I've did many tests for drying Gmelina sp wood species. They have moisture content between 65-70%.
Much of journal or scientific log start the schedule from 45-50oC with EMC on 20%.
But, when I use that schedule, it makes the wood crack and casehardening (which outside become drier than inside wood). And actually, the outer side MC's 6-26%, and inside still 50-60%.
Is there any possible drying schedule for Gmelina and prevent drying defect from the wood itself? Thank you
