ABSTRACT:
A method for producing cellulose beads which are high in sphericity and narrow in bead size distribution. Cellulose beads are produced by supplying a cellulose solution into a rotating vessel which is rotated at high speed by a rotary shaft and has outlets such as small holes and nozzles, flying droplets formed under a centrifugal acceleration of 10 to 1000 G through the outlets that have a diameter of 0.1 to 5.0 mm, and capturing the droplets with a coagulating solution to coagulate the droplets.
