WFE Series Rotating‑Scraper Vacuum Thin‑Film Evaporator for High‑Viscosity Crystallizing Media

The WFE series high-efficiency rotating scraper thin film evaporator is a new type of high-efficiency evaporator that forces the feed into a thin film by means of rotating scrapers and performs falling-film evaporation under vacuum. It features high heat transfer coefficient, high evaporation intensity, short residence time and large operating flexibility, and is especially suitable for evaporation concentration, degassing, desolvation, distillation and purification of heat-sensitive materials, high-viscosity materials and easily crystallized materials containing particles. Therefore, it is widely used in chemical, petrochemical, pharmaceutical, pesticide, daily chemical, food, fine chemical and other industries.

• High heat transfer coefficient and evaporation intensity
• Anti-crystallization design: rotating scrapers continuously wipe the heating surface to prevent crystal build-up
• Short residence time with large operating flexibility
• Handles high-viscosity and easily crystallized materials containing particles
• Six scraper types available: Sliding, Flexible, Hinge, Fixed, Roller, Spiral
• Large model range from WFE-12 to WFE-100 (heating area 12-100 m²)
