Abstract

The quality of agricultural products is frequently compromised by energy-intensive drying methods, highlighting the need to develop more efficient drying techniques. Infrared drying has surfaced as a compelling approach for enhancing energy efficiency and product quality. This study examines the thermal characteristics, physicochemical properties, and drying kinetics of garlic slices subjected to different infrared radiation intensities (0.1–0.3 W/cm2), air temperatures (35–55 °C), and airflow rates (0.5–2 m/s). An artificial neural network (ANN) with 99 % predicting accuracy was employed to refine drying parameters, aiming to improve drying efficiency and minimize specific energy consumption (SEC). The findings demonstrate that elevated air temperature and infrared intensity significantly decreased drying time, with the minimum duration of 290 min recorded at 55 °C, 0.3 W/cm2, and 0.5 m/s airflow. The SEC was reduced to 3.78 MJ/kg under these optimal conditions. The increase in infrared radiation and temperatures resulted in a decrease in allicin content, dropping from 17 % to 11.53 %, as well as a reduction in vitamin C retention, which fell from 0.112 mg/g to 0.05 mg/g. Nonetheless, there was an enhancement in thermal efficiency, achieving a peak of 51.9 % at 55 °C and 0.1 W/cm2. The ANN model exhibited impressive predictive accuracy in estimating drying time, SEC, and thermal efficiency. The results offer significant insights for enhancing infrared drying technology, presenting a sustainable method to decrease energy usage while maintaining key quality characteristics of dried garlic.
红外干燥机性能评估的计算智能和机器学习方法:质量分析、干燥动力学和热性能
农产品的质量经常受到能源密集型干燥方法的影响,这突出表明需要开发更有效的干燥技术。红外干燥已成为提高能源效率和产品质量的一种引人注目的方法。本研究考察了不同红外辐射强度(0.1-0.3 W/cm2)、空气温度(35-55℃)和气流速率(0.5-2 m/s)下大蒜片的热特性、理化性质和干燥动力学。采用预测精度达99%的人工神经网络(ANN)对干燥参数进行细化,以提高干燥效率和降低比能量消耗(SEC)。研究结果表明,升高的空气温度和红外强度显著缩短了干燥时间,在55℃、0.3 W/cm2、0.5 m/s气流条件下,干燥时间最短为290 min。在这些最佳条件下,SEC降至3.78 MJ/kg。随着红外辐射和温度的增加,大蒜素含量从17%下降到11.53%,维生素C保留率从0.112 mg/g下降到0.05 mg/g。尽管如此,热效率有所提高,在55°C和0.1 W/cm2时达到51.9%的峰值。人工神经网络模型在估计干燥时间,SEC和热效率方面表现出令人印象深刻的预测准确性。研究结果为改进红外干燥技术提供了重要的见解,提出了一种可持续的方法,在保持干蒜的关键品质特征的同时减少能源消耗。

期刊介绍: The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
