Development of Hybrid Solar Dryer with PCM-Based Thermal Storage and PV-Assisted Airflow System for Efficient Agricultural Drying Ref.No.SSTCRC2658
1. Introduction
The proposed research focuses on improving agricultural drying systems by integrating solar energy with thermal energy storage using Phase Change Materials (PCM). Conventional open sun drying leads to significant post-harvest losses, poor product quality, and dependence on weather conditions. Existing solar dryers improve efficiency but are limited by intermittent solar availability.
This research aims to overcome these limitations by incorporating PCM for heat storage and a photovoltaic (PV) system to power airflow mechanisms. Several studies have demonstrated improved drying efficiency using PCM; however, there is still a need for optimized, low-cost, and scalable solutions suitable for rural applications. The proposed study contributes to this gap by designing an efficient, hybrid solar dryer suitable for continuous drying operations.
2. Research Progress
Initial literature review and conceptual design of the hybrid solar dryer system have been completed. Key components such as the drying chamber, PCM storage unit, and PV-powered airflow system have been identified.
Preliminary analysis indicates that PCM integration can improve drying duration and temperature stability. The next steps include fabrication of the prototype, experimental testing under different climatic conditions, and performance evaluation in terms of drying rate, efficiency, and product quality. Optimization of PCM material and airflow design will also be carried out.
