A driving section is provided for a housing. A fan is rotated in the
housing by the driving section. Saturated steam, which is supplied to the
housing, is separated into a liquid component and a gas component by
applying the centrifugal force to the saturated steam by the fan to make
the saturated steam pass through a cylindrical separating wall. The
liquid component is discharged from an outlet port of the housing by the
separating wall and a shielding section. On the other hand, the gas
component is discharged from a discharge port formed at an upper portion
of the housing.
