| Abstract | ||
| A semi mixed solar dryer for date drying was designed , manufactured and tested Its consist of a plastic and glass cover , matel .absorber wire , ban , their color is a black and non brightness , chimney and small pipe solar collector . A semi mixed solar dryer was fixed on the iron body. The result showed that the mean of available solar radiation energy in Basrah city in September was 764.30 W/m2 , and mean of temperature in the solar dryer arrived to 72 oC . The moisture content for date was reduced with increasing drying time , the reducing with usage of solar dryer was higher than the natural sun drying . Drying date by solar dryer wasn’t moisture absorber from weather compared with the natural sun drying, Daily drying efficiency was reduced with increasing of drying time , while its for the solar dryer was higher than the natural sun drying. | ||
