All of the previous refining processes have been carried out on liquors with a concentration of 60-65% (Brix). At this stage, an evaporator is used to remove some of the water prior to crystallization. The resulting syrup, which is known as evaporated liquor, is about 74% solid. The fine liquor is fed into large vacuum pans where sugar crystals are grown. Then, the syrup is heated indirectly by steam to about 80°C where it boils due to the vacuum applied to the vessel. The use of a vacuum and the resulting reduced temperature help minimize the Continue reading...
