Abstract

Results of an experiment to enhance the drying rate of Bambusa nutans, Dendrocalamus membranaceus and Dendrocalamus strictus in round form are reported. It is seen that by peeling off a small portion of the outer skin, the drying rate of these bamboos can be enhanced without degrade. Results are suggestive of employing this technique by peeling off a larger portion of the outer skin albeit with caution to monitor the drying degrades due to such faster drying. It is seen that Dendrocalamus membranaceus dries fastest of the three bamboos studied as well as brings about the best results in faster drying by employing the peeling technique.

Abstract

Timbers produced in Indian forest are one of the useful resources for rural livelihood. Marketing of various products of timbers increases the economic status of rural people. Plasticization of wood is done to provide a desired shape in wood products. Wood bending is a necessary step in manufacturing of all agricultural and domestic products made from wood. In this study, experiment on wood bending has been done by using vapour phase ammonia treatment. Mango and poplar species are used for testing because these two species are largely found in northern and eastern India. From experiment, it can be concluded that poplar wood is more suitable for bending as compared to mango wood by vapour phase ammonia treatment. Moisture content in the wood has a role in vapour phase ammonia treatment of wood. The moisture content above FSP (Fibre Saturation Point) of mango as well as poplar wood is more suitable for bending the wood compared to moisture content below their FSP.
