Used UHT Milk Preparation Room GEA Finnah 13000 l/h

The Used UHT Milk Preparation Room GEA Finnah 13000 l/h efficiently processes pre-pasteurized UHT milk using indirect heating. This system has an operational capacity of 13,000 l/h, ensuring high-quality and long-lasting milk production. This UHT line handles milk with 1.5% and 3.5% fat content while meeting strict hygiene standards.

Structure of the Used UHT Milk Preparation Room GEA Finnah 13000 l/h

The Used UHT Milk Preparation Room GEA Finnah integrates key technological units that work together to ensure an efficient sterilization process, energy savings, and optimal product handling. The plant consists of several main components that contribute to its performance.

Tubular Heat Exchanger (GEA Finnah)

The tubular heat exchanger performs indirect heating of the milk at a pressure of 23 bar in the shell and 50 bar in the tubes, ensuring uniform heat distribution and safe processing. The system optimizes energy transfer and maintains consistent product quality.

Pumps

• Fristam CF 050-200A – 13.5 m³/h, 5.5 kW power
• Grundfos CRN 16-160F – 13.2 m³/h, 15 kW power
• Grundfos CRN 16-100A – 16 m³/h, 11 kW power

These pumps maintain constant pressure and ensure continuous milk transportation through the system.

Flowmeter (Krohne H 250)

The Krohne H 250 flowmeter precisely monitors milk flow, optimizing process control and ensuring consistency in production.

Holding Tubes

The Used UHT Milk Preparation Room GEA holds milk at high temperatures for 120 seconds in the main section and 1 second in the rapid section. This ensures proper microbial inactivation, achieving effective sterilization.

Sterilization Process

• The system does not have a separate sterilizer.
• Instead, sterilization occurs through indirect heat exchangers, which raise the milk temperature to ~140°C.
• After sterilization, the product is gradually cooled to ~25°C before exiting the system.

This process is standard in UHT indirect heating systems, where the milk does not come into direct contact with the heating medium (e.g., steam or superheated water).

Homogenizer

The line includes an APV Schröder Gaulin high-pressure homogenizer, model 3434 MC 45-3TPS, with a capacity of 13,000 liters per hour and a maximum pressure of 220 bar. This homogenizer is equipped with a 110 kW Danfoss frequency converter and is installed in a separate panel.

Control Panel (Siemens S7 PLC and Simatic OP37)

The Siemens S7 PLC and Simatic OP37 operating panel provide fully automated process control, reducing manual interventions and improving precision.

Regenerative Circuit and Interconnected Valves

The regenerative circuit enhances energy efficiency by recovering heat, while the interconnected valves ensure smooth flow transitions within the system.

Operational Process of the Used UHT Milk Preparation Room GEA

1. Milk enters the system at ~18°C.
2. The regenerative circuit initially pre-heats the milk.
3. The tubular heat exchanger raises the temperature to ~140°C.
4. The product remains at sterilization temperature for 120 seconds in the main section and 1 second in the rapid section.
5. The milk is gradually cooled to ~25°C before packaging.

Energy Consumption of the Used UHT Milk Preparation Room

• Steam: 400-800 kg/h at 6-10 bar
• Hot Water: 15 m³/h
• Process Water: 3-6 m³/h at 2-4 bar
• Cooling Water: 5 m³/h at 2-4 bar
• Ice Water: 2-4 bar
• Compressed Air: 4 Nm³/h at 6-8 bar
• Electric Power: 35 kW (excluding homogenizer)

Additional Machinery in the Used UHT Milk Preparation Room

The Used UHT Milk Preparation Room GEA also includes:

• Filters and Separators (including an activated carbon filter and various separators)
• CIP System (Clean-in-Place for automated cleaning)

Final Considerations of the Used UHT Milk Preparation Room GEA Finnah 13000 l/h

The Used UHT Milk Preparation Room GEA Finnah 13,000 l/h ensures efficient UHT milk processing with optimized energy consumption. Its flexibility makes it an ideal solution for balancing high performance with cost efficiency.
