The hot air will float into a collecting hood in the drying box, then enter the circulation pipe, and finally return to the heating box to continue heating and transportation, thereby completing the circulation purpose. This method can realize circulation heating inside a sealed space, improve drying efficiency, and solve the problems raised in the above-mentioned background technology.
