Solar Powered Grapes Drying System Using Image Processing

Year: 2025

Type: article

Abstract: Conventional sun drying of grapes takes 7–12 days and suffers from contamination, uneven drying,and weather dependence. We present a smart, solar-powered drying system that uses a black acrylic tube tocollect heat, a Raspberry Pi 5 with a DHT22 sensor for real-time monitoring, and a machine learning modelto predict grape moisture. Heating (fan + IR lamp) is automatically switched off once grapes reach ~20%moisture, reducing drying time to 3–5 days. Remote monitoring via Blynk IoT and on-device display ensureuser convenience. Experimental trials show consistent quality, energy savings, and ease of operation.
