The Agitated Thin Film Dryer (ATFD) is an advanced drying technology used to concentrate and dry highly viscous liquids, slurries, and waste streams by creating a thin film of the material on a heated surface. The agitation helps ensure efficient heat transfer and rapid evaporation, leaving behind dry solids.

ATFDs are ideal for industries dealing with heat-sensitive materials, as they allow for gentle yet effective drying without product degradation. ATFDs are widely used in sectors like pharmaceuticals, Textile, Tannery, chemicals, and food processing, automobile to recover valuable solids from wastewater, reduce moisture content in products, and facilitate safe disposal of waste. This technology plays a key role in achieving Zero Liquid Discharge (ZLD) by converting liquid waste into dry, manageable forms.

Advantages

• Continuous operation
• High heat-transfer efficiency
• Short residence time (good for heat-sensitive products)
• Can handle highly viscous materials
• Produces uniform dry product
• Lower risk of product degradation compared with many conventional dryers
