EXPERIMENTS ON A NEW SMALL-SCALE SOLAR DRYER

A new solar dryer, which consisted of a solar air heater and a drying chamber, was developed for drying food products. The present drying sy stem was successfully tested using sultana grapes, green beans, sweet peppers and chilli peppers. The traditional sun-drying experiments wer e employed and compared with the solar-drying experiments. It was show n that the use of this type of solar dryer reduced the drying time sig nificantly and essentially provided better product quality.
