Thin Film & Wiped Film Evaporation & Distillation

Thin Film & Wiped Film Evaporation & Distillation is a high-performance device for separating liquid mixtures. During operation, the liquid mixture to be processed enters the device and is evenly distributed across the heated surface to form a thin film. Wiped film devices, using a specific scraper system, force the liquid to form a thinner, more uniform, and turbulent film on the heated surface, significantly improving mass and heat transfer efficiency. In this thin film state, low-boiling point substances quickly evaporate from the film surface. The vapor is then condensed and collected in a condenser, while the high-boiling point residue is discharged from the bottom of the device, achieving efficient separation of the mixture.

• Efficient Heat and Mass Transfer: The formation of a thin film significantly increases the contact area between the liquid and the heating surface, and between the steam and the condensing surface. The wiper blades of the Wiped Film Molecular Distillation system create a turbulent thin film, further enhancing the heat and mass transfer process. This significantly improves evaporation and distillation efficiency, enabling rapid separation of mixtures. This can significantly shorten production cycles, for example, in the extraction of chemical raw materials.
• Low Thermal Stress: Because the liquid exists in thin film form and its residence time within the system is extremely short, the thermal stress experienced by the Thin Film Evaporator Molecular Distillation System is minimized, preserving the product's original properties and quality to the greatest extent possible.
• Adaptable to a Wide Viscosity Range: This system is well suited for liquids ranging from low viscosity to materials with viscosities of tens of thousands or even hundreds of thousands of centipoise.
• Flexible Operating Pressure: The operating pressure can be flexibly adjusted according to demand. By reducing the pressure, the boiling point of the product can be effectively lowered, enabling evaporation and distillation at lower temperatures. This is particularly important for separating materials with high boiling points and strong heat sensitivity, while also reducing energy consumption. Compact structure: The overall structure is relatively simple and compact, with a small footprint, making it easy to install and maintain. Internal components such as scrapers and heating surfaces are rationally designed and easy to disassemble and clean, reducing maintenance workload and costs while improving operational stability and reliability.
