Pasteurizing Tunnel

1. Applications of Pasteurizing Tunnels

• Juice and Tea Drinks – eliminate bacteria while preserving flavor and nutrients.
• Beer and Alcohol – stabilize product quality and prevent spoilage.
• Carbonated Soft Drinks (CSD) – ensure microbial safety in sealed cans and bottles.
• Dairy Products – milk and yogurt pasteurization for extended shelf life.
• Energy Drinks & Functional Beverages – maintain product safety and stability.

2. How Does a Pasteurizing Tunnel Work?

• Product Loading – sealed bottles or cans enter the pasteurizing tunnel on a conveyor.
• Heating Zone – hot water sprays gradually raise the temperature to a defined pasteurization level.
• Holding Stage – beverages are maintained at pasteurization temperature long enough to kill harmful microorganisms.
• Cooling Zone – water sprays reduce product temperature, ensuring safe handling and maintaining quality.
• Discharge – pasteurized products exit the tunnel, ready for labeling, packaging, and distribution.
• This step-by-step process ensures safe beverages with preserved taste, aroma, and nutrients.
