Manufacturer Water to Water Stainless Steel 304 Gasket Plate Heat Exchanger for Food Industry

Product Description

The gasket plate heat exchanger is a kind of high efficiency and energy saving heat exchange equipment, which has many advantages such as high heat transfer efficiency, light weight, small footprint and easy maintenance. Mainly used in petroleum, chemical, beverage, medicine, urban central heating, light industry, textile, paper, oil and grease, shipbuilding, metallurgy, power (including nuclear power plants) and offshore engineering and other fields.

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.

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.
