Beschreibung
Zusammenfassung:	The invention belongs to a drying method of resin impregnated modified wood. The method comprises the five stages of preheating, conventional drying, high-frequency drying, high-temperature solidification and balancing and humidifying. The method comprises the steps that firstly, the resin impregnated modified wood is stacked and loaded into a dry kiln, preheating is performed under the conditionof a temperature slightly higher than the conventional drying initial temperature, steam injection is started intermittently, and higher relative humidity of the interior of the kiln is kept; secondly, steam injection is stopped, a fan is started, conventional drying is started, and the temperature is controlled to be within the range of 40-80 DEG C; thirdly, under the temperature condition of 80-100 DEG C, a high-frequency generator is started, the frequency is controlled to be within the range of 5-20 MHz, and high-frequency drying is performed on the modified wood; and the temperature inside the kiln is controlled
