EFFICIENCY PLANT MVR
Galbani, establishment of Corteolona PV
Replacement of traditional impeller with Perfettibile® Turboimpeller
The plant in question evaporates water at 27% from milk whey. The installed Turbofan was of traditional type with an impeller of 1980 mm of effective diameter, with 9 curved backward blades.
The objective of revamping was the achieving of 10% reduction of the absorbed power during the whole production year which is normally around the 30 consecutive hours of operation.
Process data under baseline conditions:
-Qm 42000 kg/h
- ΔT 3,3°C
-Vapour temperature 64°C
Beginning from process data and with the help of the advanced tools that Perfettibile® provides, it has been designed a new Turboimpeller that could satisfy process data with a lower energy consumption. The replacement of the impeller only enabled us to contain intervention costs maximising the performance of the new Turboimpeller. In the months following intervention, the Turbofan's energy consumption has been monitored continuously. The average value measured far exceeded the target.
During the early stages of the process, when the plant is still clean, the saving reaches peaks of 20%, but at the end of the production year the average value recorded is 14%.
