The process diagram illustrates the manufacturing of sugar from sugar cane. There are seven stages in total, including growing, harvesting and crushing, and other fine production stages.
The initial stage is to grow sugar canes which usually takes 12 to 18 months to mature. When they are ready to be harvested, machines collect canes and farmers chop and bundle them to for the next step – crushing. Bunches of sugar canes are put into a squeezing machine to be extracted into juice.
Afterwards, the collected juice will undergo four stages of fine processing. The fourth stage is to purify juice in a limestone filter into purified liquid, which is further transformed into syrup through heating in an evaporator in the fifth stage. Subsequently, syrup crystals are separated from syrup in centrifuge. After the final stage of drying and cooling, sugar is produced.
