Abstract
Sugar is crystallized from aqueous solutions thereof by spraying a supersaturated sugar solution or syrup at elevated temperature into a high velocity air stream, at ambient temperature, whereby crystallization and drying occur rapidly and the sugar crystals are entrained in the air stream and carried away from the spray zone in pneumatic transport.
Claims7
Method for crystallizing sugar from a super-saturated syrup of a crystallizable sugar, the syrup having a total solids content of at least 75 weight percent, and the syrup having a crystallizable sugar content of at least 85 weight percent of the total solids in said syrup, which comprises spraying said super-saturated syrup at elevated temperature greater than about 250.degree. F. in the form of droplets of syrup having sizes of from about 50 to 500 microns, into a flowing gas stream having a temperature of less than about 200.degree. F., whereby droplets of syrup crystallize to form solid sugar particles, and removing said droplets and crystallized solid sugar particles from the spray zone by pneumatic transport in said gas stream.
