Claim 7:
8. The method for drying polyolefin-containing particles according to claim 7, performed by setting conditions such that
drying time in the preliminary drying step is at least 0.01 times drying time in the drying step,
a particle temperature in the preliminary drying step is at least 0.5 times a particle temperature [K] during drying in the drying step, and
a ratio of an amount of the drying gas to an amount of the particles supplied in the preliminary drying step (amount of drying gas [kg]/amount of particles [kg]) is at least 0.1 times a ratio of the amount of the drying gas to the amount of the particles supplied in the drying step (amount of drying gas [kg]/amount of particles [kg]).
