Small Batch Lumber Drying

Wood drying is one of the most important steps in processing hardwood lumber. The drying process removes more than one-third of the weight of a fresh-sawn board.
Doing this increases wood strength and makes it more dimensionally stable and less subject to mold and decay. Most carpenters, cabinetmakers, and furniture makers won't consider a wood purchase until it has undergone a drying process appropriate for their intended use.

I like the section that describes the different methods of drying their limitations. This is a benefit to those starting out thinking about getting into wood drying.

When it mentions "The greatest concern with drying hardwoods is removing free water from the entire thickness before removing bound water from the surface to minimize shrinkage and stress.", it requires the impossible. The fundamentals of mass transfer includes a moisture gradient. Thereby the the loss of bound water before the free water is removed from the core.
Also it does not mention the need to be aware of the development of drying stresses, which can not be avoided in the drying process.
