Introduction:
Sugar industry is defined as industry which is involved in the production of edible sugar from raw sugar cane and sugar beet.
Sugar is extracted from two raw materials,sugar cane & sugar beet.
Both taste the same & produce white sugar.
Sugar industry is seasonal industry , season for sugar cane is 12 to 22 weeks and 6 to 12 weeks for sugar beet.
Different stages in manufacturing process:
a) Planting and harvesting
b) Preparation & Processing
c) Juice extraction process
d) Purification of juice:-
Clarification & evaporation
e) Crystallization
f) Centrifuging
g) Drying and packing
a) Planting and harvesting:
Sugar cane requires an average temperature of 24 degrees.
Black soil is essential.
The harvested cane stacks are loaded mechanically or physically into trucks or tractors & taken to factory for processing.
b) Preparation & Processing:
After the sugar cane is arrived at sugar factory,it is unloaded physically or mechanically by using cranes.
Then it is cleaned or washed.
Excessive soil are removed and the cane is ready to be milled.
c) Juice extraction process:
Heavily grooved crusher rollers break the cane & extract a large part of juice.
Revolving knifes cuts the stalk into chips are supplementary to the crusher.
The pressing process involves crushing the stalks between the heavy & grooved metal rollers to separate the bagasse.
As the cane is crushed, hot water (or a combination of hot water and recovered impure juice) is sprayed onto the crushed cane counter currently as it leaves each mill for diluting.
Extracted juice contains 95% or more of the sucrose present.
