ISO Multiple Effect Evaporation System for Juice Concentration
Hanpu’s ISO-compliant Multi-Effect Evaporator (MEE) is engineered for fruit and vegetable juice concentration with gentle heat treatment, high aroma retention, and best-in-class steam economy. Hygienic design, full CIP/SIP capability, and precise °Brix control ensure consistent quality for export-grade concentrates.
Gentle, Low-Temperature Concentration
Vacuum operation lowers boiling points to protect color, vitamins, and volatiles.
High Steam Economy
Cascaded effects reuse latent heat; optional TVR/MVR further reduces utility costs.
Hygienic Construction
SS316L product contact, sanitary mirror tubes, crevice-free layout, automatic CIP/SIP.
Accurate °Brix & Aroma Control
Inline refractometer/density control and optional aroma recovery assure premium flavor profiles.
Process Overview — Falling-Film Multi-Effect under Vacuum
- Feed & Preheat: Clarified juice is preheated via condensate to reduce steam usage.
- Effect 1 → Effect 2 → Effect 3: Live steam heats the 1st effect; its vapor heats the next, with progressively lower pressure and temperature.
- Brix Control: Inline refractometer governs discharge vs. recycle to hit target °Brix.
- Aroma Recovery (optional): Stripped volatiles condensed and dosed back into concentrate.
- Utilities: Final vapor condenses in surface condenser; clean condensate recovered; non-condensables removed by vacuum pump.
