Pilot plants with wiped film evaporator / thin film evaporator

Pilot Plants with wiped film evaporator / thin film evaporator

The pilot wiped film distillation systems are set up as modules and consist in the basic configuration as follows:

    • Feeding system
    • Feed pre-heating
    • Degassing stage
    • Wiped film evaporator / Thin film evaporator
    • External condenser
    • Cold trap
    • Discharge systems for distillate and residue
    • Heating and cooling systems
    • Vacuum system

    With pilot wiped film distillation units already with 30 kg of crude material, proper and reliable tests can be performed.

    Following sizes are available

    Type            Evaporator Surface
    [m²]
    Feed Rate Required
    [kg/h]
    Required Crude Amount
    [kg]
    VD 83-60.065 - 1230
    VD 125-200.2015 - 40100
    VD 200-500.5040 - 100300

    Further technical features

      • Operating pressure: 1,000 – 0.1 mbar
      • Max. melting point of the material to be processed: 190 °C
      • Max. heating temperature of jacket: 400 °C
      • Max. viscosity at operating temperature: 100,000 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:

      • Trace heating of individual sections (feed, residue and distillate) for melting or viscous products
      • Selection of product wetted parts in stainless steel or special materials and alloys
      • Combination with additional evaporation stages
      • Continuously operating unheated and heated transfer stages
      • Exchange kit to set up the system with rectification column (evaporator as reboiler)
      • PLC and visualization
