Case: Pasteurization

Multi-section plate heat exchanger is designed for pasteurization.
1, Cold milk is pumped to section Ⅱ, and pre-heated to 55℃;
2, The 55℃ milk go through homogenizer, and go back to the plate heat exchanger section Ⅰ, which is heated to 75℃ for pasteurization by hot water or steam;
3, The 75℃ pasteurized milk go back to section Ⅱ to heat up the cold raw milk, and the temperature decrease a little bit.
4, The pasteurized milk is cooled down to 4℃ by cold water in section Ⅲ.
