Method and a system for handling sample materials, e.g. in mixing plants, for central analysis of the samples

Abstract From the Canadian patent

Samples taken automatically and frequently from the outlets of silos in mixing plants, e.g. for fodder mixtures, are brought unwrapped and successively to an automatic NIR analysing station through a pneumatic conveyor system with substantial common pipe stretches between that station and the single samplers. The associated risk of contamination of the samples is counteracted by taking out and conveying sample portions which are much larger than what is required for the analysis itself, and the large sample portions are not wasted as, they are returned to their silos of origin through another pneumatic conveyor system. It is hereby possible to operate with a real on-line analysing and thus …
