Cane Sugar
is made out of
sugar cane which is grown in the tropics. Sugar cane contains up to 20
per cent of sugar in its stems. In order to reach this sought after raw
material, the sugar cane is pressed in a grinder. The yielded juice
which contains the sugar is, however, also somewhat polluted. These
nebulas are bound with the help of the addition of chalk and carbon
dioxide and are then separated from the sugar fluid through filtering.
With this procedure, the sugar juice is cleansed and, by adding sugar
syrup, it is thickened and, thereby, crystallised.
This crystallisation process is relatively quick. The remaining syrup
is separated from the crystals via centrifugation. The cane sugar is,
however, still yellow-brown coloured due to the syrup residue which is
still sticking to it. These are finally removed from the sugar crystals
by washing them and employing steam to clean them. After this process,
the cane sugar is, again, dissolved and crystallised. It is only now
that the snow-white sugar is received, the refined sugar.
