Drying investigation of coriander seeds in a photovoltaic thermal collector with solar dryer.

This present work deals with experimental investigation of photovoltaic thermal collector design and development with solar dryer (PVTCSD). An solar experimental investigation is done on coriander seeds by natural, forced and open sun drying to estimate different parametric investigations such as solar radiation intensity, removal of moisture and the air outlet in the collector. Solar radiation is utilized as a source of energy to propel the photovoltaic thermal collector dryer; which was analysed in a drying testing chamber temperature in the range of 32°C to 59°C to dry 4 kg of coriander seeds. From the experimental study, it was understood that coriander seeds posses much more starting moisture 68% by weight and also the results proved that final moisture content has been decreased by 9% by weight during six bright days in the month of May 2021. The PVTCSD was used during the 9 a.m. to 4 p.m. In terms of understanding PVTCSD, solar sun drying with the forced convection achieved superior results than other two modes of operation.
