8. A method for producing cellulose beads comprising:
(Step 1) preparing a coagulating bath having a first liquid medium phase and a second liquid medium phase;
(Step 2) forming a particulate cellulose solution in the first liquid medium phase by supplying a cellulose solution to the first liquid medium phase of the coagulating bath; and
(Step 3) coagulating the particulate cellulose solution by supplying the particulate cellulose solution in the first liquid medium phase through gravitational force to the second liquid medium phase to produce coagulated cellulose beads;
wherein said cellulose solution has low miscibility with respect to said first liquid medium phase; and
wherein said coagulated cellulose beads have a particle diameter of 10 μm to 300 μm.
