Sugar Processing Overview

Sugar Processing Overview

• Sugar processing involves the extraction of sugar from sugarcane or sugar beets, followed by purification and crystallization to produce refined sugar.

Steps in Sugar Processing

1. Harvesting: Sugarcane or sugar beets are harvested and transported to the processing plant.
2. Extraction: Juice is extracted from sugarcane or sugar beets using a machine called a juicer or through diffusion.
3. Clarification: The extracted juice is treated with lime to remove impurities and clarify the juice.
4. Evaporation: The clarified juice is heated to remove excess water and concentrate the sugar content.
5. Crystallization: The concentrated juice is then seeded with sugar crystals, allowing sugar crystals to form.
6. Centrifugation: The resulting mixture of sugar crystals and mother liquor is separated using centrifuges.
7. Drying: The sugar crystals are dried to remove any remaining moisture.

Types of Sugar Produced

• Raw sugar: Produced after crystallization, it contains impurities and moisture.
• Refined sugar: Produced after further processing and purification of raw sugar.

By-Products of Sugar Processing

• Molasses: A thick, dark liquid produced during the crystallization process, used as animal feed or in the production of ethanol.
• Bagasse: The fibrous residue remaining after juice extraction from sugarcane, used as fuel or in paper production.

Energy Production in Sugar Processing

• Cogeneration: Many sugar processing plants generate electricity and heat using bagasse and other biomass sources.
• Bioethanol production: Some sugar processing plants produce bioethanol from sugarcane juice or molasses.
