Glass Falling Film Evaporator

A falling film evaporator (FFE) uses gravity to create a thin liquid layer inside heated vertical tubes. As the liquid flows down, it’s partially vaporized by heat. This separates the concentrated liquid (collected at the bottom) from the vapor.

Product Description

  • Modular & Scalable Configuration
    Standardized modular design enables flexible combinations to accommodate varying process scales and spatial constraints.
  • Continuous Feed & Discharge System
    Fully automated operation significantly reduces labor costs, shortens production cycles, and enhances throughput efficiency.
  • Integrated Process Adaptability
    Pre-engineered thermal transfer, separation, and control systems handle viscous, heat-sensitive, and crystallizing materials across diverse applications.
  • High-Vacuum Magnetic Sealing
    Leak-free magnetic drive maintains vacuum ≤5 Pa for stable and efficient evaporation.
  • 316L Stainless Steel Construction
    Medical-grade 316L evaporation units deliver superior corrosion resistance and thermal conductivity (K-value ≥1500 W/m²·K), complying with GMP standards.
  • Quick-Disassembly Maintenance
    Pressure-resistant sight glasses and ISO-standard quick-clamp fittings enable CIP (Cleaning-in-Place), cutting maintenance time by 50%.
  • Optional Entrainment Separator
    High-efficiency cyclone separator reduces material entrainment loss to ≤0.1%, maximizing product yield.
  • Multi-Stage Process Integration
    Seamlessly interfaces with short-path molecular distillation or fractionation towers for integrated evaporation-purification solutions.\
