Controlled drying after wet granulation
Fluid Bed Dryer
Fluid bed dryer for pharmaceutical wet granules with drying, discharge, milling and transfer integration for OSD production lines.
Short Answer
A fluid bed dryer dries wet granules using controlled process air before discharge to milling, sieving, blending or final transfer steps.

Quotation input
What Information Is Needed For Quotation
A clearer URS and layout package helps the engineering team confirm equipment scope, capacity assumptions, containment expectations and documentation needs.
Product name, powder properties, bulk density, particle size range and flowability notes.
Required capacity per batch or per hour, target transfer distance and elevation.
Process layout, room classification expectations and upstream/downstream equipment interfaces.
Containment, dust extraction, cleaning, material contact and documentation expectations.
Utilities, control preference, automation scope and FAT/SAT/IQ/OQ support requirements.

FAQ
Frequently Asked Questions
What determines fluid bed dryer capacity?+
Capacity depends on wet batch load, moisture content, drying target, air volume, temperature limits, product behavior and cleaning cycle.
Can the dryer discharge directly to a cone mill?+
Yes. Direct discharge to a cone mill or transfer system can be considered if layout, height and cleaning access allow it.
Is documentation support available for pharmaceutical projects?+
Documentation support can be included according to project scope, including drawings, material certificates, FAT/SAT records and IQ/OQ support if required.
