The given illustration provides a whole process of sugar production, from growing sugar cane to the finished product.
Overall, a total of 7 steps are presented, including harvesting, crushing, purifying, evaporator, centrifuge, and cooling. It is evident that making sugar from farm produce is quite complex, despite using only one ingredient and requiring less human involvement.
In the first stage, only matured sugar canes, which take from 12 to 18 months to fully grow, are selected. After being harvested by farmers, with support from modern equipment, those sugar canes are put into a crushing machine to separate liquid from the dry part. Next, limestone is used to filter the juice, removing all the remaining sugar cane’ meat. In the fifth step, sugar syrup is made by boiling the juice directly under the heat, forcing evaporation interaction to occur. Once the liquid turns into a thicker form, sugar crystals are extracted from the syrup, which is called the centrifuge process. The final step is to let the sugar cool down.
In conclusion, the diagram reveals a completed operation of how manufacturers make sugar from scratch.
