This study presents a mathematical modeling of the drying curve of raw cork planks in a cork pile in the ﬁeld, under natural sun drying conditions. Experimental data were obtained by following the water loss (i.e. by daily weighing) of 97 cork planks positioned in nine points within a cork pile. Immediately after harvesting, the raw cork planks had a mean moisture content in a dry basis of 40.4% and after 20-day drying 16.6%. The drying process of the cork planks showed three phases: drying was very fast in the ﬁrst 2 days; in the next 2–15 days there was a decreasing drying rate; and a ﬁnal phase, after 15 days in the cork pile, with a slightly decreasing drying rate. Mathematical modeling provided a direct relation between moisture content and drying time. After comparing sixteen empirical drying models, the Modiﬁed Henderson and Pabis model showed the best ﬁt. According to this model, the cork planks are commercial dry (14% moisture content in a wet basis) 15 days after harvest.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Institution of Chemical Engineers</style></notes></record></records></xml>
