Plate Pasteurizer with Heating and Cooling for Dairy Line

Plate Pasteurizer Product Introduction

This plate pasteurizer is engineered for continuous thermal treatment of milk, dairy beverages, ice cream mix, and other pumpable liquid foods. With a processing capacity of 2 t/h and a 13 m² heat exchange area, it provides efficient heat transfer while maintaining a compact equipment footprint. Product can enter at approximately 4°C, undergo regenerative preheating, and be heated to around 65°C before optional homogenization. It then reaches 85–95°C for approximately 15 seconds before rapid cooling to about 4°C, with actual settings adjusted according to the product recipe and required process. A balanced product supply, hot water circulation, steam and water mixing, sanitary pumps, valves, and stainless steel piping support reliable continuous operation. Full automatic PLC touch-screen control or semi-automatic PID control can be configured. High heat recovery reduces utility demand, while straightforward operation, accessible components, and integration flexibility make the system suitable for modern dairy processing lines and processing plants.

Process Flow

Cold Product Feeding → Regenerative Preheating → Preheating to Approx. 65°C → Optional Homogenization → Final Heating → Holding → Heat Regeneration → Final Cooling → Storage or Filling

This configuration allows heating, optional homogenization, pasteurization, energy recovery, and cooling to operate as a coordinated continuous process.

Main System Components

The pasteurization system can be configured with a plate heat exchanger, product balance tank, hot water balance tank, hot water circulation pump, sanitary product pump, steam-water mixing unit, electrical control cabinet, temperature instruments, sanitary valves, and stainless steel process piping.

The modular arrangement also makes it easier to connect upstream and downstream processing equipment.

Production Line Integration

Rather than operating only as an independent pasteurizer, the system can become part of a complete dairy processing line. Depending on the production process, compatible equipment can include:

• Milk Separator — supports cream separation, clarification, or milk standardization before thermal processing.
• Homogenizer — reduces fat globule size and improves product consistency when homogenization is required.
• Deaerator — removes entrained air to support product quality and downstream processing.
• Evaporator — enables concentration processes where higher solids content is required.
• Storage Tank — provides sanitary buffering before or after pasteurization.
• Filling Machine — allows processed product to move directly toward packaging after suitable cooling or downstream treatment.

Suitable Products

Fresh Milk — continuous thermal treatment before refrigerated storage or filling.

Dairy Beverage — suitable for formulated liquid dairy products requiring controlled heating and cooling.

Ice Cream Mix — provides thermal processing before subsequent cooling, aging, and freezing stages.

Flavored Milk — handles pumpable milk-based formulations under controlled pasteurization conditions.

Liquid Dairy Mix — suitable for various blended dairy formulations with adjustable process settings.

Juice and Liquid Food — can also be configured for compatible pumpable beverages when appropriate temperature and holding parameters are selected.

Technical Specifications

Main Features

1. 2 T/H Continuous Processing Capacity

FAQ

Q: What is the processing capacity of this plate pasteurizer?
A: The standard configuration described here processes approximately 2 t/h. Other capacities can be engineered according to production requirements.

Q: Can the pasteurizer be connected to a homogenizer?
A: Yes. The process can be arranged so the product is preheated before entering a homogenizer and then returned for final pasteurization and cooling.

Q: Are 85–95°C and 15 seconds fixed processing parameters?
A: No. These are reference conditions for this configuration. The required temperature and holding time depend on the product formulation, processing objective, and applicable food safety requirements.

Q: Can the product be cooled directly after pasteurization?
A: Yes. Regenerative cooling can recover useful heat first, followed by final cooling with chilled water or another suitable cooling medium.

Q: What control systems are available?
A: The system can be equipped with full automatic PLC touch-screen control or a semi-automatic PID control configuration.

Q: Can this equipment be integrated into a complete dairy production line?
A: Yes. It can work with separators, homogenizers, deaerators, evaporators, storage tanks, filling equipment, and other compatible processing machinery.
