Zusammenfassung:	PURPOSE:To granulate a stock powder in a particle size and strength controllable manner in good efficiency, by a method wherein the stock powder is extruded from a screen under pressure and the extrudate is introduced into a drying zone while floated in a humidifying zone to form a granule. CONSTITUTION:When a stock powder is introduced from a hopper 1 and a screw auger 3 is rotated, it is extruded from a screen 4 as a particle with a predetermined particle size to be fallen into a humidifying cylinder 5. Because the particle is floated by steam from a steam blowing-out port 9, it is fallen into a particle chamber 15 while sufficiently humidified and dried to obtain an easily soluble granule. The particle size thereof can be controlled by replacing the screen and the strength can be also controlled by adjusting a humidifying time.
