Abstract
A new NIR measuring process and apparatus which can measure both floury commodities and whole kernels, and other constituents of pourable foodstuff products in-line. A large number of individual measurements are made with a measuring time per individual measurement of less than 100, preferably 50, milliseconds and these are statistically averaged by a computer. A rotating filter principle as well as the diode array principle can be used. For grain products, the protein, water and ash content can be determined with a high degree of accuracy. The measured values are directly usable, for the control and regulation of corresponding foodstuff parameters.
