An article treating device includes a belt conveyor having a belt that encircles a drive pulley at one end and an idler pulley at another end to support an article. At least one upper sprayer is positioned above the belt and is directed to spray a treatment liquid on an upper surface of the article on the belt. The article treating device sprays a second surface of article using a second sprayer by either: (i) spraying through perforations in a belt of the belt conveyor; and (ii) conveying the article over a flipping wedge to flip over the article before conveying under the second sprayer.
