摘要： A method of preparing dry core-shell microcapsules from an aqueous dispersion of such capsules, comprising spraying the dispersion through a two-fluid air-liquid nozzle into a heated chamber having an upper part and a lower part, the spraying taking place in the upper part and the lower part being provided with a means of continuous capsule removal. The method allows the drying of capsules with considerably reduced losses.
