Model 501 Fluid Bed Dryer
WHAT IS FLUID BED DRYING?
By forcing enough air through a bed of particles, the particle bed may assume a fluid-like state (resembling a boiling liquid). Heating the incoming air and managing air flow rate through the sample, the Model 501 Fluid Bed Dryer provides thorough mixing and maximum contact of solid with moving air.
The result - a process producing more even and much quicker drying than conventional methods
Delivering up to 2.5m3 per minute of air, the Model 501 Fluid Bed Dryer can break up wet samples and ensure vigorous mixing and rapid moisture removal.
Air separated particles prevents lumps and caking, both of which make other drying processes much slower.MILD High air flow rate gives:
HOMOGENEITY OF SAMPLE
Static drying methods leave evaporation residues at the sample surface giving a heterogeneous sample. Fluid Bed Drying achieves the opposite. Mixing during Fluid Bed Drying gives homogeneous samples, making an ideal method of representative sample preparation for subsequent material analyses.
Microprocessor control of air flow, inlet air temperature and drying period coupled with fluid bed action gives highly reproducible experiments and finished samples. After preliminary experiments, a known moisture content in the final sample (ideal for tablet forming) or removal of external (surface) moisture only, may be achieved. Drying times to required moisture content may be optimised and drying patterns studied to aid scale-up and plant design.
