The diagram illustrates the sequential stages involved in the production of sugar from sugar cane. Overall, the process encompasses seven distinct steps, beginning with the cultivation of the sugar cane and culminating in the drying and cooling of the sugar crystals.
Firstly, sugar cane is cultivated over a period of 12 to 18 months until it reaches maturity. Once mature, the cane is harvested, either manually using traditional tools or mechanically with specialized machinery. Following the harvest, the sugar cane undergoes a crushing process where it is mechanically pressed to extract the juice.
The extracted juice is then purified by passing it through a limestone filter, which removes any impurities. Subsequently, the purified juice is heated in an evaporator to transform it into a syrup. This syrup undergoes further processing in a centrifuge, which separates the sugar crystals from the remaining liquid.
The final step involves drying and cooling the sugar crystals. This process ensures that the sugar is in a suitable condition for packaging and consumption.
In summary, the production of sugar from sugar cane involves a series of methodical steps that include cultivation, harvesting, crushing, purification, evaporation, centrifugation, and finally, drying and cooling. Each stage is essential in transforming raw sugar cane into refined sugar ready for use.
