Band 9: The diagram below shows the manufacturing process for making sugar from sugar cane. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram gives detailed information about the process in which sugar is produced from sugar cane.

Overall, it is clear that there are 7 main stages in the production of sugar, starting with growing sugar cane for about 12 to 18 months and culminating with drying and cooling it in a special machine. It is also worth mentioning that the process requires both labor-intensive and machine-driven jobs, the latter taking up most of the work.

Looking at the details, the process begins when sugar cane is grown (12-18 months). Next, it is harvested in two different ways (by machine or by hand). After harvesting the sugar cane, it is crushed by a special machine to get juice. Then, it is sent to the next stage where a limestone filter is applied to purify the juice. Having been filtered, the juice is heated until it becomes syrup in a process called evaporation. After that, another process called centrifugation (which separates sugar crystals from syrup) is applied. At the end of the process, the sugar is dried and cooled in a container.
