I work at a Walnut Processing/Packing facility and we are currently installing a bleaching system. The system is used to clean/brighten the shell for in-shell walnuts.
I was wondering if anyone has any knowledge or experience with this process? I am not sure of the concentration of chlorine that should be used, how we should test it/document it, how often, and what other documentation or paperwork we may need for this type of system. I am assuming this needs to be in our FSM and we need documents to show we are regularly verifying the amounts of chlorine in the system.
I have researched online some but there isn't much information out there. I was hoping I could find someone here with some experience to help me out.
