Higher energy demand for ventilating higher mass flux of hot air in fluidized bed drying (FBD) and SDG-7 of the UN has been actuated the researchers towards solar energy intervention in FBD. However, the thumb rules and systematic design calculation of the solar system for FBD have not been reported in the literature. In view of that, a novel solar thermal system was designed and developed by thermo-hydrodynamic analysis, considering the variable physical properties of bioproducts and fluctuating weather. The key design parameters were fresh and desired dried product's moisture content, physical properties of products, dryer capacity, desired drying temperature, ambient conditions, etc. In order to enhance the drying effectiveness, state-of-the-art technology for air dehumidification was integrated by using an aqueous blend of LiCl (35 %) + CaCl (5 %) desiccant. A solar photovoltaic system was also estimated for recirculating the moisture-saturated desiccant over an unglazed solar absorber to regenerate it. From the experiment of ginger drying, it was explicitly found that the developed solar FBD could supply sufficient heat energy (173.06–604.12 W/hr.) compared to the required heat load (124.65 W/hr.), which justifies the operational flexibility. The obtained solar heat fraction (∼1) and solar fraction (0.52–0.64) imply that the solar energy could fulfill the heat energy demand by 100 % and total energy demand (heat + electrical) up to 64 %. The energy efficiency, exergy efficiency, and sustainability index of the solar thermal system were obtained up to 48 %, 2.96 %, and 1.03, respectively. Aiming for effective energy utilization, an intermittent heat supply strategy was associated. Compared to continuous drying, intermittent drying reduced the active drying time (2–2.5 hrs.) and specific energy consumption (33.47–43.83 %) and fortified the dried ginger by reducing shrinkage (11–12 %) and increasing the rehydratability (up to 22.15 %).

在流化床干燥 (FBD) 和 SDG-7 中，对通风更高质量的热空气的更高能量需求已促使研究人员转向太阳能干预 FBD。然而，文献中尚未报道 FBD 的太阳系的拇指规则和系统设计计算。鉴于此，考虑到生物产品的可变物理特性和多变的天气，通过热流体动力学分析设计和开发了一种新型太阳能热系统。关键设计参数是新鲜和所需干燥产品的水分含量、产品的物理性能、干燥机容量、所需的干燥温度、环境条件等。为了提高干燥效率，通过使用 LiCl (35%) + CaCl (5%) 干燥剂的水性混合物，集成了最先进的空气除湿技术。还估计了一个太阳能光伏系统，用于在未上釉的太阳能吸收器上再循环湿气饱和的干燥剂以使其再生。从生姜干燥实验中明确发现，与所需的热负荷（124.65 W/hr.）相比，开发的太阳能 FBD 可以提供足够的热能（173.06-604.12 W/hr.），这证明了操作的灵活性。获得的太阳能热分数（~1）和太阳能分数（0.52-0.64）意味着太阳能可以满足100％的热能需求和高达64％的总能量需求（热+电）。太阳能热系统的能源效率、火用效率和可持续性指数分别达到 48 %、2.96 %、和 1.03，分别。为了有效利用能源，采用了间歇供热策略。与连续干燥相比，间歇干燥减少了主动干燥时间（2-2.5 小时）和单位能耗（33.47-43.83%），并通过减少收缩（11-12%）和提高再水合性（高达22.15%）。
