A process and apparatus for adding tobacco powder to tobacco sheet produced by paper-making process- Tobacco powder is added in four processing points comprised pipeline place from steady slurry box to flowing slurry box, long-web of paper machine, any place from vacuum couch roller to one presser, and coating of paper machine. The ratio of adding tobacco powder is 5-30% by weight. The above process of the invention for adding tobacco powder to tobacco sheet produced by paper-making process can increase packing character of tobacco sheet. The problem of bad aesthetic quality and thicker woody smell of tobacco sheet in tobacco papermaking process is solved. Furthermore, the problem is solved that tobacco powder source of 2rnm-100particle is abandoned in cigarette processing, therefore, source is saved, and cost is reduced.
