Abstract

The addition of mixing technology can effectively improve the phenomenon of agglomeration in the local area of finished tobacco billet due to the uneven distribution of reconstituted tobacco during the packing process. In this paper, a numerical simulation model of reconstituted tobacco mixing process was established by using the discrete element method (DEM) to study the effects of horizontal and vertical velocity of the mixing bar on the distribution of reconstituted tobacco in the box. The results show that the distribution uniformity of reconstituted tobacco in the bottom of the mixing box increase with the increasing of horizontal reciprocating velocity. When the vertical mixing velocity matches with the accumulation speed of reconstituted tobacco, the mixing effect is better. Under the simulation conditions, the uniformity of reconstituted tobacco distribution at the bottom of the box achieve the optimal, when the value of horizontal reciprocating velocity and vertical velocity of the mixing bar is 1.1m/s and 0.8mm/s, respectively.
