Fecha de publicación: -- Fuente: WIPO "olive oil" A droplet formation device 1 includes: a base member 2 formed of stacked substrates including a middle substrate 21 and a lower substrate 23; a passage structure 211 formed on the middle substrate 21 and including droplet formation passages through which a liquid dispersed-phase material and a liquid continuous-phase material flow to form droplets of the dispersed-phase material using a shear force of the continuous-phase material; a liquid storage part 231 formed on the lower substrate 23 and storing the liquid dispersed-phase material 200 and the liquid of the continuous-phase material 100; dispersed-phase material supply parts through which the liquid dispersed-phase material 200 is supplied from the liquid storage part 231 to the droplet formation passages of the passage structure 211; and continuous-phase material supply parts through which the continuous-phase material 100 is supplied from the liquid storage part 231 to the droplet formation passages of the passage structure 211.
