Sorting ejection system

The ejection system must be capable of physically removing unwanted product items from the main accept stream. The ejection process typically takes place while the product is in free fall accept particles are allowed to continue along their normal trajectory, and rejects are deflected into a receptacle. Deflection is usually achieved by emitting short bnrsts of compressed air through nozzles aimed directly at the rejects, althongh large or heavy objects (e.g., whole potatoes) may reqnire some sort of piston-operated device to mechanically deflect the rejects.
