Basrah Journal For Date Palm Research,
Volume 6, Issue 1, Pages 101-114
AbstractA 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
