The distance between the illuminated surface of the irradiation head and the surface of the production line is 60 millimeters, and it can sterilize materials below 40 millimeters. The bracket installation holes are spaced 50 millimeters apart to better adapt to the sterilization treatment of materials at different heights. The distance between the illuminated surface of the irradiation head and the surface of the production line is 360 millimeters, and it can sterilize materials below 330 millimeters. Customizable brackets can be used to accommodate materials in a larger height range. The shading adopts professional high-temperature resistance, thickened UV shading cloth, and ultra strong filtering of ultraviolet and visible light
