ABSTRACT:
Plate-like workpieces such as thin ceramic plates which are ultrasonically cleaned are housed in a tray having an air-permeable bottom plate and a plurality of air-impermeable sidewall plates extending from peripheral edges of the bottom plate. To dry the cleaned workpieces, the tray is placed in a drying tank and supported on a support base on the bottom of the drying tank at an inclined attitude. The drying tank is combined with a hot-air duct which is detachably coupled to respective edges of the sidewall plates of the tray when the tray is supported on the support base. The hot-air duct supplies hot air into an interior space of the tray which is surrounded by the sidewall plates. A suction duct is coupled to the bottom plate of the tray supported on the support base and draws hot air supplied from the hot-air duct from within the interior space through the bottom plate.
