Production system with near-infrared spectrometer

A production system comprising a plurality of production lines in each of which a bulk product is conveyed, comprising:

• a sampling arrangement for automated collection of material samples of product flows of bulk products from a plurality of sampling positions by means of automated sampling devices, the plurality of sampling positions comprising at least one sampling position of each of said product lines, and providing the material samples in separate sample containers to an optical analysis system of the production system,
• wherein the optical analysis system comprises at least one near-infrared spectrometer,
• a controller having a data communication interface connecting with a data communication interface of the near-infrared spectrometer, wherein the controller is adapted for transferring data identifying the material sample of a sample container to a controller of the near-infrared spectrometer prior to conducting an optical analysis of the material sample in the sample container,
• the optical analysis system being arranged for conducting an optical analysis of the material sample in sample containers through a transparent bottom part of the sample container, process the analysis results using said data identifying the material sample and providing an analysis output accordingly to the controller,
• wherein the controller is adapted to control the operation of at least one production devices of the production lines in response to the received analysis output from the near-infrared spectrometer.
