Used Diary Pasteurisation unit TETRA PAK 20000 l/hr

The Tetra Pak Tetra Therm Lacta pasteurisation unit, with a capacity of 20,000 liters/hour, processes liquid dairy products continuously. It efficiently handles market milk, cheese milk, yogurt milk, cream, and ice cream mixes. Moreover, this model combines high energy efficiency, modularity, and advanced automation.

Working Principle of the Used Diary Pasteurisation unit TETRA PAK

To begin, the process involves pre-sterilization, where the unit circulates hot water for 20 minutes. Subsequently, the system stabilizes at the production temperature. If production delays occur, operators can activate a hibernation mode, which reduces energy consumption by up to 85%.

During production, the balance tank first receives the product, ensuring gentle handling and high cleanliness through integrated CIP devices. Then, the Tetra Plex plate heat exchanger uses the outgoing pasteurized product to regenerate heat, completing the initial heating phase. In addition, an indirect hot water circuit performs the final heating phase.

The holding tube keeps the product at the required temperature for the specified time. Importantly, if the pasteurization temperature drops below the set level, a flow diversion valve immediately redirects the product back to the balance tank.

Capacity and Performance

This unit processes up to 20,000 liters of milk per hour. Furthermore, it maintains standard pasteurization parameters based on the type of product, including:

• Milk pasteurization temperature: 74 °C for 15 seconds.
• Outlet temperature: 4 °C.

Additionally, the thermal regeneration system achieves 90% efficiency, significantly minimizing energy use.

Technical Features

This unit includes several key components. First, the balance tank manages product levels automatically. Next, a plate heat exchanger handles cooling, heat regeneration, and final heating. Moreover, a sterilization system features a continuous holding tube. The automated control unit (PLC) provides a user-friendly interface for monitoring and managing processes. Finally, pneumatic sanitary valves and stainless steel AISI 316 piping ensure durability and reliability.

Moreover, users can connect optional subunits, such as homogenizers, separators, and fat standardization units, to enhance functionality. Therefore, this system offers flexibility for various production needs.

Cleaning and Maintenance

For cleaning, the Tetra Therm Lacta performs fully automated CIP cycles using alkaline and acidic detergents. During production, operators may initiate an intermediate cleaning (IC) process to extend uptime. Simultaneously, the system logs data on temperatures, alarms, and cleaning cycles automatically.

In contrast to manual cleaning methods, the automated processes reduce downtime. Consequently, production resumes quickly after cleaning, thereby improving efficiency.

Advantages of the Used Diary Pasteurisation unit TETRA PAK

This pasteurisation unit delivers exceptional reliability, food safety, and ease of operation. Moreover, its modular design allows quick adaptations to changing production needs. Similarly, the system integrates seamlessly with upstream and downstream equipment to support efficient workflows.

Ultimately, the 20,000 l/hr model provides manufacturers with a scalable, sustainable, and energy-efficient solution for liquid dairy product pasteurization.
