Abstract
Agglomeration is improved in a straight-through spray drying process by adjusting the location for introduction of recycled fine particles to the atomization zone. The fine particles are dispersed in a minor portion of the drying air and adjustment of the location for the introduction of the fine particles is made so as to change the average distance from the wheel to the area where the fine particles meet atomized droplets or partly dried particles. A spray drying apparatus in which the fine particles are recycled through the use of turnable deflectors, telescopic connections or swivel joints which are suitable for achieving the improved agglomeration.
