One hour's fan rotation reversal has long been the standard in modern batch kilns. All the same, there have been few proper studies into how lumber is affected by fan reversal time. Because changing fan rotation parameters in the control system is easy, Valutec, Luleå University of Technology and RISE wanted to conduct a study within the Bioinnovation project into whether a longer reversing time can help improve the drying process.

Many of us will soon be taking a short break for the Christmas and new year holidays before a new business year begins. Even though 2020 hardly turned out the way we all expected, Valutec can think of three reasons why we should look forward to 2021. We're talking smarter processes, the sustainability benefits of wood, and faith in the future.
