Scraped surface heat exchanger for viscous products
Efficiently handle challenging viscosities and heat-sensitive products with continuous and semi-continuous processing while maintaining product quality through advanced heat transfer and gentle product handling.
Processes Viscous and Heat-sensitive Products Efficiently
The Contherm Scraped Surface Heat Exchangers from Alfa Laval are engineered for continuous and semi-continuous processing of highly viscous and heat-sensitive products across diverse industries, including food, pharmaceuticals, and chemicals. With a design that facilitates optimal heat transfer and gentle product handling, the Contherm range excels in applications requiring precise temperature control and minimal fouling. This single-wall heat exchanger operates via rotating blades that scrape and remove product from the cylinder wall, ensuring uniform heat exchange in both heating and cooling modes.
It is suitable for handling viscosities beyond 50,000 cP and pressures up to 21 bar, making it ideal for products such as sauces, creams, emulsions, and more. The equipment offers variable scraping speeds from 25 to over 1000 rpm and product flows designed to minimize pressure drops, preserving product integrity. Installation flexibility permits both horizontal and vertical configurations, with vertical units featuring a hydraulic system for easy inspection, reducing service costs.
Material options accommodate efficient heat transfer and resist corrosion, catering to different production environments. The system supports integration with PLCs for automated control, reducing energy consumption by optimizing motor speeds. Cleaning is streamlined through a design that accommodates rapid product switchover with limited downtime, enhancing operational efficiency. The Contherm family is customizable to meet specific production needs, supported by Alfa Laval’s comprehensive engineering and service solutions to ensure continuous top performance and profitability.
