Wf Drying schedules
« on: February 16, 2012, 12:38:41 PM »
Anyone have any ideas on running a wider depression on WF?? Right now I am at 195/140 at the end of my schedules. I am wondering if I drop the wet bulb even further, if it will decrease my drying time much?

My guess is that going from a 55F depression to something greater will not impact the drying time a lot.

If you are in the inland empire region, the fir might be easier to dry, but for the coastal white fir if your final target MC is around 15%, that is a very large depression.  Seems like it would contribute toward overdry and MC variability.  I'd be inclined to have a big depression in the middle (like 40F) and make it smaller at the end (like 25-30).

A little higher wet-bulb may make the kiln a little more energy efficient too.
