ABSTRACT:
[Method for drying crystallized sugar in the presence of a heated environment, wherein said environment has a relative humidity less than, but close to the equilibrium relative humidity of the sugar to be dried, at the temperature of the environment. This method permits crystallized sugar to be obtained in bright crystals and to exhibit physical characteristics similar to those of products produced by the Adant method, such as hardness, resistance to abrasion, porosity, rate of dissolution, and density.]
A method for manufacturing elements of crystallized sugar, such as lumps, slabs and loaves thereof, comprising the steps of moistening the crystallized sugar, molding and compressing the sugar into elements and then drying the elements at a drying temperature wherein the molding and compression of said moistened sugar are carried out at said drying temperature and in an environment which during said drying has a relative humidity less than 100% but more than 85% of the equilibrium relative humidity of the sugar at said drying temperature. This method permits elements of crystallized sugar to be obtained having bright crystals and exhibiting physical characteristics similar to those of products produced by the Adant method, such as hardness, resistance to abrasion, porosity, rate of dissolution, and density.
