How sugar is produced from sugar cane
Sample Essay 1
The diagram displays how sugar is manufactured from sugar cane.
Overall, it is a man-made, linear process consisting of four main stages: farming, crushing, separating and drying.
The first step is to grow sugar cane and it takes about 12 to 18 months for it to mature. After it has fully grown, it is harvested either manually or mechanically. The manual method involves farmers removing the leaves first and then chopping the stalks, while the mechanized method uses machines to cut the canes directly.
The harvested canes are then crushed in a mill to extract the juice, which later on is purified using a limestone filter. Next, the purified juice is boiled in an evaporator to remove water so that it is concentrated into a syrup. The syrup is then poured into a centrifuge where it is spun at high speed to separate sugar crystals from it. Finally, the crystals are dried and cooled and the end result is sugar.

Overall, a total of seven steps is seen from the production, including harvesting, crushing and separating. It is also evident that manufacturing sugar from sugar canes is a capital-intensive process, despite using only one ingredient.
To begin, sugar canes take 1 to 1.5 years to grow before they are ready for harvest. This stage could be performed in two different methods, either manually using a sickle or by an industrial reaper.
Once collected, the sugar canes are machine-pressed in order to extract the juice. This juice is then passed through a filter made of limestone so that any unwanted substance is eliminated. The next stage involves evaporation, in which the filtered sugar cane juice is put under heat and therefore thickens into a syrup. Subsequently, the syrup is transferred into a centrifuge, which rotates at a very high speed so that sugar crystals are separated from the liquid due to differences in density. In the final step, the sugar is dried and cooled, ready for packaging and sale.

The diagram illustrates how sugar is produced from sugar cans.
As clearly can be seen, there are seven various stages in this process demanding specific machinery and skilled workers.
First of all, sugar needs to be grown in appropriate farmland. After passing 12 to 18 months (perhaps depending on the culture conditions as well as the types of sugar can), the crops are harvested either mechanically by trucks or physically by farmers. At the next step, sugar cans enter into a machine with two rotating wheels in which sugar is completely crushed so that its juice is extracted.
Subsequently, the extracted juice is passed through a limestone filter forpurification. While the purified juice is being heated, its liquid evaporates. Therefore, the juice becomes syrup. At this point, a centrifuge is needed to separate sugar crystals from the syrup. Once the syrup has been centrifuged for a certain time, it is eventually dried and cooled in big containers. The final substance is a substance which is called sugar.
