Particle Size Engineering Using Top Spray and Bottom Spray Congealing: A Technical Comparison and Practical Insights

This white paper provides a focused analysis of top and bottom spray congealing methods for particle size engineering in lipid-based formulations, addressing critical considerations for technical directors and engineers. By comparing these configurations, the paper illustrates how each method aligns with specific product requirements, such as particle uniformity, release rates, and scalability.


Top spray congealing produces smaller, consistent particles suited for rapid-release applications, making it ideal for precision dosing. Bottom spray congealing, meanwhile, supports high-volume production with larger particles designed for sustained release, beneficial in formulations that require gradual ingredient delivery.


With practical comparisons, process insights, and industry case studies, this white paper is a valuable resource for professionals looking to refine particle engineering processes.
