Granulating Fluidized Bed Dryer 3-500kg/batch Powder Granulation Drying Machine

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.

Inside 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.

1. The powdered material is loaded into the raw material container.
2. Purified heated air is introduced, fluidizing the powder in a ring and mixing it with the air.
3. A binder solution is atomized and sprayed into the fluidized bed.
4. Several particles aggregate around the binder into binder-containing agglomerates.
5. The continuous hot air dries the agglomerates, evaporating the moisture and solidifying the binder.
6. The cycle repeats until uniform, multi-porous spherical particles are formed.

• 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.

Used 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.

The 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 tailored solution.
