I dried three red oak trees using a dehumidifier kiln. ( 4'x4'x16' 1" pink insulation foam box assembled with packing tape with a household dehumidifier and fan inside. Very low tech. Knock it down when not using it.)

The process is mostly: measure moisture content of wood, pick a humidity to maintain, check wood periodically to see if it is drying too fast or too slow. Weigh water coming out to monitor process.

Very low effort if you have space to allocate while in use. The wood came out well, no complaints.

One downside is you won't kill insects with heat, so you could have trouble if it is buggy wood.
