马蹄豆锯材干燥工艺试验研究

以22 mm厚马蹄豆锯材为研究对象,采用百度试验法对马蹄豆锯材进行干燥特性研究,并制定初步干燥基准,采用低温除湿干燥窑对马蹄豆锯材进行干燥工艺优化试验.结果表明,在保证干燥质量前提下,22 mm厚马蹄豆锯材干燥前期适宜低温干燥,含水率下降速度控制在0.14％/h;干燥中期含水率下降速度控制在0.11％/h;干燥后期含水...

Study on Drying Technology of Martiodendron Parviflorum Thick Timber

The wood drying process on Martiodendron parviflorum thick timber of 22 mm was explored.The characteristics of Martiodendron parviflorum timber by Baidu test method were studied,and drying process optimization of Martiodendron parviflorum timber by using low temperature dehumidification drying kiln were tested.The results indicated that the 22 mm Martiodendron parviflorum thick timber suitable for dehumidify of low tepid pump,and the water decreases rate was controlled at 0.14%/h in the early stage of the wood drying.The rate of decrease of moisture content in drying medium was controlled at 0.11%/h,and in the late drying period was controlled at 0.08%/h.The drying period was 14 days,and the dried lumber achieved second level requirement in accordance with GB/T6491-2012 by used optimization drying schedules.
