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.
