Abstract
A method for producing resin particles includes drying resin particles in a wet state by passing, without circulating, the resin particles through a drying tube together with a first gas, the resin particles being ones that undergo pressure-induced phase transition. The drying tube has an inlet through which the resin particles are fed into the drying tube, at least one gas blowhole through which a second gas is blown over the resin particles passing through the drying tube, and an outlet through which the resin particles are ejected from the drying tube, and the second gas is blown out of the gas blowhole at a velocity of 50 m/s or more.

A method for producing resin particles, the method comprising:
- drying resin particles in a wet state by passing, without circulating, the resin particles through a drying tube together with a first gas, the resin particles being ones that undergo pressure-induced phase transition, wherein:
- the drying tube has an inlet through which the resin particles are fed into the drying tube, at least one gas blowhole through which a second gas is blown over the resin particles passing through the drying tube, and an outlet through which the resin particles are ejected from the drying tube;
- and
- the second gas is blown out of the gas blowhole at a velocity of 50 m/s or more.

- and
- a difference Δ(V2−V1) is 40 m/s or more, where V1 is a velocity of the first gas passing through the drying tube, and V2 is a velocity of the second gas blown out of the gas blowhole.
