1. .Description of the process
The juice is extracted by passing the crushed cane, through a series of four mills, each
of which consists of three grooved rolls that exert high pressure. Water and weak juices
may be added to macerate (to make soft by soaking) the cane and in the extraction of
juice. About 93% of juice is extracted.
2.
3. Mud produced by settlement in the clarifier is filtered through a vacuum filter. Vacuum
filtration of mud results in juice of poor clarity, which is recycled for further purification.
Purification
4. With light scale, the evaporator can be operated over a 9-12 day period. With
moderate scale, it can be operated over a six to nine day period, while with heavy
scale , it can be operated over a four to six period.

6. Affination: Treatment of raw sugar crystals to remove a film of adhering molasses , achieved by
mixing sugar with a concentrated sugar serum and then centrifuging the magma with or without
water washings.
Brix : Measure of dissolved solids in sugar solution, liquor or syrup using a refractometer. For
solutions containing only sugar and water Brix = % of sugar by mass.
Carbonation: Process involving introduction of carbon dioxide gas in to limed juice to remove
colour and non-sugar solids.
Strike: Massecute as a complete boiling, all of which discharged from pan.
Supersaturated solution : In which sugar content in solution is greater than the sucrose in
solution.
Phosphatation : Clarification using phosphoric acid and lime in which non-sugar components
are removed by flotation.
Defecation: is a function of phosphate content of juice, a process for removal of coarse dispersed
solids from juice by formation of flocculants precipitate within juice. This precipitate not only
adsorbs color and colloidal matter, but carries away with suspended solids, carries down in
settling
Massecuite: The mixture of sugar crystals and syrup (mother liquor), obtained during
crystallization stage of sugar refining.
