Thin film evaporator for temperature sensitive products
Need to purify temperature-sensitive compounds efficiently? Achieve high evaporation rates with minimal thermal degradation by utilizing thin film evaporation technology for precise control over residence time and temperature.

Purifies and Concentrates Temperature-Sensitive Liquids
The Glass-Lined Thin Film Evaporator from De Dietrich Process Systems offers an efficient solution for the purification and concentration of temperature-sensitive substances across various industries. This equipment employs a rotating wiper system to form a thin liquid film on the evaporator’s inner wall, minimizing residence time and thermal degradation. Ideal for applications in specialty chemicals and pharmaceuticals, it effectively handles processes like methyl ester and glycerine evaporation, solvent stripping, and drying.
Capable of processing diverse materials such as acrylic polymers and active pharmaceutical ingredients, the evaporator supports pilot to continuous operations with excellent energy efficiency. Its construction from corrosion-resistant borosilicate glass and glass-lined steel ensures durability, while the transparent design facilitates direct process observation. The wiper system includes options with PTFE elements for lower-temperature processes or metallic wipers for higher-temperature requirements, accommodating a wide temperature range up to 200°C.
Fully compliant with vacuum and hygiene standards, this solution integrates seamlessly into existing lines, optimizing solvent and energy use and reducing operational costs. Easy integration with automated systems and quick clean-in-place (CIP) features ensures smooth maintenance and operational efficiency. De Dietrich also offers customizable configurations to meet specific production needs and provide comprehensive engineering support.
