What it takes to dry WRC timber?

  |   Uncategorized
Drying WRC in larger section than 4″ has been extremely challenge and we have
not found any services we could utilize to dry this wood. So we have decided
to purchase own and it took time to research and set to technology works
for us.
Drying wood can be done in a few different way but when it comes to leaving
wood essence in a wood, keeping maximum strength of wood fiber, it has to do
with temperature it uses, lower is better, we think it has to be below 70 degree Celsius
at the highest and we run under 60 degree Celsius.

On time monitoring the M/C in a kiln, total of 10 sensor is in actual wood and sensor runs system. Each drying process is driven by result base, once wood hit to programmed M/C, it kicks into next process. This is very unique that most system runs by time. monitoring the M/C in a kiln, total of 10 sensor is in actual wood and sensor runs system.  Each drying process is driven by result base, once wood hit to programmed M/C, it kicks into next process.

Green shows M/C coming down from 90%, red indicate temperature not going over 60 degree Celsius and blue is pressure in a chamber dropped to 10% of natural environment. Water will boil at 50 degree Celsius in this chamber.

This piece shows 12% at the core, WRC even shows different result along the length, and we are still R&D to overcome this to be dry more evenly.

This shows some timber still have wet spot, even wet spot exist along the timber some area are dry and some are wet, we will nail down the cause through the research!

 Best method I can think of is to shave with hand planer, wood fiber that has damaged by heat will not create thin shaving, and our wood does.

Shaving with fiber continuous for healthy drying.

 Ends are nice and shine after sanding, because it is dry also kept the natural oil that wood has!
