Agitated Thin Film Dryers
are used for continuous drying of
heat sensitive products with total
solvent recovery. We offer Vertical,
Horizontal or Combination dryers to
take feed in solution, slurry, paste
or wet powder form.
Features
Feeds can be processed without pretreatment
or dilution.
Indirect heating
and drying in absence of air. Particularly
effective for heat, light and oxygen
sensitive products.
Operating
pressure can be as low as 1 mbar
and operating temperature can be
as high as 350 °C (650 °F).
Organic solvent
bearing feeds can be successfully
handled with full solvent recovery.
Probably
the most energy efficient dryer
in the market. Thermal efficiency
can exceed 90%.
Fine powder
of uniform consistency can eliminate
pulverizes from downstream step.
Applications
Drying
Pharmaceuticals,
bulk drugs and intermediates.
Dyes, pigments
and intermediates.
Organic and
inorganic salts.
Recoveries
Solvent and
products from thick dry residues
Solvent and products from thick
dry residues.
DMSO from
salts.
Glycerine
from salts.
Organic and
salts from waste streams.
Rotor
Designs
We offer the
following four rotor designs to suit
specific application needs:
Zero Clearance
with hinged blades
Fixed Clearance
with screw elements.
Fixed Clearance
with hinged blades.
Zero
Clearance with hinged blades
In a dryer,
this design handles inorganic salts
with organic residues and slurry.
Suitable
for pressures up to 1 mbar.
Fixed
Clearance with screw elements
Mainly used
in horizontal dryers to handle sticky
pastes.
Suitable
up to 1 mbar pressure.
Fixed
Clearance with hinged blades
Special design
for vertical dryers.
Handles solutions
and slurries where the end product
is dry powder.
Feeds can be processed without pretreatment
or dilution.
