What it takes to dry WRC timber?

Dai | Announcement, Materials, Press release, Techniques

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.

Loading WRC, 13,000 bdft in one charge.

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.

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!
