Scraped surface evaporator for high-viscosity materials
Efficiently concentrate high-viscosity and hard-to-handle materials with advanced evaporator technology, ensuring reliable heat transfer and preserving product quality, even under challenging production conditions.
Concentrates and Dries High-Viscosity Materials
The Convap® Scraped Surface Evaporator from Alfa Laval uniquely addresses the challenges of processing high-viscosity and high-fouling materials. Utilizing continuous scraping and mechanical agitation, it achieves superior heat transfer efficiency, reducing moisture content to near zero. Commonly employed in the food, cosmetic, and dairy industries, it effectively concentrates products like fruit preparations, sauces, and dairy desserts. Operating under vacuum conditions, it preserves the quality of heat-sensitive components while integrating seamlessly into continuous processing lines. The vertical design ensures a minimal footprint, and options for stainless steel construction provide excellent corrosion resistance. Engineered for reliability, it features a robust build that minimizes fouling, thus maintaining optimal thermal performance and reducing maintenance needs. Compliance with industry standards makes it suitable for a wide range of applications.
