Setting pitch, leave fans running?

[brdmkr]

The meter says my first load is dry.  I am ready to set pitch (SYP), but got to wondering... I know to turn the copressor off, but bo I leave the fans running?

  I don't think you would want to shut the fans off, if there is moisture it may cause problems with your fans. Additionally, the fans will help even out the heat and moisture through the kiln. I never shut my fans off.

Thanks Mark,

After I posted this, I began to wonder what I was thinking to even ask such.  Thanks much for verification.

How hot do you get it to set the pitch? Joe

My understanding is that you will "set" the pitch at whatever temp you use.  The key is in maintaining that temp for a period of time long enough to evaporate the volatile components of the sap.  The longer and hotter you bake it, the more firmly the pitch is set, and the wood won't bleed at temps lower than what you used.

For instance, Brdmkr is going to use his beams inside a house, so the 120° temps he used during drying should be sufficient to set the pitch for that purpose.  If his house gets hotter than that, a little bleeding will be the least of his worries!   The posts he is drying for his porch will be a different story.  The S. Ga. sun will get them hotter than that, so he will need to cook them pretty good.

I wonder what pine tastes like outta the oven. DanG?

Oh, gotta have a little fun, eh?

   I've been told 160 degrees for 24 hours. I not sure if this is by rule or what. I do know that the heavily pitched pine we saw needs to be at that temperature for the full 24 hours or we will have alot of problems with pitch build -up on our planer rollers and blades. Also, the sun shining through a window can heat up flooring, etc. to a temp. much higher than what you may think.
