One platform, five functions: mixing, granulation, micro-pellet coating, powder layering and drying — in four sizes from the MINI 0.2 (batches from 30 g) through DPL-Ⅱ, DPL-5 to DPL-20 production, with top-spray, Wurster bottom-spray and side-spray configurations sharing one air-handling base, inlet air up to 120 ℃, PLC controlled.
Highlights
Top spray granulation-drying, Wurster bottom-spray coating, tangential side-spray pelletizing — change the container, keep the base.
PLC records inlet/outlet temperature, spray rate, atomization pressure, fluidizing volume and product temperature per batch.
Standard guns come from the Benelabo spray series — spares and upgrades stay open, never locked.
MINI 0.2 (750×630×850 mm) through DPL-20 with transferable parameter logic, de-risked by sampling.
Applications
- Granulation and drying of pharmaceutical powders
- Wurster film coating of pellets and particles
- Tangential pelletizing and powder layering
- Functional coatings: moisture protection, taste masking, sustained release

FAQ
What batch sizes does the mini fluid bed support?
MINI 0.2 runs 0.05–0.25 kg per batch by top spray and 0.03–0.2 kg by Wurster bottom spray, with the DPL series scaling to production.
Can one fluid bed do granulation, coating and drying?
Yes — switching the product container and spray set moves between top-spray granulation, Wurster coating and tangential pelletizing on the same base.
Can it run hot melt coating?
Yes — couple the hot melt spray system to mini, pilot or production units for solvent-free functional films.
