Abstract

This research article evaluates the performance of an Inverted Solar Collector (ISC) dryer for drying Sandfish in the Sahara region of Algeria (El-Oued City). Experimental studies compared an ISC dryer equipped with copper fins (CF) and paraffin wax (PCM) latent heat storage to an ISC dryer without CF-PCM, as well as to natural sun drying. Performance assessment considered both thermal efficiency and product quality. Sandfish with an initial moisture content of 73.18% were dried to a final moisture content of 11.34% (wet basis) in 43 h using the ISC dryer with CF-PCM, in 55 h using the ISC dryer without CF-PCM and over 100 h with natural sun drying. Results demonstrate a reduction in drying time of 27.90% compared to the ISC dryer without CF-PCM and up to 100% compared to natural sun drying. Additionally, solar drying enhanced the water, ash, protein, and lipid content of the dried Sandfish. Experimental findings revealed that the dried Sandfish contained 55.7% protein and 13.4% lipids, compared to 19.6 and 2.8%, respectively, in fresh Sandfish. From a nutritional quality perspective, the ISC dryer with CF-PCM proved to be the most effective method for Sandfish preserving.

利用翅片与蓄热相结合的新型干燥机对沙鱼进行太阳能干燥：在阿尔及利亚撒哈拉沙漠的实验研究

本研究文章评估了倒置太阳能集热器（ISC）干燥机在阿尔及利亚撒哈拉地区（El-Oued市）干燥沙鱼的性能。实验研究比较了配备铜翅片（CF）和石蜡（PCM）潜热储存的ISC干燥器与不配备CF-PCM潜热储存的ISC干燥器以及自然日光干燥器。性能评估考虑了热效率和产品质量。将初始含水率为73.18%的沙鱼用带CF-PCM的ISC干燥机干燥43 h，用不带CF-PCM的ISC干燥机干燥55 h，用自然阳光干燥100 h，最终含水率为11.34%（湿基）。结果表明，与没有CF-PCM的ISC干燥器相比，干燥时间减少了27.90%，与自然阳光干燥相比，干燥时间减少了100%。此外，太阳能干燥提高了干燥沙鱼的水分、灰分、蛋白质和脂质含量。实验结果表明，干沙鱼的蛋白质含量为55.7%，脂肪含量为13.4%，而鲜沙鱼的蛋白质含量分别为19.6%和2.8%。从营养质量的角度来看，采用CF-PCM的ISC干燥机是保存沙鱼最有效的方法。
