EvapCare™ Film Evaporation Technology: The Gold Standard for Product Purification

Introduction

Achieving high product purity is a critical challenge for industries such as chemicals, pharmaceuticals, and food processing. Traditional separation methods often struggle with heat-sensitive or complex mixtures, risking product degradation or loss of valuable components. Sulzer’s EvapCare film evaporation technology offers a gentle, efficient, and reliable solution for product purification and solvent recovery setting a new standard for process excellence.

Overview of Film Evaporation Technology

Sulzer’s film evaporators are designed to handle a wide range of applications, including product purification, solvent recovery, concentration of solutions and slurries, degassing, and stripping to reduce industrial waste streams. These evaporators are used both as standalone equipment and as key components in vacuum and high-vacuum rectification and distillation systems.

Types of Evaporators

• Falling Film Evaporator (EvapCare™-F):

  Ideal for heat-sensitive, low-viscosity products with minimal fouling tendency. The proprietary liquid distribution system ensures an even, continuous film for gentle and efficient evaporation.

• Wiped Film Evaporator (EvapCare™-W):

  Designed for continuous processing of heat-sensitive, viscous, or fouling products. A mechanical rotor distributes and mixes the liquid film, minimizing fouling and ensuring high heat transfer.

• Short Path Evaporator (EvapCare™-S):

  Specifically suited for extremely heat-sensitive compounds and high molecular weight substances. The very short distance between heating and condensing surfaces allows evaporation at ultra-low pressures, preserving product quality.

  
  

Key Benefits

• Gentle Product Handling:

  Short residence time and low temperature differences protect sensitive products from degradation.

• High Purity and Yield:

  Efficient removal of solvents and impurities, even down to ppm levels, while maximizing product recovery.

• Wide Application Range:

  Suitable for chemical, pharmaceutical, food and beverage, biotech, oleochemical, and nutraceutical industries.

• Cost-Effective and Reliable:

  High heat transfer coefficients, low energy consumption, and robust design ensure efficient, long-term operation.

• Customizable Solutions:

  Standard and tailor-made sizes available, with options for GMP compliance and special requirements like glass-lined units.

  
  

How EvapCare Supports Your Process

EvapCare evaporators enable you to produce high-purity substances from heat-sensitive and complex products. The use of vacuum and the short contact time with heated surfaces prevent quality deterioration through secondary reactions, such as polymerization and condensation. This is crucial for preserving color, smell, and taste—essential in industries like food, fine chemicals, and pharmaceuticals.

Sulzer provides both static and mechanically agitated film evaporators, supporting continuous improvement of product purity and yield. The proprietary distribution system ensures uniform film formation, eliminating dry zones and preserving product quality.

Industries & Applications

EvapCare film evaporators are widely used for:

• Chemical and Fine Chemical Industry: Purification of intermediates and final products.

• Pharmaceutical Industry: Recovery and purification of active pharmaceutical ingredients (APIs).

• Food and Beverage Industry: Concentration and purification of flavors, fragrances, and food additives.

• Biotech and Nutraceutical Industry: Processing of sensitive biological compounds and supplements.

• Oleochemical Industry: Purification and concentration of edible oils and derivatives.

  
  

Conclusion

Sulzer’s film evaporation technology is the gold standard for product purification and solvent recovery in demanding industrial environments. By combining gentle processing, high efficiency, and reliable scale-up, these solutions help you achieve superior product quality and operational performance.
