Surface Scraped Heat Exchanger-SPX

Short Description:

SPX series Scraped surface heat exchanger is particularly suited for continuous heating and cooling of viscous, sticky, heat-sensitive and particulate food products. It can operate with a wide range of media products. It is used in continuous processes such as heating, aseptic cooling, cryogenic cooling, crystallization, disinfection, pasteurization and gelation.

Working Principle

The product is pumped into the lower end of the heat exchanger cylinder. As the product flows through the cylinder, it is continuously agitated and removed from the cylinder wall by the scraping blades. The scraping action results in a surface free from fouling deposits and a uniform, high heat transfer rate.
The media flows in counter current direction in the annular space between the heat transfer cylinder and the insulated jacket. A spiral coil provides a higher heat transfer efficiency for steam and liquid media.
Rotor driving is achieved by an electric motor installed on the upper shaft end. Rotor speed and product flow can be varied to suit the application.
SPX series scraped-surface heat exchangers can be connected in series for in line heating and cooling.

Standard Design

SPX series Scraped-surface heat exchanger utilities a modular design for vertical mounting on a wall or column and includes:

Material

The heating surface is normally made of stainless steel, (SUS 316L), honed to a very high finish on the inner surface. For special applications different types   of chrome coatings are available for the heating surface. The scraping blades are available in stainless steel and different types of plastic materials including a metal detectable type. The blade material and configuration is selected based on the application. Gaskets and O-rings are made of Viton, nitrile or Teflon. Suitable material will be selected for each application. Single seals, flushed (aseptic) seals are available, with material selection depending on the application
