| Avacuum drying system is being designed and developed at National Institute ofVacuum Science & Technology (NINVAST) to dry various materials under vacuumconditions. Its performance and capabilities are tested by carrying outdifferent experiments on green (freshly cut) wood samples of Poplar andEucalyptus with dimensions of 990.6 mm x 76.2 mm x 25.4 mm and 469.9 mm x 50.8mm x 25.4 mm, respectively. These samples were dried from green moisturecontent (MC) 78% to 10% by this system at ultimate vacuum of about 1.6 x 103pascal and at a temperature ranging from 35oC to 55oC forabout 20 hrs. Drying quality tests included: prong test, warp measurement,surface checking and moisture content measurement, which were all performed.The resulting wood samples showed no dislocation and no excessive stressbuildup. If compared to ordinary drying process, the vacuum drying is rapid andthe drying rate increases with rise in temperature. The designed system isbeneficial for commercial use. |
