Measurement and Calculation of Moisture Content Distribution during Drying

摘要

The moisture distribution in wood during drying is important for the timberquality after drying. A great difference in moisture content between the center and the surface of a board could easily cause checks and deformation. A method to calculate moisture content distribution during drying has been developed and published earlier. The calculations are compared with a set of measurements of moisture content distribution during drying. The aim of this work is to compare their calculation method for moisture distribution during drying with measurements on ordinary sawn timber. The work is part of a research program on moisture distribution, tensions and deformations that occur during drying. The aim of the research program is to create a method to calculate drying schedules for industrial kilns that reduce quality loss.
