Engineer-to-order MVR (Mechanical Vapor Recompression) evaporator in food-grade stainless steel (SS316L/duplex), designed for tomato paste concentration and lactic acid process duties. The system uses electricity-driven vapor recompression to recycle latent heat, enabling low-temperature, energy-efficient evaporation with consistent product quality and predictable OPEX.

• Energy Efficiency: Electric-duty MVR minimizes fresh steam, reducing utility cost and carbon footprint.
• Quality Protection: Vacuum operation and tight ΔT control preserve tomato color/aroma and lactic acid integrity.
• Hygienic Construction: Food-contact stainless steels, drainable layouts, optional CIP/SIP for rapid turnaround.
• Process Flexibility: Recipes for tomato brix ramp-up and lactic acid concentration with controlled residence time.
• High Availability: 24/7 automatic operation, redundancy on critical skids, predictive fouling monitoring.

Secondary vapor is mechanically compressed (electric VFD) to raise saturation temperature and reused as the heating medium. Optimized ΔT/LMTD and circulation rates deliver gentle evaporation for tomato puree and thermally sensitive lactic acid streams while maximizing heat-transfer efficiency.

Wetted parts in SS316L/duplex (electropolish on request), FDA-compliant elastomers, sanitary connections, sloped/drainable piping, and validated CIP/SIP programs supporting HACCP/ISO 22000.

• Feed preparation: filtration/degassing; pH trim for lactic acid; seed/skin removal for tomato.
• MVR evaporation (vacuum): electric compressor sets ΔT for gentle concentration and target Brix/acid strength.
• Condensate management: polished for reuse (CIP water, boiler make-up) per site standards.
• Finishing: tomato: final Brix adjustment and sterilization; lactic acid: downstream polishing/neutralization as required.
• Automation: recipe-based control for product changeover and seasonal variability.

• MVR evaporator (falling film / forced circulation) with vapor–liquid separator
• Electric-driven mechanical vapor compressor (turbo/Roots) with VFD
• Preheaters, main heater, condensers, vacuum/NCG handling
• PLC/HMI/SCADA with historian; instruments (T/P/flow/cond/level/Brix)
• CIP/SIP skid; optional aroma recovery and condensate polishing filters

*Actual performance depends on feed composition, viscosity/fouling tendency, compression ratio, and HX design.
