Short Path Distillation
Short-Path Distillation is a thermal separation process for thermal sensitive products.Typical applications are high molecular organic compounds particularly from the fields of chemistry, pharmaceutical and food industry. Distillation is
one of the most important thermal separation methods. Short-Path Distillation is a continuous separation process working under vacuum conditions. Evaporation takes place from a heated wiped film. Caused by the pressure drop between the place of vaporization and the vacuum system the operating pressure in typical wiped film evaporators with external condenser is limited to some millibars. The considerably lower pressure in the Short Path Evaporator is obtained by the short distance for the vapors on their way from the evaporator surface to the condenser. In addition, the cross section area of flow is equal to the evaporator surface, so that there is only a minor pressure drop between evaporator and condenser - a detail which is absolutely necessary for this process!
