How Is Sugar Made?


Quick Answer

The production of sugar involves boiling the juice of sugar beets or sugarcane to crystallize the sugar. Spinning, perforated, metal baskets isolate the crystals from the syrup, and dryers evaporate excess water and cool the sugar.

To make sugar from sugar beets, the manufacturer washes and slices sugar beets before boiling them in water and filtering out the impurities. The continuous boiling creates a thick syrup and causes the sugar to crystallize, and the machine proceeds to spin the mixture quickly with hot water to separate out the molasses. The manufacturer then dries the sugar. The leftover sugar beet pulp is suitable for use as animal feed.

To make sugar from sugarcane, the manufacturer follows a similar but less-continuous process, which begins by crushing the sugarcane and boiling the juice to make a thick syrup that eventually results in the crystallization of the sugar. The machine spins the sugar crystals and discards some of the molasses to create raw sugar. The leftover sugarcane pulp, also known as bagasse, is suitable for use as biofuel and can serve as an important energy source for the sugar factory.

The manufacturer delivers the raw cane sugar to the refining facility. Here, machines strain the sugar to remove impurities, then spin it quickly with water to filter out the remaining molasses before dehydrating the crystals, thereby creating white sugar.
