A vacuum dry kiln is disclosed, which controls moisture of a panel having various functions, processed by cutting a raw lumber is molded into charcoal, and more particularly, to a dry method for charcoal forming and a dry device therefor, in which a various shaped receptacles panels processed by cutting a raw lumber are put in a vacuum dry kiln and then processed into charcoal by exhausting moisture and poroligenous liquor contained in the raw lumber through a far-infrared heater without defect, and vacuum dry kilns are connected if necessary to enable vacuum dry of a long raw lumber. A charcoal production method in condition of vacuum drying comprising: shaping process for shaping material wood as rectangular or circularity with regular size and thickness by natural drying process and cutting, wherein the material wood has 25-39% moisten; vacuum drying process including providing the shaped material wood to the loading capacity21, keeping the inside temperature as 1050C ~ 1150C by hitting a far-infrared hitter25 and the loading capacity21 vacuum state by a vacuum pump33 of a vacuum inhalation device30, and inhaling moisture through a vacuum hole31 and pipe32 for 6 - 8 days until the moisture to be 5%. |
