Horizontal Thin Film Evaporators

Process solution for special requirements

The working principle of horizontal thin film evaporators is similar to vertical thin film evaporators.
However the horizontal design allows highest flexibility in terms of residence time, evaporation rates and turn-down ratios.
The recovery of large solvent amounts from viscous products, processing of inhomogeneous products or performing
continuous reactions are applications for this technology.
For pharmaceutical or food applications horizontal thin film evaporation plants can be designed for full GMP and in hygienic design.

Performance features

  • Capacity: 0,1 kg/h up to several t/h
  • Operating pressure:
    full vacuum to overpressure
  • Evaporation ratio: max. 99.5%
  • Turn down ratio: not limited
  • Visosity: max. 75.000 mPas
    at operating temperature
  • Residence time: adjustable
  • Continous reactions: possible

Typical Applications

Processing of thermal sensitive, viscous or foaming products such as

  • Lecithin drying
  • Concentration of natural extracts
  • Peptide solutions
  • Solvent recovery from polymer side streams
  • Active pharmaceutical ingredients
  • Acrylic polymers

    VTA − plant design at its best

    VTA delivers package units in laboratory, pilot and industrial scale. Package units are skid mounted, pre-assembled systems for wiped film
    and short path distillation, rectification and thin film drying.
    All core components, like evaporators, condensers, vessels and piping, are manufactured in modern manufacturing facilities by highly qualified
    workers either by VTA or within the STREICHER group.
    All engineering services are performed entirely inhouse at VTA. By minimizing the interfaces, a smooth project execution is ensured.
