Food- and chemical-grade SS316L NaCl evaporation & crystallization line engineered for refined sodium chloride. The system integrates brine purification with vacuum evaporation (MEE and/or MVR) and controlled crystallization to deliver consistent grain size, high purity, and low moisture--ready for centrifuging, drying, sizing, iodization, and packing.
Clarified/polished brine is concentrated under vacuum using multi-effect and/or MVR duty. Tight control of Δ T/LMTD, circulation rate, and residence time stabilizes supersaturation, ensuring repeatable crystallization and low energy consumption.
Wetted parts in SS316L (duplex/Ti on request). Sanitary finishes, traceable materials, drainable piping, and validated CIP supporting HACCP/ISO programs for edible salt production.
Parameter | Typical Target / Range* |
---|---|
NaCl purity (dry) | ≥ 99.2% (up to 99.7% with enhanced purification) |
Final moisture | ≤ 0.2% (grade-dependent) |
Crystal sizes | Fine 0.2-0.5 mm; Table 0.5-1.2 mm; Coarse 1.2-2.5 mm |
Line capacity | 5-500 t/day (modular trains) |
Energy use (MVR) | ~15-40 kWh per ton H₂O evaporated |
Fresh steam demand | Very low after start-up (with MVR) |
Campaign length | ≥ 10-20 days between CIP (feed-dependent) |
Can the system produce multiple grain sizes?
Yes. We tune nucleation/growth and add post-sieving/polishing to supply fine, table, or coarse grades.
Is food-grade documentation available?
Material traceability, surface-finish records, and CIP validation are provided to support HACCP/ISO 22000.
How is energy consumption minimized?
Through multi-effect staging and optional MVR, plus heat recovery and optimized ΔT/LMTD and circulation.
