Abstract:
The present invention provides a method for drying wet powder by using a fluidized bed dryer. The drying method includes the steps of: (S1) dividing a lower gas chamber into two or more sections, in a fluidized bed dryer including a gas distribution plate provided with multiple holes, and an upper drying chamber and the lower gas chamber divided by the gas distribution plate; (S2) raising the internal temperature of the upper drying chamber and then supplying wet powder through an inlet port provided at a side of the upper drying chamber; and (S3) supplying fluidized gas at different flow velocities into the two or more sections of the lower gas chamber by using an external blower and introducing the fluidized gas having the different flow velocities into corresponding areas of the upper drying chamber through the gas distribution plate to perform drying of the wet powder.
