PARTICLE DRYING APPARATUS AND METHODS FOR FORMING DRY PARTICLES

摘要

A novel multistage particle dryer is disclosed for producing dry particles. The dryer is capable of forming particles with a low residual content of volatile material, suitable particle sizes and a solid, spherical morphology. The disclosed methods and equipment can be used to generate microparticles in an enclosed sanitizable environment with desirable product attributes in a rapid single-step operation, obviating the need for secondary drying.
