Mixing Species
Species with similar drying characteristics may be mixed in the same load with some level of
risk to the more difficult to dry species. Care should be taken to sample and control the kiln
operation based on the more difficult to dry species or the wetter species. As an example
Walnut from Green and Hard Maple from Green would not dry similarly enough to dry
together.
Mixing Thickness
Each layer between the plates must be the same thickness.
Frozen Lumber
Lumber that is frozen should be either thawed in warm storage prior to startup, or a warmup
stage should be performed in the process before vacuum is applied.
Drying Interruptions
Interruptions in the drying process from checking the wood, maintenance or any other
interruption causing the kiln to lose temperature and pressure for more than 2 hours will
exponentially increase the drying time and may cause drying degrade. Rapid case hardening
of the lumber during the interruption will slow the rate of diffusion of water to the surface of
the wood. This drying process must be restarted with more heat and energy to continue the
drying process.
