In prior blog articles, we have discussed the motivations behind lumber drying and explained conventional approaches. Batch kilns – the time-tested solution – remain integral in turning moist wood into dry lumber. There are ongoing endeavors that are directed towards advancing alternative technologies in recent years with the aim of achieving faster drying time, improved quality, as well as enhanced sustainability. In this blog, we are excited to delve into three additional state-of-the-art drying solutions, discovering the opportunities these modern technologies may bring to the world of lumber processing.

Digital transformation is the integration of digital technologies to enhance productivity, efficiency and decision making in all areas and sectors. The industrial sector is currently joining the wave and undergoing a true revolution towards a digitalized sector at a slow but consistent pace.

Wood is a hygroscopic material, meaning it exchanges water with the surrounding air, absorbing or desorbing it. This exchange is regulated by the air’s hygrometric conditions, such as temperature, relative humidity and atmospheric pressure. So, for a given climate, there’s a balance where wood is neither absorbing nor desorbing.

Why do we need to dry lumber? Working in the wood processing industry and, more specifically, in the lumber drying sector, you get immersed in a lot of technical concepts when monitoring the lumber drying process.

Why is this process so complex? In this post, we will break it down into three categories: variability in nature, quality control/compliance, and optimization
