Study shows benefits of longer reversing

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.
