Abstract: The present invention relates to a method for drying hollow timber which comprises the following steps: molding hollow holes on a large section of a timber; and drying the large section timber with the hollow holes using hot air. The method additionally includes a step of providing a moisture separation preventing unit on the outer surface of the large section timber with the hollow holes. By applying the moisture separation preventing unit, the evaporation of the moisture from the outer surface is controlled, and the moisture is evaporated inside the hollow holes to prevent the generation of cleaving which is a defect generated from drying and improving the drying speed.

Abstract: PURPOSE: A hollow wood drying method is provided to accelerate a drying operation based on high temperatures by sealing the external side of wood with a hollow structure and suppressing the escaping of moisture through the external surface of wood. CONSTITUTION: A hollow part is shaped in wood of large sized cross sections. The wood with the hollow part is dried based on heating. A moisture escaping preventive unit is arranged on the external surface of the wood. The moisture escaping preventive unit is arranged on the surface or the transversal cross section of the wood. The moisture escaping preventive unit is physical or chemical. The physical moisture escaping preventive unit is cloth, synthetic resin wrap, aluminum wrap, iron, or paper, and the chemical moisture escaping preventive unit is a film forming agent.
