PURPOSE:To obtain the residual removing device which is easy to maintain by removing waterdrops attached to an injecting nozzle without fail by blowing air, without degrading removal performance even though the device is used for a long period. CONSTITUTION:A swing plate 49 constituting a moving means 26 is lifted after washing, and a sucking nozzle 29 is lifted from washing liquid in a washing tank 22. Under this state air in a water discharge tank 23 is sucked, air is blown from a nozzle 37, and air is sucked by the sucking nozzle 29. Said drying process is carried out for several tens of seconds. After said drying, a few waterdrops are remained around the tip of a nozzle 30. An air valve 45 is pulsatingly opened for removing the residual waterdrops, air is blown from the air blowing nozzle 37 to the tip of the nozzle in the direction perpendicular to the nozzle 30. In this constitution, the drying is performed in a short time without fail, and the performance can be maintained even though the operation is repeated many times. |
