Concentrates of baby food, whole-milk and skim-milk are spray dried to produce agglomerated powders having low content of grains as defined herein. High-quality products are obtained by avoiding re-wetting process steps by using flexible internal filters delivering a compact flow of fine particles to the section in the lower portion of the spray dryer where the possibilities are optimal for contact with moist particles of suitable moisture content and the risk for contact with wet droplets and hot drying air is small.
