METHOD FOR DRYING WOOD BY USING OVERHEATED STEAM, CAPABLE OF PREVENTING THE WOOD FROM DISTORTING OR CRACKS FROM GENERATING ACCORDING TO CHANGES OF HUMIDITY

摘要

PURPOSE: A method for drying wood by using overheated steam is provided to obtain eco-friendly wood materials as the wood are processed at high temperature by using overheated steam obtained by the water without chemical additives.;CONSTITUTION: A method for drying wood by using overheated steam comprises the following steps: laminating wood in a wood fixing jig (S1); inserting the wood fixing jig in which the wood are laminated into a wood drying chamber which is equipped with a temperature sensor, a pressure sensor, and a balance (S2); producing the saturated steam of 150 °C by a steam boiler (S3); producing the overheated steam by the steam boiler(S4); drying the wood with the overheated steam by supplying the overheated steam to the wood drying chamber (S5); checking a temperature by the temperature sensor, steam pressure by the pressure sensor, and water content by the balance (S6); exhausting the steam inside the wood drying chamber when the temperature, pressure, and water content are greater than a predetermined value (S7); circulating the steam in which the moisture is removed to an overheated steam generator (S8).;COPYRIGHT KIPO 2013;[Reference numerals] (S1) Laminating wood in a wood fixing jig; (S2) Inserting the wood fixing jig inside a chamber; (S3) Producing the saturated steam by a steam boiler; (S4) Producing the overheated steam; (S5) Drying the wood with the overheated steam; (S6) Checking and detecting temperature, pressure, and the percentage of water content; (S7) Automatically discharging steam; (S8) Circulating steam again after moisture is removed from the discharged steam
