DEVELOPMENT OF ANTI-AGGLOMERATION METHODS FOR DRY POWDERS
Abstract
A technique was developed for successfully spraydrying saccharin and para-aminobenzoic acid from solvent systems of 70% acetone, 30% carbon tetrachloride. Particle sizes less than 10 microns in diameter were achieved. Incorporation of an antistatic agent, Catanac SN, markedly increased the flowability of the powders. A spray-dryer was designed and constructed with sufficient adaptability and simplicity to permit evaluation of various atomization devices (spinning disk, centrifugal pressure nozzle, impingement and pneumatic nozzles), hot-gas spray mixing procedure, powder collection and separation equipment.
