| Zusammenfassung: | The invention relates to a continuous drying method and a continuous drying device by conveying hot air spirally. The device consists of an air inlet tube (1), an air distribution chamber (2), a spiral conveyor (3), an air chamber (4), an exhausting tube (5), a feed hopper (12), a discharge hopper (13) and an air intake device of the spiral conveyor (3). The device is characterized in that: a certain air intake device ensures that hot air is injected into the spiral conveyor (3) from the distribution chamber (2); two ends of the spiral conveyor (3) are provided with the feed hopper (12) and the discharge hopper (13), and an opening facing upwards is formed in the center of the spiral conveyor (3); the air chamber (4) of which both the volume and projected area on the ground are greater than those of the spiral conveyor (3) is connected to the opening; and the exhausting tube (5) is arranged above the air chamber (4). |
