A rust preventive is mixed in the washing liquid of No. 0. The pallet P that has been degreased and rinsed is transferred from the lifting plate 54 to the conveyor 4 shown in FIG. 2C, and is carried into the draining station 18 shown in FIG. After the drop of the washing liquid is cut off at the draining station 18, the pallet P is carried into the drying station 14. In the drying station 14, the plate-shaped components S are heated by a panel heater so that the water is blown to some extent so that the plate-shaped components S are easily separated from each other by air blowing in the next hot-air blow station 10.

The plate-shaped component S thus preliminarily dried
Is carried into the hot air blow station 10 together with the pallet P. In the hot air blow unit 12 in the hot air blow station 10, as shown in FIG. 6, the air blow nozzles 94A and 94B move in parallel while blowing hot air along the holding shaft 74 of the loaded pallet P. Thereby, the holding shaft 74
A large number of plate-shaped components S penetrated through are dried sufficiently by hot air while being cut off one by one by air pressure. Subsequently, the pallet P is carried into the cool air blow station 6, and the cool air blow unit 8 is similarly cooled by the air blow nozzle. After the degreasing, rinsing, drying, hot-air drying, and cooling are performed as described above, the pallet P holding the plate-like components is carried out from the carry-out port 2 shown in the upper part of FIG.
