FLUID
BED DRYER
Fluid bed dryers are
manufactured in modular construction mainly consisting of main processing
(drying) unit and separate inlet air preparation unit and separate exhaust air
unit giving flexible and alternative installation option to the customers as
per requirement.
Fluid bed dryers are
most suitable for drying granules, crystalline, coarse or similar material in
pharmaceuticals, fine chemicals, dyes, foodstuff and allied industries.
Fluid bed processing
involves drying, agglomeration, granulation,
and coating of particulate materials. It is ideal for a wide range of
both heat sensitive and non-heat sensitive products. Uniform processing
conditions are achieved by passing hot air through a product layer under
controlled velocity conditions to create a fluidized state.
Using intimate
air-to-product contact, Drying is carried out by heated air supplied as main
the source for drying, as it is effectively introduced by steam heating which
gives high rates of heat exchange at high thermal efficiency while preventing
overheating of individual particles.
Fluid bed coating of
powders, granules, or tablets involves the spraying of a liquid on the
fluidized powder under strictly controlled conditions. It is ideal equipment
that is in conformity with the requirements of cGMP.
Ø CAPACITY:
·
Fluid
bed dryer/ Fluid bed processor comes with range of capacities as per our
customer’s requirement.
·
Capacity
range: - 5 Kg to 500 Kgs.
Ø OPERATION:
The wet material is loaded into the product container which is provided with
air distributor plate and Dutch weave mesh. Fresh air-to-product-contact is
filtered by means of 3-Way filtration process i.e. through coarse filter
, 5 micron filters and the HEPA Filter is heated by means of heater (steam or
electrical). This hot air then passes through the product container, creating
turbulence in the product and hence product moves up and down in the product
container. Due to this the heat transfer is quick and the product is dried fast
without appreciable heat loss. Filter bag prevents particle escaping from the
dryer.
Ø APPLICATION:
·
Suitable
for drying humidity from powder raw material in Pharmaceutical, foodstuff,
feed, chemical industries, etc
