Hybrid MVR falling film evaporator integrated with a multiple-effect (MEE) train for raw, refined, and back-end molasses clarification lines. The system concentrates juice/syrup at low temperature under vacuum, recycling latent heat via mechanical vapor recompression for low OPEX, improved color control, and stable throughput during long campaigns.

• Energy economy: MVR duty plus staged effects cuts steam consumption and boiler load.
• Product quality: Low ΔT falling film preserves sucrose, reduces inversion and color formation.
• High capacity: Even film distribution and optimized residence time deliver steady °Brix rise.
• Cleanability: CIP-ready geometry with scale control for long, predictable campaigns.
• Flexible retrofit: Add MVR to existing effects or deploy as a greenfield hybrid line.

Juice/syrup enters preheaters, then flows as a thin film down vertical tubes at vacuum. Vapor from later effects is mechanically recompressed and reused as the primary heating medium. Balanced Δ T/LMTD and circulation maintain high coefficients with minimized sucrose degradation.

Wetted parts in SS316L (duplex/Ti on request). Food-grade finishes, drainable layouts, and validated CIP support HACCP/ISO programs in sugar processing.

• Feed prep: clarification/filtration, pH trim, antiscalant (Ca/Mg/Si control) as required.
• Multiple effects (vacuum): staged shell pressures reduce boiling point progressively.
• MVR module: compressor raises vapor temperature; provides primary duty to lead effect(s).
• Condensate management: polishing for reuse; conductivity/TOC guard optional.
• To pan/crystallization: target °Brix delivered with stable color and viscosity.

• Falling-film calandrias per effect with distributors and vapor-liquid separators
• MVR compressor (turbo/Roots) with VFD for ΔT/capacity control
• Preheaters, surface condenser, vacuum/NCG handling skid
• PLC/HMI/SCADA; instruments (T/P/flow/cond/level/°Brix)
• CIP skid; antiscalant dosing and fouling monitors

Can MVR be retrofitted to our existing effects?
Yes. A lead-effect MVR module or hybrid tie-in can reduce steam demand without replacing the whole train.

How is sucrose inversion minimized?
Operate at low ΔT and vacuum, limit residence time, and maintain pH control; CIP restores peak heat transfer.

What about scale on tubes?
Softening/antiscalant, optimized velocity/ΔT, and scheduled CIP windows maintain coefficients across the campaign.
