Tobacco shred immersion method and device

Abstract

The invention relates to a tobacco shred immersion method and a device; the method comprises: (1) the tobacco shred is arranged in a pre-heating immersion device and then vacuumizing is carried out; (2) swelling agent with liquid state is sprayed on the tobacco shred; (3) swelling agent with gas state is filled in the immersion device; (4) immersion is carried out. The immersion device provided by the invention comprises a tank body, an upper tank cover, a lower tank cover and a hydraulic pressure opening device, a spraying device is arranged in the upper tank cover, wherein the tank body is provided with two layers of sleeves, a screen cloth is formed on the inner wall of the inner layer sleeve, and the pore diameter of the screen cloth is 1.5mm. The invention has simple structure and convenient operation, can achieve good immersion effect to the tobacco shred and can realize continuous immersion of the tobacco shred.

Description

Technical field [0001] The invention relates to the field of tobacco production and manufacturing, in particular to a method and a device for impregnating shredded tobacco in the production and manufacturing process of cigarettes. Background technique [0002] At present, in the world's cigarette manufacturing process, in order to improve the quality of cigarettes, a variety of techniques are adopted to improve the quality of shredded tobacco. Among them, to reduce the amount of tar in cigarette smoke, improve the quality of smoking food, make cigarettes burn evenly and improve the filling capacity of shredded cigarettes. , Manufacturers with certain technical capabilities use tobacco expansion technology to achieve the above-mentioned purpose. In the tobacco expansion technology, the more mature and popular technologies in the world at this stage are the carbon dioxide tobacco expansion technology, the freon tobacco expansion technology, and the nitrogen tobacco expansion techno...

AI Technical Summary

Problems solved by technology

But this method has flaws: due to the input of liquid CO 2 impregnated tobacco, so the residual CO on the impregnated tobacco 2 (dry ice) is more, generally more than 10% of the shredded tobacco

The design of the impregnation device is very complicated and the manufacturing cost is high

And this patent does not propose a better improvement on the problem of the spraying device

[0006] Although some improvements have been made to the impregnation device and the impregnation method in the prior art, the above method still cannot completely reduce the crushing rate of the shredded tobacco and realize continuous impregnation.
