Transporting milk from the farmer to the dairy involves challenges in precisely determining the amount of raw material, which determines, for example, subsequent financial settlements. When collecting milk from a supplier or entrepreneur, its quantity is measured using a volume measuring system installed in the road tanker.
It looks completely different in a dairy – here the quantity is counted by determining the volume based on e.g. measurement of a truck scale, milk density determined in the laboratory or by direct volume measurement using a measurement system based on electromagnetic flow meters. So the differences can be significant.

Determining the right amount of milk
The readings of measurement systems in tank trucks may differ from those given by the systems used in dairies.
– Production plants began to look for solutions that will not only be more accurate, but at the same time can improve processes or gain a competitive advantage in the form of production optimization or higher product quality. In this case, together with Hochland Polska in Węgrów, we obtained a reliable and repeatable solution, independent of weather conditions, and a much higher reception throughput. Ultimately, this resulted in a significant reduction in unloading time, thanks to which both Hochland and suppliers save time and money. – says Łukasz Wołoszyn, Industry Manager Food & Beverages from Endress+Hauser.
Precise mass flow meter
The use of a mass flow meter in a precise way will allow for the improvement of several fundamental processes, including: conducting direct measurements of mass, density and volume, making the measurements independent of atmospheric conditions, online density monitoring with the possibility of detecting milk dilution, automatic product recognition based on density (product or CIP) and resistance to aeration of milk and foam, and finally automatic unloading control ensuring the best repeatability.
“The use of this solution also made the measurements repeatable and there was no need for additional recalibration, which also depends on the season. Additionally, the use of such systems eliminates potential unfair practices of suppliers. All this leads to the improvement of ongoing and necessary processes," says Hochland Polska.

Modern control and measurement systems and… Almette cheese
Endress+Hauser has been cooperating with the Polish branch of Hochland for many years in several areas. The company supplies, among others: measurement control equipment used in production processes – from simpler solutions, such as pressure or temperature measuring devices, but also the most advanced ones for measuring turbidity, conductivity, density or pH.
One of them, especially provided for the Almette cottage cheese production process, was a pH measurement application. Continuous process measurement is crucial to conducting manufacturing in a way that ensures high quality and repeatability of production. The measuring system is a fully automatic set, adapted for automatic washing, which is important due to the need to maintain high hygiene of the process.
Endress+Hauser is also present in the area of media production and supply, where, among others, performs process measurements and monitors their consumption. Last year, a sewage pre-treatment plant was launched at the cheese factory in Węgrów, which used the solutions of a Swiss company.
– Since its launch, the installation has been operating as intended. We value long-term cooperation, professionalism, openness and flexibility of the solutions provided to us – sums up Cezary Szymaniak, Technical Development Manager at Hochland Polska.
