Disclosed a microsphere-producing process involving three integrated unit operations: 1) microspheres formation; 2) microspheres quality control; 3) post formation microspheres treatment. The first unit operation is integrated with four essential functions: forcing the particle forming materials to pass through a porous membrane to form embryonic microsphere; enforcing the embryonic microspheres to detach the porous membrane; solidifying the embryonic microspheres; collecting and outputting the solidified microspheres. The quality control unit operation consists of discrimination and ejection of oversized microspheres. The post treatment unit operation is integrated with two essential functions: smoothing the microsphere surfaces and reducing organic solvents trapped inside of microsphere matrix. |
