摘要:
A particulate material production apparatus (1) is disclosed. The particulate material production apparatus (1) includes a droplet ejector (2; 105) to eject droplets of a particulate material composition liquid or a melted particulate material composition in a droplet ejection direction from nozzles (19); a solidifying device (60) to solidify the droplets; a first airflow forming device (7) to form a first airflow to feed the ejected droplets to the solidifying device (60) with the first airflow; and a second airflow forming device (108; 108-2, 106;108-3, 106; 108-4) to form a second airflow to apply the second airflow the droplets before the droplets are fed by the first airflow. The second airflow forming device (108; 108-2, 106;108-3, 106; 108-4) forms the second airflow by supplying a pressed gas from a slit (103), and the traveling direction of the first airflow is substantially perpendicular to the droplet ejection direction.
