ABSTRACT:
A hydrophilic drying liquid such as isopropyl alcohol is evaporated and supplied to an object to be dried such as an electronic component. As the drying liquid is condensed on the surface of the object and flows down together with water adhering to the object, the object is dried. Water contained in the condensate is removed by means of a membrane-type separator disposed in the liquid or vapor of the drying liquid. A rise in the water concentration in the drying liquid is prevented so as to maintain high drying efficiency.
