| Abstract: | The technology of solar steamy hot-air drying uses the vacuum tube collector to heat water and produce steam,then converted it into hot air through the heat exchanger.The purpose is to realize the drying of agricultural products.This paper develops a set of test device.The experiments of drying carrots were carried out to test the drying system＇s performance.The results show that when solar power reaches above 750W/m2,the steam can stable work for about 5～7 hours;The temperature of the dryer＇s high temperature section can be stabilized at around 55℃,and the temperature of the low can be stabilized at around 40℃.The drying effect of carrots is good. |
