Solar Seasoning of Timber in Bangladesh

M. A. Sattar
Director (Ex.)
Seasoning &Timber Physics Division, Bangladesh Forest Research Institute, Chittagong.

Abstract/ Executive Summary:

A greenhouse type solar kiln developed at the Bangladesh Forest Research Institute for seasoning timber has been extensively tested for the last ten years. Twenty-one such solar kilns have been installed by the private and public wood industries for commercial seasoning of timber. Timbers of different species for various end uses have been satisfactorily seasoned. The technique is found simple, inexpensive and effective throughout the year. Solar seasoning of timber thus offers an excellent prospect in Bangladesh.

Achievement/Findings:

Timber can be seasoned properly to the desired lower level of moisture content in suitably designed solar kilns. The greenhouse type solar kiln developed at the BFRI is found to be suitable for this purpose. The quality of the solar dried timber is superior to both conventional air and steam kiln dried timbers. Solar seasoning is found technically sound and economically attractive. This type of solar kiln can thus conveniently be used for seasoning timber in tropical locations like Bangladesh.
