개요

Sugar refining transforms raw cane or beet sugar into refined white sucrose through a series of dissolution, purification, and recrystallization steps. The process removes color bodies, minerals, and organic impurities to produce >99.9% pure sucrose crystals. Global production exceeds 180 million tons annually, with Brazil and India as the largest producers. The process represents one of the oldest and largest-scale purification operations in the food industry.

화학 공정

Raw sugar is dissolved in hot water to form a syrup (~65 Brix), then purified by carbonatation (adding lime and CO₂) or phosphatation to remove impurities. The clarified liquor is decolorized through activated carbon or ion exchange, concentrated by multi-effect evaporation, and crystallized in vacuum pans under controlled conditions.

Ca(OH)₂ + CO₂ → CaCO₃↓ + H₂O (carbonatation — CaCO₃ adsorbs impurities)
C₁₂H₂₂O₁₁ (dissolved, supersaturated) → C₁₂H₂₂O₁₁ (crystals) (crystallization)

원자재

  • Raw cane sugar (C₁₂H₂₂O₁₁) — Sugar mills crushing sugarcane (Crude sucrose)
  • Calcium hydroxide (Ca(OH)₂) — Lime kiln (Clarification agent)
  • Carbon dioxide (CO₂) — Lime kiln flue gas (Carbonatation agent)

최종 제품

  • Refined white sugar (sucrose) — Food ingredient and sweetener (>99.9% purity, ICUMSA 45)
  • Molasses — Animal feed, fermentation substrate, rum production (Byproduct containing residual sugars and minerals)

Environmental Impact

Sugar refining uses large quantities of water and energy for evaporation. Bagasse (sugarcane fiber) is burned as biomass fuel, making many sugar mills energy self-sufficient. Wastewater with high BOD requires treatment. Modern mills achieve near-zero discharge by recycling washwater.

안전 고려사항

최근 혁신

Membrane filtration (nanofiltration and ultrafiltration) is being adopted for syrup clarification, reducing chemical usage.
Continuous centrifugal crystallization improves energy efficiency.
