procedure and system for the handling of proevematerialer, for example. in blandingsanlaeg for central analysis of the samples

摘要

Samples taken automatically and frequently from the outlets of silos 4 in mixing installations, e.g. for fodder mixtures, are brought unwrapped and successively to an automatic NIR analysis station 72, 26 through a pneumatic conveyor system with substantial common pipe lengths between said station and the individual samplers 34. The associated risk of contamination of the samples is counteracted by taking out and conveying sample portions which are much larger than is required for analysis itself, and the large sample portions are not wasted, as they are returned to their silos of origin through another pneumatic conveyor system 90. It is thus possible to operate with true on-line analysis and thus, with computer support, to effect necessary changes in the mixture recipes almost immediately in response to deviations in the analysis results. Various specialized sample-handling equipment for assisting operation is disclosed. IMAGE
