摘要： In preparing porous, uniformly granular sugar, which is substantially instantaneously soluble in water, an aqueous, concentrated, e.g. 80 to 95 percent by weight, solution of sugar having a temperature between 110 DEG and 130 DEG C. is agitated and cooled to normal temperature, e.g. between 15 DEG and 20 DEG C., to form a crop of fine, micro-size sugar crystals, which together with the mother liquor are mixed with a hydrophilic, volatile organic solvent, such as ethyl alcohol, methyl alcohol or acetone, and most of the resulting liquor is removed, as by centrifuging, to leave sugar crystals coated with a thin film of mother liquor mixed with the organic solvent. The coated sugar crystals are then granulated, e.g. screen-granulated, and dried to yield uniformly granular sugar according to the invention, e.g. having a granular size between 0.4 and 0.8 m.m., a bulk density between 0.4 and 0.5 g. per ml. and a water content between 0.04 and 0.06 percent, by weight. Alternatively, the mixture of sugar crystals, mother liquor and organic solvent may be spray-dried, or film-dried and pulverized or granulated.
