The Aeromatic-Fielder™ FlexStream™ (patent
pending) Fluid Bed is a new Multi-Purpose Processor from GEA
Pharma Systems that uses proven fluid bed technology to achieve granulation,
drying and pellet coating (or tablet coating) in ONE processor.
Advantages of the FlexStream™ Fluid Bed:
-
Only ONE product
container for all unit operations
Fluid Bed Granulator - Fluid Bed Dryer - Fluid Bed Coater, ALL
in 1 container
-
Only one design/height for all unit operations
Reduced building envelope in both height and footprint
-
Built in linear scale up
-
Ready for fully contained
loading and unloading
-
Superior product
homogeneity both for LOD and PSD
-
Enabling PAT:
in-line measurement of particle growth
FlexStream™ has spray nozzles mounted in the side walls
of the processor. Although this is the optimal nozzle position from a
processing point of view, it still carries the risk of uncontrolled over
wetting the particles that get sucked into the area of very high humidity just
in front of the nozzle tips.
Therefore in FlexStream™ particles are
pneumatically driven away from this zone by a protective air stream taken from
the normal process air. No compressed air is required for this set-up which
results in higher yields as fewer particles are destroyed.
The system
is also more energy efficient than systems using compressed air as no third air
supply is required.
The FlexStream™ concept has the additional
advantage that no mechanical adjustment is necessary to switch between using
the equipment as a dryer, a granulator or a coater.
Impressive test
data prove that, in addition to these commercial benefits, FlexStream™ gives
superior product quality when compared with conventional top-spray granulation
or wurster coating.
