The diagram explains the process of producing sugar from sugar cane in seven main stages, beginning with the growth of the plant and ending with the final drying and cooling of sugar.
Overall, the production requires both farming and factory steps. It starts with planting and growing sugar cane for over a year and finishes with refined sugar that can be packaged and used for daily consumption.
First, sugar cane is grown for about 12 to 18 months until it is ready to harvest. The crop can be collected either manually, using knives, or by machines. After harvesting, the canes are crushed in order to release the juice from the stalks.
In the next stage, the juice is filtered with limestone to remove any dirt or unwanted materials. Then it is boiled in an evaporator, which reduces the water and produces thick syrup. After that, a centrifuge separates the syrup into liquid and sugar crystals.
Finally, the crystals are carefully dried and cooled to produce the finished sugar product.
