| 摘要 |
The apparatus (1; 1A', 1B', 1C) for drying cylindrical (3) and/or parallelepiped bales of moist forage comprises an assemblage (2) of horizontally extending balanced isobaric ventilation chambers (2a, 2b, 2c) in overlying relationship. The lower ventilation chamber (2a) presents a plurality of blowing apertures (4; 11) on its upper face and is able to withstand the weight of the bales (3) positioned directly on it in correspondence with the relative blowing apertures (4; 11). The upper ventilation chamber (2b) presents a corresponding plurality of blowing apertures (4; 11) on its lower face, whereas the intermediate ventilation chambers (2c) present a corresponding plurality of blowing apertures (4; 11) both on their upper face and on their lower face and are able to withstand the weight of the bales (3) positioned directly on them in correspondence with the relative upper blowing apertures (4; 11). Means (6) are provided for mutually moving the ventilation chambers (2a, 2b, 2c) vertically in the two directions.
