ABSTRACT OF THE DISCLOSURE A process for converting cigarette tobacco winnowings into usable form for cigarette making, comprises crushing the winnowings, which have a moisture content compatible with cigarette making, effecting a first sieving operation on the resulting crushed winnowings, and effecting a second sieving operation on the smaller fraction resulting from the first sieving operation to remove particles unsuitable for direct use. Any larger fraction resulting from the first sieving operation may be subjected to cutting and there- after a third sieving operation. The apparatus comprises crushing rollers to which the winnowings are fed and a sieve arranged to receive the crushed winnow- ings from the crusher. A second sieve is also provided to separate the tobacco usable for cigarette making from tobacco dust. The apparatus may also include a cutter for receiving and cutting the larger fraction of the sieved crushed winnowings. The three operations of crushing, sieving and cutting are all advantageously performed on the tobacco at cigarette maker moisture. It is also performed at ambient pressure and tempera- ture, thereby greatly reducing capital costs over processes requiring heating, cooling, pressurizing or moisture variation.
