Falling Film Evaporator (FFE)
Highly effective for concentrating heat-sensitive solutions with very short product contact times — usually a few seconds per pass — and minimal temperature difference between heating medium and boiling liquid.
A Falling Film Evaporator is a highly effective industrial device for concentrating solutions, especially those containing heat-sensitive components. It operates on the principle of a thin film of liquid falling under gravity that is partially vaporized by the heat source. Product contact time is very short — usually a few seconds per pass — and the system functions with very small temperature differences between the heating media and the boiling liquid. These qualities make it the most widely used evaporator type for heat-sensitive applications. Semco plants are also capable of drying whole egg, egg yolk, and egg white (albumen) using integrated spray drying.

Typical Applications
Other Equipment in This Category
Agitated Thin Film Evaporators (ATFE)
Ideal for heat-sensitive, high-viscosity, and fouling materials — converts liquids, slurries, and pastes to free-flowing solids in continuous, single-pass operation with self-cleaning heating surfaces.
Forced Circulation Evaporator
Leading forced circulation evaporator for viscous, scaling, or crystallizing solutions — uses continuous pumped circulation to maximize heat transfer and separation efficiency.
MVR Evaporator
Mechanical Vapor Recompression technology requiring up to 90% less external steam — dramatically cuts operating costs and carbon footprint for concentration-intensive processes.
Multi-Effect Evaporator (MEE)
At SEMCO, we design and manufacture high-performance Multi-Effect Evaporators (MEE) tailored for efficient solution concentration and robust industrial effluent treatment.
