Econexis Engineering is one of the most trusted manufacturers and exporters of Agitated Thin Film Dryers (ATFDs) — the ultimate solution for handling high-viscosity, high-solid-content effluents and achieving Zero Liquid Discharge (ZLD). Our ATFD systems are designed for industries where conventional evaporation or drying systems fail due to scaling, fouling, or thermal sensitivity of products.
An Agitated Thin Film Dryer (ATFD) is a highly efficient evaporation and drying equipment used to concentrate and recover valuable solids from liquid effluents.
It works on the principle of creating a thin film of the feed liquid on a heated surface under controlled vacuum, while a high-speed rotor continuously agitates the film to enhance heat transfer and drying efficiency.
The system converts liquid or slurry feed into a dry solid or powder form, making it ideal for Zero Liquid Discharge (ZLD) applications.
Feed Introduction:
The concentrated effluent (from MEE or evaporator) is fed into the ATFD system.
Thin Film Formation:
The feed liquid forms a thin film on the inner wall of the heated cylinder due to the high-speed rotation of the agitator blades.
Evaporation:
The heat from the jacketed surface evaporates the water or solvent present in the feed under vacuum conditions. The generated vapors are condensed and collected separately.
Continuous Drying:
The continuous agitation prevents fouling and scaling while ensuring uniform drying. The solid residue moves downwards by gravity and scraper movement.
Discharge of Dry Product:
The dried material (powder, flakes, or crystals) is discharged at the bottom outlet, ready for collection or reuse.
High Thermal Efficiency: Uses indirect heating and vapor condensation recovery to save energy.
Robust Construction: Made from high-grade stainless steel (SS316L / Duplex Steel) for corrosion and wear resistance.
Uniform Drying: The rotating blades maintain a consistent thin film for even drying and no product degradation.
Low Power & Steam Consumption: Advanced design minimizes operational costs.
Automatic Controls: PLC/SCADA system for continuous monitoring and easy operation.
Compact & Modular Design: Easy to install and integrate with MEE or ZLD systems.
Zero Liquid Discharge (ZLD) Ready: Perfect for complete effluent treatment solutions.
