Project Overview

Designed and developed a solar dryer assembly in SolidWorks, optimizing airflow and thermal dissipation through forced convection channels and strategic DC fan placement. The project resulted in significant energy efficiency improvements and practical agricultural applications.

The Challenge

Traditional solar drying methods were inefficient and weather-dependent. The challenge was to create a low-cost, efficient solar dryer that could reduce moisture content in agricultural products while being accessible to small-scale farmers and providing real-time monitoring capabilities.

Our Solution

Designed a solar dryer with optimized airflow using forced convection channels and strategic DC fan placement. Fabricated a low-cost system using ASAWA insulation panels. Developed a LabVIEW-based voltage monitoring system using NI USB DAQ 6001 and Hall-effect sensors for real-time diagnostics and data logging.
