TIRE VULCANIZER

PROBLEM TO BE SOLVED: To provide a tire vulcanizer capable of improving productivity by reducing energy loss and thereby shortening a vulcanization time.SOLUTION: The tire vulcanizer includes a metal mold and a bladder, and carries out vulcanization while bringing the bladder into close contact with the entire internal surface of a tire by supplying a high temperature pressure medium into the bladder. The tire vulcanizer further includes a supply pipe which supplies the high temperature pressure medium to the bladder, a discharge pipe which discharges the high temperature pressure medium from the bladder, and a drain trap which is provided in the discharge tube and separates a drain included in the high temperature pressure medium from the high temperature pressure medium. The high temperature pressure medium discharged from the bladder is returned to the supply pipe after being separated from the drain by the drain trap, and the drain is discharged to the outside.
