This drying fluidized bed granulation dryer removes moisture from
granules and powders using purified heated air in a fluidized bed.
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 PrincipleThe powdered material is fluidized in a ring and mixed with
purified heated air; after a binder solution is atomized in, the
hot air continuously evaporates the moisture in the agglomerates
and solidifies the binder, and the cycle repeats to form dry,
uniform, multi-porous 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- Continuous hot-air drying of the fluidized agglomerates.
- Dries pharm, pesticides, feed, fertilizers and catalysts.
- One-step process integrating mixing, granulation and drying.
- Improves flowability and reduces dust emissions.
- Antistatic filter cloth and a pressure relief vent for safe
operation.
- Zero dead zones with thorough cleaning, meeting GMP standards.
Structural SchematicApplicationsSuited to the drying of pharm, pesticides, feed and fertilizers and
the drying of catalysts, as well as the granulation of granules,
pills and powders.
- Granulation of granules, pills and powders.
- Drying of pharm, pesticides, feed and fertilizers.
- Drying of catalysts.
Customization NotesDrying and granulation run together in the fluid bed, so the
moisture is driven off as the agglomerates form rather than in a
separate step. Batch capacity, construction material and control
configuration can be matched to your process; please share your
requirements for a tailored solution.
