Yield and dimensional quality of Samanea saman Jacq. Sawn timber at Guantanamo Agroforestry Enterprise sawmill
Abstract
The study was carried out in the San Justo sawmill belonging to the Guantanamo Agroforestry Enterprise from September 2018 to April 2019, with the objective of evaluating the yield and dimensional quality of the Samanea saman Jacq. sawn timber. The quality of the raw material was analyzed, and the yield and dimensional quality of the sawn timber was determined. A yield of 52.8 % was obtained, where the quality of the raw material, the diameters, length and conicity of the logs influenced. The logs are processed and assortments of 25 and 50 mm above the pre-established dimensions are obtained, although not enough to compensate for the volume losses due to the contraction and sawing variation that occur between and within the pieces, so the technical conditions of the machinery and the skill of the technical personnel must be taken into account.
