This study aimed to enhance the efficiency of banana drying processes through the development and testing of a phase change heat storage system utilizing heat from charcoal briquettes.The system was designed and modeled using SolidWorks software, incorporating a parabolic dome and a heat storage unit made of SS400 steel.Temperature measurements were conducted within the dome and the heat storage system and efficiency testing was performed by comparing drying methods.Moisture content testing of market-dried bananas provided baseline data, with an average moisture content of 26.51% (w.b.).Drying experiments using a parabolic dome solar dryer demonstrated a reduction in banana moisture content from 70.18 to 25.53% (w.b.) after 4 days.Subsequently, testing with the phase change heat storage system revealed a further reduction in moisture content to 25.58% (w.b.) within 3 days of drying.The systemmaintained temperatures inside the dome during nighttime, utilizing heat from charcoal briquettes to sustain drying processes.The results indicate that the phase change heat storage system significantly improves drying efficiency, with a 25% increase in production capacity compared to traditional solar drying methods.Implementation of this system offers a sustainable solution for banana processing, contributing to increased efficiency, reduced energy consumption, and enhanced product quality.This study underscores the potential of innovative drying technologies to address challenges in agricultural processing and promote sustainability within the industry.
