About Agitated Thin Film Dryer

An Industrial Agitated Thin Film Dryer (ATFD) is a continuous drying system specially designed for handling heat-sensitive products under vacuum conditions while enabling efficient solvent recovery. The equipment operates by spreading the feed material into a thin film over a heated surface using rotating agitator blades, resulting in rapid heat transfer and effective evaporation.

ATFD technology utilizes indirect heating and controlled drying conditions, making it highly suitable for products that are sensitive to heat, oxygen, or prolonged exposure to elevated temperatures. Its vacuum-based operation enhances drying efficiency, reduces thermal degradation, and improves product quality.

Also known as a Thin Film Evaporator (TFE), the system is widely used to convert slurry, solution, or paste-like feed materials into free-flowing powder or dry solids. Agitated Thin Film Dryers are extensively employed in pharmaceutical, chemical, food processing, specialty chemical, and allied industries where conventional drying and evaporation methods may not be effective.

Applications

• Pharmaceutical Industry: Drying API slurries, herbal extracts, and intermediates.
• Chemical Industry: Drying polymers, resins, pigments, and dyes.
• Food Industry: Drying malt extracts, proteins, and fruit/vegetable purees.
• Wastewater Treatment: Recovering solids from effluents and sludges.

How Agitated Thin Film Dryer works

• Feed Material: The wet feed (liquid, paste, or slurry) is introduced at the top of a vertical or horizontal cylindrical drying chamber.
• Thin Film Formation: A rotating agitator with specially designed blades spreads the feed into a thin film on the heated surface.
• Evaporation: Heat is applied to the cylindrical surface, causing rapid evaporation of moisture from the thin film.
• Separation: The vapors are collected and condensed, while the dry product (powder, flakes, or solids) is discharged at the bottom.

FAQs

• 1. What is an Agitated Thin Film Dryer (ATFD)?

  An Agitated Thin Film Dryer (ATFD) is a continuous drying system designed for processing viscous liquids, slurries, and heat-sensitive materials. It utilizes a rotating agitator to spread the feed into a thin film over a heated surface, enabling rapid evaporation, efficient drying, and high product quality under controlled conditions.

• 2. Which industries use Agitated Thin Film Dryers?

  Agitated Thin Film Dryers are widely used in pharmaceutical, chemical, food processing, petrochemical, specialty chemical, and wastewater treatment industries. They are particularly suitable for applications involving heat-sensitive, sticky, or high-viscosity products that require efficient drying and solvent recovery.

• 3. What is the difference between an Agitated Thin Film Dryer and a Thin Film Evaporator?

  Both systems operate on the thin film principle; however, a Thin Film Evaporator is primarily used for concentration and solvent evaporation, while an Agitated Thin Film Dryer is designed to achieve higher levels of moisture removal and produce dry solids or free-flowing powder from slurry or solution-based feed materials.

• 4. What are the advantages of using an Agitated Thin Film Dryer?

  Agitated Thin Film Dryers offer several advantages for industrial drying applications, including:

  • High heat transfer efficiency and reduced drying time
  • Excellent performance under vacuum conditions
  • Suitable for heat-sensitive and oxygen-sensitive products
  • Efficient solvent recovery and minimal product degradation
  • Continuous operation with high throughput capacity
  • Low maintenance requirements and reliable performance
