<p>The plant is for driving out the steam from drying material (1) and has an energy unit for energy unit (3) for energy supply to the drying material, a gas mixt. of a carrier gas and steam circulated within the plant for contact with the drying material and an enclosure for the gas mix, the drying material and the energy unit. The enclosure comprises partly a tight connection (4) with a small cross-sectional surface for supply (41) of the drying process and mechanical support of solid material and partly a variable hose (5) as to its diffusion properties of a thin, flexible foil, (51) which between drying processes is drawn together bellows-fashion around and tied with its one hose end (52') to the connection. During drying it is drawn around the drying material and tied at its other hose end (52"). It is then filled with carrier gas (2) fed by a conduit (43). It also has an outlet (43) for condensate, pptd. on its inside.</p> |
