Sugar is produced the following way. Cane stalks are ground in a roller mill. This juice is clarified (filtered) and concentrated from 15% solids to 45% solids. This solution is then placed into pan evaporator and allowed to further slowly concentrate while at the same time it crystallizes. Further crystallization, at about 80-90% solids, continues in slowly agitated tanks. Finally, these crystals are dropped into a centrifuge and the molasses surrounding the crystals are "spun off". The resulting sugar is called raw sugar or natural brown sugar or Turbinado sugar (a main line product is called "Sugar in the Raw").
This sugar is then shipped to a sugar refinery. The sugar is further refined (i.e. molasses is spun off and the sugar is whitened). This white sugar is common table sugar.
