Abstract
Abstract Granular crystalline sucrose products are prepared from water solutions of sucrose containing noncrystallizable sugar, such as molasses. The sugar solution is subjected to partial crystallization to form a pumpable massecuite composed of microcrystals of sucrose dispersed in a water solution of the sucrose containing the molasses or other noncrystallizable sugar. The massecuite is sprayed into a drying air stream to form atomized droplets, and part of the water is removed to form granular aggregates of the sucrose microcrystals containing residual sucrose solution. The aggregates are aged and dried to form internally additional sucrose crystals and to further reduce water content. The products, comprising generally spherical granules formed of aggregates of microcrystals of sucrose, are characterized by being free-flowing and nonhygroscopic, and by rapid dissolution in water. The process is particularly adapted to the processing of partially refined cane sugar or beet sugar liquors to produce a brown sugar product of these characteristics.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
12 words
The granular crystalline sucrose product produced by the process of claim 1.
Claim 2
Dependent Claim
171 words
Process of preparing a granular crystalline product from a sucrose liquor composed principally of sucrose in aqueous solution with molasses, characterized by the steps of: a. subjecting said liquor to partial crystallization to form a massecuite composed essentially of microcrystals of sucrose dispersed in a substantially saturated water solution of sucrose containing said molasses, said massecuite being pumpable and sprayable; b. spraying said massecuite into a drying air stream to form atomized droplets containing a multiplicity of said sucrose microcrystals in each of said droplets and removing part of the water from said droplets in said air stream to form granular aggregates of said sucrose microcrystals therein containing residual portions of said sucrose solution and said molasses, the temperature of said air stream being controlled to limit the drying so that said aggregates on removal from said drying air stream contain about 2 to 5 percent water by weight; c. aging and drying the said granular aggregates to form additional sucrose crystals therein and to further reduce the water content thereof.
Claim 3
Dependent Claim
39 words
The process of claim 3 wherein said step ''''b'''' is carried out in a spray dryer, and said aggregates as formed in said spray prior to said step ''''c'''' contain total water of 2 to 5 percent by weight.
Claim 4
Dependent Claim
182 words
Process of preparing a granular crystalline product from a cane sugar liquor composed of sucrose in aqueous solution and containing molasses, said liquor containing about 15 to 25 percent water by weight, and a Brix of about 75* to 85*, characterized by the steps of: a. subjecting said liquor to partial crystallization to form a massecuite composed essentially of microcrystals of sucrose dispersed in a substantially saturated water solution of sucrose containing molasses, said massecuite being pumpable and sprayable; b. pumping said massecuite to a spray dryer and spraying said massecuite therein into a drying air stream to form atomized droplets containing a multiplicity of said sucrose microcrystals in each of said droplets and removing part of the water from said droplets in said air stream to form granular aggregates of said sucrose microcrystals therein containing residual portions of said sucrose solution, said granular aggregates as removed from said spray dRyer containing from 2 to 5 percent water by weight; c. aging and drying to said granular aggregates to form additional sucrose crystals therein and to further reduce the water content thereof.
Claim 5
Dependent Claim
147 words
Process of preparing a granular crystalline product from a water solution of sucrose containing from 1 to 6 percent by weight of noncrystallizable sugar, characterized by the steps of: a. subjecting said solution to partial crystallization to form a massecuite composed essentially of microcrystals of sucrose dispersed in a substantially saturated water solution of sucrose containing said noncrystallizable sugar, said massecuite being pumpable and sprayable; b. spraying said massecuite into a drying air stream to form atomized droplets containing a multiplicity of said sucrose microcrystals in each of said droplets and to remove part of the water from said droplets in said air stream to form granular aggregates of said sucrose microcrystals therein containing residual portions of said sucrose solution and noncrystallizable sugar; c. aging and drying the said granular aggregates to crystallize additional sucrose from said residual portions and to further reduce the water content thereof.
