Abstract
A series of experiments has been conducted to investigate the origin of particle aggregation in a pilot-scale counter-current spray dryer. Various nozzle configurations have been designed to isolate the role of different sources of aggregation upon particle enlargement. Product particle size, water and active component/s distributions have been obtained. Particle aggregation is observed to have different origins, dependent upon the operational regime. In addition to the influence droplet coalescence within a spray has on particle enlargement, in this work other interactions as wall buildup and inter-nozzle aggregation are identified as relevant processes.
