DRYING SYSTEM COMBINING A FLUIDIZED BED DRYING AND SWIRLING AIR FLOW DRYING

摘要

The present invention relates to a drying system combining fluidized bed drying and swirling air flow drying, comprising a combined drying cylinder (100) including a fluidized bed for regularly drying an object to be dried to a set percentage of moisture content by the hot air; and a swirling air flow layer (20) for increasing a stay time of the object to be dried until the percentage of moisture content in the object is dried to a target percentage and discharging the object; a cyclone (200) for receiving the object from the combined drying cylinder, discharging the object downward, and discharging the hot air via a discharge pipe (210) connected to a center; and a hot air supply part (300) receiving a part of the hot air discharged via the discharge pipe of the cyclone, heating the received hot air, and supplying the heated air for the combined drying cylinder.
