Currently using PAA in the hydrocooler. Issue is that it is causing some corrosion to the cooper pipes.
here is the process- produce from the field- go through a flume system/ brushes- to remove dirt and organic matter. Clean produce drops into the hydrocooler to get core temperature down. Basically roll through very quickly. Then go through a series of sprays ( potable water) before packed.
All water entering systems is potable. Water is changed daily and it is not recycled.
So with the issue of corrosion- is it mandatory to treat the hydrocooler water? Can the carrots go through a single spray system after the hydrocooler and spray with PAA then or is it required to treat any water that comes into contact with produce?
Thanks
