Demand for all resources, especially food, water, and energy, has increased with the rapid increase in the world population. These resources are limited and not enough for the growing population of the world. Therefore, the food-energy-water nexus approach has gained much attention in recent years. Less energy and water consumption and less waste generation became the target for the more sustainable food production. Qualitative and quantitative losses in agricultural commodities growing in rural areas depend both on the structure of foods and incorrect or inadequate process applied to postharvest operations to preserve food. Therefore, drying is the most preferred food preservation method. To minimize the energy consumption during drying process, renewable energy technologies are emerging as an alternative solution. It reduces dependency of fossil fuels, adds value to agricultural products to meet the increasing demand, and minimizes qualitative and quantitative losses. In this work, theoretical and experimental studies of photovoltaic-thermal (PV/T) or photovoltaic (PV) integrated food-drying systems were comprehensively reviewed. The researches covered in this review are classified into three groups: PV module integrated, PV/T collector-assisted food-drying systems, and PV/T-assisted heat pump-drying systems.
随着世界人口的快速增长，对所有资源，尤其是食物、水和能源的需求也在增加。这些资源是有限的，无法满足不断增长的世界人口的需求。因此，近年来食物 - 能源 - 水关联方法受到了广泛关注。减少能源和水的消耗以及减少废物产生成为更可持续粮食生产的目标。农村地区种植的农产品在质量和数量上的损失既取决于食品结构，也取决于收获后用于保存食物的操作过程不正确或不充分。因此，干燥是最常用的食品保存方法。为了使干燥过程中的能源消耗最小化，可再生能源技术正在成为一种替代解决方案。它减少了对化石燃料的依赖，增加了农产品的价值以满足不断增长的需求，并最大限度地减少了质量和数量上的损失。在这项工作中，对光伏 - 热（PV/T）或光伏（PV）集成食品干燥系统的理论和实验研究进行了全面综述。本综述涵盖的研究分为三组：光伏模块集成、PV/T 集热器辅助食品干燥系统和 PV/T 辅助热泵干燥系统。
