Tobacco piece loosening and conditioning system

Abstract

The invention discloses a tobacco piece loosening and conditioning system. The system comprises a vertical splitting machine, a tunnel type preheating conditioning loosening machine and a percolation type hot-air loosening conditioning machine which are arranged in accordance with a pipeline method in turn. A constant flow control system is arranged between the tunnel type preheating conditioningloosening machine and the percolation type hot-air loosening conditioning machine. A turning and slow releasing device is arranged between the vertical splitting machine and the tunnel type preheating conditioning loosening machine. The tunnel type preheating conditioning loosening machine is equipped with a bending delivery tunnel. The tobacco piece loosening and conditioning system has a combination of the tunnel type preheating conditioning loosening machine and the percolation type hot-air loosening conditioning machine, causes more even heating, improves loosening rate of tobacco flakes and reduces fragment generation ratio. The tobacco piece can be loosened and conditioned under low strength condition, and the raw materials of the tobacco can be subject to maximal flexible looseningto keep original fragrant of the tobacco, and realize coordination of sensor quality and material loosening.

Description

technical field [0001] The invention relates to a device for loosening and dampening cigarette blocks in the tobacco industry. Background technique [0002] Tobacco raw materials are pressed into blocks for storage and transportation after threshing and redrying. When making cigarettes, the tobacco blocks need to be restored into loose tobacco leaves. The large cigarette blocks in the boxed cigarette packs are first cut into small cigarette blocks by a slicer, and then become loose tobacco leaves through a loosening and dampening device. [0003] 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 (t...

AI Technical Summary

Problems solved by technology

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.

[0005] (2) The smoke sheet is heated unevenly in the process of loosening and regaining moisture

One is loosening and rehydrating in the drum-type tobacco leaf rehydrating machine. After the cigarette block enters the loosening and rehydrating drum, there will be a small part of the tobacco leaves in the center of the drum that cannot be effectively dispersed, and this part of the tobacco leaves cannot be evenly heated during the loosening and rehydrating process.

The second is that the change of steam flow makes the scattered smoke sheet heated unevenly

[0006] (3) The existing loose moisture regain equipment has a high breakage rate

One is that after sliced ​​by the slicer, the height difference between the output height of the cigarette block and the downstream connecting equipment is large, and the sliced ​​cigarette block falls on the downstream equipment due to its own weight. Since the tobacco leaves are relatively dry at this time, it is easy to break

The second is that when the cigarette block enters the drum-type tobacco leaf moistening 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. Causes greater shredding of tobacco leaves, so the traditional loose rehydration method has a high shredding rate of tobacco leaves in the drum type tobacco leaf rehydration machine
