Wiped film distillation units for laboratory use

Wiped Film Distillation Units for laboratory use

The wiped film distillation units are set-up as a module and consist in the basic configuration as follows:

  • Feeding system
  • Wiped film evaporator
  • External condenser
  • Cold trap
  • Discharge systems for distillate and residue
  • Heating system, vacuum system

The main components are fabricated in Borosilicate glass to enable observation of product properties like foaming, fouling and film distribution on the heated shell during distillation.

With wiped film distillation lab units, proper and reliable tests can be performed with 2 kg of crude material.

Following sizes are available

 

Type       
Evaporator Surface
[m²]

VDL 70-40.040.1 – 1.51
VDL 70-50.050.1 – 1.51
VDL 70-70.070.2 – 2.02

Further technical features

    • Operating pressure: 1,000 – 0.1 mbar
    • Max. melting point of the material to be processed: 150 °C
    • Max. heating temperature of jacket: 350 °C
    • Max. viscosity at operating temperature: 15,000 mPas (cP)

    Available options

    The systems are customized to the customers’ needs based on product properties and frequency of use. Besides the basic configuration the following options can be selected:

    • Continuous feeding systems
    • Continuous discharging systems for distillate and residue
    • Trace heating of individual sections (feed, residue and distillate) for melting or viscous products
    • Selection of product wetted parts in Borosilicate glass, stainless steel or other special materials and alloys
    • Combination with additional evaporation stages
    • Exchange kit to set up the system with rectification column (evaporator as reboiler)
    • PLC and visualization
