The Duravant family of operating companies serve the food processing, packaging and material handling segments.

Pre-package Pasteurization


We offer a wide range of versatile, custom-built pasteurization solutions designed around your protocol and process flow. Whether you’re pasteurizing vertical form-fill-seal pouches or packaged deli products, our solutions are recognized by USDA Food Safety and Inspection Service and have been validated by third-party testing laboratories. With a broad portfolio of pasteurization solutions, our team of technical advisors help processors identify the most appropriate process to achieve lethality while maintaining high product quality.

Post-package pasteurization isn’t always a viable solution if there are footprint constraints at the end of your line or double heating the product is not an option. With proper handling and our pre-package pasteurization solutions, you can still reduce the risk of cross-contamination and increase shelf life. By pasteurizing your product before packaging, the need for post-pasteurization bags is eliminated which increases your profitability.

Benefits of Pre-package Pasteurization

Our pre-package pasteurization solutions reduce the risk of cross-contamination and increase shelf-life. By pasteurizing your product before packaging, the need for post-package pasteurization bags is eliminated which increases your profitability.

  • Combined browning and pasteurization in a compact footprint.

Product is pre-cooked and chilled before it passes through our pasteurization process. Short residence times allow your product to retain its core temperature so it’s ready for immediate packaging upon exit.

  • Entire product surface is exposed to direct flame or infrared.

Complete lethality is achieved in just one pass. These systems also offer the benefit of color and flavor development while pasteurization takes place.
