HRS Meets Tight Spec for Dairy Heat Exchanger
Burra Foods is a leading Australian dairy ingredient processor, producing value-added dairy products for the global food manufacturing market. An upgrade at their processing plant in Korumburra in the State of Victoria necessitated the use of a heat exchanger to help produce skimmed milk concentrate and cream from frozen concentrates which are then thermalised and cooled to ambient processing temperatures.
The required heat exchangers needed to raise the temperature of the product from -5°C to 18°C prior to the final heater, which includes melting the frozen product. After this the product is then cooled from 10°C to 5°C in the final cooler. Due to the viscous consistency the heat exchanger needed to resist fouling and provide good heat transfer performance, but existing building and infrastructure meant that the available space was severely limited.
The solution was an HRS MI Series corrugated tube heat exchanger which provided the necessary heating and cooling requirements in the tight space available and also resulting in a small pressure drop, another important consideration for this installation. Following an initial enquiry at the end of 2019, the unit was installed in mid-2020, and has exceeded performance expectations since final commissioning, with a production capacity of 5,000 kg of product per hour.
Stuart Shattock, Process Engineering Manager at Burra Foods comments: “Other suppliers couldn’t match HRS’s offering in terms of tubular heat exchangers and the level of detail provided. Once we placed the order, there was a slight delay due to Covid, but HRS managed to produce it as a rush order and the installation and commissioning was really smooth. In fact, they were able to accommodate a change to the process design partway through installation and make some improvements on the fly, which is great for a nimble and flexible food and beverage business like ourselves.”
