Abstract
A method for forming dried, solid, particulate product from complex sugar solutions by drying the solution in a current of heated air and in the presence of separately introduced recycled dried solids which have undergone additional conditioning to have a moisture content of not greater than about 0.5 percent therein.
Claims3
A process suitable for drying complex sugar solutions to form stable, solid, particulate product therefrom comprising
- (a) drying in a drying zone dispersed complex sugar solutions in a current of heated gas and in the presence of from about 1 to 10 parts by weight of separately introduced recycled conditioned solids per part by weight of solids in solution to produce a solid product;
- said heated gas has an inlet temperature of from about 100 to 300 degrees C. and an outlet temperature of from about 60 to 120 degrees C;
- (b) contacting in a conditioning zone the formed solid product with a conditioning gas having a humidity of less than 50% and having a temperature below the melting point of the formed solid for a time sufficient to reduce the water content of said solids to not greater than 0.5 percent;
- and (c) recycling a portion of said conditioned solids to said drying zone to be used as said recycled solids in step (a).
