Project Details : Carried out detailed engineering, manufactured equipments, procured balance plant & machinery, supervised construction & successfully commissioned the plant.

Sugar Production Process

• Sugar cane harvested from fields is chopped, beaten into fibers and pressed and crushed in roller mills to extract juice.
• The fibers ejected from mills, known as bagasse, is burnt in boiler to raise steam of about 45 kg /cm2 .
• The steam is fed into back pressure turbine which drives alternator to generate electric power ( AC, 3 phase, 415 V , 50 cycles), which is utilized in driving various equipments in the plant.
• The exhaust from turbine which is around 1.2 kg / cm2 pressure, provides heat for evaporating water from sugar cane juice.
• The thickened juice is cooled to allow formation of sugar crystals, which are separator in centrifuges. The crystals are washed and dried, and sugar is bagged for sale.

By Products of Sugar

• The sugar cane fibers from which juice has been extracted and ejected from the mills is known as bagasse.
• The quantity of bagasse generated is around one-third of the quantity of sugar cane crushed, and contains about 50% moisture.
• The bagasse is combustible and is used for producing steam. Excess bagasse is sold for producing newsprint etc.
• The other by-product is molasses, which is residue after sugar is separated from thickened syrup. The quality of molasses generated is around 4% of the quantity of cane crashed.
• Molasses is utilised for producing alcohol, which can be refined to suit the end use (potable alcohol for human consumption or ethanol for blending with petrol.)
