The Contherm ® range of scraped surface heat exchangers can provide high efficiency and capacity in duties with challenging process requirements that can result in loss of quality or fouling in traditional heat exchangers. This includes applications involving viscous, crystallizing, sticky or heat-sensitive products, as well as those with particulate matter.
Scraped surface heat exchangers can either run full of liquid or the liquid may enter the exchanger as a peripheral stream. The former may be mounted either vertically or horizontally but it is usual for the latter, although not exclusively, to be mounted vertically so that the liquid flows downwards under the action of
Alfa Laval - Alfa Laval - Contherm scraped surface heat Contherm® scraped surface heat exchangers are a robust solution for a range of industries and applications:from food, chemicals and pharmaceuticals to health and beauty. Based on Alfa Lavals decades of expertise in thermal exchange, each unit is specially engineered to handle viscous, heat sensitive, crystallizing or sticky products, as well as those with sensitive particulate matter.
Jun 13, 2021 · Scraped surface heat exchanger is made up of a jacketed cylinder with a spinning dasher that holds rows of scraper blades. When the product is being pumped into the cylinder, the heating or cooling medium is being circulated between the cylinder and the jacket. Steam, vapor, or a refrigerant such as ammonia or freon may be used as the medium.
