As Alejandro Palacios, Area Sales Manager at TOMRA Food for Spain and Portugal, explains: “X-ray technology, which can only detect stones, glass, metals, and ceramics, fell short of what they needed. Vicente Jiménez wanted the best for his customers, and when he saw all the possibilities that the Nimbus BSI+ offered, he realized that the potential benefits for his company were enormous. The two machines have been equipped with front cameras (BSI+ technology) and rear lasers with different colors: one with infrared and blue, the other with infrared and green. The result has been fantastic. LEGUMBRES SELECTAS SIERRA NEVADA has increased its client portfolio and currently has the most advanced technology in the sector across Europe.”
Having installed the new sorters to maintain its high quality and food safety standards, LEGUMBRES SELECTAS SIERRA NEVADA was faced with exceptional circumstances: an exponential increase in demand stemming from the lockdowns due to the COVID-19 pandemic.
“We have had a 30% increase in demand, and we estimate that it will stabilize at around 20% in the coming months. There has been a clear trend towards stocking pulses in homes because they are a staple food, nutritious, healthy, and very affordable. Their long shelf life (2-3 years) has made them one of the most sought-after products during these months of lockdown. Also, we see a shift from animal to plant-based protein. All of this has led to such a growth in demand that we have had to act, increasing production and strengthening our sales activity. We finished installing the two Nimbus BSI+ machines last January, and we had just enough time to get them up and running before the lockdown. Without them, we would not have been able to meet the exceptional demand we had,” Vicente Jiménez says without hesitation.
The BSI+ technology enabled LEGUMBRES SELECTAS SIERRA NEVADA to increase production and offer the best quality on the market and food safety, a cornerstone of its customer promise. The company is currently engaged in pursuing another critical objective: implementing a quality assurance and food safety system (SGCA/ GFSI) following the IFS Version 7 Quality Standards, ensuring transparency throughout the supply chain.
“With the Nimbus BSI+, we can achieve this certification today – and this is key for our international expansion.”

The Nimbus BSI+ detects the biometric characteristics of objects and can remove many foreign bodies and unwanted plant matter.
The traditional process begins with the chickpeas just arrived from the field. A preliminary cleaning process is followed by mechanical sorting with multiple machines, then a manual and visual inspection (which the company used to be conducted by a team of 12 people at LEGUMBRES SELECTAS SIERRA NEVADA). The main drawback is that this pulse’s density and color can be the same as those of a stone or other dangerous foreign bodies, making it very difficult to remove them from the product. This can lead to non-compliance with food safety regulations that require a maximum of 5 stones per ton. During the process, other unwanted bodies can also creep in – such as beans and other seeds of plant origin from previous harvests.
With TOMRA, the difference from the conventional process is remarkable. After preliminary cleaning and mechanical sorters, the chickpeas go through the Nimbus BSI+ sorters, ensuring 99.9% purity, and powerful metal detectors. Only a final visual inspection is needed, so the inspection team is reduced to 4 people). The company has been able to reassign the manual inspection team to valuable quality control tasks. The result is extremely precise, finetuned sorting that cannot be achieved with the human eye and an increase in the entire process’s efficiency.
As if this were not enough, the company has gained in quality of life. “On a personal level, in our daily life, the new equipment really has represented a turning point. The automation of the selection process leaves us more time to plan our workload and production load, and to carry out essential maintenance and cleaning tasks on Fridays, during the factory’s normal working hours,” says Vicente Jiménez.
The configuration of the programs is straightforward. “My team and I calibrate the machines. The Nimbus BSI+ is a very intuitive machine with great software, and changing programs is very easy. Today we only offer four varieties of pulses, but there are 37 more. Given how easy it is to adapt the programs, we will be able to consider expanding our product range in the not-so-distant future,” he points out. “Also, its minimal maintenance is a plus. We clean the machines with compressed air, and we have not needed to replace any parts since their start-up, with them working at 100% of their capacity.”
Finally, it is worth highlighting the equipment’s scrupulous selection ability, which reduces false rejection to less than 1%. “The most surprising thing is how concentrated the rejected product is. As the Nimbus BSI+ can remove many items at once, you’d think that you might risk losing good products but, with TOMRA, everything discarded is truly bad product,” says Alejandro Palacios.
TOMRA has been true to its philosophy of being by its customers’ side, listening to their needs, and adapting its technology to maximize their plants’ results. Even in the challenging time of the pandemic, nothing has stopped this ambitious and innovative project. The two companies have worked together to achieve the objective. “The TOMRA team is simply exceptional. They are always available and ready to take another step towards excellence. Without a doubt, I would recommend TOMRA and the Nimbus BSI+. Its addition to our selection process has meant a complete 180º turn, and it has opened up a very bright horizon for us.”
“This family business has established itself as a supplier to the most demanding and important clients on the market at domestic and European level. Furthermore, the involvement of Vicente Jiménez has allowed us to adapt our technology to a new application that we had not contemplated before. The entire installation turned out wonderfully – it’s worth showing off. In short, we are delighted to see how much we have been able to contribute not only on a business level but also on a human level.”
