Fine particle manufacturing device

An apparatus for producing fine particles, the apparatus comprising:

• a particle formation mechanism including a unit-structure, wherein the unit-structure includes:
• first and second portions adjacent to each other;
• a first inlet defined in the first portion at a first height, wherein a continuous phase solution is injected into the first inlet;
• a second inlet defined in the first portion at a second height different from the second height, wherein a dispersed phase solution is injected into the second inlet;
• a merging volume defined in the second portion adjacent to the first portion, wherein the merging volume is defined at third height, wherein the third height is equal to either the first height and the second height, or has a value between the first height and the second height, wherein the continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed via the merging between the continuous phase solution and the dispersed phase solution in the merging volume;
• and
• a first micro-channel and a second micro-channel branching from the merging volume so as to be in communication with the first inlet and the second inlet, respectively;
• and
• a particle-outlet micro-channel in communication with the merging volume in the particle formation mechanism, wherein the particle-outlet micro-channel is constructed to flow the fine particles formed from the merging volume in a first direction and discharge the particles to an outside of the apparatus,
• wherein the first micro-channel is in communication with a first sub-channel and a second sub-channel branched from the merging volume,
• wherein the second micro-channel is in communication with a third sub-channel disposed between the first and second sub-channels,
• wherein the continuous phase solution and the dispersed phase solution flow via the first to third sub-channels into the merging volume.
