Multi-Effect Evaporation

Product Structure

Comprises preheaters, evaporators, separators, condensers, vacuum systems, and control systems. The evaporators are connected in multiple stages (effects), each equipped with a heating chamber and separation chamber. Piping and valves enable efficient circulation of materials and steam across stages.

Operating Principle

Preheated material enters the first effect evaporator, where partial evaporation occurs using primary steam. Subsequent effects utilize secondary vapor from the previous effect as heat sources, progressively lowering operating pressures to enable low-temperature evaporation. This cascading energy reuse minimizes thermal degradation of heat-sensitive components. Final concentrate discharges from the last effect, with condensed vapor recovered to significantly reduce energy consumption.
