Short Path Evaporators 

The unique evaporator for extraordinary applications

Short path evaporators are a specialized type of evaporator that is widely used in the pharmaceutical, chemical, and food industries for the precise distillation and separation of heat-sensitive compounds and high boiling substances. This technology is particularly noted for its ability to operate at lower temperatures and reduced pressures, which minimizes thermal degradation of the product. Here's a detailed summary of their key features and how they differ from other types of evaporators:

Short path evaporators utilize a very short distance between the heating surface and the condensing surface, which reduces the pressure drop and allows the operation under a high vacuum (often down to 0.001 mbar). The evaporator typically consists of a heated circular plate inside a chamber and a condenser located just above the heated surface. A feed mixture is introduced onto the heated plate, where it quickly forms a thin film, usually aided by a wiper system. The short path between the evaporator and condenser facilitates the immediate condensation of vapors that are formed by evaporation.
