Abstract

Process for free-flowing powdered solids of high-saturation hygroscopic For example, pure-net sugar or star hydrolyzate contains Heating the substance Dissolve in water with a concentration of substance up to a temperature higher than its normal boiling point under positive pressure. And spray solution Into the zone maintained at a temperature and pressure lower than the solution, which A stream of air or other inert gas flowing through

Claims (1)

1. The process for producing free-flowing resulting solids of a substance with a low softening point and / or hygroscopic, characterizes a) a) concentrated aqueous solution of such a substance is heated. Reaches a temperature higher than its normal boiling point under positive pressure; b) a concentrated aqueous solution that is heated and pressure It is sprayed into a region where a current of air or other inert gas flows through it, accurately maintained at low temperatures and pressures. Than solution by which the concentrated solution was heated and The pressure had exploded.
