▎Equipment Applications

Scraped film evaporators utilize scraped film formation technology to create a rapidly flowing thin film of material on the inner wall of the evaporator. This ensures both heat transfer area and efficiency. Furthermore, the high vacuum within the system allows for large-scale evaporation of materials at relatively low temperatures in a short time, making it ideal for processing heat-sensitive and high-viscosity materials. It is an ideal choice for pilot-scale and industrial production equipment.

▎Working Principle

Scraped film evaporators mainly consist of a heating jacket, internal rotatable scrapers, a condenser, and a vacuum system. In a high-vacuum environment, the feed liquid is added tangentially from the top of the evaporator. Under the influence of gravity and the rotating scrapers, it forms a downward-swirling thin film along the inner wall of the shell. The finished liquid is discharged from the bottom, while the secondary steam is discharged from the top.
