5T/H Stainless Steel MVR Evaporator Oslo Crystallizer Used In NaCl Indutries
A stainless-steel MVR (Mechanical Vapor Recompression) evaporator integrated with an OSLO (draft-tube baffle) crystallizer, engineered for NaCl brine concentration and crystal growth at a nominal 5 t/h water removal. Recompressing secondary vapor as the heating medium delivers low OPEX, stable supersaturation, and consistent salt quality for edible and industrial grades.
Key Benefits
Energy saving: Electric-driven MVR minimizes fresh steam after start-up.
Crystal quality: OSLO circulation promotes larger, well-formed NaCl crystals with narrow PSD.
Food/industrial compliance: SS316L wetted parts with hygienic finishes; duplex/Ti optional for chlorides.
Continuous uptime: PLC/HMI recipes, alarms, historian, and remote diagnostics for 24/7 operation.
Process & Thermal Economy
Purified brine is evaporated under vacuum; the MVR compressor raises vapor temperature and recycles latent heat. The OSLO crystallizer operates at controlled slurry density and residence time to stabilize supersaturation and crystal growth while keeping specific energy consumption low.
Materials & Sanitary Design
Wetted parts in SS316L (duplex/SS2205 or titanium available). Drainable layouts, smooth finishes, and validated CIP support edible salt production and robust industrial service.
5 t/h (water removal), adjustable via compressor VFD

*Performance depends on brine composition, scaling tendency, compression ratio, and crystallizer design.
FAQ
Why choose an OSLO crystallizer for NaCl?
OSLO’s draft-tube circulation supports growth of larger, uniform crystals with low fines, improving centrifuging and drying.
Can this line produce edible-grade salt?
Yes—with proper brine purification, hygienic finishes, and iodization/anti-caking dosing, edible-grade specs are achievable.
How is scaling controlled?
Softening and filtration upstream, optimized ΔT/velocity, antiscalant dosing, and scheduled CIP maintain heat-transfer rates.
