Title: Drying thick pine question/dh4000
Post by: Lance in Ontario on December 13, 2008, 05:19:49 AM
I put about 2200 bdft of 9/4  white pine in my dh4000 about 2 weeks ago.It was reading around 20% mc when I first started. The kiln is reading 120f and 0% rh but the pine is still reading 14-16% mc after 2 weeks. Looks like there is no more moisture coming out of the boards.Shouldnt the rh in the kiln be higher until the moisture content of the board gets closer to 8% ?Should I turn the heat up some more?Or is this normal? My first time for thick pine.

Puzzled here how you can get 0% rh...?  How do you measure it?

And how are you measuring mc of the wood?

That is what the kiln controller is reading,last time I checked before it was reading zero it was around 10-12 rh.I am checking the load with a moisture meter

I would do an oven dry test to check your meter reading.

Make sure you are properly correcting the moisture content reading for temperature and species. What kind of meter are you using?
