Abstract:
Equipment for drying bales of forage comprising:at least one unit for generating hot air equipped with a fan group that channels hot air onto at least one pair of treatment units stacked one over the other, each having a rectangular bottom chamber and a top chamber, kept apart by spacing devices having a rectangular bottom chamber and a top chamber, kept apart by spacing devices supporting the top chamber above the bottom chamber, and where one or more telescopic columns set between the bottom chamber and the top chamber transfer the hot air from the bottom chamber to the top chamber, said telescopic columns being operated by said spacing devices, said bales being set in each treatment unit between the bottom chamber and the top chamber stacked in two layers so that said bales can be dried by the countercurrent flow of hot air, wherein one or more of said telescopic columns is provided with shutoff dampers suited to opening/closing the air flow from the bottom treatment unit to the top treatment unit, wherein each of the two bottom chambers and top chambers is box shaped having a surface where one or more basically flat metal panels are removably connected and having holes shaped according to the shape of bale undergoing the drying treatment, and wherein said shutoff dampers selectively permit isolation of at least one of said treatment Units by opening/closing the air flow from one treatment unit to another treatment unit.
