PasteurizerCheck

Tunnel pasteurizers play a critical role in food safety, product quality, and shelf‑life in food and beverage production. However, operational challenges such as corrosion, staining, slime formation, and scale buildup can negatively impact tunnel pasteurizer performance. These issues often contribute to increased bottle breakage, excessive water soiling, unstable temperature profiles, and rising chemical, water, and energy consumption.

Left unaddressed, these challenges can disrupt production, reduce line efficiency, and increase total operating costs — while also affecting product quality and process reliability.

Pasteurization performance depends on multiple interacting variables, including temperature, holding time, circulation flow rate, water quality, and chemical treatment. Ensuring consistent and efficient tunnel pasteurizer operation requires a structured, data‑driven approach.

What is Diversey PasteurizerCheck?

Diversey PasteurizerCheck is a tunnel pasteurizer performance assessment and optimization service and part of the Diversey Knowledge‑Based Services portfolio. It’s designed to help food and beverage producers improve tunnel pasteurizer efficiency, food safety, and operational performance while reducing total cost of operation.

This structured tunnel pasteurizer audit and analysis assesses equipment performance, chemistry, resource consumption, and operating practices. The outcome is a prioritized improvement plan focused on measurable operational and economic impact.

The assessment helps to:

• Ensure treatment solutions are suitable for tunnel pasteurizer operating conditions
• Limit equipment wear while maintaining consistent pasteurizer performance
• Verify correct operation of dosing and control equipment
• Reduce total cost of operation by optimizing boil‑out frequency and manual activities
• Identify and prioritize improvement opportunities
• Implement incremental changes that improve tunnel pasteurizer efficiency

How the Tunnel Pasteurizer Performance Assessment Works

With a focus on technical, environmental, and economic optimization, the service includes:

• An evaluation of general tunnel pasteurizer operating conditions to ensure proper performance
• A detailed on‑site assessment conducted by a Diversey specialist, including:
• System design review
• Audit of current treatment procedures
• Evaluation of tunnel pasteurizer water treatment and sustainability impact
• Identification of cost‑reduction and efficiency‑improvement opportunities

Clear Results and Actionable Insights

Following the assessment, you receive a detailed analysis and scorecard benchmarking your tunnel pasteurizer treatment program against three key performance pillars:

1. General Chemical Information
   Evaluation of the treatment program’s suitability and effectiveness.
2. Water and Dosing Information
   Assessment of water quality and dosing practices supporting pasteurizer performance.
3. Tunnel Pasteurizer Minimum Requirements
   Verification against established operational and performance expectations.

The final report includes clearly prioritized actions to improve tunnel pasteurizer efficiency, reliability, and cost performance.
