Spray Drying Technique. I: Hardware and Process Parameters

The spray drying process comprises three major phases. The first one is the atomization of the liquid stream by an appropriate device. Next, fine droplets of the feed are subjected to the interaction with a drying gas at adequate (usually higher than feed) temperature. During this drying phase, the solvent contained within the dispersion ...
