The diagram illustrates how sugar is manufactured from sugar cane. Overall, the sugar production requires four main stages including farming, extracting, processing and drying.

Looking at the farming and extracting stages, it starts by planting sugar canes and growing them in 12 to 18 months. Then, they are harvested either by agricultural vehicles or by hand. At the third stage, sugar canes are passed into a crusher machine and juice is extracted. Next, the juice is introduced into a to eliminate and become pure juice.

Turning to the other stages, the pure juice is boiled at high temperature in an evaporator to remove water and condenses into syrup. In the next stage, the syrup is poured into a centrifuge and spun at high speed to sugar crystals from it. At the final stage, the crystals are dried and cooled in a large container to produce finished sugar.
