What are stainless steel plate heat exchangers and what are they used for?

Stainless steel plated heat exchangers are specially designed heat exchangers that provide heat transfer between fluids in a hygienic manner. They are preferred especially in the food industry due to their features of preventing bacterial growth and maintaining high hygiene standards. The most common area of use is in milk heating and cooling processes, but they are also used in many different food and beverage processes.

How do stainless steel plate heat exchangers work?

In these heat exchangers, fluids move between independent plates. The channel structure of the plates ensures that the fluids flow with high turbulence, creating a homogeneous heat distribution. Thus, efficient heat transfer occurs without mixing of the fluids. Thanks to this structure, both faster heating/cooling is achieved and energy saving is ensured.

What are the advantages of stainless steel plate heat exchangers in the food industry?

They ensure food safety and prevent bacterial formation thanks to their hygienic structures. Their easy-to-clean feature shortens cleaning and maintenance times in production processes. In addition, being made of stainless steel offers corrosion resistance and long-lasting use. These features provide safe and efficient pasteurization, especially for products such as milk, cream, whey, and fruit juice.

What are the most common applications of stainless steel plate heat exchangers?

In the most common milk pasteurization, they are used, but not limited to this. Cream pasteurization, whey processes, fruit juice production, brine processes, and a wide range of dairy products are preferred. In addition to food, it is also used for temperature control and heat recovery in sectors such as energy, HVAC, chemistry, and textiles.

Why are stainless steel plate heat exchangers preferred more than regular heat exchangers?

Different from regular heat exchangers, stainless steel plate heat exchangers ensure hygienic production conditions. Since cleanliness and safety of fluids used in the food industry are of utmost importance, stainless steel material is preferred. Additionally, due to its high heat transfer efficiency, it shortens process times, reduces energy costs, and provides longer-lasting use.

In which sectors can stainless steel plate heat exchangers be used?

It is used in many different fields such as the food industry, automotive, maritime, HVAC, petrochemical, pharmaceutical, metal industry, energy, and textile. It guarantees hygienic production in food, plays an important role in cogeneration and heat recovery in the energy sector, and takes on an important task in temperature control in processes in textiles. This diversity makes stainless plate heat exchangers a versatile and reliable solution.

Stainless Steel Plate Heat Exchangers

General Working Principle

Plate exchangers fundamentally consist of two inlet ports, channeled heat transfer plates, and two outlet ports. Two of these ports are for the entry and exit of the heating fluid, and the other two are for the entry and exit of the fluid to be heated. It is also possible to construct exchangers with more than one heating or to-be-heated fluid through special production.

Plate Exchanger

The function of the plates inside a plate exchanger is to transfer heat from the heating fluid to the fluid to be heated without mixing the fluids. The channeled structure of these plates enables the fluid to move in a highly turbulent manner. This turbulence causes a more homogeneous heat distribution, which leads to more efficient heat transmission.

Pasteurization Exchanger

Also known as pasteurization exchangers, these exchangers ensure homogeneous pasteurization by evenly distributing milk across their special stainless surfaces. Although milk is the first food product that comes to mind when mentioning a pasteurization exchanger, these exchangers are also used in the production of other dairy products and many different foods. Some of these include:
