Abstract: The present invention relates to a solar-assisted grain dryer (1000). The solar-assisted grain dryer (1000) is disclosed, comprising a power source unit (100) and an air blower (200) configured to draw ambient air through an air inlet valve (701) and deliver controlled airflow via a variac (201). A parabolic trough collector (304) equipped with a solar tracking adjuster screw rim link (305) harnesses solar radiation to preheat the air. A plurality of air pre-heaters (300, 301), including a backup pre-heater (300), further elevate air temperature. A heat storage unit (11) having sub-units HSU (11A) and HSU (11B) stores excess thermal and recirculated waste heat and releases it during low solar conditions, each sub-unit incorporating concentric copper and PVC pipes (11A01–11A02; 11B01– 11B02), phase change material (11A05, 11B05), and control valves (11A0601–11A0625; 11B0601–11B0625). to be published FIG. 1
