Scraped surface evaporator for high-viscosity materials
In food processing and chemical industries, concentrating high-viscosity and high-fouling materials can be challenging. Traditional evaporation methods often fail to achieve the desired product moisture levels without compromising quality or process efficiency.
Concentrate materials to extremely high solids levels
The Convap® scraped surface evaporator by Alfa Laval is designed to handle high-viscosity and high-fouling materials with superior efficiency. The continuous scraping action and high turbulence create an impressive heat transfer coefficient, allowing it to concentrate products to nearly zero moisture. The vertical, single-wall design reduces floor space requirements, making it ideal for facilities with limited space. Operating under vacuum conditions, it preserves the color, flavor, and nutritional content of sensitive products. It is particularly well-suited for food processing applications where other methods fall short, achieving up to 99% total solids. Additionally, its robust design ensures reliable thermal performance by preventing fouling and maintaining a high temperature differential.
