Pillow Plate applications for the Dairy Industry

Omega Thermo Products is the world’s largest manufacturer of Pillow Plates for milk cooling tanks. In order to deliver quality milk products, it is important that the vessel is cooled evenly and to the right temperature. In addition, the cooling of dairy products must comply with all kinds of legal regulations. This applies to milk coming directly from the cow as well as for dairy products such as yoghurt, custard, cheese or cream which are processed in the dairy factories. Omega Thermo Products has years of experience in the process-oriented design and production of Pillow Plates for the dairy industry.

Milk tanks at the farms

When cows are milked, the milk has to be cooled from 35° C to 4 °C within 3 hours. Depending on the number of times per day that you milk, you calculate how much cooling surface is needed (Omega Pillow Plate) to cool the milk within the established time limit.
Many smaller dairy farms in Western Europe merge into bigger farms with a larger stock of cattle. At these companies, traditional milk tanks are slowly being replaced by larger milk silos.

Directly cool milk through Omega Pillow Plate

Our Pillow Plates are applied in different ways in the dairy industry. In all methods the inner tank is manufactured from Pillow Plates. In the case of a horizontal tank, the lower half of the tank is cooled. In smaller, open vessels, the bottom half is equipped with Pillow Plates.
To determine the cooling surface for the milk silos, we often make a heat transfer calculation. After performing this calculation, we present an implementing proposal to our customer. This proposal contains the required surface, the design and the finishing connection diameters.

  • Omega Pillow Plate is manufactured with the protective foil on the product side of the tank 
  • The protective foil can be removed without leaving any glue residues when the tank is assembled
  • This foil guarantees good quality plate inside of the tank
  • Flexible welding process ensures very efficient heating and cooling
  • Optimal heat transfer due to turbulent flow in the jacket

In addition to cooling, Omega Pillow Plates are suitable for heating to temperatures up to 320 °C.
With years of experience in the dairy industry and many customers in this sector, our engineers can quickly calculate the type of Pillow Plate you need to cool your product.


Heat Exchangers for the diary industy 
In dairy factories, the product is often heated or cooled using indirect heat exchangers, as there is a short timeframe to cool the product. Therefore, an Omega Falling Film Water Chiller is a good solution. But an Immersion Chiller or Ice Bank can also be interesting if you want to make a trough current and avoid energy peaks.

We supply our appliances to worldwide producers in the dairy industry. If you want to know more about our range of options, our engineers will gladly discuss the possibilities with you.
