At our core, we engineer solutions for the most demanding separation processes. Our Wiped Film Evaporator (WFE) series is the culmination of advanced engineering and a deep understanding of the challenges in handling sensitive, viscous, and fouling-prone materials. Designed for maximum efficiency and product protection, this system is the definitive choice for industries where quality and yield are paramount.
How Our Wiped Film Evaporator Works
The principle is both elegant and highly effective. The feed material is distributed evenly onto the heated cylinder wall. Rotating wipers then spread the liquid into an extremely thin, turbulent film. This "wiped" action is the heart of a Wiped Film Evaporator, ensuring rapid heat transfer and a very short product residence time.
Volatile components evaporate instantly under vacuum, travel to an integrated condenser, and are collected as the distillate. The concentrated product is efficiently conveyed to the bottom discharge. This precise mechanical control over the liquid film prevents thermal degradation, making our Wiped Film Evaporator ideal for heat-sensitive compounds.
Key Features & Technical Advantages
- Superior Product Protection: Operates at low evaporation temperatures (45°C - 60°C) under high vacuum (0.03 - 0.08 MPa), safeguarding thermolabile substances.
- Unmatched Efficiency: A large condensing area ensures optimal vapor recovery, while a compact heat exchange surface delivers remarkable throughput.
- Handles Challenging Materials: Excellently suited for high-viscosity products and substances that tend to foam or foul, thanks to the continuous scraping mechanism.
- Flexible & Scalable: Available in multiple models (GBN-0.2 to GBN-5) with heating surfaces from 0.2 m² to 5 m², allowing for perfect scaling from R&D to full production.
- Robust Construction: Manufactured from high-grade stainless steel (304/316) for corrosion resistance, durability, and compliance with stringent hygiene standards.
- Advanced Control: Features a Siemens PLC-based control system for precise automation, repeatable results, and simplified operation.
