The company operated four continuous production lines, each with 3 tanks. Each day the tanks were shut down for cleaning, which took a minimum of one hour. In many cases cleaning took longer because of the frequent clogging of the spray balls. There was also additional manual cleaning needed from time to time when the spray balls could not remove the built up residue. The company turned to Gamajet rotary impingement tank cleaners, and the results were much more beneficial than expected. The solution was a Gamajet Aseptic VI rotary impingement tank cleaner operating at 115 psi and 15 gpm. Cleaning began with a 2 minute pre-rinse to remove the bulk of the residue followed by a five minute re-circulated wash with caustic and a final two minute rinse.
