PROBLEM TO BE SOLVED: To provide a resin drying method improved in productivity in resin feeding and resin molding. SOLUTION: In the resin drying method, an injection molding apparatus dries a resin in conjunction with resin molding, and feeds a resin molding machine with the dried resin according to the resin molding of the injection molding apparatus. The resin drying method includes steps of: putting a resin to be dried into a drying tank, a step to reduce the pressure in the drying tank; heating the resin in the drying tank; feeding the resin dried in the drying tank into the injection molding apparatus; and refilling the drying tank with the resin to be dried.
