How do medium large companies dry large slabs?
« on: July 11, 2018, 10:36:02 PM »
Hey everyone! Finally signed up after following the forums for about two years intermittently. Im starting to chainsaw mill and dry to learn and eventually sell my wood at appropriate pricing. Lots of good threads on realizing the true cost of production at small scale. 
My question for starting this thread is strictly out of curiousity. How do companies like Berkshire Products ( dry slabs that are over 50 inches wide and 4+ think with minimal cracks/checking. What sort of drying protocol might they use? A mix of air dry/vacuum or DH kiln? Large batches or multiple small kilns? What do you guys think?

If they are drying 4 inch thick material with no cracks I would bet they are using a vacuum kiln

Not sure on the terminology, but a lot of mills with large budgets are using high frequency radio kilns, if I am saying that right. I have seen videos/pics of green slabs going into those kilns and being bone dry in just a few days with no checking,
