Abstract

An expanded particle producing apparatus includes a vessel and a blade stirrer that is located inside the vessel. The blade stirrer comprises a stirrer base and an impeller blade that is attached to the stirrer base. A distance from the bottom of the vessel to the center of the stirrer base (L) and a depth of the vessel (L) have a ratio (L/L) of 0.01 to 0.2. Lis measured in a depth direction parallel to L, and a central axis of the blade stirrer coincides with a central axis of the vessel. The apparatus is configured to produce expanded particles.
