Microsphere producing system and microsphere producing method

A method of producing microspheres, the method comprising:

• preparing a first raw material and preparing a second raw material including a biodegradable polymer, a drug, and a solvent;
• providing the first raw material and the second raw material to an emulsion generating part and continuously forming, by the emulsion generating part, an emulsion including the first raw material of a continuous phase and the second raw material of a dispersed phase;
• supplying a firstly generated emulsion of the emulsion continuously formed in the emulsion generating part to a first solvent extracting and removing part and extracting and removing, by the first solvent extracting and removing part, the solvent from the dispersed phase of the firstly generated emulsion to form a microsphere;
• and
• supplying a secondly generated emulsion of the emulsion continuously formed in the emulsion generating part to a second solvent extracting and removing part which is spaced apart from the first solvent extracting and removing part and extracting and removing, by the second solvent extracting and removing part, the solvent from the dispersed phase of the secondly generated emulsion to form a microsphere,
• wherein the secondly generated emulsion is an emulsion generated in the emulsion generating part after the firstly generated emulsion is supplied to the first solvent extracting and removing part.
