A hybrid convective‐infrared‐rotary drum (CIRD) dryer was designed and fabricated to examine the drying behavior of the green pea under different experimental conditions. In this study, the effect of temperature was evaluated at three levels (40, 55, and 70°C); while the infrared (IR) power and drum rotation speed were also varied in three levels: 250, 500, and 750 W and 5, 10, and 15 rpm, respectively. The effect of these three variables was assessed on the drying, durability extension and quality of the green peas. Drying of green pea with CIRD method by the following conditions: air temperature, IR power and drum rotation speed enhanced the drying rate, the variations in the effective moisture diffusion coefficient, rehydration ratio, total phenol content, and antioxidant capacity. In addition, increasing temperature, IR power, and rotary speed reduce the color changes and specific energy consumption. The highest effective moisture diffusion coefficient, rehydration ratio, total phenol content, and antioxidant capacity were 1.58 × 10−11 m2/s, 2.19 ± 0.13, 12.99 ± 0.35 mg GAE/g dry sample, and 75.73 ± 0.82%, respectively. Moreover, the lowest specific energy consumption, color variation, and pH were 107.49 ± 0.88 MJ/kg, 44.40 ± 0.51, and 4.98 ± 0.11, respectively. The highest qualitative and nutritional preservation belonged to the highest air temperature, maximum IR power, and highest drum speed.

混合(对流-红外-转鼓)干燥对豌豆品质属性的影响

设计并制造了混合对流-红外-旋转鼓式干燥机(CIRD),以检查豌豆在不同实验条件下的干燥行为。在这项研究中,在三个水平(40、55和70°C)下评估了温度的影响。而红外(IR)功率和感光鼓转速也分别在三个级别上变化:250 W,500 W和750 W和5、10和15 rpm。评估了这三个变量对豌豆的干燥,耐久性延伸和品质的影响。通过CIRD方法在以下条件下干燥豌豆:空气温度,红外功率和滚筒转速提高了干燥速率,有效水分扩散系数,水合比,总酚含量和抗氧化能力的变化。此外,温度,红外线功率增加 转速降低了颜色变化和单位能耗。最高有效水分扩散系数,复水率,总酚含量和抗氧化能力为1.58×10-11 m 2 /s、2.19±0.13、12.99±0.35 mg GAE / g干样品和75.73±0.82%。此外,最低的单位能耗,颜色变化和pH分别为107.49±0.88 MJ / kg,44.40±0.51和4.98±0.11。最高的定性和营养保存属于最高的气温,最高的IR功率和最高的滚筒速度。
