Fluid Bed Dryer


Spray Granulator

Drying: The high drying efficiency is because the powder or granules are fluidized in the drying chamber and the container is using a turbo blower, the hot air passed through the powder or granules from bottom to the top of drying chamber to remove the humidity.

Granulation: Spray atomized binder or active ingredients on the suspension powder by spray guns to formm the uniformity granules.


  1. Drying: The better time saving of YENCHEN's FBD to dry powder or granules is 10-20 times faster than the conventional oven.
  2. Granulation: The better fluidity and solubility of the granules after spraying the binder or active ingredients from the top to the fluidized powder.
