Abstract
Poor preservation technologies are still a major challenge for the post-harvest losses of fruits and vegetables in
the tropical regions. This paper presents the design, fabrication, and performance evaluation of a low-cost photovoltaicassisted active indirect solar food dehydrator constructed mainly from locally available materials for sustainable food
preservation. The dehydrator consists of a flat-plate solar air collector, photovoltaic-powered forced convection, battery
energy storage, and an insulated drying chamber that provides controlled drying conditions independent of grid
electricity. The performance evaluation was conducted with tomato, banana, pepper, and apple for a loading capacity of
50, 100, 150, 200, and 250 g for 8 h drying period. The temperatures in the drying chamber rose from around 30–35°C to a
maximum of 58–64°C, which was significantly higher than the ambient temperatures (28–37°C) and consequently
enhanced moisture evaporation.
Solar drying offers a potentially accessible strategy for reducing post-harvest losses in regions with limited access to conventional energy and preservation infrastructure. This study developed a low-cost solar dryer from locally available materials and evaluated its thermal performance, drying kinetics, and effects...

Solar vapor generation is a promising technique for water purification, although the development of efficient and sustainable systems for practical use remains challenging. Here, we introduce a higher plant–derived evaporator, leveraging the structural advantages of plants and the synergistic integration of multiple co...
Solar hot-air drying technology has developed rapidly in the field of low-temperature fruit and vegetable processing; however, fluctuations in solar irradiance affect the stability of system energy supply and energy utilization efficiency. In this study, a cascaded photovoltaic/thermal (PV/T) solar drying system was co...

Although solar cabinet dryers (SCDs) represent an alternative to open sun drying (OSD) in the preservation of agricultural products, there are still challenges for SCDs such as the solar intermittency, unequal drying, and poor thermal efficiency. This systematic review brings together 30 peer‐reviewed studies from...

Water-evaporation-induced energy harvesting has emerged as a promising blue energy technology; however, widespread application is hindered by water-saturation-induced instability and limited functionality. Herein, a low-cost flexible Janus water-evaporation-induced generator (WIG) is fabricated via facile immersion a...
