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.
1. Efficient Drying: ATFDs offer efficient drying of highly viscous liquids and slurries by spreading the material into a thin film, ensuring rapid heat transfer and quick evaporation of moisture. 2. Compact Design: ATFDs have a compact footprint, requiring less space compared to other drying equipment, making them suitable for industries with limited floor space.
3. Handles High Viscosity: Unlike other dryers, ATFDs can efficiently process highly viscous liquids and slurries, ensuring continuous operation without blockages or inefficiencies.
4. Zero Liquid Discharge (ZLD) Applications: ATFDs are crucial in ZLD systems, as they convert liquid waste into dry solids, facilitating easy disposal and contributing to environmentally sustainable operations.
5. Low Maintenance: The design of ATFDs minimizes fouling and scaling, reducing the need for frequent cleaning and maintenance, and ensuring longer operational uptime. 6. Product Recovery: ATFDs allow industries to recover valuable products from wastewater or by products, increasing resource recovery and reducing waste disposal costs.
