Processing region of 45,000 kg, saving such a cheese plant €54,000 a year. From Theory to Reality – Real World Advantages of Fines Reduction Among the cheese plants exemplifying the path to better returns and less waste is a major Scandinavian dairy producer. This large facility has an annual cheese output of approximately 70,000 tonnes. By replacing its existing lobe pump with a MasoSine Certa pump, the cheese manufacturer achieved an average fines reduction of 900g per tonne of manufactured cheese. When multiplying the annual output of 70,000 tonnes by 900 g per tonne, the additional annual yield is 63 tonnes of cheese. With a price difference as much as approximately €1.20 per kg, the cheese plant is enjoying increased profit of €76,000 per annum thanks to its new investment. Moisture Retention The story is similar when scrutinising moisture content versus dry matter. According to the same customer trials, using MasoSine Certa pump technology rather than a centrifugal pump will see a better retention of moisture (whey) within the curd after pumping. In addition, the increased weight (yield) of cheese curd will amount to circa 5 tonnes per year. With an average price per kilogram of cheese at €3.00, the annual savings will be €15,000. Cutting Fat Producing 50,000 tonnes of cheese a year requires around 400 million litres of milk. Trials indicate that the average reduction of fat (cream) content in the whey when using a MasoSine Certa pump is around 0.03%. This is beneficial because the higher the fat content of the whey, the worse the result after it is pumped. As the proportion of whey to curd is about 80%, the cheese plant can save around 96,000 litres of fat per year, equating to savings of €96,000 based on a price per litre of €1.00. Total Savings from Reducing Fines, Dry Matter, & Fat Combining saving, our theoretical cheese plant producing 50,000 tonnes of cheese a year can potentially expect the following from its investment in a MasoSine Certa pump: • Total annual savings of €165,000 from fines, moisture content versus dry matter, and fat • A return on investment for its MasoSine Certa pumps in just 8 months Reducing Processing Costs and Increasing Yields – A Case Study A market-leading cheese maker based in Denmark is showing how to boost yields and cut the costs of cheese processing through astute investment in optimised pump technology. The existing lobe pumps were causing two key problems. Firstly, shear damage from lobe pumps meant increased fines were entering the whey stream and reducing yield. The second issue was their limited suction capability. Reduced suction causes system cavitation that can lead to broken pipe joints and welds, increasing maintenance and unplanned downtime. Installing two MasoSine Certa pumps led to significant fines reduction as they treated the fragile cheese curd more gently and caused less damage. In each tonne of cheese produced, MasoSine Certa pumps gave 2.552 kg of fines per tonne of cheese compared to the 3.481 kg produced by lobe pumps, saving 0.929 kg fines per tonne, equating to a 27% reduction in lost cheese fines. The dairy produces 70,000 tonnes of cheese every year. Using the MasoSine Certa pump, an extra 65 tonnes of cheese is produced annually (0.929 kg/t x 70,000 tonnes = 65,030 kg) with a value of DKK 780,000 (approximately €105,000). As a result, the dairy’s CAPEX investment for the two new MasoSine Certa pumps achieved ROI in just 9 months. Soft Cheese Successes – A Case Study When pumping sensitive curds, it’s vital to convey them as gently as possible. Otherwise, strong shear results in cheese dust, risking a reduction in yield and quality. With these thoughts in mind, a major 26 food Marketing & Technology • June 2022

Processing mozzarella dairy in Switzerland wanted to replace its previous time-consuming and laborious transfer of curd/whey mixture into filling tubs with a highperformance feed pump that would transfer the mix directly into a new drainage system via pipes. Searching for the most suitable pump for the task, the cheese plant’s milk technologist and production manager for cream cheese pooled their knowledge to design a series of comprehensive tests with different pump types, including: • A centrifugal pump • Air operated diaphragm pump (AOD) • A twin screw pump • A MasoSine Certa pump from WMFTS By carefully dimensioning the pumps, all candidates met the specified production time of around two hours for a batch, transferring 5,000 litres in under 25 minutes. However, when analysing the results, considerable qualitative differences quickly became apparent. Conclusion The cheese market is poised for strong growth, providing manufacturers invest in technologies that boost efficiency and cut product loss to remain competitive and make the most of growing demand. There is strong evidence that the cheese sector can benefit from carefully considered investment in the latest sinusoidal pump technology. The advantages relating to improvements in yield, as well as savings in energy, water and fines, deliver a boost to both bottomline profitability and sustainability. fmt 1.McKinsey - What’s next for dairy?

Due to its geometry, the screw pump reduced broken grain size. Processing finer curd is undesirable due to the poor quality of the resulting cheese. The clear winner was the MasoSine Certa pump, which achieved the highest yield and the lowest loss due to cheese fines and the fat remained in the curds. Product quality also improved from the gentle pumping of sinusoidal technology. Based on the annual usage of 46 million litres of milk and a reduction in whey fat content of 0.1%, the mozzarella dairy is benefitting from impressive annual savings of CHF 294,400. This calculation is based on a yearly reduction in whey fat content of 36,800 kg (at a cream fat price per kg of CHF 8). As a result, it took just 1.4 months to achieve ROI for the MasoSine Certa pump. food Marketing & Technology • June 2022 27
