摘要： A new highly-efficient energy-saving threshing air separation process and device, used to perform air separation on tobacco flakes and tobacco stalks. The process sequentially comprises the following steps: a scraping plate feeding machine (2), a bin type feeding machine (3), a proportional distributor (4), a first-level threshing machine set (5), a conveying belt (6), a first-level air separation machine set (7), a stalky leaf conveying belt (10), a second-level threshing machine set (11), a conveying belt (12-14), a second-level air separation machine set (15), a stalky leaf conveying belt (19), a third-level threshing machine set (20), a conveying belt (21-23), a third-level air separation machine set (24), a stalky leaf conveying belt (28), a fourth-level threshing machine set (29), a conveying belt (30), and a fourth-level air separation machine set (31). The first-level air separation machine set (7) is provided with an air pressure type double-bin air separator (9) that only selects qualified tobacco flakes through air separation; and the second-level, third-level air, and fourth-level air separation machine sets (15, 24, 31) are provided with air pressure type three-bin air separators (17, 26) that can select qualified tobacco flakes and tobacco stalks through air separation.
