Abstract (en)
The process for preparing tobacco having bound catalytically active materials on its surface, consists in treating tobacco with catalytically active materials without the use of binding agents by the steps of distributing of catalytically active material on tobacco particles and pressing the catalytically active material on the tobacco particles. The treated tobacco is useful for manufacturing smokers' articles, particularly of cigarettes having a reduced amount of toxic components in the smoke. For carrying out the process, a device (1) comprising the following means is proposed: a) at least one conveyor belt (11, 12) for carrying the tobacco T b) a device (7) for supplying and distributing tobacco on the conveyor belt c) at least one device (9; 10) for supplying and distributing catalytically active material (C1, C2) on the tobacco on the conveyor belt d) at least one driving means for driving simultaneously the conveyor belt(s) (11, 12) and the devices (7, 9, 10) for supplying and distributing tobacco and catalytically active material. <IMAGE>
