Revolutionizing Potato Drying: Performance Insights from Hybrid Solar Drying Systems

Abstract

This study investigates the performance of a hybrid solar dryer designed for the efficient drying of potato slices, aiming to address the challenges associated with conventional drying methods. The primary objectives were to evaluate the moisture removal rate (MRR) of the hybrid solar dryer and compare its effectiveness with traditional solar drying techniques. Through a series of experiments conducted from May to December 2024, the hybrid dryer demonstrated an impressive average MRR of 182.8 g/h, significantly outperforming both conventional (typically 150–180 g/h) and indirect solar dryers. The findings revealed that the hybrid system not only reduced drying time but also preserved the quality of the dried products, ensuring minimal nutrient loss. The MRR ranged from 158.4 g/h in December to 198.3 g/h in May, showcasing stable performance despite climatic fluctuations. Comparative analyses highlighted the superior efficiency of the hybrid design, making it a viable solution for food preservation, particularly in regions with ample sunlight. Additionally, the study emphasizes the importance of sustainable food processing technologies in enhancing food security and reducing agricultural waste. This research contributes valuable insights into the development of innovative drying solutions that can be effectively implemented in various agricultural settings, promoting better utilization of solar energy for food preservation. Future studies could explore further optimizations and integrations to enhance the performance of solar drying systems.
