The diagram delineates the seven-stage manufacturing process of sugar from sugarcane, beginning with its cultivation and the refined sugar product.
A glance at the illustration reveals that the process is raw sugarcane into a consumable product through a series of mechanical and chemical treatments, including crushing, purification, heating, and crystallisation.
The production cycle commences with the cultivation of sugarcane on farms, a process that typically spans between twelve and eighteen months. Once mature, the sugarcane is harvested, either manually or using machinery, and subsequently transported for processing. The initial processing step involves crushing the sugarcane stalks in a grinder, which extracts the raw sugarcane juice.
Following this, the extracted juice undergoes purification using a limestone filter to remove impurities. The purified juice is then transferred to an evaporator, where it is heated, leading to the vaporisation of water and the formation of a concentrated syrup. This syrup is then introduced into a centrifuge machine, which effectively separates the sugar crystals from the liquid. In the final stages, these newly formed sugar crystals are meticulously dried and cooled, culminating in the production of the finished sugar product ready for consumption.
