Highly efficient pasteurizers can create corrosion problems even when tunnel pasteurizers are constructed from 304 stainless steel. Total organic carbon (TOC) levels increase over time when pasteurizer water consumption is low, as in the case of highly efficient pasteurizers. This creates a buildup of chloramines that eventually leads to destruction of the oxide layer that protects the stainless steel from corrosion. The vapor areas of the tunnel pasteurizer (areas above the water line or areas not continuously in contact with pasteurizer water) will begin to show signs of corrosion in high-TOC environments. This presentation describes the options available to eliminate or reduce TOC levels and covers the most effective ways to clean and restore the corroded areas of the pasteurizer and recondition those surfaces so they are adequately protected from further degradation.
