Abstract:
Method for the non-thermal drying of motor vehicle bodies, freshly painted with a water-based paint, in which the articles to be dried are introduced into a drier housing, the surfaces of the articles are subjected to dry air in the drier housing by forced convection and, after the paintwork has dried, the articles are discharged from the drier housing, after the air has passed through the drier housing the moisture-laden air being sucked away from the drier housing, the moisture contained being extracted from said air in an air drying device by condensation and the air thus being dried to a predetermined circulating-air target moisture and being blown into the drier housing again,wherein the drying performance of the air drying device (11) is adapted as required with a low degree of inertia to a changing infeed of moisture into the drier housing (1,1â€²), and wherein with the high condensation performance remaining unchanged, only a fraction of the circulated air which is adapted in size as required, is dried in the air drying device (11) to a residual moisture below the circulating-air target moisture, and the remaining untreated part of the circulated air is led back into the drier housing (1,1â€²) after being intermixed with the dried part-air stream.
