STUDYING THE PARAMETERS OF TECHNOLOGY USED IN VACUUM DRYING PYINKADO (Xylia xylocarpa)

Abstract

The study is to evaluate the drying technology on the vacuum drying time for Pyinkado (Xylia xylocarpa). The results show that drying temperatures and cyclical timesat different levels varysubstantially. The experiments have identified the appropriate drying temperature and cyclical time to shorten the total drying time as follows: for the wood size 20x50x500 mm with a drying temperature 59^oC, and drying cyclical time 129 min, the total drying time is 42 hours, while with the same wood size the steam drying method needs 130 hours. For the wood size 50x50x500 mm with a drying temperature of 59^oC, and drying cyclical time119 min, the total drying time is 85 hours, while for the same size wood the steam-drying method needs 183 hours.
