Single kernel analysis and sorting platform
The QSorter technology is the heart of the new generation of sorting and analysis devices for grains, seeds, and beans. QualySense has pioneered this development with the scientific support of first-in-class research institutes in Switzerland and in United States of America. The main objective of the QSorter technology is to bring efficiency, productivity, and outstanding benefits in the grains, seeds, and beans world.
One by One Transport
Custom designed transportation system for increased accuracies
The QSorter is able to transport grains in a fixed position and on a one-by-one basis. This unique feature enables the precise measurements of biochemical properties and the accurate retrieval of shape, size, and color attributes. The transport is extremely fast. The current versions of the QSorter process, in average, about 50 kernels per second.

Innovative ideas for breakthrough results
Unlike other sorting devices, the QSorter collects a high-resolution Near-Infrared spectrum per each kernel. A light source illuminates the kernel: part of the energy is absorbed and part of the energy is reflected. The difference between the injected and the absorbed light is a function of the amount of biochemical properties that are present in the kernel. The spectra are composed of 512 points each, therefore giving precise details about the kernel inner composition.
The technology guarantees the possibility of detecting a wide palette of compositional properties per kernel, like moisture, protein and oil content, amylose, gluten, sugars, etc.
Full resolution Near-Infrared Spectra
Most image analysers see only one side of the kernel – the one exposed to the camera. We developed an innovative setup that allows us to see the surface in it’s integrity – imagine how awesome that is! Wide-range optics designed to cover almost 100% of the kernel surface for more accurate image analysis. CCD high-speed color camera processing up to 120 frames/second, with flexible illumination setups help you see the unseen.
The fixed position of the kernel allows the camera to record very precisely physical attributes such as shape, size, length, area, and color. Additionally, further analysis is applied to retrieve additional physical information such as broken and shrivelled kernels.
Spectral data are processed to define the amount of each biochemical property in a kernel. The calibrations are developed on a per kernel basis. Single spectra measurements are taken for each grain; subsequently, the scanned kernels are analyed with classical laboratory wet chemistry techniques to establish the “true” amount of the biochemically property. Finally, various algorithms are applied to correlate the spectral measurements to the laboratory measurements.
The processing of the color images is performed with the support of artificial intelligence algorithms. Several metrics are extracted from each picture and the computer brain computes classification rules aiming at guaranteeing high sensitivity and high repeatability of the algorithms.
Precise size and color measurements
3D Imaging for higher accuracies
The QSorter has an excellent sorting efficiency. This is due to the single kernel transport and to the high precision of the sorting mechanism, which is based on pneumatics. This accuracy is key to a productive process, as no re-passes of the reject are needed to improve the overall efficiency of the device. In the long run, this enables a dramatic increase in productivity and in value.
Reporting of Results
The QualySense team has struggled to present the results of the analytical and sorting process in a very intuitive and simple way. The experiment results are reported in the touch screen graphical user interface (GUI). For each parameter, several statistical metrics are reported such as mean value, count, and standard deviation. The final experiment report is saved on the QSorter hard-disk and can be printed in the most known formats.
