摘要： PROBLEM TO BE SOLVED: To provide a dryer wherein a dried resin pellet is sent to a molding machine without absorbing moisture in the air. SOLUTION: A dryer for a pellet is provided wherein the pellet 80 is casted from an inlet provided to an upper part of a hopper dryer 82, a nitrogen gas generated in a nitrogen generator 100 is circulated in the hopper dryer while a nitrogen gas generated in a nitrogen generator 100 is cast into the hopper dryer. Thereby, the pellet is dried, the pellet dried to a specific water content is discharged from an outlet 84 provided to a lower part of the hopper dryer and fed to a plastic molder 62. Since the nitrogen gas generated in the nitrogen generator is injected as a carrier gas into a material transporting pipe 66 wherein the nitrogen gas generated in the nitrogen generator is fed into the molder, or fed under pressure to a pressure feed hopper attached to the molder, and the dried granular plastic material neither adsorbs the moisture in the atmosphere, nor receives oxidation owing to the atmosphere on the way of being transported from the hopper dryer to the molder by the nitrogen gas.
