Agitated Thin Film Dryer (ATFD)

An ATFD is a cutting-edge system designed to dry liquids, slurries, or pastes into solid powder or f lakes. It works by spreading the material into a thin layer on a heated surface, where it is continuously stirred for efficient drying. This makes it ideal for heat-sensitive materials and industries like pharmaceuticals, chemicals, and food processing.

How It Works:

  • Material Input: The liquid, slurry, or paste is fed into the dryer.
  • Thin Film Formation: The material is spread into a thin layer on a heated surface using rotating blades or wipers.
  • Agitation: The blades keep the material moving, preventing it from sticking and ensuring even drying.
  • Heat Transfer: The heated surface evaporates moisture from the thin film quickly and efficiently.
  • Dry Product Collection: The dried material is scraped off the surface and collected as powder or flakes.
  • Vapor Removal: The evaporated moisture is safely removed through a vapor outlet.

Benefits:

  • Efficient Drying: Rapid evaporation due to the thin film and continuous agitation.
  • Handles Heat-Sensitive Materials: Gentle drying without damaging delicate products.
  • Self-Cleaning: The rotating blades prevent buildup, reducing maintenance.
  • Energy-Saving: Optimized heat transfer minimizes energy consumption.
  • Compact Design: Takes up less space compared to other drying systems.
  • Versatile: Suitable for liquids, slurries, and pastes.

Applications:

  • Pharmaceuticals: Drying medicines and active ingredients.
  • Food Industry: Producing powders like instant coffee or soup mixes.
  • Chemicals: Drying dyes, pigments, and specialty chemicals.
  • Wastewater Treatment: Converting sludge into dry solids.

Why Choose an ATFD?

  • Advanced Agitation Technology: Ensures uniform drying and prevents sticking.
  • Customizable Designs: Tailored to meet specific industry needs.
  • Durable and Reliable: Built for long-term performance.
  • Eco-Friendly: Reduces waste and energy use.
