<p>PROBLEM TO BE SOLVED: To provide a particle manufacturing apparatus capable of manufacturing particles having a narrow particle size distribution while suppressing a temperature rise of discharge hole surfaces brought into contact with transportation air flows, and further to provide a particle manufacturing method.SOLUTION: A particle manufacturing apparatus comprises: air flow passage formation means; droplet formation means 11 having a plurality of discharge holes 19 on a flat surface, discharging resin composition liquid 14 containing resin and solvent into air flow passages through the plurality of discharge holes 19 and forming droplets 21; air flow supply means supplying transportation air flows 41 having a high temperature into the air flow passages such that the air flows 41 flow in a direction parallel with a surface direction of discharge hole surfaces; and particle collection means 70 collecting particles dried and solidified in the transportation air flows having the high temperature. The air flow supply means supplies first transportation air flows supplied such that the first transportation air flows flow while being brought into contact with the discharge hole surfaces and second transportation air flows being supplied such that the second transportation air flows flow at opposite sides to the discharge hole surfaces with the first transportation air flows interposed thereamong and having a higher temperature than that of the first transportation air flows into the air flow passages.</p> |
