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
