Hi all,
I work for a small family owned operation that mixes and fills concentrates into small containers. In the past we have used a Metal detector to detect metal and a screen to remove foreign materials. The Metal detector is now no longer functioning and we would like to remove the MD from the process (was a CCP) and use the screen/filter as the CCP. I have a couple of questions relating to this:
1. The MD test pieces (FE, Non FE and SS) were 2mm and the screen size is 2mm. My issue is that the screen has been used for many years and I can not find a calibration certificate. Is there a simple in house test that I can use to calibrate the screen?
2. I have referenced literature for the validation of the screen, but I also have many in house records (years) where we have used the screen in conjunction with the metal detector and recorded our findings. I do not know where to start to write a validation report and correlate all of the data. Does anybody have template or example I can use .
Any advice on the above would be much appreciated.
Thanks
