Abstract

PURPOSE:To prevent a mist in a fluid for treatment use from being generated and a foreign matter or the like from being caught by a method wherein a treatment chamber is connected to the outside via an interconnection port formed at one part of the treatment chamber and a vapor generated inside the treatment chamber is condensed at the outside of the treatment chamber. CONSTITUTION:A fluid 2 for treatment use inside a treatment chamber 1 is heated by a heating element 3; an atmosphere of a vapor 2a of the fluid 2 for treatment use is formed inside the treatment chamber 1; a heating lamp 8 is lighted; the inside of an opening 1a is heated at a prescribed temperature. The vapor 2a which has been formed inside the treatment chamber 1 and has risen to a height of an interconnection port 1b overflows into a cooling chamber 7 and is condensed on the surface of a cooling spiral pipe 7a; the inside of the cooling chamber 7 becomes a negative pressure; the vapor 2a continuously overflows from the treatment chamber 1 to the cooling chamber 7; an ascending stream of the vapor 2a displaying a laminar stream is formed inside the treatment chamber 1. A normal- temperature object 5 to be treated which has been housed in a transfer jig 6 is lowered inside the treatment chamber 1 through the opening 1a; it is kept at a standstill in a position which is lower than the interconnection port 1b and in an atmosphere region of the vapor 2a. By this setup, water or oils and fats which have adhered to the surface of the object 5 to be treated are replaced with liquid drops of the fluid 2 for treatment use; the replaced water or the like drops to the bottom of the treatment chamber 1 together with the liquid drops of the liquid 2 for treatment use and is removed.
