The research on drying characteristics and schedule of Catalpa ovata was conducted through a series of test with 100℃ -test method, The results show that： C. ovata is difficult to be dried, its main drying defects are the honeycomb and the cross section deformation. The grades of the initial check, the honeycomb, the cross section deformation, the twist deformation, the drying rate are 2, 4, 4, 2, 4 for C. ovata. Based on the grades of drying defects and corresponding drying condi...
