| Abstract | ||
| Corn was dried in an indirect locally manufactured solar dryer with natural flow . It consists of solar collector of 0.5 m2 area and 25 kg capacity drying chamber, those of which was made of wood. The results compared with those of natural sun drying in January 2007, and showed that corn could be dried by using solar energy in Basrah city. Moisture content, water activity and specific heat were reduced with increasing day hours, The average and this reduction of drying time was higher in solar dryer than using natural sun drying method and the decreasing were 45%,19.5%,45%,19.49%,26.71,13.5 respectively . The average temperature in the drying chamber was 41.85 oC and the weather temperature was 18 oC. Experimental equations were proposed to calculate corn specific heat and moisture content as well as temperature of solar drying chamber at given solar radiation intensity and weather temperature.The differences between solar dryer and natural sun drying were not significant in the heat conduction. | ||
