Fine chemicals
Concentration and solvent removal from specialty chemicals and process intermediates.
Thin Film Evaporators
A rotating wiper distributes the liquid over the heated surface as a thin film. Short residence time and vacuum operation help reduce thermal exposure while concentrating or separating process streams.
01 / Configuration criteria
Technology guided by the application.
Short-residence-time concentration for heat-sensitive and viscous products.
These are configuration criteria, not guaranteed values for every system.
Film formationMechanical wiper distributes a thin film
Residence timeDesigned for short contact with the heated wall
Operating pressureVacuum capability defined by process duty
Condenser arrangementExternal condenser for the evaporated fraction
Design basisThermal sensitivity, viscosity and separation objective
02 / Application areas
Where these systems are applied
Pharmaceutical intermediates
Short-residence processing where sustained thermal exposure is undesirable.
Food, aromas & natural products
Separation and concentration of selected aroma and botanical fractions.
Heat-sensitive oils & lipids
Low-residence processing of sensitive oil and lipid streams.
Polymers & specialty materials
Management of viscous streams, additives and specialty intermediates.
03 / System technology
How wiped thin-film evaporation works
A rotating wiper spreads feed into a thin film on the heated evaporator wall. Volatile compounds leave as vapor for an external condenser; less volatile material exits as residue.
