The given diagram details the process of producing sugar from sugar cane.
Overall, it is a linear process consisting of four main stages: farming, crushing, separating and drying.
The first step is to grow sugar cane and it takes 12 to 18 months for it to mature, which is the longest stage. After it has fully grown, it is harvested either manually or mechanically. The manual process involves farmers removing the leaves first and then chopping canes, while the mechanical process uses a specialized vehicle to cut canes directly.
Having been cut, the harvested canes are crushed to extract the juice, which later on is purified by using a limestone filter. Next, the purified juice is boiled in an evaporator to remove water, resulting in syrup. The syrup is then poured into a centrifuge where it is spun at a high speed to separate sugar crystals. The last stage is to dry and cool the crystals and the end product is sugar.
