Nimbus bsi sorting machine by tomra

The Nimbus BSI is a real breakthrough for nuts and raisin processors.

With a combination of various sorting technologies, the Nimbus free fall sorting machine with Biometric Signature Identification (BSI) meets the continuously high requirements of the food industry and individual processors for safe and excellent food quality by removing unwanted material.

The BSI technology is the latest spectral based optical platform, introduced to identify the material’s unique fingerprint. This creates a new generation of sorting opportunities for nuts, dried fruit, potatoes and other commodities.


TOMRA Sorting Solutions is proud to announce that it has been presented with the 2015 Innovation Award at the World Nut and Dried Fruit Congress which took place in Antalya, Turkey, for its groundbreaking Nimbus BSI sorting technology. Read all about it in the press release.


One of the major problems Andersen & Sons faced in the past was their inability to identify defects using just laser sorters. Having outgrown its latest walnut sorting machine, they needed something that would meet the company’s specific demands. Discover all about Andersen & Sons buyer's journey and find out why they decided to partner with TOMRA.

“We turned to TOMRA because when looking at the challenges ahead, it soon became clear that TOMRA was going to meet our high requirements, and was able to achieve the quality and the high throughput in a timely manner. Their years of expertise led to us developing the best walnut sorting solution for our needs,” said Scott Brown, Production Manager at Morada Nut. Read Morada Nut's testimonial here.

“By implementing TOMRA’s Nimbus BSI in our almond processing lines, our company Stewart & Jasper gained enormously. Our throughput has increased immensely and we have seen our labor expenses drop. On top of that, our product quality has improved. We have thoroughly researched the sorting industry, and it goes without saying that TOMRA’s Nimbus BSI is unmatched,” said Jim Jasper, Owner Stewart & Jasper, USA.

“To assist in our global growth we decided to partner with TOMRA. This will help us to provide high volumes of high-quality raisins,” says Türkan Orhan, general manager at Orka Tarim, Turkey. Read his testimonial.

Sensor Technology

The Nimbus BSI free-fall laser sorting machine combines the efficiency of laser detection with the BSI module, specifically designed to identify the material’s unique fingerprint. In addition to these sorting methods, the Nimbus is able to sort based on biological characteristics, such as chlorophyll (Fluo™), mycotoxins (Detox™), water and oil content. The ejection system uses an optimal pitch for enhanced removal of defects. The Nimbus BSI can be equipped with a Rear Ejection System (RES™) with small pitch ejectors for greater flexibility, lower false reject and improved yield.
