METHOD TO IMPROVE CHARACTERISTICS OF SPRAY DRIED POWDERS AND GRANULATED MATERIALS, AND THE PRODUCTS THEREBY PRODUCED

摘要

A method for preparing solid materials is described. One aspect of the method includes the steps of providing a mixture comprising an organic material in a blend of a solvent and non-solvent for the organic material, distributing the mixture into either droplets or granules, and evaporating the solvent and non-solvent mixture to form particles having an average size of from about 0.5 µm to about 5000 µm.
