Abstract
Thin substrate plates are transferred in a horizontal or tilted posture on and by a substrate transfer means. Provided by a substrate transfer path is an air knife nozzle for scraping and drying off a liquid successively from surfaces of the substrates on the substrate transfer means. The air knife nozzle is located substantially at a uniform distance across a drying surface of a substrate plate on the transfer means. The air knife nozzle is provided with a slit-like nozzle hole to spurt jet air to the drying surface from an angular direction relative to a direction perpendicular to the substrate transfer direction and to sweep the substrate across the entire width of the drying surface and with a predetermined angle of incidence relative to the substrate transfer direction. Further, an air augmenting means is located in face to face relation with a corner portion of the substrate which is finally swept by the air knife nozzle, for increasing an amount of jet air to purge a liquid which is gathered in the comer portion as a result of the sweeping action of the air jet nozzle.
