Abstract

Wet plasterboard to be dried is advanced along a path. At an upstream portion of the path, air is heated and directed towards the plasterboard for initial drying of the latter. A portion of the heated air is withdrawn and passed through one section of a heat exchanger whose other section contains water which exchanges heat with the heated air. The heated water is passed through a section of another heat exchanger whose other section contains fresh air which is heated by the heated water. The heated fresh air is directed towards the articles for further drying of the latter at a downstream portion of the path. A portion of the heated fresh air is exhausted and recirculated at the downstream path portion.
