This document provides an overview of the sugar manufacturing process. It discusses the key steps which include harvesting sugarcane, transportation, washing, cutting, shredding, crushing, milling, clarification, filtration, evaporation, crystallization, centrifugation, drying, packaging, and production of raw and refined sugar. The Rajasthan State Ganganagar Sugar Mills located in Sriganganagar, Rajasthan is used as an example throughout to explain the various stages involved in sugar production.

- 12. Material Handling and Storage • Stored in cane yards • Carried from cane yard to feeding area by • hook/chain • Cranes • Reelings • Conveyer belt • Carry • Huge suction truck
- 14. Washing
- 15. Cutting of Canes • To aid the cane crushing • Cane knives to cut cane into small pieces
- 16. FLOW DIAGRAM
- 17. Shredding • To remove leaves and nodes • Hammer mill shredder
- 19. CRUSHING • Cane crushed to break hard structure • No juice extracted • Increase efficiency of juice extraction • Subjected to crusher with corrugated blades
- 20. FLOW DIAGRAM
- 21. MILLING TANDEMS • 3 roller mills connected in series • Top roller • Feed roller • Discharge roller • 5-7 in number • Extract the juice from crushed cane
- 24. FLOW DIAGRAM

- 42. RAW & REFINED SUGAR • Raw sugar • Obtained directly from sugarcane juice without refining • Most natural sugar • Brown in color due to molasses • Refined sugar • Have white luster and transparent • Bleached to remove color and other impurities
Notas del editor
- FlocculantPolyelectrolyte in solution added to juice to assist clarification. The increase in alkalinity coagulates proteins in the juice. Calcium carbonate absorbs colourants Alkalinity destroys some monosaccharide sugars, mostly glucose and fructose
- Phosphatation involves addition of lime (CaO) and phosphoric acid (H3 PO4 or P2 O5 ) to the melt liquor which results in formation of a calcium phosphate precipitate. Color bodies adsorb onto the calcium phosphate precipitate and are removed during the subsequent clarification and filtration. Polymers are added to aid in the formation of a precipitate floc which is more easily filtered.
- Filter cakeMaterial retained on the filter screens and discharged from the filters after filtering clarifier muds.FiltrateLiquid passed through the screens of the filters.
- CalandriaTubular or plate heating element in a vacuum pan or evaporator vessel.
- 3 zones of supresat Metastable, intermediate, labile zones… molecules arrange in crystallization pattern and form a site of attachment of crystals
- Seed Suspension of fine crystals in saturated solution of alcohol
