This one-step fluidized bed granulation dryer combines mixing,
granulation and drying in a single closed process, turning powder
into uniform multi-porous spherical particles without separate
stages. 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 PrinciplePowder is fluidized in a ring inside the raw material container,
preheated and mixed with purified heated air; a binder solution is
atomized in and the resulting agglomerates are dried continuously
until the binder solidifies, and the cycle repeats to build uniform
spherical particles.
- 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- One-step process integrating mixing, granulation and drying.
- Powder granulation improves flowability and reduces dust emissions.
- Powder granulation improves product solubility.
- Antistatic filter cloth supports safe operation.
- A pressure relief vent protects personnel in the event of an
explosion.
- Zero dead zones with quick loading and unloading and thorough
cleaning, meeting GMP standards.
Structural SchematicApplicationsSuitable for the granulation of granules, pills and powders; the
drying of pharm, pesticides, feed and fertilizers; and the drying
of catalysts.
- Granulation of granules, pills and powders.
- Drying of pharm, pesticides, feed and fertilizers.
- Drying of catalysts.
Customization NotesBecause mixing, granulation and drying happen in one vessel, the
powder is handled once and the finished spherical particles leave
ready for the next step. Batch capacity, construction material and
control configuration can be matched to your process; please share
your requirements for a tailored solution.
