Scraped Surface Heat Exchanger (SSHE)

The Contherm Scraped Surface Heat Exchanger (SSHE) is particularly suited for processing viscous, sticky, or chunky (containing particles) products that are to be pumped. The product is pumped into the lower end of the heat exchange cylinder. As it flows through the cylinder, it is continuously agitated and removed from the cylinder's precisely finished walls by the scraping blades.

The scraping action results in thin film product heating or cooling, a surface free from fouling deposits and a corresponding high heat transfer rate. Heating or cooling media flows in the annular space between the heat exchange cylinder and the insulated jacket. When liquid media or steam is used, a spiral coil is installed in the annulus to provide a higher heat transfer efficiency.
