⚡ System Overview
The Box Type Solar Dryer is a compact and efficient system designed for drying agricultural produce, food products, and herbs using solar energy. It operates on the greenhouse effect, where solar radiation is trapped inside an insulated chamber to produce clean, uniform, and hygienic drying conditions.
Ideal for farmers, FPOs, SHGs, small industries, and rural entrepreneurs, this system ensures improved product quality, reduced drying time, and higher market value.
