| contents | The influence of some factors on the timber drying process, analyzed by a global simulation model Jarl-Gunnar Salin Agrociencias simulation wood drying A model for the simulation of timber drying in a batch kiln has been used for the investigation of aset of different questions related to this drying process. The model is global in the sense that it takesinto account that the drying air local climate changes as it passes through the kiln load. In Scandinavian,practice kiln stacks are normally built from boards of random lengths so that every second board islocated flash at one end of the stack and the other boards flash at the other end. This kiln stack geometryis also included, as well as airflow reversal.This model has been utilized to investigate the following situations:The effect of sticker thickness on airflow, drying time and final MC standard deviation is illustrated.Thicker stickers mean less timber in a given kiln, but results in shorter drying time. The kiln dryingcapacity is not influenced very much, but the final MC spread is decreased.The influence of kiln parameters on the final MC standard deviation is investigated and simpleformulas are presented for the estimation of this variation. 2005 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48507305 en http://www.redalyc.org/revista.oa?id=485 Maderas.
