In past years, our lumber was exclusively air dried under cover of our hoop tents. With the sun’s heat and fans to circulate the air, it has sped up the drying process versus just being stored in a damp container. Yet we knew we could improve both the speed and quality with the addition of a vacuum kiln.
Our kiln differs from solar kilns by drying the lumber at a lower temperature. The material is loaded in a chamber which circulates hot air to dry the wood under vacuum pressure. Water is forced from the center of the wood and is circulated as water vapor throughout the chamber to condition the material, preventing cracking or case hardening. As a plus, the wood retains more of the original color while gaining stability.
Our process produces high quality lumber with minimal degrade significantly faster than conventional methods.
