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.
Working Principle
The plate pasteurizer uses a multi-layer stainless steel plate heat exchanger where heat is transferred between hot and cold fluids to achieve heating and cooling. A typical pasteurization process for milk includes the following stages:
1. Preheating – The incoming milk is preheated by the hot outgoing milk.
2. Heating – Milk is heated to 72–85°C by hot water or steam.
3. Holding – The product is held for 15–30 seconds to destroy harmful microorganisms.
4. Cooling – The milk is cooled first in the regeneration section, then with cold or chilled water to 4–5°C for filling or storage.
