- Colour development on drying Roger B. Keey Agrociencias colour wood drying kiln brownstain The drying of wet materials induces a number of physico-chemical changes in the product, oftenreflected in colour. For dried products sold on appearance, like certain grades of wood, the extent ofcolour development is highly significant in terms of the materials end-use. Until recently, colour wasnormally assessed by eye, but the availability of convenient spectrophotometers has provided industrialusers with a means of quantitative description of colour. Examples from wood technology includeassessing the impact of biological surface treatment, the impact of ultraviolet radiation, and screeningof drying schedules by evaluating kiln brown-stain development. In other applications, the depth ofcolour might be used for the screening of drying schedules as an adjunct to other tests for stressdevelopment, or to pinpoint reaction and knotty wood in boards by an online scanner. 2005 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48570101 en http://www.redalyc.org/revista.oa?id=485 Maderas.
