摘要
通过对高温和常规温度干燥过程中木材温度及含水率变化与分布的测定,研究木材温度变化的特点和木材温度与含水率的变化关系。分析自由水蒸发面移动、水分状态改变对温度变化的影响。在此基础上,探讨利用木材温度控制干燥过程的可能性和实施方法,
In this paper, characteristics of wood temperature change and the relation between wood temperature and the moisture content were studied in the processes of higher and lower temperatures kiln drying. Movement of the evaporation front of free water and the changing effects of water condition to the temperature were analysed. According to the results obtained, the drying process could be controled by means of temperature changes, and the principle of applying this method should be further investigated.
