Abstract
A rotating drum 3 has ventilation sections 6 that can ventilate the inside of the drum and the outside of the drum in the coating processing. To the ventilation sections 6, a panel unit 41 having arranged therein plural hollow pipes 42 through which cold water passes is attached. The hollow pipes 42 are fixed to a base plate 44 in parallel with each other, and a gap 'G' is provided between the adjacent pipes. The base plate 44 is provided with a communication hole 45, and the hollow pipes 42 are so arranged as to face the communication hole 45. To both ends of the hollow pipes 42, charge/discharge collecting pipes 46a and 46b are fixed. In the coating processing, cold water is arbitrarily supplied to the hollow pipes 42 through the charge/discharge collecting pipe 46a to cool the drum 3 so as to bring about the temperature difference between the inside of the drum and processing objects, which can prevent coating base materials from adhering to the inside of the drum.
