The diagram elucidates the multifaceted manufacturing process of sugar derived from sugar cane, encompassing seven distinct stages, from cultivation to the final product.
Overall, the process initiates with the growth of sugar canes over a duration of 12 to 18 months and culminates in the drying and cooling of sugar crystals, which ultimately yields raw sugar.
Initially, sugar canes are cultivated, a phase that typically spans 12 to 18 months. Upon maturation, the canes are harvested through mechanised or manual methods. They are then dispatched to a milling facility where the crushing process occurs, facilitating the extraction of the juice. Subsequently, this juice undergoes purification via a limestone filter, effectively eliminating impurities to produce a clean liquid ready for further processing.
Once purified, the juice is evaporated in a controlled environment to attain a syrupy consistency. This syrup is then subjected to centrifugation, a rapid spinning process that separates the sugar crystals from any residual liquid. In the concluding phase of the process, the extracted sugar crystals are dried and cooled, culminating in the production of raw sugar that is ready for refinement and consumption.
