Method for sorting potato products and sorting apparatus for potato products

摘要

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.

主权项

1. A method for sorting potato products which are being moved in a product flow through a detection zone, whereby unwanted products in the product flow are detected and separated from the product flow, comprising:
in said detection zone, directing a beam of light having a wave length between 350 and 450 nm to said products, detecting intensity of the light which is emitted by the products in a detection band of 460 to 600 nm, detecting the presence of a fluorescence peak in said detection band, and qualifying a product as an undesirable product and separating said undesirable product from the product flow if said fluorescence peak is not present and said intensity is lower than a preset value, and maintaining a product in the product flow if the presence of said fluorescence peak is detected.
