The sorting system ejection

The operational lifetime of the ejectors must be in the region of at least a billion or more cycles. Food processing is usually a 24-hom-a-day, all-year-round operation. Operators cannot afford to shut down a machine regularly for even a few minutes to replace faulty ejectors. Under these circiunstances, machine rehability and stability of operation are critical. For certain large or heavy objects a solenoid valve may be used to control a pneumatically operated flap or plunger to deflect rejected items. Specialised ejectors have been developed for pulps or slurries to remove rejects by suction and are mounted above a flat belt, downstream from the inspection unit.
