The manufacturing of sugar begins when harvesting cane is received and cane is weighed on the plat form type weighbridges. The shredded cane is fed through the series of crushing mills to extract the sugar juice, which is then pumped away for further processing. The remaining fiber is called bagasse. The juice from the milling train contains impurities including soil, which must be removed for further processing. The juice is heated to about 70 degree centigrade in rapid flow vertical juice heater to maintain good co-efficient of heat transfer. The heated juice is limed and sulphsited in a continuous juice sulphiter, and then heated to 105 degree centigrade. The heated juice passes through a clarifier where the impurities precipitate and settle to the bottom as mud. The clarified juice is concentrated to syrup by boiling off excess water in a series of connecting vessel Concentration of the syrup from the evaporator is continued in vacuum pans. Very small seed crystals are introduced to the concentrating syrup and these begin to grow in Size. The sugar crystal is separated from the syrup in centrifugal machines. The moist raw sugar is dried in a steam of air and transformed to bulk storage bins

[...] Excess bagasse is stored in the bin for further use BOILER STATION The boiler station is the heart of a mill where steam is generated at many tones per hour. Often a mill can produce additional electricity that is sold to the electricity generating board. BY PRODUCTS SUGAR After crushing the sugarcane, the cane juice is accumulated in the juice tank, by adding chemicals and boiling it to temperature of 100-102 degree Celsius, process will take place during the boiling, then the sugar crystal are separated from the mother liquor with the help of massecuite. These sugar crystals contain sugar and oxygen. [...]

[...] The plant has a licensed capacity of 3600 metric tones per annum. Acetic acid is manufactured here by the Double Oxidation process with a purity of BAGASSE: Bagasse is the by-product, left behind after crushing of sugar cane. It is used as a fuel in the sugar factory boilers. Excess bagasse finds use as a raw material in paper manufacture. At present excess bagasse is used as raw material in co-generation plant to produce high efficiency electricity. PRESS MUD: Press mud is the bi-product generated [...]
