The results indicated that the drying time of whole acorn was 442, 206 and 188 min at the air temperature of 65, 75 and 85&amp;amp;ordm;C, respectively. At the same temperatures, the drying time of kernel was 131, 56 and 76min. The results showed that the effect of drying air temperature increasing on the drying time reduction could not be significant on acorn drying at all conditions. The effective moisture diffusivity of whole acorn and kernel increased with increasing air temperature from 65 to 75&amp;amp;ordm;C. However more air temperature increasing, led to decreasing this property of acorn kernel. The critical temperature of acorn drying was about 75&amp;amp;deg;C in which acorn kernel had the highest effective moisture diffusivity. </abstract> <index>Open Science Index 66, 2012</index> </article>
