Hi,
We recently purchased X-ray machine to detect foreign matters in baked cookies and which are aluminum foil wrapped. I need help with writing up the CCP work instruction for X-ray machine.
Another question is, X-ray machine can not detect aluminum due to low density. Should my product first pass through metal detector first to control aluminum foreign matters and other metals like Fe and S.S and then through the X-ray machine at last to control foreign matters other than metals? If I put the x-ray machine as the last step on this cookie line after labelling, how do I justify auditor that I am controlling the aluminum foreign matter.
Thanks
