What is Sugar
Sugar is a broad term applied to a large number of carbohydrates present in many plants. The primary sugar, glucose, is produced by photosynthesis that done by all green plants. In most plants, the sugars occur as a mixture that cannot readily be separated into components. Economically appropriate plants are sugar beets and sugar cane which are rich in pure sucrose.
Raw materials for sugar
• Sugar cane
Sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, typically three to four metres high and about 5 cm in diameter The stems grow into cane stalk, which when mature constitutes approximately 75% of the entire plant. A mature stalk is typically composed of 11–16% fiber, 12–16% …show more content…

This is done using lime.
(g)Thin juice is reduced to thick juice
• The sugar juice, now a thin, pale yellow liquid, is called thin juice.
• The juice is placed in an evaporator, which boils away the water to make the juice thicker.
• The resulting liquid, called thick juice, contains approximately 70% sugar.

(h)Crystallisation
• The thick juice is pumped to large boiling stations, where tiny sugar crystals form in it.
(ı)Centrifugal spinning
• The thick, brown juice, which is now called massecuite, is spun in a centrifuge to separate the white sugar from the brown syrup.
• The syrup is returned to the boiling station and boiled again until there is no more sugar left to extract. (j)Molasses
• The remaining product is called molasses.
• Its sugar content is too low to yield any more sugar. Molasses is used for making animal feed, yeast and spirits
(k)Ready for use
• Finally, the sugar is dried and stored in a silo.
• The silos are completely full after the beet campaign, but will gradually be emptied during the year as the sugar is sold to shops, industries and on
