Cane Sugar Manufacturing Video Lecture | Chemical Technology - Chemical Engineering

Cane sugar has been a sweetener of
choice for over two thousand years.
It is used in all types of foods due to
its versatility.
It enhances flavor, aroma, texture, and
browning.
It also helps retain moisture and
preserve freshness.
Sugar starts with sugar cane. A tall
tropical grass that can grow up to 20 feet high.
When it is ready for harvest the tops
are removed leaving the base stocks behind so they can grow into the next crop.
Sugar cane is a renewable resource that
doesn't have to be replanted to produce a new crop.
After harvesting and transporting to the
mill, the sugar cane is washed and cut into shreds.
Next, huge rollers crush the cane really really hard.
This mixture goes down to the separators,
where the fibers are removed and the juice is sent on to the evaporators.
Which are basically huge pots heated by
a furnace burning the dried sugarcane fiber.
How efficient is that?
The syrup is thickened by boiling off the water.
Once the syrup is cooled, it is time for it to be crystallized.
To get crystals from the syrup, it is seeded with, well crystals of sugar.
Just a sprinkle is enough to kickstart the process.
From there it is moved into centrifuges where centripetal force squeezes out any remaining liquid.
Leaving, you guessed it dry sugar crystals.
Now the crystals are purified, decolorized, recrystallized, and dried in a large granulator.
Next they are sized by running them
through a variety of screens all to remove any impurities and to make the sugar crystals just the right size and color.
The end result is pure cane sugar, no bleaching or added chemicals required.
Different types of sugar are created at
various steps in this manufacturing process.
Turbinado sugar has only been partially
refined and only the surface molasses washed off.
Brown sugar contains some of the surface molasses syrup which imparts that characteristic molasses flavor.
Granulated sugar is the last step in the manufacturing process.
Now that the sugar is ready, there is one final step before it can be packaged and shipped.
Every batch is tested in a lab to ensure
that it meets the highest standard of quality.
Because at Imperial sugar and Dixie
crystals we take great pride in turning pure cane into pure love.
