摘要： In order to process cut tobacco so as to aerate and homogenize the same, a tobacco flow (12, 16) transits through several processing stations (18, 19, 20), in the area of which the tobacco is aerated with the aid of different processing elements while being conveyed. The tobacco flow or main flow is subdivided into several smaller partial flows during processing.

摘要： During the production process, tobacco has to undergo a preliminary treatment such as sifting, among other things, in order to eliminate foreign matters, ribs, etc. from the tobacco. According to the invention, the tobacco is delivered to a sifter (10) with the aid of air, and undesired components are eliminated therefrom in said sifter (10) in a counterflow treatment also by using air or sifting air. Separate currents are created for conveying the tobacco prior to the sifting process as well as for sifting the tobacco and conveying purposes following the sifting process, i.e. a delivery pipe (12) to the sifter (10) and a waste air pipe (15) from the sifter exclusively for conveying air, and a closed circuit comprising a discharge pipe (19) for sifted tobacco and a sifting air pipe (17) for the tobacco-free sifting air, thereby allowing different flow characteristics to be used for conveying and sifting.
