Short Path Evaporator - Design Principles

Rotor Orientation

• Vertical is used for all short path applications. The vertical configuration provides reliable, efficient processing of viscous and fouling fluids. Units are designed with no bottom bearing.

Vapor Flow

• The vapor flows radially from the liquid/concentrate stream along the thermal surface through the internal entrainment separator to the internal condenser where it is condensed to liquid. Non-condensibles exit through the vacuum nozzle. A freeze trap/coldd finger is used frequently to capture uncondensed volatiles before the vacuum system.
