Tobacco shred expansion method and tobacco shred storage device

Abstract

The invention discloses a tobacco shred expansion method and a tobacco shred storage device, and the method comprises the following steps: moisture regaining: carrying out pre-treatment on raw materials, and then carrying out leaf moistening treatment; the wet leaves are shredded and then screened for the second time, and then the tobacco shreds are subjected to pressure reduction treatment in a container. And storing: reducing the pressure to be close to the standard atmospheric pressure under the condition of not destroying the cell micropore structure of the tobacco shreds. And expansion: injecting water vapor or other heated inert media into the container, and rapidly increasing the temperature in the container, so that the tobacco shreds are expanded and shaped. The pressure in the container is reduced again, the tobacco shreds are subjected to vacuum treatment and then subjected to leaf moistening treatment, and the situation that the breakage rate is increased due to the fact that the tobacco shreds are too crisp is avoided. And screening: introducing the atmosphere to increase the pressure in the container to standard atmospheric pressure, carrying out third screening, and boxing and warehousing after winnowing. The temperature of the expanded tobacco shreds during moisture regaining is guaranteed, the flexibility of the expanded tobacco shreds is improved, and breakage of the tobacco shreds during moisture regaining is reduced.

Description

technical field [0001] The invention relates to the technical field of shredded tobacco processing, and more particularly, to a method and a device for expanding shredded tobacco. Background technique [0002] The puffed cut tobacco is looser, crispier and less resistant to damage than that of the traditional silk making line. The inherent characteristics of these puffed cut tobacco require more flexible processing of the puffed cut tobacco. The screening method of the cut tobacco in the prior art is not thorough enough, thereby leading to an increase in the shredded rate of the finished expanded cut tobacco. [0003] The existing silk storage cabinet after expansion also completely copied the traditional silk production line, and did not fully consider the personality of the expanded silk. The existing finished product storage cabinet has a small bottom area and a large vertical height. The drop between the cloth truck and the bottom belt of the storage cabinet was more t...

AI Technical Summary

Problems solved by technology

When discharging, the drop of shredded tobacco is as high as 2 meters, which will form the third crushing

In addition, since the middle and lower layers of expanded filaments are relatively densely pressed, the pulling roller needs a lot of force to remove the shredded tobacco. At this time, the fourth crushing of the expanded filaments will be formed.

This leads to a high shredded shred rate, which affects the shredded shred rate of finished tobacco products and reduces the quality of shredded tobacco
