Abstract: The traditional methods of KG-type tobacco redrying machine humidification are not very effective,nozzle gets easily blocked,and the temperature of moisture regaining parts exceeds standards,resulting steam and water waste.The new steam-water atomizing nozzle with adjusting cap can realize re-atomization,thus increasing the moisture regaining effect by over 4%.With this method,the temperature of moisture regaining parts can be controlled within 70 ℃,and the steam can be saved by over 30%.

Key words: tobacco redrying, mist spraying, balanced moisture, energy saving, atomizing nozzle with steam-water fluid, new humidification
