Abstract

A process and device for collecting measurement samples from a flow of bulk materials, in particular foodstuffs and feedstocks, in order to determine one or several characteristic values of the material, such as protein content, moisture, colour, ashes, granulation, etc. At least one first partial flow is derived from the flow of bulk materials and at least this partial flow is reunited with the flow of bulk materials, the first partial flow or a further partial flow derived from the first is at least temporarily dammed, a small percentage of the dammed partial flow is at least in part continuously extracted as measurement sample and this measurement sample is then conveyed through a measuring device, preferably by NMR or NIR, to determine the characteristic values of the material.
