Product Description

A vertical agitated thin film dryer (ATFD-V) isa type of dryer that converts concentrated materials into solids or semi-solids.

• Feeding:  The feed material is pumped to a heat exchanger
• Agitating: A high-speed rotor inside the dryer agitates the feed material, which is spread into a thin film on the heated wall
• Heating: The shell of the dryer is heated by steam
• Evaporating: The volatile components evaporate from the product layer
• Discharging: The final solid product is discharged by gravity at the bottom of the dryer

Here are some advantages of using an ATFD-V:

• Energy efficient: ATFD-Vs can have a thermal efficiency of over 90%
• Heat transfer: The intense agitation allows for fast heat transfer
• Handles high viscosity fluids: ATFD-Vs can handle fluids with high viscosity
• Low pressure and high vacuum: ATFD-Vs can operate at low pressure and high vacuum

FEATURES

• Residence time of a few seconds, well suited for heat sensitive products
• Can be used as Vacuum Dryer for reduced temperature, operating pressure as low as 1mbar
• Indirect heating, particularly effective for oxygen sensitive products
• Air free operation, full recovery of organic solvents
• Dust free powder of relatively higher bulk density
• Powder of uniform consistency, eliminating downstream pulverize

• APPLICATIONS

  • Pharmaceuticals, bulk drugs and intermediates
  • Water soluble proteins
  • Dyes, pigments and intermediates
  • Organic and inorganic salts
  • Clean room applications
  • Possibility of getting amorphous powders
  • Solvents and products from residue
  • DMSO from salts
  • Glycerin from salts and residue
  • Organic solvents or products from salt bearing waste streams
