The diagram illustrates the phases to produce sugar from sugar cane plant.
Overall, the production of sugar involves seven stage process, that begins with growing the sugar cane in farms and culminates in drying and cooling the syrup to form sugar.
In the first step, the sugar canes are grown in farmland for about a year to 18 months and then the mature plant is harvested either manually or with the help of agricultural machinery. After that, the sugar cane stalks are crushed in a grinder, resulting into formation of sugar cane juice.
In the next step, the juice is purified by going through a limestone filter. Subsequently, the juice is heated in an evaporator and by vaporization of water it becomes a syrup. The syrup is then poured into a centrifuge where it separates sugar crystals from syrup. Finally, the sugar is produced by drying and cooling the crystals.
