This granulating fluidized bed dryer builds granules directly from
powder and dries them in the same vessel. Mixing, granulation and
drying run in one closed vessel, so the powder is charged once and
leaves as dry, free-flowing, multi-porous spherical granules ready
for the next process step.

Working PrincipleInside the raw material container the powder is fluidized in a ring
and mixed with purified heated air; a binder solution is atomized
and sprayed in, aggregating several particles, and the hot air
dries the agglomerates so the binder solidifies into uniform
spherical granules.
- The powdered material is loaded into the raw material container.
- Purified heated air is introduced, fluidizing the powder in a ring
and mixing it with the air.
- A binder solution is atomized and sprayed into the fluidized bed.
- Several particles aggregate around the binder into
binder-containing agglomerates.
- The continuous hot air dries the agglomerates, evaporating the
moisture and solidifying the binder.
- The cycle repeats until uniform, multi-porous spherical particles
are formed.
Key Features- Forms binder-containing agglomerates from fluidized powder.
- Repeats the cycle continuously to build uniform, multi-porous
spherical particles.
- Improves flowability and reduces dust emissions.
- Improves the solubility of the granulated product.
- Antistatic filter cloth and a pressure relief vent for safe
operation.
- Zero dead zones with quick loading and unloading for GMP cleaning.
Structural SchematicApplicationsUsed for the granulation of granules, pills and powders and for
drying pharm, pesticides, feed, fertilizers and catalysts.
- Granulation of granules, pills and powders.
- Drying of pharm, pesticides, feed and fertilizers.
- Drying of catalysts.
Customization NotesThe granulating action and the drying action share one air stream,
so the granules are formed and dried without being transferred.
Batch capacity, construction material and control configuration can
be matched to your process; please share your requirements for a
