidification dampening region and a feeding region, and independent nozzles with different spraying angles are respectively installed on the regions. The tobacco piece scattering regionalization dampening system and the tobacco piece scattering regionalization dampening process achieve lower-temperature dampening of tobacco pieces, can keep tobacco smoking flavor, reduce smashing, improve the productivity of a tobacco factory and cigarette quality, reduce cigarette weight on the premise that preset cigarette quality standards are maintained, and thus reduce tobacco cost.

Description

technical field [0001] The invention relates to a tobacco sheet rehydration process and equipment used in the pretreatment process of tobacco thread, and specifically belongs to a tobacco block loose partition rehydration system and process. Background technique [0002] At present, slicing and dampening treatment processes are generally used in the tobacco pretreatment process on the domestic and foreign tobacco silk production lines. The equipment enters the damp chamber for loosening and dampening. The loose moisture regain of the cigarette block completely depends on the damp cylinder. The specific process is as follows: the unpacked cigarette packs pass through a vertical slitting machine, usually three cuts and four pieces, the cigarette blocks are arranged on the conveyor belt, weighed and measured, enter the dampening cylinder through the vibrating chute, and the cigarette blocks pass through The drum is turned and conveyed, and is moistened and heated by the forwa...

AI Technical Summary

Problems solved by technology

[0005] 1) The output block of the slicer is unstable, or folded, or dumped, and the smoke pieces are relatively broken, and the smoke pieces are irregularly arranged on the conveyor belt, which affects the stability of weighing and measuring and maintaining flow, thus affecting the follow-up Loose regain quality;

[0006] 2) The cut tobacco block directly enters the dampening cylinder under the condition of normal temperature and dry moisture (about 12%), and is directly affected by the rake nails at the feeding end of the dampening cylinder, which will cause a lot of crushing;

[0007] 3) The bulk material enters the dampening cylinder and is directly affected by the steam, which makes its core and surface heated unevenly, which affects the quality of the loose and dampened tobacco sheet;

[0008] 4) The low-temperature regain of the tobacco sheet cannot be achieved, which is not conducive to retaining the tobacco flavor and reducing the chipping of the tobacco sheet

The suitable temperature for high-grade smoke treatment is generally around 50°C, but the loosening rate of the smoke sheet at this time is poor and cannot meet the process requirements
