PROBLEM TO BE SOLVED: To provide a drying device which dries a granular material for an injection molding machine without any concern about moisture reabsoption, can remove the gas generated from the material and further can apply an existing injection molding machine as it is, and also to provide a granular material-drying method and an injection molding system. SOLUTION: The drying device includes: a dry air generation apparatus 21 for generating the dry air having lower humidity than that of the atmosphere around the injection molding machine 1 to be blown into a cylinder 11 from the material supply port 111 of the machine 1; a resin supply apparatus 22 which controls the amount of a resin material to be fed from the material supply port 111 into the cylinder 11 according to the resin injection amount of the machine 1 and secures the flow path of the dry air between the melted resin in the cylinder 11 and the material supply port 111; and a control board 24.
