The Plate Pasteurizer is a highly efficient and energy-saving thermal processing equipment designed for liquid foods such as milk, juice, beverages, alcohol, and other fluid products. It performs pasteurization and heat exchange through a plate heat exchanger, ensuring precise temperature control, compact structure, and easy cleaning. The system can be configured for automatic, semi-automatic, or manual operation and is compatible with filling systems, storage tanks, and CIP cleaning units.
As a professional Plate Pasteurizer Manufacturer, YME provides high-efficiency thermal processing solutions for dairy, beverage, and liquid food industries. Our plate pasteurizer is a core component within complete Milk sterilization and cleaning equipment systems, designed to ensure food safety, consistent product quality, and energy-efficient operation across modern processing lines.
Widely applied in milk processing plants, yogurt production lines, juice and tea beverage factories, and plant-based drink facilities, YME plate pasteurizers are engineered for continuous production, precise temperature control, and seamless integration with CIP cleaning systems and downstream filling equipment.
The plate pasteurizer operates using a multi-layer stainless steel plate heat exchanger, where hot and cold fluids flow through alternating channels to achieve rapid and efficient heat transfer.
A typical milk pasteurization process includes:
Preheating (Regeneration Section)
Incoming milk is preheated using heat recovered from outgoing pasteurized milk, significantly reducing energy consumption.
Heating Section
Milk is heated to 72–85°C using hot water or steam to reach pasteurization temperature.
Holding Section
The product flows through a holding tube for 15–30 seconds, ensuring effective destruction of pathogenic microorganisms.
Cooling Section
Milk is cooled first through regeneration, then further chilled with cold or chilled water to 4–5°C, ready for filling or storage.
This HTST (High-Temperature Short-Time) process guarantees food safety while preserving flavor, nutrients, and texture.
Feed Pump
Sanitary centrifugal pump ensuring stable flow and system pressure.
