Air steam dryer

Air steam dryer

          Air Stream Dryer is drying equipment used to dry maize starch , potato starch and other starch material processed by wet method after dewatering process. It is also used to dry  heat sensitive powder or slice state material with fast speed.


          In the air steam dryer, high-speed hot air stream sustain raw material in the suspending state, then the material is dried. Since air stream speed is very high, and material is suspending in air stream, the heat transfer surface between air and solid is large, heat transfer rate is high, and drying time is short (usually within several seconds). It is peculiarly suitable for to dry heat sensitive material.

         Dry starch is discharged though centrifugal separator and star shape unloader. Exhaust air is let out into atmosphere.
