To avoid channeling effects and to ensure true fluidization, vibration is required, so FBE is used Vibrating fluid bed dryers in the powder manufacturing unit. After introducing a fluid bed into the spray drying processing, FBE has recognized that there was a distinct difference in the structure of fluid bed treated powder compared with powder from a pneumatic conveying system. The fluid bed treated powder was distinctly coarser and free flowing. The reason for better flow ability was a partial agglomeration.
FBE manufactures Fluidized Bed dryer in 2,3 or 4 sections. In double section FBD 1st section is for heating and 2nd is for cooling. In Triple section FBD 1st sections are for heating and 2nd and 3rd are for cooling. In four sections FBD 1st and 2nd section for heating and 3rd and 4th are for cooling.
