The sugar manufacturing process involves 7 key steps: 1) Cutting and shredding of sugarcane, 2) Milling to extract juice from cane, 3) Clarification to remove impurities from juice, 4) Filtration to further refine juice, 5) Evaporation to concentrate juice, 6) Crystallization to form sugar crystals, and 7) Centrifugation to separate raw sugar from molasses. The process aims to produce refined sugar while extracting byproducts like bagasse, molasses, and press mud.

3. Introduction
a sweet, crystalline substance,
C12H22O11, obtained chiefly from the
juice of the sugarcane and the sugar
beet, and present in sap of
seed plants , used extensively as an
ingredient and flavoring of certain
foods and as a fermenting agent in
the manufacture of certain alcoholic
beverages.

8. Clarification
+ Liming (As Milk) in order to raise pH to 7
+ Sulphitation Colour of juice is completely bleached out
due to this process
+ Phosphatation (Flocculation)
+ Carbonation involves precipitation of calcium carbonate
through addition of lime and contacting carbon dioxide
gas.
