Products Description
Wiped-Film Still equipment, also known as Molecular Stills, Short-Path Stills, Short-Path Evaporators, Thin Film Stills, Wiped-Film Evaporators, or Thin Film Evaporators, is engineered to excel in challenging thermal separation applications involving heat-sensitive materials.
This equipment operates by feeding a fixed rate of starting liquid material into the interior of a vertically heated cylindrical chamber. Inside the chamber, the material is continuously wiped into a turbulent, thin film across the heated surface under high vacuum conditions, facilitating the efficient evaporation of more volatile components.
The design ensures minimal residence time (mere seconds) at vacuum-reduced temperatures, yielding two product streams: distillate and residue, both collected under cooled conditions. Landerlee's Molecular Stills incorporate all these features, enabling successful distillation processes that minimize degradation while maximizing product quality, yield, and value.
Designed specifically for distilling high-boiling-point materials, our Molecular Stills achieve the strongest vacuum levels and feature a minimal distance between the evaporator and internal condensers. This proximity reduces thermal degradation of sensitive compounds. Typical applications include processing triglycerides, diglycerides, long-chain free fatty acids, tall oils, polymers, and cannabinoids.
