The diagram illustrates the process of producing sugar from sugar cane, which involves seven main stages, from planting the cane to the final product.
Firstly, sugar is derived from sugar cane, which takes between 12 to 18 months to grow. Once it is fully grown, farmers harvest the plant either by hand or using a tractor, with the second method being preferred due to its ability to harvest the plant on a larger scale. In the next stage, the sugar cane branches are crushed by a machine to extract the sugar juice. The juice is then purified using a limestone filter. After that, the juice is heated up in an evaporator to reduce its water content until the syrup is produced.
During the sixth stage of sugar production, the syrup is sent to a centrifuge machine. This machine separates the sugar crystals from the syrup. The sugar crystals are then dried and cooled to become sugar. Overall, the diagram provides a clear representation of the complex process involved in making sugar, which requires various stages and equipment.
