Method for gasket plate heat exchanger for milk pasteurization

Milk is a well-known drink, but in the process of dairy production and manufacturing, can not be separated from such a process - pasteurization, as the name suggests, pasteurization is a process method to kill the bacteria in the milk for the purpose of killing, this method through the milk quickly heated to a high temperature state, and then quickly cooled to a low temperature state, through a sharp temperature change, so as to kill the bacteria in the milk. But do you know the equipment that pasteurizes? This is a plate heat exchanger for milk.

Milk plate heat exchanger, generally three-stage, respectively preheating section, heating section, cooling section. The preheating section not only exchanges the cold milk into the heat exchanger with the hot milk that will be cooled rapidly in the heat exchanger, but also preheats the cold milk. This process is called the preheating section, and the preheating section is the heat transfer between the milk and the milk, which plays a role in energy saving and environmental protection. This design scheme also helps to reduce the number of plates of the plate heat exchanger. So as to achieve the purpose of saving economic benefits.

The heating section is to heat the milk after the preheating section with hot water or saturated steam, and heat the milk to 95 ° C, so as to achieve the purpose of sterilization. The cooling phase is the rapid cooling of hot milk to 0-5 degrees Celsius through a glycol solution.

Sanitary Food Plate Heat Exchangers

The method of pasteurization can effectively remove the bacteria in the milk and ensure the flavor of the milk, not to destroy the taste of the milk, the important thing is that the temperature change in pasteurization is drastic, three-stage heat transfer, are completed in a short time, that is, in the design, it needs to be designed in a heat exchanger, if the three-stage heat exchanger in one of the heat transfer is more difficult, In order to reduce the number of pieces, it is necessary to design a double or triple flow for this section.

Milk plate heat exchanger compared with most plate heat exchangers complex structure, a heat exchanger needs to flow through three kinds of media, after three or more heat exchange segments, milk heating will also produce deposits, in the case of complex heat exchange segments, easy to produce blockage phenomenon, and according to the requirements of food safety law, the whole need to use stainless steel material, the cost is relatively expensive, And the process is more complex.

Based on a wide variety of models, we can adapt to the needs of various complex working conditions, and a group of experienced design team, efficient and professional for customers to solve various problems, and has rich experience in Gasket Plate Heat Exchanger, Brazed Plate Heat Exchanger, Plate Heat Exchanger Gaskets, shell and tube heat exchanger.
