Melt Suspension Crystallization (MSC) is a technique, that can be used for large scale separation and ultrapurification of organic compounds. Because of the high selectivity of crystallization, the moderate operating conditions, and the relativ ....

... have to be formed. The operation of crystallization is exacting. Large—capacity evaporators are not suited to the careful control and flexible manipulation required for a successful ‘strike’, or actual crystallization, of solid sugar . For this purpose, the concentrated liquor is transferred from the evaporators to the ‘pan.’ The pan is essentially a simple vacuum evaporator in which the removal of water continues until the concentration is appropriate for crystallization. As this proceeds, juice continues to be drawn into the pan in order to maintain a supply of crystallizable sugar. The concentration of impurities increases in the syrup ...
