Horizontal Thin Film Evaporator

The Horizontal Thin Film Evaporator (HTFE) is an advanced system designed to evaporate solutions efficiently by forming a thin, agitated film. It incorporates a precision-engineered jacketed shell and a centrally located high-speed rotor equipped with closely fitting blades. This setup ensures uniform
heat transfer and optimized evaporation performance.


How It Works:

  1. Feed Input: The feed material, whether in the form of solution, slurry, or wet cake, is
    introduced into the evaporator.
  2. Thin Film Formation: The rotor spreads the feed into a thin film along the inner surface of
    the shell, enhancing heat exposure.
  3. Intense Agitation: The rotor blades create high-speed agitation, ensuring uniform heat
    transfer and preventing fouling.
  4. Evaporation Process: As the film is heated, it transitions through phases, transforming from
    slurry to paste, and finally to vapor.
  5. Vapor-Liquid Separation: The remaining liquid and vapor are separated efficiently, ensuring
    the desired outcome for further use or processing.


Applications:

  • Pharmaceuticals: Evaporation of solvents and concentration of active ingredients.
  • Food Processing: Production of concentrates from liquid food products.
  • Chemical Industry: Evaporation of chemical solutions and heat-sensitive compounds.
  • Environmental Engineering: Efficient treatment of industrial effluents.


Key Benefits:

  • High Efficiency: Uniform thin film enables rapid heat transfer and evaporation.
  • Gentle Process: Suitable for heat-sensitive and viscous materials.
  • Versatility: Handles a wide variety of feed forms and liquid compositions.
  • Compact Design: Space-saving construction with high throughput.

Process Flow for Horizontal Thin Film Evaporator (HTFE) System

Feed Input → (Solution, slurry, or wet cake is introduced into the evaporator)

Rotor Mechanism → (Spreads the feed into a thin film along the inner shell
surface)

Intense Agitation → (High-speed rotor blades ensure uniform heat transfer and
prevent fouling)

Evaporation Process → (Heat gradually transforms the feed from slurry to paste,
and then to vapor)

Vapor-Liquid Separator → (Efficiently separates the remaining liquid and vapor)

Final Collection Tank → (Stores the concentrated liquid for further processing)

Vapor Outlet → (Separated vapor is removed for condensation or reuse)
