The Nimbus free-fall machine features biometric signature identification (BSI) technology. This technology works by detecting the biometric characteristics of the nuts and raisins it scans and comparing them to features in its stored database to determine whether they should be accepted or rejected. Even before the BSI technology was developed, the multiple laser and high-resolution camera system permitted sorting by color, structure, size and shape in free-fall and could sort based on material type, using conventional near infrared (NIR) spectroscopy. The ejection system uses an optimal pitch for enhanced defect removal, and the machine can be equipped with a front sorting or rear ejection system for greater flexibility and reduced false reject rates. For some applications, a three-way sort is available, reducing handling and maximizing process flexibility.
