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.
