A Short Path Distillation Unit (SPDU), A different from a standard Agitated Thin Film Evaporator by incorporating an internal condenser. The system minimizes pressure drop by providing vapours generated on the heated surface with a short path to the condenser. With this design, it is possible to operate at vacuum levels as low as 0.001 mbar.

Features

  • Operation pressure as low as 0.001 mbar(a). Hence production can be distilled at lower temperatures to avoid degradation.
  • Suitable for processing heat-sensitive, high-boiling point materials with minimal thermal stress.
  • Achieves the desired distillation in a single pass
  • a short retention time of only a few seconds
  • Offers excellent turn-down capabilities
  • Along with degasser
  • Use of metal blades at high temperature gives more flexibility than conventional roller design.

Applications

  • Purification of natural and synthetic waxes
  • Re-refining of used lubricating oils
  • High vacuum distillation of fatty acids, fish oil, omega-3 fatty acids, glycerides and cardanol.
  • Distillation of pharmaceuticals, bulk drugs, esters, and tocopherols
  • Processing of epoxy resins, plasticizers, and stabilizers
  • Separation of fine chemicals, silicone oils, and higher alcohols
