The invention concerns a method for discerning and sorting suitable products in a product flow having a certain concentration of a component versus anomalous products having this component in an anomalous concentration, whereby a beam of light strikes these products, and the absorption of this beam of light by said component in the products is detected by measuring the intensity of the light reflected by the products at least at a wavelength or in at least a wavelength band which is situated between 900 nm and 2500 nm in order to generate a detection signal on the basis of said absorption, whereby a product will be identified as an anomalous product if said detection signal exceeds a threshold value.

Method for discerning and sorting products whereby the concentration of a component of these products is determined

The invention concerns a method and a sorting apparatus for sorting potato products that are moved in a product flow through a detection zone, whereby irregular products are detected in the product flow and are separated from the product flow, characterized in that a light beam having a wavelength of in between 350 and 450 nm is directed towards said products in said detection zone and wherein the intensity of the light that is irradiated by the products is detected in a detection band from 460 nm to 600 nm, wherein a product is qualified as an irregular product and is separated from the product flow when said intensity is below a predetermined value. Further, the invention also concerns a method and a device for detecting the presence of solanine in potato products by means of fluorescence.

Method for sorting potato products and sorting apparatus for potato products

The invention relates to a sorting device and a method for sorting products () that are moved in a flow of products () through an inspection zone (), wherein a light beam () is moved over the flow of products such that substantially all products () are hit by the light beam () in said inspection zone (), whereby the light of this light beam () is, on the one hand, directly reflected as of the point of impact of the light beam on the products, and is, on the other hand, reflected in a scattered manner as of a zone round the point of impact following the diffusion of the light beam's light in the products, whereby the directly reflected light as well as the light which is reflected in a scattered manner is at least partly directed to a sensor element () of a detector (), whereby this sensor element () has at least two detection areas, wherein for each detection area a detection signal is generated corresponding to the intensity of the reflected light () that impinges upon this detection area.

The invention relates to a system comprising a broadband optical light source and a sorting device and more specifically to laser sorting devices. The object of the present invention is to provide a system comprising a sorting device with a light-source offering all wavelengths for the sorting process. This is solved by using an all fiber supercontinuum light source.
