ABSTRACT
Seed cleaners, separators, treaters and bagging machinery must be used in a specific sequence: the seed are first generally “cleaned”, using scalpers and air-screen cleaners to remove most of the larger, smaller, and/or lighter undesirable materials. Then the more generally-used separators, length separator and/or gravity separator, are used. If undesirable materials are still in the seed lot, special separators using a specific physical difference are used. Then, the seed may be treated. Finally, the seed are bagged or packaged in the most market-suited package (Figure 49.1).
