CASE STUDY
Sustainable aroma preservation with Sulzer EvapCare™-F
The project focused on preserving the product’s delicate aromas, as its natural molecules were highly sensitive and required processing below 50 °C. Any deviation risked altering flavor and quality. At the same time, the client sought to reduce waste and maximize recovery, goals traditional systems could not meet due to high liquid waste. EvapCare™-F was designed to deliver both efficiency and sustainability.

EvapCare film evaporators portfolio
Featuring a vertical condenser placed inside the wiped evaporation chamber, the Short Path evaporator shows a very low pressure drop across the system
EvapCare-F masters the Marangoni effect, which uses surface tension gradients to create a uniform liquid film across heated tubes preventing dry zones and thermal degradation. The combination of short residence time, vacuum operation, and low pressure drop ensures gentle evaporation that preserves organoleptic properties like color, smell, and taste. This makes it highly suited for industries such as pharmaceuticals, fine chemicals, and food processing.
EvapCare-F delivers high heat transfer coefficients, enabling rapid evaporation with minimal energy use. It offers high evaporation ratios, is low-susceptible to fouling, operates under deep vacuum, and supports both single-stage and multi-stage systems even in co-current or counter-current setups. These features enhance purity, yield, and operational uptime.
This falling film evaporator excels in applications involving low-viscosity, low-fouling products, commonly found in the chemical, petrochemical, and polymer industries. It is also used as a column reboiler in distilCare vacuum distillation systems by Sulzer, and supports typical operations like product purification, solvent recovery, concentration of slurries, degassing, and stripping of waste streams.
Sulzer brings over 60 years of experience and thousands of global installations to the table. Each client’s feed is tested in Sulzer’s pilot plant facilities, or via mobile test units, to ensure correct sizing and process performance. This guarantee allows seamless scale-up and ensures the EvapCare™-F unit meets your exact product and purity requirements.
The evaporator features a proprietary two-stage liquid distribution system that ensures even feed coverage across all tubes—even across large diameters and lengths. Options include both co-current and counter-current configurations, customizable size ranging from 0.3 to 4800 m², and GMP-compliant designs. This combination of versatility and precision ensures optimal performance no matter the scale or complexity.
