The invention relates to the technical field of garment processing, in particular to a drying box for garment processing. The drying box comprises a base; a drying chamber is arranged at the upper endof the base, a top plate is fixedly connected to the top end of the drying chamber, one end of the top plate extends to the outside of the side wall of the drying chamber, a door is arranged on the surface of the side wall of the drying chamber, a conveying device is arranged at the lower end of the top plate, a clothes hanger is detachably connected to the conveying device, at least two groups of air inlets are formed in the surface of the top end of the base, the air inlets are connected with an air guide duct, and the air guide duct is connected with a hot-air blower. Through the setup ofthe conveying device, garments can be conveyed to the drying chamber in sequence without manual transfer, thus reducing the intensity of labor of the staff and improving the production efficiency; simultaneously, as the part, extending to the drying chamber, of a main rod is a polished rod, so that the garments sent out after being dried can be collected and picked up; and during garment drying, nut pairs are sequentially pushed to a screw rod end of the main rod, so that the garments can be separated, and the drying efficiency of the garments is improved.
