Continuous Plate Pasteurizer for Milk and Ice Cream Line

Product introduction of Continuous Plate Pasteurizer

Engineered for continuous thermal processing, this plate pasteurizer delivers controlled heating and cooling for milk, ice cream mix, and other liquid dairy products. The system processes up to 3 t/h and uses a 20 m² plate heat exchange area to provide rapid thermal transfer within a compact production footprint. Product passes through separate regeneration, heating, holding, and cooling stages, allowing recovered heat from outgoing product to preheat incoming liquid and reduce utility demand. Precise temperature regulation helps maintain repeatable processing conditions, while automated monitoring supports dependable operation throughout production. Sanitary stainless steel product pathways, hygienic pumps, valves, and piping simplify routine cleaning and support integration with CIP systems. The unit requires approximately 156 kg/h of steam, uses 6 kW installed power, and has approximate dimensions of 2000 × 2000 × 2200 mm. Its modular configuration can be integrated with homogenizers, storage tanks, fillers, and downstream dairy processing equipment for complete production lines.

Three-Stage Thermal Processing

The plate heat exchanger is arranged to perform three essential thermal functions: preheating, pasteurization, and cooling. Product moves continuously through dedicated heat transfer sections instead of being heated in a batch vessel, helping shorten processing time and maintain steady production.

Rapid Plate Heat Transfer

Closely arranged stainless steel plates create a large heat transfer surface within a relatively compact unit. Alternating product and utility channels promote efficient indirect heat exchange without mixing the processing liquid with heating or cooling media.

This configuration is particularly suitable for dairy applications requiring fast temperature changes and controlled product handling.

Heat Regeneration for Energy Savings

Thermal energy from the outgoing hot product can be transferred to the incoming cold product before final heating. This regenerative process reduces the amount of external energy required to reach the target pasteurization temperature.

Benefits include:

• Lower heating utility demand
• Reduced cooling load
• Improved thermal efficiency
• More economical continuous production
• Better utilization of recovered process heat

Typical Processing Flow

Product Feeding → Regenerative Preheating → Final Heating → Holding → Heat Recovery → Final Cooling → Storage / Further Processing

Additional equipment such as a balance tank, homogenizer, aging tank, storage tank, or filling machine can be incorporated according to the final product and production arrangement.

Suitable Applications

Pasteurized Milk
Provides continuous controlled heat treatment before cooling, storage, or filling.

Ice Cream Mix
Suitable for thermal processing of formulated dairy mixes before cooling, aging, and freezing.

Flavored Milk
Supports pasteurization of blended milk formulations before downstream packaging.

Dairy Beverage
Provides controlled heating and cooling for various pumpable dairy-based drinks.

Yogurt Milk Base
Can prepare milk for subsequent fermentation when matched with the required process conditions.

Liquid Dairy Mix
Suitable for other flowable dairy formulations requiring continuous thermal treatment.

Designed for 3 t/h Continuous Production

With a nominal processing capacity of 3 t/h, the pasteurizer is suitable for dairy plants that require a continuous alternative to batch thermal processing. Continuous product movement supports stable throughput and facilitates connection with upstream and downstream equipment.

The 20 m² heat exchange area provides substantial thermal transfer surface while keeping the complete system relatively compact.

Modular Dairy Line Integration

The pasteurizer does not need to operate as an isolated machine. Its skid-based configuration can form part of a larger processing line together with:

• Balance tank
• Homogenizer
• Product storage tank
• Ice cream aging tank
• CIP cleaning system
• Cooling system
• Filling and packaging equipment

This allows the pasteurization section to be adapted to different factory layouts and production requirements.

FAQ

Q: What is the processing capacity of this plate pasteurizer?
A: The standard configuration shown here provides a nominal processing capacity of 3 t/h. Other capacities can be configured according to production requirements.

Q: Can this pasteurizer process both milk and ice cream mix?
A: Yes. It can be configured for milk, ice cream mix, flavored dairy beverages, and other pumpable dairy formulations.

Q: Does every dairy product use the same pasteurization temperature?
A: No. Required temperature and holding time depend on product composition, formulation, and processing requirements. The operating parameters should therefore be configured for the specific product.

Q: How does the system reduce energy consumption?
A: The regeneration section transfers heat from outgoing pasteurized product to incoming cold product, reducing the external heating and cooling loads.

Q: Can the equipment be connected to a CIP system?
A: Yes. The product circuit can be designed for CIP circulation to simplify routine cleaning and sanitation.

Q: Can a homogenizer be integrated into the processing line?
A: Yes. A homogenizer can be incorporated at the appropriate stage according to the dairy product and required process flow.

Q: Can the pasteurizer connect directly with filling equipment?
A: Yes. Depending on the required outlet temperature and production process, the system can discharge to a storage tank, aging system, or downstream filling line.
