Contherm® is a single-wall scraped-surface heat exchanger (SSHE) designed for continuous and semi-continuous processing of an extremely broad range of viscosities. Its unique design offers impressive flexibility in heating and cooling operations for numerous products, with or without particles.
Contherm® represents the most versatile heat transfer solution on the market, suitable for a wide range of applications and industries. The unique design provides low hold-up volumes and can handle product pressures up to 21 bar (300 PSI), with rotational scraping speeds ranging from 25 to more than 1000 rpm. This flexibility creates countless opportunities for the production of food products, protein by-products, chemicals, pharmaceuticals, personal care products, and much, much more.
- Versatile solution that can handle particles up to 36 mm and viscosities well in excess of 50,000 cP.
- Easy-to-clean design can flexibly transition between products with limited downtime.
- Multiple material options ensure efficient heat transfer and reliable mechanical performance.
- Flexible installation with horizontal or vertical configuration to meet space limitations.
- Vertical installations include a built-in hydraulic system that allows for fast and safe inspection with low service costs.
The scraped-surface heat exchanger principle
In scraped-surface heat exchanger applications, the product enters the cylinder at the bottom and flows upwards. The heating or cooling medium travels in a counter-current flow through a narrow annular channel.
Rotating blades continuously remove product from the cylinder wall to ensure uniform heat transfer. The product enters the cylinder in a corkscrew pattern in the same direction as the rotating scraping assembly. This preserves product quality by reducing shear, providing gentler product handling and reduced pressure drop across the inlet. Finally, the product exits the cylinder at the top.
Both product flow and rotor speed can be adjusted to suit the particular properties of the product in the cylinder.
