process overview

Agitated Thin Film Dryers (ATFD)

Ideal for converting viscous or high-solid-content materials into dry solids in a continuous process. Feed spread into thin film on heated surface with rotor providing continuous agitation for high heat transfer. Often operated under vacuum. Cornerstone of ZLD.

Agitated Nutsche Filter Dryers (ANFD)

All-in-one solution combining filtration, washing, and drying in single contained unit. Highly advantageous in cGMP pharmaceutical manufacturing, minimizing operator exposure and preventing contamination.

Rotary Vacuum Paddle Dryers (RVPD)

Batch-processing systems for drying moist slurries and pastes, especially heat- and solvent-sensitive APIs. Operates under deep vacuum for gentle, low-temperature drying. Paddles ensure uniform mixing.

Key Performance Metrics

Proven results that drive operational excellence

ATFD Performance

  • Final moisture: < 5% to 10%
  • > 95% solids recovery in ZLD
  • 25 - 30 % reduction in the steam consumption
  • 30% higher thermal efficiency than conventional dryers
  • Residence time: 10-120 seconds

RVPD Performance

  • Final moisture: ppm levels (critical for APIs)
  • 30 - 50% reduction in drying cycle times vs. atmospheric dryers

 

 

 

ANFD Performance

  • Low Loss on Drying (LOD)
  • Low residual solvent meeting ICH Q3C limits
