Røntgenteknologi er i de senere år blevet anvendt i højere grad til on-line applikationer, blandt andet til kontrol af fødevarer. Røntgensystemer detekterer afvigelser i produktet. Når et fremmedlegeme detekteres vil systemets PLC styre signalgivning til sorteringsenheder tilkoblet produktionslinjen. Inspektionen sker oftest på u-emballerede eller individuelt pakkede produkter. Selvom der er
X-ray systems are widely applied for numerous applications relative to foreign body contamination of products. Typically, inspection is aimed at un-packaged and minor products. The problem is, that large products requires a higher energy and the detector must cover a larger area. This leads to lower contrast and reduced resolution.
This note focuses on chicken bone detection capabilities and provides an explanation of why some bones can be detected by X-ray inspection, whilst others cannot. The testing of an X-ray system is typically based on selecting small bones and cutting of small pieces of these bones, which are subsequently placed
In the past few years, X-ray technology has been developed towards a higher resolution and a higher contrast, retaining a high scanning speed. Therefore, more complex on-line product & process control, measurement and quantification tasks can be solved cost-effectively using advanced X-ray based sorting systems, in addition of course to
