Introduction To Contherm scraped surface heat exchanger

Product enters the cylinder through the lower product head and flows upwards through the cylinder. At the same time, the heating cooling media travels in counter current flow through the narrow annular channel between the heat transfer wall and the insulated jacket. Rotating blades continuously remove product from the cylinder wall in order to ensure uniform transfer of heat between media and product. An optional coil in the annulus increases media velocity, adding to the heat transfer efficiency. Product exits the cylinder through the upper tangential port. On start up, air is completely purged from the Contherm. At the end of a processing run, the product can be drained or chased out by water resulting in minimal product loss. Scraper configuration, rotor diameter and rotor speed can be varied to suit the properties of the particular product flowing through the cylinder. Numerous Contherm configurations are available. Trained, knowledgeable Alfa Laval staff are able to customize each Contherm unit by selecting the appropriate materials, features and options to meet each customer s exact requirements.
