Heating Section

The heating section is a critical component of the Integrated Beverage Pasteurization and Cooling Tunnel System. Its primary function is to uniformly and precisely elevate the temperature of the beverage product (such as juice, milk, or other liquid drinks) to a specific target range, typically between 72°C to 95°C (161°F to 203°F), to achieve effective pasteurization. This process eliminates pathogenic microorganisms and deactivates enzymes, thereby ensuring product safety and extending shelf life while maintaining the beverage's sensory and nutritional qualities. The section is designed for controlled, efficient heat transfer as the product flows through the tunnel.

The heating section operates by transferring thermal energy to the beverage product. This is typically achieved through indirect heat exchange. The beverage flows through a sanitary tube or plate heat exchanger. A heating medium (such as hot water or steam) circulates on the opposite side of the heat transfer surface, warming the beverage without direct contact. Precise temperature control systems (sensors, controllers, and regulating valves) maintain the target temperature throughout the section to ensure consistent pasteurization efficacy.
