Different aspects of terebinth drying in a microwave-rotary dryer were investigated including energy and exergy analysis, quality, and bioactive compounds. Experiments were performed using different parameters of microwave power (270, 450, and 630 W) and chamber rotation speed (5, 10, and 15 rpm). Drying time and effective moisture diffusivity were ranging from 43 to 137 min and 6.25 × 10−9 to 9.28 × 10−8 m2 s−1, respectively. Energy and energy efficiency increase with increasing microwave power and rotation speed. Exergy loss and improvement potential decreased with increasing microwave power and rotation speed. The physical parameters (shrinkage and total colour difference) increased with increasing microwave and rotation speed, while for the rehydration rate, an inverse relationship was observed. Also for bioactive compounds like total phenolics, total flavonoid content, and antiradical activity, a higher reduction was noticed with used higher microwave power and with higher rotation speed. Thus, the best parameters to obtain the highest content of bioactive compounds were microwave power of 270 W and rotation speed of 5 rpm. Comparison of different algorithms revealed that the grey wolf optimisation (GWO) algorithm had greater accuracy than the whale (WO) optimisation algorithm to predict all parameters of dried terebinth.

木犀的微波-旋转干燥工艺及质量参数优化

研究了微波旋转干燥器中 terebinth 干燥的不同方面,包括能量和火用分析、质量和生物活性化合物。使用不同的微波功率参数(270、450 和 630 W)和腔室转速(5、10 和 15 rpm)进行实验。干燥时间和有效水分扩散率范围为 43 至 137 分钟和 6.25 × 10 -9至 9.28 × 10 -8  m 2  s -1, 分别。能量和能量效率随着微波功率和旋转速度的增加而增加。随着微波功率和转速的增加,火用损失和改进潜力降低。物理参数(收缩率和总色差)随着微波和旋转速度的增加而增加,而对于再水化率,观察到相反的关系。同样对于生物活性化合物,如总酚类、总黄酮含量和抗自由基活性,随着使用更高的微波功率和更高的转速,观察到更高的降低。因此,获得最高生物活性化合物含量的最佳参数是 270 W 的微波功率和 5 rpm 的转速。
