<正>对红松、白松、马尾松等厚度为20—55毫米的板材进行了电热远红外干燥试验,干燥质量多数良好。窑内采用了强制通风设施,改善了干燥均匀度。 试验发现,在这一干燥技术中起主导作用的仍是介质的对流传热,而不是红外辐射,辐射能的利用大约不超过5％。如何正确评价和运用远红外干燥技术,是值得讨论的。

Experiments on drying the lumber of Firms Khorajensis Sieb. et Zucc. and P. massoniana Lamb, of 20-55 mm thickness by using far-infrared rays were made. Forced draught equipment was employed in the kiln to improve the evenness in drying. Results proved to be satisfactory.It was found in practice that it is the heat convection of mediums, not the infrared radiation, that plays the predominant part in the drying process. Through a simple test, the mechanism of wood drying has been found out. The test also showed that the percentage of the radiation energy used was less than 5. This will surely be very useful in the correct understanding and application of the technique of far-infrared drying.
