Sugar Production Process in Iran

Sugar Production Process in Iran

1. Receiving and Preparing Raw Material
   • Sugar Beet:
     Beets are transported from the fields to the factory.
     Initial cleaning involves separating dirt, stones, and impurities through washing and screening.
   • Sugarcane:
     Sugarcane stalks are transported to the factory after harvesting.
     Leaves and impurities are removed from the stalks.
2. Extraction of Raw Juice
   • Sugar Beet:
     Beets are sliced into thin sheets.
     They enter a diffusion machine where hot water extracts the sugary juice.
   • Sugarcane:
     The sugarcane stalks are crushed and then milled.
     The raw juice (sugarcane juice) is extracted under pressure from the stalks.
3. Refining of Raw Juice
   • Adding Chemicals:
     Lime is added to the juice to separate impurities.
   • Heating the Juice:
     The juice is heated, and impurities settle as sediments.
   • Settling and Filtering:
     The juice is clarified.
4. Concentration of Juice (Evaporation)
   • The sugary juice enters evaporators.
   • Under heat and vacuum conditions, the water evaporates, and a thick syrup is obtained.
5. Crystallization (Sugar Crystallization)
   • The concentrated syrup is transferred to crystallizers.
   • Sugar crystals form as the syrup cools gradually.
6. Centrifugation (Separation of Crystals)
   • The mixture of sugar crystals and molasses enters a centrifuge.
   • The centrifuge separates the molasses through rapid spinning, leaving behind white sugar.
7. Drying the Sugar
   • The wet sugar enters dryers.
   • Warm air is used to remove moisture from the sugar.

8. Packaging the Sugar

   • The dried sugar is packaged in bags or smaller containers for domestic or industrial use.
