Bühler launches SORTEX H SpectraVision

22 June 20224 min reading

Swiss Bühler Group has launched its latest optical sorter for wheat, rye, oats, grains, coffee and pulses: the SORTEX H SpectraVision. Powered by brand new MerlinAi sorting algorithms, the solution pushes optical sorting to the next level of usability, performance, and product traceability.

Using the best of British and Swiss engineering know-how, the SORTEX H SpectraVision is the result of Bühler’s 75 years of experience in optical sorting. It offers three key benefits for customers: unmatched ease of use, high performance, and enhanced connectivity, contributing to increased sustainability. 

Processors today must tackle an ever-increasing number of defects as a result of climate change and pesticide reduction. With its individual defect removal control, the SORTEX H enables processors to maintain sort quality with ease.

The SORTEX H also delivers up to 50% higher reject concentrations. Supplying maximum yields is in line with Bühler’s goal to reduce energy, waste, and water by 50% in its customers’ value chains by 2025 and to develop sustainable solutions to feed the world population of 10 billion by 2050.  

Additionally, enhanced connectivity increases value for processors. Over 500 data points can be downloaded every second and sent to Bühler Insights to optimize and track performance. Processors can monitor and control their machine performance from anywhere in the world, in line with Industry 4.0 standards. Real-time tracking of sorting performance and emergency warnings are also possible thanks to the SORTEX Monitoring System. 

MerlinAi: innovation, not magic 

The SORTEX H SpectraVision, which is capable of handling a range of applications including: wheat, rye, oats, grains, coffee and pulses, is powered by brand new MerlinAi sorting algorithms. “MerlinAi is the new brain of Bühler’s SORTEX optical sorting machines,” says Melvyn Penna, Product Manager at Bühler. “Its advanced multi-layer sorting algorithms ensure a consistently higher yield for processors, as less good product is lost in the reject stream.”

Superior defect reduction means accept quality can be met even with input material of a lower quality. “These all-new calibration and product tracking algorithms ensure that machine performance remains steady and high, giving processors greater flexibility,” says Penna. 


One customer that has been enjoying the benefits of the SORTEX H SpectraVision is Harivenasa. As Spain’s first oat mill, the company specializes in producing and supplying high-quality oats and other cereal-based products, maintaining an ethos that good health can be achieved by enjoying life and food.  

Harivenasa had a seven-module SORTEX H SpectraVision machine installed last year in its brand-new oat mill. “We’re extremely happy with the SORTEX H because it’s very efficient, boosts our productivity, and we get much better quality now than we previously did in terms of unhusked grains, defects, black spots and so on,” says Alberto Loizate, Managing Director, Harivenasa - Alea. Since installing the machine, Harivenasa has seen improved quality in its oats and is now looking to enter new markets in new countries.

Ease of use is also a major benefit.  “Our staff say that it’s much easier to navigate around the software and to maintain the machine. They also tell us that it’s easier to change parameters. In short, the SORTEX H makes their lives a lot easier,” says Loizate. He adds: “The return on investment will also be very short. We’ve already seen great quality with very low reject of product.The sorter has a lot of brand-new features, and it works with the latest remote connections and Bühler insights. With Bühler Insights, the machine is ready for the future.”

The SORTEX H SpectraVision, which is built and validated at Bühler’s London facility, has been installed at numerous customer sites around the world and is available for purchase globally. It is available with up to seven chutes. It was introduced to processors during a number of application- and region-specific webinars over the last couple of months. It was also showcased at this year’s ISF World Seed Congress in Barcelona as well as the IAOM in North America and IPACK-IMA in Milan, where it received a great response.  

Bühler SORTEX will be sharing the success of these over the coming months. For now, the SORTEX H can be examined live at any of Bühler’s test centers worldwide, or via video stream.
