PROBLEM TO BE SOLVED: To produce concrete products of high quality with a low cost installation by jetting forced-fed steam through a mist ejector made of a woven fabric or knitted fabric into an aging chamber and creating a homogeneous mist atmosphere in the aging chamber to increase the aging effect. SOLUTION: The steam that is force-fed from a steam boiler through an extended steam tube 12 and is ejected through a mist ejector 10 of a hose-shaped woven fabric or knitted fabric into an aging chamber. When it passes through microfine weaving or knitting eyes, the steam flow rate is suppressed and becomes ultrafine mist or fogs and an atmosphere suitable for aging is built up in the chamber and a concrete product of uniform and high quality is produced. The mist ejector 10 made of the knitted or woven fabrics can also be used in room ventilation and a pleasant atmosphere space can be formed by setting the mist ejector 10 to an outlet for cool air or warm air to remove the cool wind feel irritating the skin. |
