Hi to all 

 

We have two CCP at Spice blends manufacturing industry

 

1.  Online Magnet at milling of Spices

2.  Temperature at Heat Sterilizer . 

 

Please let me know the followings

 

1. There is any standard Operating Procedure available  to monitoring the these CCPs.

2. What is acceptable level for Iron Particles and frequency of Monitoring. 

3. How to check the Strength of Magnet

Hi Sivac,

 

I don't have an SOP to give you regarding those CCPs, as it depends on your setup. We have rare earth magnets in our processing lines. In our dry product areas, the magnets just slide out of a casing and are checked and cleaned prior to start up. If there's any abnormal findings, integrity losses, or metal pieces found, those pieces are given to QA for investigation. The production will not start until everything is verified and approved. In our wet blending areas, we have magnets that sit inside filter housings, and are checked and cleaned each time the filters are checked. The same process happens if anything abnormal is found on the magnets there. As far as your temperature checks, the best setup is to incorporate data loggers inside your heating chamber. Ideally, you would have loggers at different areas of the chamber to show the heating is consistent throughout the chamber (or some sort of validation completed to show the heating is consistent if you only use one data logger). You can confirm your data loggers by using a thermometer or thermocouple to check temperatures. As far as frequency of monitoring, the data loggers are useful because you have continuous monitoring. You can verify the temperatures on a daily basis to make sure everything is reading properly.

 

However, I do find it interesting you are using a magnet rather than a metal detector as a CCP. Magnets don't typically have the greatest affinity to attract stainless steel pieces, so you may not be removing all the metals (especially if you use stainless steel equipment in your milling process). Your frequency of checks would probably be several times a day since you use your magnets as a CCP. We only check daily because our magnets are a CP and we have a metal detector and a screen further along in the process for dry blends. The acceptable size of particles may be found in regulatory guidance for your region. 

 

If you have a bar or tube magnet, you can use the Chatillon pull-test method. You place a metallic sphere at the end of a scale, and drop it onto the magnet. You pull away from the magnet at a right angle (90^o) until the magnet releases the sphere and record the reading on the scale. There's a resulting range your magnet should be in, to ensure the strength of the magnet is appropriate.
