Abstract:
1. A method for producing resin particles, comprising: ejecting, into a chamber, a liquid containing at least a resin in the form of droplets from a droplet ejecting unit having a plurality of holes provided in a part of a flow channel for feeding the liquid containing at least a resin, wherein a plurality of the droplet ejecting units are arranged in a side wall of the chamber to eject droplets toward the center of the chamber, and wherein at least a portion of the liquid containing at least the resin fed from a liquid container to the droplet ejecting unit is circulated between the liquid container and the droplet ejecting unit and back to the liquid container; and drying and solidifying the ejected droplets so as to obtain the resin particles, while the ejected droplets are transported by a primary transport air flow flowing in the direction in which the droplets are ejected, wherein the ejected droplets are further transported by a secondary transport air flow which transports the ejected droplets in a different direction from a direction in which the primary transport air flow flows, wherein the secondary transport air flow flows from upside to downside, and wherein a smaller angle of angles formed between a velocity vector of the primary transport air flow and a velocity vector of the secondary transport air flow is less than 120 degrees.
