甘蔗制糖流程Manufacturing process for making sugar from sugar cane

The illustration summarises the different steps of producing sugar from sugar cane – starting from growing sugar cane and ending in making the final product, which is sugar. Overall, sugar cane plants get ready to be harvested for manufacturing sugar when they are a year to a year and a half old, and the sugar manufacturing process involves harvesting, crushing, making syrup, centrifuging, and finally drying and cooling. As the diagram depicts, sugar cane plants are harvested from the fields when they are between twelve and eighteen months old. They are harvested either manually by human labourers or by using machines. In the third step, these sugar cane stems are crushed in a crusher machine to produce juice. Afterwards, the produced juice is purified by a limestone filter before the juice is heated by an evaporator to produce syrup. Sugar crystal is separated from the syrup in a device called a centrifuge. The final step involves drying and cooling the produced sugar crystals to make the sugar that we consume.
