Scraped Film Evaporator: The Expert in High-Viscosity and Heat-Sensitive Material Separation
The scraped film evaporator (WFE) is a new type of high-efficiency evaporation and distillation equipment specifically designed for processing high-viscosity, heat-sensitive, and easily crystallizing materials. This equipment uses mechanical force to force film formation, completely overcoming the physical limitations of traditional gravity falling film evaporators. It can achieve highly efficient evaporation concentration, desolventizing, degassing, and distillation purification in a very short time, making it an indispensable core separation equipment in the fields of fine chemicals, pharmaceuticals, food, and environmental protection.
Superior performance advantages
Extremely short heating time: The residence time of materials in the evaporator is extremely short (typically only 5 to 10 seconds). Excellent anti-fouling and high viscosity adaptability: The equipment can stably handle extreme materials with viscosities up to 100,000 centipoise (CP). Extremely high heat transfer and evaporation efficiency: Its evaporation intensity can reach 150-200 kg/m²·h. Minimal system pressure drop: The system pressure drop is extremely small, thus ensuring a deeper vacuum operating environment. Flexible scraper configuration and customized design. To cater to the different physical properties of various materials, the equipment offers a variety of scraper types to choose from: Sliding scraper; Fixed scraper. Hinge scraper:
