How can dairies use their surplus milk? The obvious answer is to export it to those parts of the world where local demand outstrips supply. However, exporting billions of litres of UHT milk is neither the most cost-effective nor the most environmentally friendly way to go.
A better option is to turn it into powder first. Milk powder has a longer shelf life than UHT milk*, and, even when you take the energy used for drying milk powder into account, it compares favourably with the environmental cost of transporting UHT milk.
Thanks to our advanced, energy efficient evaporators and dryers, Tetra Pak is well placed to serve the growing milk powder industry. Our solutions are designed to capture economies of scale and meet producers' needs for efficient and economical production. We can make evaporators up to 20 metres high with fans driven by motors at 600 – 700 Kw and our spray dryers for dairy products are industry leading.
However, what's most unique about Tetra Pak is our knowledge of handling powder products. We use computational fluid dynamics (CFD) techniques to simulate trials before carrying out pilot tests in a physical plant. CFD also helps us create the optimal line design for each dairy, ensuring minimal consumption of energy and other utilities.
