CENTRIFUGAL MACHINE

摘要

A screen bowl-type centrifugal machine that eliminates the problem of lowering of productivity caused by clogging by crystals at a screen portion, and in addition, where the amount of mesh leakage of processed objects at the screen portion can be reduced. Inside a hub (41) of a screw conveyor (40) is provided a cleaning liquid-receiving portion (43) for receiving a cleaning liquid for cleaning nozzles (45). Further, in the cleaning liquid-receiving portion (43) is provided a residual layer cleaning liquid-receiving portion (46) for receiving a cleaning liquid for cleaning a residual layer of processed objects at a screen portion (30). The residual layer cleaning liquid-receiving portion (46) is provided such that it is partitioned independently of the cleaning liquid-receiving portion (43). A cleaning liquid delivered to the residual layer-cleaning liquid-receiving portion (46) is directly jetted toward the residual layer of processed objects from the outer peripheral edge of a flight (42) with the residual layer-cleaning liquid-receiving portion (46) being partitioned from the cleaning liquid-receiving portion (43). The jetting is made by a cleaning route for a residual layer, which route is provided along a spiral direction of the flight (42).
