The utility model discloses a solar preserved fruit drying room, comprising an insulating wall body 1, and an arc polycarbonate sheet roof 2. The solar preserved fruit drying room is characterized in that a convex humidity discharge groove 4 is arranged in the middle of the arc polycarbonate sheet roof; humidity discharge adjusting windows 7 are arranged at two sides of the humidity discharge groove 4; a humidity discharge groove polycarbonate sheet 3 is arranged at the top of the humidity discharge groove 4; the arc polycarbonate sheet roof 2 and the humidity discharge groove polycarbonate sheet 3 are fabricated by a hollow polycarbonate sheet 6 and coated with ultraviolet-proof coatings 5; and air inlet adjusting windows 8 are arranged at two sides of the insulating wall body 1. By using the solar preserved fruit drying room, the preserved fruit is dried in a sealed space; pollution of foreign matters such as dust is prevented; the solar energy is utilized to dry; and the drying cost is reduced. The arc polycarbonate sheet roof 2 and the humidity discharge groove polycarbonate sheet 3 are made of the hollow polycarbonate sheet 6 and coated with the ultraviolet-proof coatings 5. Therefore, the effect of an ultraviolet ray is reduced; and 2, direct injection of sunlight is avoided, so that the preserved fruit product keeps good color and luster.
